	  libdirac_encoder/picture_compress.h,
	  libdirac_encoder/seq_compress.cpp,
	  libdirac_encoder/seq_compress.h: Subgroups will now switch to PPP

	  The ratio of intra blocks is used to determine whether a P
	  picture contains large or poorly matched motions. If so the
	  subgroup terminated by that P is switched to all pictures.

	* libdirac_motionest/: me_mode_decn.cpp, me_utils.cpp, me_utils.h:
	  Modified intra selection to use a Haar transform.

	  A Haar transform is applied to the difference array after
	  subtracting the DC value. This penalises blocks where there is a
	  lot of structure, but not blocks which are close to the DC value.

	* libdirac_common/motion.cpp, libdirac_common/motion.h,
	  libdirac_encoder/enc_picture.cpp, libdirac_encoder/enc_picture.h:
	  Added support for being able to drop a reference from an inter
	  picture.

	  If it's determined that a reference is unlike the current
	  picture, any matches might be accidental and could reduce
	  quality. So being able to drop references could be useful.

	  complexity metric based on variance of prediction residue.  Added
	  intra block ratio to MEData class.  Defined a complexity measure
	  based on pel ME SAD values.  Pixel accurate motion estimation
	  done using look ahead.  Encoder now preloads a queue of frames.

	  compressor engine.  Separated out prefiltering.  Incorporated
	  wavelet coefficient data into Picture class.	Moved subband
	  metadata into CoeffArray class.  Further splitting of picture

	  SequenceHeaderByteIO for spec consistency.  Fixed bug with motion
	  data being incorrectly coded.  Added ME data to the EncPicture
	  class.  Fixed unit test for motion compensation.  Renamed
	  EncBuffer class as EncQueue class to make Andrea happy.  Fixed
	  buffers to be mere wrappers around vectors of pointers. Partially
	  fixed unit tests.  Change frame to picture names.  Fixed for
	  compatibility with buffer interfaces.  Simplified buffer memory
	  management.  Simplified buffer operation for decoder.  Changed
	  default qf to 5.5 Synched with cvs for libdirac_decoder Updated
	  against current cvs in libdirac_{byteio,common} Changed GOP L1
	  refs to reduce "breakthrough" Refactored to use encoder picture
	  and encoder buffer classes.  Added classes for encoder pictures
	  and specialist buffer.  Simplified picture class.  Refactor to
	  make subclassing easier.  Fixed interlace IO errors.	Refactored
	  so as to remove encoder-specific methods from picture buffer.
	  Modified picbuffer so that decoder solely manages picture params
	  and GOP.  Modified makefile for encoder picture class.

	* doc/latex_spec/: bs-spec.tex, idwt.tex, layout-fullsize.tex,
	  quant-matrix.tex, spec-structure.tex: Fixed typos in wavelet
	  lifting spec and changed Debuc to Dubuc.

	  Also incremented version ready for release.

2008-06-23 20:48  asuraparaju

	* win32/:
	  VS2003/DiracEncoder/libdirac_encoder/libdirac_encoder.vcproj,
	  VisualStudio/DiracEncoder/libdirac_encoder/libdirac_encoder.vcproj:
	  Add enc_picture.cpp{.h} and enc_queue.cpp{.h} to the sources
	  list.

2008-06-20 20:03  asuraparaju

	* libdirac_encoder/seq_compress.cpp: Check that future pictures
	  exist in the picture buffer before using them as references for
	  the current picture.

2008-06-19 20:39  tjdwave

	* util/instrumentation/libdirac_instrument/: draw_overlay.cpp,
	  gm_inliers.cpp, motion_arrows.cpp, motion_colour.cpp,
	  motion_colour_arrows.cpp, overlay.cpp, pred_mode.cpp, sad.cpp,
	  split_mode.cpp: Fixed instrumentation to comply with new class
	  methods.

2008-06-19 20:36  tjdwave

	* unit_tests/: frames_test.cpp, motion_comp_test.cpp: Fixed test to
	  conform to class changes.

2008-06-19 20:35  tjdwave

	* libdirac_motionest/: me_mode_decn.cpp, me_mode_decn.h,
	  me_subpel.cpp, me_subpel.h, motion_estimate.cpp,
	  motion_estimate.h, pixel_match.cpp, pixel_match.h: Fixes due to
	  use of EncQueue/EncPicture class. Changed "frame" to "picture"
	  terminology.

2008-06-19 20:33  tjdwave

	* libdirac_decoder/: comp_decompress.h, dirac_parser.cpp,
	  picture_decompress.cpp, seq_decompress.cpp: Fixes due to changes
	  in PictureBuffer and Picture classes.

2008-06-19 20:28  tjdwave

	* libdirac_encoder/: prefilter.cpp, quality_monitor.cpp,
	  quality_monitor.h: Mods due to EncQueue/EncPicture class changes.

2008-06-19 20:25  tjdwave

	* libdirac_encoder/: picture_compress.cpp, picture_compress.h:
	  Modified for change to EncQueue/EncPicture classes.

2008-06-19 20:22  tjdwave

	* libdirac_encoder/: seq_compress.cpp, seq_compress.h: Moved GOP
	  structure determination into this class.

	  Also, changed the class so that it used the EncQueue/EncPicture
	  classes.

2008-06-19 20:17  tjdwave

	* libdirac_common/: pic_io.cpp, pic_io.h: Refactored to comply with
	  changes to Picture class.

2008-06-19 20:14  tjdwave

	* libdirac_common/: common.h, common.cpp: Removed unnecessary
	  constructor.

2008-06-19 20:12  tjdwave

	* libdirac_common/: mot_comp.cpp, mot_comp.h: Changed interface.

	  Interface changes because EncQueue class is not a subclass of
	  PictureBuffer.

2008-06-19 20:10  tjdwave

	* libdirac_common/: picture.cpp, picture.h: Minor refactor to
	  remove "redo" metadata.

	  The picture buffer deletes and reallocates data now, so we don't
	  need to reconfigure/reinitialise a picture. So we can lose the
	  tracking metadata.

2008-06-19 20:07  tjdwave

	* libdirac_common/: picture_buffer.cpp, picture_buffer.h:
	  Refactored so that the class is a simple wrapper around a vector
	  of pointers.

	  Removed all the GOP functionality so that it is done in the
	  sequence compressor class.

2008-06-19 20:05  tjdwave

	* libdirac_encoder/Makefile.am: Added new files.

2008-06-19 20:02  tjdwave

	* libdirac_encoder/: enc_picture.cpp, enc_picture.h, enc_queue.cpp,
	  enc_queue.h: Added classes for encoder picture and encoder
	  picture queue.

	  The encoder picture subclasses a basic picture and adds original
	  data as well as coded data. An encoder queue is a queue of
	  encoder pictures, so separate queues/buffers for original and
	  motion estimation data are not needed.

2008-06-18 16:00  asuraparaju

	* extras/dirac_dshow/src/diracsplitter/: DiracSplitter.cpp,
	  DiracSplitterFile.cpp, DiracSplitterFile.h: Modified the code so
	  that the Dirac decoder module of the the filter can connect to
	  splitters (e.g. AVI splitter) other than the Dirac splitter. We
	  can now play back AVI files containing Dirac muxed with audio.

2008-06-18 11:16  asuraparaju

	* encoder/encmain.cpp: Add command line argument -h or -help to
	  display usage info.

	  libdirac_encoder/seq_compress.cpp,
	  libdirac_encoder/seq_compress.h: Added support for various forms
	  of prefiltering.

	  Prefiltering using rectangular, diagonal or centre-weighted
	  median filtering is now available as a command-line option.
	  Rectangular and diagonal low-pass filtering are both adaptive,
	  with strength determined by the QF and also a strength parameter
	  added on the command line. Centre-weighted median filtering is
	  non-adaptive, but adjusts the centre weight according to the
	  strength parameter.

	  Usage is :

	  dirac_encoder ... -prefilter FILTER_NAME n ....

	  where FILTER_NAME is one of NO_PF, CWM, RECTLP, DIAGLP and n is
	  from 0 to 10.  NO_PF means no prefilter.

	  libdirac_encoder/quality_monitor.h,
	  libdirac_encoder/quant_chooser.cpp,
	  libdirac_encoder/seq_compress.cpp: Various refactorings and
	  bug-fixes.

	  1. Changed how padding is implemented so that padding is only
	  added to the coefficient array before the wavelet transform, and
	  is removed from the coefficient array immediately after the
	  wavelet transform.  No metadata for "OrigXl" etc is needed now.

	  2. Various places "frame" is changed to "picture" and "fparams"
	  to "pparams" etc.

	  3. Fixed bug with misreporting bit rate for long sequences by
	  recording data with int64_t not int.

	  4. Fixed a bug with perceptual weighting where additional weight
	  was being given to the DC band even though it is coded
	  losslessly. This threw out weights for the other bands when the
	  weights were normalised, especially for intra pictures. In turn
	  this required that the relative lambdas used for different
	  picture types had to be changed.

	  libdirac_encoder/rate_control.h,
	  libdirac_encoder/seq_compress.cpp: Modified rate control. The
	  rate control no longer crashes when it inserts intra pictures:
	  the picture bits in this case are allocated to the _scheduled_
	  picture type. A tentative buffer model has been re-introduced
	  whereby the GOP allocation is adapted slowly to reduce
	  overshoots, and quickly to reduce undershoots. The buffer target
	  occupancy is set to 90%, and once every GOP this is corrected for
	  bit rate overshoots, and once every subgroup (i.e. much faster)
	  it is corrected, by a larger amount, for bit rate undershoots. In
	  addition, if the bit rate for a particular frame is <50% of the
	  target bit rate, an emergency reallocation is applied.

	  The frame compressor and sequence compressor classes have been
	  re-arranged so that the frame compressor manages quantisation
	  selection. This will allow the rate controller to be modified
	  with look-ahead, changing QF values ahead of time based on
	  estimated bit rate for residuals, as well as on the results of
	  motion estimation. At the moment it's still pure feedback
	  however.

	  Performance on difficult pictures has also been improved by
	  increasing the quality of inserted I frames, and increasing the
	  premium given to pictures with a large number of intra blocks.

	  Quantiser selection has also been tidied a little.

	  codeblocks is always coded for each level. This means that the
	  "default spatial partition" flag is removed from the code and the
	  spec.

	  motion_arrows.cpp, motion_colour.cpp, motion_colour_arrows.cpp,
	  overlay.cpp, pred_mode.cpp, sad.cpp, split_mode.cpp: Treat all

	* libdirac_common/frame.cpp, libdirac_common/pic_io.cpp,

2007-08-23 16:05  tjdwave

	* doc/latex_spec/mc.tex: Changed clipping for motion compensation

2007-08-23 16:02  tjdwave

	* doc/latex_spec/: bs-spec.tex, picture-dec.tex,
	  ref-default-videoparams.tex, vidsys.tex: Initial mod to show that
	  video signals in Dirac should now be considered bipolar. Clipping
	  therefore applies to the range [-2^{N-1}, 2^{N-1}-1]

2007-08-21 13:46  asuraparaju

	* libdirac_common/frame_buffer.cpp,
	  libdirac_encoder/seq_compress.cpp: Fix errors reported by
	  valgrind where unitialiased data was being read from upconverted
	  arrays. The upconverter uses the actual frame dimensions and not
	  the padded dimensions whereas the ME engine uses the padded
	  dimensions which is resulting in unitialised data reads. The
	  motion estimation frame buffer now holds the actual frames rather
	  than the padded frames to overcome this problem.

2007-08-21 13:42  asuraparaju

	* libdirac_common/: arrays.h, frame.cpp, frame.h: New functions to
	  copy contents of one frame to another without altering the
	  dimensions of the destination frame. The destination frame is
	  padded with the last true value in the source frame if it is
	  bigger than the source frame.

2007-08-13 11:41  tjdwave

	* libdirac_encoder/seq_compress.cpp: Typo.

2007-08-13 11:30  tjdwave

2007-08-13 11:30  tjdwave

	* libdirac_encoder/frame_compress.cpp: Removed superfluous SAD test
	  in cut detection.

2007-08-13 11:29  tjdwave

	* libdirac_motionest/me_mode_decn.cpp: Changed anti-intra bias to
	  10%: i.e. intra only needs to be 10% better in SAD terms to be
	  chosen, rather than 20%. This (slightly) improves ME mismatches.

2007-08-07 14:19  tjdwave

	* doc/latex_spec/idwt.tex: Clarified IDWT filtering definition.

2007-08-02 15:22  tjdwave

2007-07-31 16:13  tjdwave

	* libdirac_encoder/: rate_control.cpp, rate_control.h: Bug fixes.
	  Fixed problem with int32 overflow with very high bit rates.
	  Fixed problem with non-integral frame rates being incorrectly
	  set.

2007-07-30 19:40  asuraparaju

	* libdirac_common/motion.cpp: Initialise intra costs and dc arrays
	  to prevent uninitialised read error and memory hogging in
	  intrumentation utilities.

2007-07-26 13:56  tjdwave

	* libdirac_motionest/me_mode_decn.cpp: Improve Intra mode selection
	  routine. Incorrect RDO modelling of mode selection has been
	  removed, and intra is only selected if a) motion compensated
	  error is not very small, and b) intra gives a substantial SAD
	  improvement.

2007-07-26 13:53  tjdwave

	* unit_tests/wavelet_utils_test.cpp: Adapted unit test to support a
	  coefficient array being passed to the transform.

2007-07-26 13:49  tjdwave

	* libdirac_encoder/dirac_encoder.cpp: Added class to cope with
	  array types being different.

2007-07-26 13:47  tjdwave

	* encoder/encmain.cpp: Supports higher wavelet depth when MMX is
	  not used.

	  libdirac_encoder/comp_compress.h,
	  libdirac_encoder/quant_chooser.cpp,
	  libdirac_encoder/quant_chooser.h: Added CoeffType and CoeffArray
	  types for wavelet coefficients and arrays of coefficients. For
	  MMX optimisation, CoeffType will be short, but otherwise it will
	  be int. In this way large wavelet depths can be supported.

2007-07-26 13:39  tjdwave

	* libdirac_encoder/rate_control.cpp: Fixed correct initialisation
	  of QF when CBR is used.

2007-07-25 14:26  asuraparaju

	* libdirac_common/common.h: Remove all references to oicturen
	  number in access unit.

	* doc/latex_spec/: bs-spec.tex, layout-fullsize.tex: Updated parse
	  codes and version number. _pre8 will now be released.

2007-07-18 09:14  tjdwave

	* libdirac_common/: band_codec.cpp, wavelet_utils.cpp: Clarified
	  parent-child relationship and context selection. No parent is now
	  assigned to the lowest 4 subbands and the context selection just
	  depends on the parent value, which is set to zero when there is
	  no defined parent band.

2007-07-17 09:46  tjdwave

	* libdirac_common/common.cpp: Fixed bug with 60 fps video.

2007-07-17 09:27  tjdwave

	  longer incluse the Picture Number of the 1st frame that follows
	  the Access Unit Header.

2007-07-05 15:13  tjdwave

	* doc/latex_spec/: bs-spec.tex, core-wlt-dec.tex, lifting.tex,
	  quant-matrix.tex, spec-structure.tex: Removed the AU Picture
	  Number, which now serves no purpose. Also added parse code and
	  operation for doing intra coding without arithmetic coding.  This
	  latter is still to be agreed.

2007-06-21 14:16  tjdwave

	* doc/latex_spec/: lifting.tex, quant-matrix.tex,
	  spec-conventions.tex, spec-structure.tex: Added quantisation
	  matrices for low delay syntax and informative text on
	  quantisation strategies - also an informative annex on Lifting.

2007-06-21 14:13  tjdwave

	* libdirac_encoder/rate_control.cpp: [no log message]

2007-06-21 12:01  tjdwave

	* libdirac_encoder/rate_control.cpp: Experimental rate control for
	  intra-only coding. This uses a recursive filter to adjust the
	  quality factor. The rate of convergence is adaptive, depending on
	  the difference between the actual and target quality, which
	  overcomes the usual lag of recursive filtering. When the
	  difference is large, convergence is steady. When it is relatively
	  small, convergence is very rapid.

2007-06-20 15:42  tjdwave

	* encoder/encmain.cpp, libdirac_common/common.cpp,
	  libdirac_common/common.h, libdirac_encoder/dirac_encoder.cpp,
	  libdirac_encoder/dirac_encoder.h,

	  libdirac_motionest/me_mode_decn.cpp,
	  libdirac_motionest/pixel_match.cpp,
	  libdirac_motionest/pixel_match.h: Added support for full-search
	  block matching. This is controlled by using the flag

	  -full_search [xr] [yr]

	  to do an initial pixel-accurate search in the range
	  [-xr,xr]x[-yr,yr].  Sub-pixel refinement is unaffected.

	  Mode decision and the standard hierachical block match have been
	  slightly changed to improve performance.

2007-06-18 17:05  asuraparaju

	* libdirac_common/wavelet_utils_mmx.cpp: Corrected name of DD9_3
	  filter to DD9_5 to be in sync with non-mmx version of this file.

2007-06-18 16:24  tjdwave

	* doc/specification.html, encoder/encmain.cpp,

	  libdirac_common/wavelet_utils.cpp,
	  libdirac_common/wavelet_utils.h,
	  libdirac_decoder/frame_decompress.cpp: Corrected name of DD9_3
	  filter to DD9_5. Changed weights for (13,5) to correspond to
	  analysis rather than synthesis filter. This seems to give
	  slightly better results even with perceptual weighting.

2007-06-18 16:22  tjdwave

	* doc/latex_spec/: bs-spec.tex, idwt.tex, low-delay.tex,
	  quant-matrix.tex, ref-default-videoparams.tex,
	  spec-structure.tex, state-macros.tex: Added default quantisation
	  matrices. Also changed name of DD (9,3) filter to (9,5) filter as
	  these are the correct filter lengths.

2007-06-10 17:19  asuraparaju

	* libdirac_decoder/comp_decompress.cpp: Fix unintialised value bug
	  reported by valgrind.

	  libdirac_encoder/frame_compress.cpp,
	  libdirac_encoder/seq_compress.cpp, unit_tests/frames_test.cpp,
	  unit_tests/motion_comp_test.cpp: Modified FrameParams class to
	  include the original frame dimensions in addition to the padded
	  (for dwt) dimensions. All operations in the decoder other than
	  the inverse wavelet transform are now performed using the
	  original frame dimensions.

2007-06-10 14:47  asuraparaju

	* libdirac_byteio/dirac_byte_stream.cpp: Fix memory leak reported
	  by valgrind. Minor indentatiion changes.

	* doc/latex_spec/: bs-spec.tex, mc.tex: Fixed bug with chroma MV
	  scaling so that it now agrees with Dirac and Schro codebase.

	* libdirac_encoder/: frame_compress.cpp, frame_compress.h,
	  rate_control.cpp, rate_control.h, seq_compress.cpp: Modified
	  constant bit-rate operation, so that when a cut is detected the
	  long-term qf is used, instead of the current one in the rate
	  model.  This has the effect of reducing quality crashes and rate
	  explosions.

2007-05-15 13:40  asuraparaju

	* Makefile.am: In addition to the regular targets (all, check,
	  valgrind-check), added the following new targets

	  Print GOP bit-rate statistics to standard output only in verbose
	  mode.

2007-05-03 15:39  asuraparaju

2007-05-02 17:30  asuraparaju

	* win32/: VS2003/libdirac_byteio/libdirac_byteio.vcproj,
	  VisualStudio/libdirac_byteio/libdirac_byteio.vcproj: Include
	  mydataelement_byteip.cpp{.h} to source list.

2007-05-02 17:29  asuraparaju

	* libdirac_common/common.cpp: Include inttypes.h to fix g++ 3.3.x
	  and icc warnings regrading uint64_t.

2007-05-02 14:10  asuraparaju

	* libdirac_byteio/parseunit_byteio.cpp,
	  libdirac_byteio/parseunit_byteio.h,
	  libdirac_decoder/dirac_cppparser.cpp: Handle auxiliary/paddaing
	  data parse units and low-delay frames. Auxiliary/ padding data
	  parse units are ignored by the decoder. When the decoder
	  encounters a low-delay frame it exits with an error message.

2007-05-02 09:52  tjdwave

	* libdirac_encoder/comp_compress.cpp: Fixed bug with using
	  -multi_quants -lossless : multiquants were being signalled, but
	  quantisers for each code block weren't being coded.

2007-05-01 15:51  asuraparaju

	* libdirac_common/band_codec.h, libdirac_encoder/comp_compress.h:
	  Fix warnings reported by doxygen when not all parameters to a
	  function are documented.

2007-05-01 10:56  tjdwave

	* libdirac_common/wavelet_utils.cpp: Fixed bug in calculating
	  subband weighting coefficients: values for compensating filter
	  gains were incorrect.

2007-04-30 14:13  tjdwave

	* doc/latex_spec/dataenc.tex: Fixed table warning

2007-04-26 14:56  asuraparaju

	* libdirac_common/frame_buffer.cpp, libdirac_common/frame_buffer.h,
	  libdirac_decoder/frame_decompress.cpp,
	  libdirac_decoder/seq_decompress.cpp: Added new function to
	  FrameBuffer to check if  frame is available before using it. This
	  is to prevent from trying to dereference a non-existent first
	  frame from the buffer. This function is a temporary fix.
	  FrameBuffer might need to be re-written to return pointer to a
	  frame in the buffer rather than a reference so that the return
	  value can be checked for NULL before using it.

2007-04-25 11:49  tjdwave

	* doc/latex_spec/profilelevel.tex: Revised text on levels and
	  profiles.

2007-04-24 16:42  tjdwave

	* doc/latex_spec/: arith.tex, bs-spec.tex, dataenc.tex,
	  layout-fullsize.tex, low-delay.tex, sourcepresets.tex,
	  spec-conventions.tex, wlt-dec.tex: Removed superfluous parse
	  codes and added a parse code for padding data.  Removed reference
	  to using_ac and using_mc flags/functions: low-delay syntax is now
	  vlc-only, and without motion compensation; core syntax supports
	  both motion compensation and arithmetic coding.

2007-04-24 10:35  tjdwave

	* doc/latex_spec/: sourcepresets.tex, state-macros.tex, vidsys.tex:
	  Refactored the source parameter appendix to get rid of remaining
	  conversion artefacts.

2007-04-23 15:52  tjdwave

	* doc/latex_spec/: bs-spec.tex, dataenc.tex, low-delay.tex,

	  flag extra warnings.

2007-04-18 13:28  tjdwave

	* doc/latex_spec/: arith.tex, bs-spec.tex, dataenc.tex, idwt.tex,
	  layout-fullsize.tex, low-delay.tex, motion-dec.tex,
	  picture-dec.tex, spec-conventions.tex, vidsys.tex, wlt-dec.tex:
	  Incorporated Dave Schleef's comments and bugfixes.

2007-04-17 16:50  tjdwave

	* doc/latex_spec/: layout-fullsize.tex, vidsys.tex: Further update
	  to video systems model, covering YCoCg coding and colour
	  matrixing etc. YCoCg has been changed to give an additional bit
	  to Y so that luma and chroma have the same resolution, to avoid
	  confusion.

2007-04-16 17:17  tjdwave

	* doc/latex_spec/: vidsys-colourmatrix.tex, vidsys.tex: Initial
	  mods to video systems model to bring it up to date: mostly done
	  colour.

2007-04-16 16:42  tjdwave

	* doc/latex_spec/: arith.tex, bs-spec.tex, dataenc.tex, idwt.tex,
	  intro.tex, layout-fullsize.tex, low-delay.tex, motion-dec.tex,
	  picture-dec.tex, spec-conventions.tex, state-macros.tex,
	  wlt-dec.tex: Removed mention of Y,U and V - instead use Y, C1 and
	  C2. Fixed bug with biased rounding in IDWT, and fixed bug with
	  ref2 motion vector decoding.

2007-04-16 12:17  tjdwave

	* doc/latex_spec/arith.tex: Finalised informative text on
	  arithmetic encoding. Minor bug fixes.

2007-04-11 17:26  asuraparaju

	* libdirac_encoder/comp_compress.cpp: Initialise the multi-quants
	  flag and estimated bits for DC band to fix bug where decoder
	  output was not matching locally decoded output.

2007-04-11 17:23  asuraparaju

	* libdirac_common/video_format_defaults.cpp,
	  libdirac_encoder/seq_compress.cpp: Fix initialisation errors
	  reported by valgrind.

2007-04-11 16:28  tjdwave

	* doc/latex_spec/: arith-encoder.tex, arith.tex, bs-spec.tex,

	  ref-default-videoparams.tex, sourcepresets.tex,
	  spec-structure.tex, state-macros.tex, stream-access.tex,
	  wlt-dec.tex: Modified arithmetic coding sections to place the
	  arithmetic coding engine in an annex. The AC system now agrees
	  with the code, using the LUT update implementation.

	  Various compile warnings also fixed.

2007-04-11 15:36  tjdwave

	* libdirac_common/arith_codec.h: Minor cosmetic change to simplify
	  symbol decoding and agree with AC theory.

2007-04-11 15:18  tjdwave

	* libdirac_encoder/frame_compress.cpp,
	  libdirac_common/mv_codec.cpp: Fixed bug with motion vector coding
	  on long sequences.

2007-04-11 09:08  tjdwave

	* decoder/decmain.cpp, encoder/encmain.cpp,
	  libdirac_byteio/Makefile.am, libdirac_byteio/mvdata_byteio.cpp,
	  libdirac_byteio/mvdata_byteio.h,
	  libdirac_byteio/mvdataelement_byteio.cpp,

	  libdirac_decoder/frame_decompress.cpp,
	  libdirac_decoder/frame_decompress.h,
	  libdirac_encoder/frame_compress.cpp,
	  libdirac_encoder/frame_compress.h,
	  libdirac_encoder/quality_monitor.cpp: Motion vector data is now
	  split into a number of different parts which are coded as
	  separate units:

	  - Superblock/macroblock splitting mode - Block prediction mode -
	  Motion vectors, reference 1, horizontal component - Motion
	  vectors, reference 1, vertical component - Motion vectors,
	  reference 2, horizontal component - Motion vectors, reference 2,
	  vertical component - DC values, Y - DC values, U - DC values, V

	  Each is a separate, byte-aligned element with a prefixing length
	  code.

	  This allows parallel encoding and decoding of these elements,
	  especially beneficial in hardware.

	  Still TO DO: gather statistics on each of these elements
	  separately.

2007-04-11 08:52  tjdwave

	* libdirac_encoder/: comp_compress.cpp, quant_chooser.cpp: Fix to
	  stop drift on sequences of still frames: at high rate, DC bands
	  were being erroneously skipped, causing a build-up of dc error.
	  This fix means that DC bands are always coded losslessly and
	  never skipped. Further experiments may be required to see if this
	  condition can be relaxed.

2007-04-04 17:00  tjdwave

	* doc/latex_spec/: arith.tex, mc.tex, motion-dec.tex,
	  spec-conventions.tex, state-macros.tex: Changed motion data
	  coding specification to allow for parallel decoding of motion
	  data elements.

	  Fixed bugs in arithmetic coding spec - this will be refactored to
	  reflect recent code changes soon.

2007-04-04 09:11  tjdwave

	* doc/latex_spec/bs-spec.tex: Fixed the next parse offset and
	  previous parse offset to be 4 bytes instead of 3. This is now in
	  line with the code.

2007-04-04 09:08  tjdwave

	* doc/latex_spec/wlt-dec.tex: Updated quantisation factors so that
	  they represent an integer approximation of 2^{(q/4)+2)} up to
	  q=128. Now agrees with code.

2007-04-03 16:29  tjdwave

	* doc/latex_spec/: arith.tex, motion-dec.tex, state-macros.tex,
	  wlt-dec.tex: Minor bug-fixes.

2007-04-03 14:06  asuraparaju

	* extras/dirac_dshow/src/diracsplitter/DiracSplitterFile.cpp: Size
	  of the parse unit header has increased to 13.

2007-04-03 14:04  asuraparaju

	* tests/samples.at: Define a variable mv_prec to set the motion
	  vector precision on the encoder command line. Values is currently
	  hardcoded to quarter pixel. Change the value of variable mv_prec
	  to run the tests with a different value.

2007-04-03 14:02  asuraparaju

	* libdirac_motionest/motion_estimate.cpp, libdirac_common/common.h:
	  Hack to support pixel accurate motion estimation. The pixel
	  accurate motion vectors are multipled by 2 and then half-pel
	  accurate motion estimation is performed. After ME, he motion
	  vectors are divided by 2 to convert them back to pixel accurate
	  motion vectors.

2007-04-02 08:58  asuraparaju

	* libdirac_common/arith_codec.cpp: Fix g++ warnings regarding order
	  of initialisation of member variables in ArithCodecBase
	  constructor.

2007-03-30 18:22  timborer

	* libdirac_common/: arith_codec.cpp, arith_codec.h: Simplified
	  probability estimation for arithmetic coding to speed up encoding
	  and decoding.  Now the total symbol count is ASSUMED to be a
	  function of the current probability. The update is implemented in
	  a lookup table for speed. The total symbol count is assumed to be
	  16 when probabilit of 0 is 0.5, and assumed to be 256 when prob 0
	  is 1.

2007-03-29 17:43  asuraparaju

	* libdirac_byteio/: dirac_byte_stream.cpp,
	  endofsequence_byteio.cpp, endofsequence_byteio.h: Fix the bug
	  which reported "total bits for sequence" in verbose mode to be
	  less than the actual the size (in bits) of the bitstream file
	  written to disk.  This was because the number of bytes in the end
	  of sequence header was not being included in the total bits for
	  the sequence.

2007-03-29 17:07  asuraparaju

	* configure.ac: Include VisualStudio in list of directories to
	  generate Makefile in.

2007-03-29 15:08  asuraparaju

	* decoder/Makefile.am, encoder/Makefile.am: Fix for bug# 588191.
	  Include libdirac_byteio.a in the libraries to be linked with for
	  encoder and decoder utilities.

2007-03-28 15:33  asuraparaju

2007-03-28 12:05  tjdwave

	* libdirac_encoder/rate_control.cpp: Temporarily disabled buffer
	  model conformance.

2007-03-27 17:31  asuraparaju

	*
	  win32/VS2003/DiracEncoder/libdirac_encoder/libdirac_encoder.vcproj:
	  Included rate_control.cpp and rate_control.h in sources list.

2007-03-27 17:29  asuraparaju

	* libdirac_common/: band_codec.cpp, common.cpp, common.h: Fix
	  compile warnings and errors in MS Windows build. The max numbe of
	  quantisers supported is now 120. Modified code to calculate
	  quantisation factor to be compliant with latest version of spec.

2007-03-27 17:26  asuraparaju

	* libdirac_byteio/parseunit_byteio.cpp: [Spec Compliance] The next
	  and previous parse unit offsets in the bytestream are now 4 bytes
	  each.

2007-03-27 16:20  tjdwave

	* libdirac_common/common.h, libdirac_encoder/rate_control.cpp,
	  libdirac_encoder/rate_control.h,
	  libdirac_encoder/seq_compress.cpp: Major refactor of rate control
	  algorithm. The original algorithm aimed for constant bit rate
	  over a single GOP. This tended to be unstable when content
	  changed and could cause quality to degrade significantly at the
	  end of GOPs in order to attempt to correct for high bit rate at
	  the beginning.

	  The algorithm has been revised so that a target buffer occupancy
	  is aimed for, with the target bit rate set as equal to the mean
	  bit rate plus an adjustment factor to steer back to target. Bit
	  rate is computed for a subgroup (PBB or IBB) in a very similar
	  way, but on a rolling basis rather than a target for a single
	  GOP.

	  For the moment, a buffer size of 4xbit rate has been selected.
	  Fixed buffer sizes may be implemented when levels are specified.

	  Buffer overflows (too little bit rate - this is a _decoder_
	  buffer model) or underflows (too much bit rate) are indicated by
	  warnings in verbose mode.  The buffer occupancy is then limited,
	  so that these events are not corrected for at present.

2007-03-26 16:28  tjdwave

	* libdirac_encoder/dirac_encoder.cpp: Fixed computation of GOP
	  statistics to maintain coded order. GOP is counted as up to just
	  before the next scheduled access point (intra frame).

2007-03-26 12:20  asuraparaju

	* libdirac_common/mot_comp.cpp: Weights are now being correctly set
	  for edge blocks.  Fixed bug where data outside the picture in the
	  block in the bottom right corner was not being ignored.

2007-03-26 11:24  davidf_

	* libdirac_encoder/quant_chooser.cpp: Stop quantizing DC subband at
	  all, otherwise chroma error is appearing.  Also includes fix from
	  thomasd to look at the whole of the DC subband instead of
	  ignoring the first (most important value)

2007-03-23 15:32  asuraparaju

	* libdirac_common/pic_io.cpp, tests/Makefile.am,
	  tests/colourbars.at, tests/samples.at,
	  util/instrumentation/instrmain.cpp: Changes to keep test scripts
	  and instrumentation utility in sync with the altered command
	  lines for the encoder, decoder.

2007-03-22 18:27  davidf_

	* ChangeLog, README, decoder/decmain.cpp, encoder/encmain.cpp:
	  Altered command line file handling.  a) now support taking input
	  from stdin (input specified as '-' or '/dev/stdin').	b) removed
	  strange filename extension stripping/appending for primary input
	  and output files (locally decoded video and instrumentation are
	  outputfilename.{local-dec.yuv,imt}.

2007-03-22 14:48  davidf_

	* libdirac_common/common.h: Temporary fix to stop RateControll
	  setting silly QF

2007-03-22 14:45  davidf_

	* README: Added instructions on using CBR encoding.

2007-03-21 11:05  tjdwave

	  libdirac_common/common.h, libdirac_encoder/Makefile.am,
	  libdirac_encoder/dirac_encoder.cpp,
	  libdirac_encoder/dirac_encoder.h,
	  libdirac_encoder/quality_monitor.cpp,
	  libdirac_encoder/seq_compress.cpp,
	  libdirac_encoder/seq_compress.h: Added support for CBR encoding.
	  This equalises bitrate over a GOP (I frame  to  I frame). It does
	  not enforce bit rate, nor does it operate according to a buffer
	  model.

	  To apply CBR coding, add -targetrate N, where N is the target bit
	  rate in Kb/s.

	  Precedence: 1) if a quality factor is also set with -qf Q, then
	  the value of Q is used as the initial value for the system, but
	  CBR is still applied.  2) if -lossless is also set, then lossless
	  coding is applied and CBR constraints are ignored.

	  in both modes of compiling.

2007-03-19 16:16  asuraparaju

	* libdirac_common/: frame.cpp, upconvert_mmx.cpp: Fixed upconvert
	  (MMX version) to clip after each filtering operation as per spec
	  0.10.4 and to be in sync with the non-MMX version

2007-03-19 15:19  davidf_

	* libdirac_common/wavelet_utils.cpp: Useful comment thats been
	  sitting in my local copy for ages

2007-03-01 15:32  tjdwave

	* libdirac_decoder/comp_decompress.cpp: Removed reference to
	  InitContexts.

2007-03-01 10:38  tjdwave

	* doc/latex_spec/: arith.tex, motion-dec.tex, state-macros.tex,
	  wlt-dec.tex: Incorporated changes to arithmetic coding. This is a
	  quick hack that may not compile yet. TBC.

2007-03-01 09:24  tjdwave

	* libdirac_common/: arith_codec.h, band_codec.cpp, band_codec.h,
	  mv_codec.cpp, mv_codec.h: Changed arithmetic coding again
	  slighly. Restored count initialisation to (1,1) and reordered
	  probability/count rescaling parts to get a little more compact
	  code and greater speed. Tidied band codec and mv codec stuff.

2007-02-28 16:22  tjdwave

	* libdirac_common/: arith_codec.cpp, arith_codec.h, band_codec.cpp,
	  band_codec.h, mv_codec.cpp: Modified arithmetic coding for speed,
	  incorporating periodic calculation of probabilities. Also removed
	  periodic context rescaling, which wasn't really helping
	  compression performance, and added to complexity.

2007-02-20 14:06  tjdwave

	* libdirac_common/: arith_codec.cpp, arith_codec.h: Code tidy,
	  removing a preponderence of inline functions. Also improved
	  renormalisation.

2007-02-20 09:55  tjdwave

	* libdirac_common/: arith_codec.cpp, arith_codec.h: Modified
	  renormalisation condition and simplified renormalisation process.
	  Renormalisation is now only invoked if the interval is <=1/4 of
	  the range.  This means that either the most significant bits of
	  low and high are the same, or we have low=0x01... and high =
	  0x10.. i.e. a classic straddle.  This reduces the 3-way branch
	  condition to a 2-way one. It also means that we can eliminate use
	  of the high variable altogether and just use low and range.

2007-02-20 09:39  tjdwave

	* libdirac_common/: arith_codec.cpp, arith_codec.h: Changed
	  structure of renormalisation loop to enable optimisation.

2007-02-20 09:24  tjdwave

	* libdirac_common/: arith_codec.h, arith_codec.cpp: Now updating
	  range variable on the fly rather than calculating from low and
	  high.

2007-02-20 09:21  tjdwave

	* libdirac_common/: arith_codec.cpp, arith_codec.h: Refacactored
	  arithmetic coding so that renormalisation is only performed if
	  the interval size is <=1/2 (represented by 0x8000 in 16 bits).
	  This condition may be further restricted in future, and other
	  changes and optimisations will follow. This change makes
	  coding/decoding faster and allows for the high code to be
	  eliminated. Watch this space.

2007-02-07 12:03  davidf_

	* libdirac_common/: frame.cpp, upconvert.cpp, upconvert.h: Fixed
	  upconvert (non MMX) to:   - perform unbiased rounding as per spec
	  0.10.4   - clip after each filtering operation as per spec 0.10.4

2007-02-01 15:28  tjdwave

	* libdirac_common/common.cpp: D'oh! Correct commit.

2007-02-01 15:15  tjdwave

	  factors so that intermediate values don't run out of precision.

2007-01-23 14:18  davidf_

	* libdirac_common/band_codec.cpp: Fixed nhood_zero selection as per
	  spec-0.10.4

2007-01-22 15:53  tjdwave

	* doc/latex_spec/mc.tex: Reorganised the text concerning chroma
	  scaling for clarity. Chroma scaling for global motion vectors is
	  now achieved by scaling the generated luma field rather than
	  scaling the generating matrix and vectors. This will change the
	  bitstream.

2007-01-22 14:58  tjdwave

	* doc/latex_spec/: bs-spec.tex, mc.tex,
	  ref-default-videoparams.tex, state-macros.tex, wlt-dec.tex: Some

2007-01-22 14:20  tjdwave

2007-01-22 12:22  tjdwave

	* libdirac_common/wavelet_utils.cpp: Fixed subband order so that it

2007-01-11 09:42  tjdwave

	* doc/latex_spec/: bs-spec.tex, picture-dec.tex, state-macros.tex:
	  Changed spec so that the size of the reference picture buffer is
	  determined from the level and profile information rather than
	  fixed as 5 pictures.

	* doc/latex_spec/mc.tex: Fixed typos.

2007-01-03 08:32  tjdwave

	* doc/latex_spec/idwt.tex: Changed the specification of how wavelet
	  filters are adapted at the array edges to match what the Dirac
	  code does, which is to use edge extension of the even and odd
	  coefficients separately.

2006-12-13 09:10  tjdwave

	* libdirac_encoder/frame_compress.cpp: Fixed bug with unitialised
	  cut flag. Changed intra insertion criterion so that a frame is
	  made intra if just a third of blocks are intra - this is a better
	  bit rate trade-off.

2006-12-05 14:36  tjdwave

	* libdirac_common/frame_buffer.cpp, libdirac_common/frame_buffer.h,
	  libdirac_decoder/frame_decompress.cpp,
	  libdirac_decoder/seq_decompress.cpp,
	  libdirac_encoder/seq_compress.cpp: Fixed memory leak bug, which
	  resulted from the encoder not signalling the discarded reference
	  frames correctly. The reference management and FrameBuffer class
	  code still need some work to rationalise.

	  The decoder still does not support the spec requirement for
	  discarding old reference frames if the reference frame buffer
	  gets too big. This would prevent memory leaks (at the risk of
	  incorrect decoding) if the encoder were to signal reference
	  discarding incorrectly in this manner.

2006-12-04 12:00  davidf_

	* doc/faq.html: Fixed markup faults spotted by Peter Shelswell:  -
	  Fixed errant <h> tag	- Added <?xml ?> identifier

	  state-macros.tex, stream-access.tex, wlt-dec.tex: Nearly complete
	  version of low-delay syntax, at least for intra frames.  Data
	  encoding section revised to incorporate "bounded" inputs for vlcs
	  as well as for arithmetic encoding, unifying the description.

	  More detail on buffering and profiles/levels.

	  denoised values. Denoiser uses a centre-weighted median filter.
	  Also applied Johannes Reinhardt's cosmetic patch to the encoder
	  to tidy it up.

2006-11-13 14:20  tjdwave

	* doc/latex_spec/wlt-dec.tex: Changed inverse quantisation offset

	  libdirac_decoder/comp_decompress.cpp,
	  libdirac_encoder/comp_compress.cpp,
	  libdirac_encoder/quant_chooser.cpp: Changed quantiser offsets to
	  be different for Intra and Inter frames, as per the latest draft
	  of the spec. Having an offset of 0.5*quantiser for intra frames
	  improves performance at high rate, especially iterated coding
	  with Dirac Pro apps.

	* doc/latex_spec/: arith-encoder.tex, arith.tex,
	  layout-fullsize.tex, low-delay.tex, mc.tex, motion-dec.tex,
	  profilelevel.tex, spec-conventions.tex, spec-structure.tex,
	  wlt-dec.tex: Added more text on the low-delay syntax and decoded
	  picture buffer model.  Clarified arithmetic decoding process and
	  conventions.

	  libdirac_encoder/quant_chooser.cpp,
	  libdirac_motionest/motion_estimate.cpp,
	  libdirac_motionest/pixel_match.cpp: Overall improvements to
	  encoding framework to improve quality for difficult pictures and
	  at low bit rates. Changes to the RDO parameters are experimental
	  and they may change again.

	  - Added test for whether a frame is a B frame or not - Identified
	  Layer 1 frames with P frames and Layer 2 with B frames, rather
	  than with Inter Ref and Inter Non-ref respectively. This is more
	  efficient with the new GOP structure - Modified RDO framework to
	  provide correction where there has been ME failure i.e. lots of
	  Intra blocks - Slightly increased ME search areas - Corrected the
	  frame type parameter for the final B frame in a sequence -
	  Changed confusing terminology for costs/errors in quantisation
	  factor selection - Added overall PSNR stats for a sequence for
	  performance comparisons

2006-10-30 15:17  tjdwave

	* doc/latex_spec/: arith.tex, dataenc.tex, motion-dec.tex,
	  wlt-dec.tex: Fixed bug in specification of inverse quantisation.
	  Changed default arithmetic decoding padding value to 1 from 0, so
	  after reading in LENGTH bytes, a value of 1 is used from that
	  point. This should support early termination i.e.  encode only
	  the first few values in a subband and then the decoder will
	  correctly decode the remainder as 0, but this is as yet untested.

2006-10-30 14:57  tjdwave

	* libdirac_common/arith_codec.cpp: Fixed bug so that the decoder
	  can now append any data to the end of the arithmetically encoded
	  block and still decode correctly. Default padding data is all 1s
	  - this should make a null or terminated subband decode with
	  zeroes.

2006-10-30 13:42  tjdwave

	* libdirac_common/band_codec.cpp, libdirac_common/motion.cpp,
	  libdirac_common/motion.h, libdirac_common/mv_codec.cpp,
	  libdirac_decoder/comp_decompress.cpp: Fixed definitions of
	  mean/median so that unbiased mean values are used.  Likewise
	  changed the prediction for DC values to take account of the fact
	  that they may be negative. These changes change the bitstream.

2006-10-30 13:38  tjdwave

	* doc/latex_spec/: motion-dec.tex, spec-conventions.tex,
	  wlt-dec.tex: Changed specification of division so that it agrees
	  with C/C++ standards.  Traced through these changes to
	  specification of split mode, block dc value and intra dc band
	  prediction.

2006-10-26 16:22  tjdwave

	* libdirac_encoder/dirac_encoder.cpp: Moved to using cout instead
	  of cerr for reporting.

2006-10-26 16:07  tjdwave

	* libdirac_common/common.cpp, libdirac_common/common.h,

	  libdirac_decoder/seq_decompress.cpp,
	  libdirac_encoder/frame_compress.cpp,
	  libdirac_encoder/seq_compress.cpp: Made  operation of retired
	  picture list comply with specification: only reference pictures
	  are signalled to be retired and non-reference pictures are
	  retired by the decoder once they are displayed.

	  Clarified frame type parameters so as to be sure they always
	  agree. This will need further refactoring.

	  Reference frames are now cleaned from the buffer _after_ being
	  the current frame has been decoded, as per the spec. This allows
	  slightly more flexible GOP structures.

2006-10-25 14:01  tjdwave

	* libdirac_common/common.cpp: Fixed bug with wrong quantiser offset
	  being used: now complies with spec again.

	  together with profile and level text. Work in progress!

2006-10-19 16:01  tjdwave

	* doc/latex_spec/picture-dec.tex: Changed order of reference buffer
	  management so that a reference picture is not removed until after
	  the current picture has been decoded,

2006-10-19 14:53  tjdwave

	* libdirac_common/band_codec.cpp: Put in Dave Schleef's patch for

	* encoder/encmain.cpp, libdirac_common/common.cpp,
	  libdirac_common/dirac_types.h,

	  the video format defaults.

2006-10-09 16:24  tjdwave

	* libdirac_common/wavelet_utils_mmx.cpp: Renamed functions with

2006-09-12 09:58  tjdwave

	* doc/latex_spec/vidsys.tex: Slightly revised - to be merged with
	  source parameters presets.

2006-09-12 09:56  tjdwave

	* doc/latex_spec/: idwt.tex, mc.tex, picture-dec.tex: Finished
	  first draft of overall picture decoding process. Added stuff on
	  global motion compensation (_probably_ works now).

2006-09-12 09:54  tjdwave

	* doc/latex_spec/: bs-spec.tex, motion-dec.tex, wlt-dec.tex:

2006-09-12 09:48  tjdwave

	* doc/latex_spec/spec-conventions.tex: Updated/added material on
	  the way the pseudocode works and the mathematical notation. This
	  section still needs work and reordering.

2006-09-12 09:45  tjdwave

	  libdirac_motionest/me_mode_decn.cpp,
	  libdirac_motionest/me_mode_decn.h: Removed the Macroblock
	  "Common" mode. This means that each prediction unit within a
	  macroblock will have to code a mode. Motion data coding has also
	  been changed so that instead of coding all the prediction modes
	  first and then all the motion data, prediction modes are included
	  in the motion data as per the spec.

	  An updated version of the latex spec in which the Common mode is
	  omitted is in preparation and will be committed in the next
	  couple of weeks.

2006-07-19 12:29  tjdwave

	* doc/latex_spec/prep-idwt-process.tex: Added initialisation of the

	  arith-decoder-sint.tex, arith-decoder.tex, arith-engine.tex,
	  arith-init.tex, arith-intro.tex, arith-update.tex, arith.tex:
	  Refactored to take account of exp-Golomb binarisation and the use
	  of global context indices being passed to arithmetic decoding
	  operations.

2006-07-18 11:36  tjdwave

	* libdirac_common/: band_codec.cpp, band_codec.h: Changed nhood sum
	  calculation so that it only takes account of whether the

	  figs/sequence.eps, figs/superblock-16pu.eps,
	  figs/superblock-1pu.eps, figs/superblock-4pu.eps: Updated and
	  refactored data access and coefficient decoding sections.  Spec
	  should be up to date and accurate for coefficient decoding, but
	  fine-tuning and checking is required. Diagrams also needed.

	  Major change is in the way arithmetic decoding operations are
	  called. Just specify sets of contexts to be used for follow bits,
	  data bits and the sign by passing indices into the state
	  variable, which maintains the contexts.

	  This simplifies the code in the stream syntax, avoiding local
	  copies etc.  Explanation will be required for the context
	  indices. The arithmetic decoding section needs updating to
	  reflect this change and use of interleaved exp- Golomb coding.

2006-07-07 08:56  tjdwave

	* doc/latex_spec/layout-fullsize.tex: Added temporary environment
	  pseudo* for documenting _part_ of a function's pseudocode (no
	  function header).  Fixed bug where \bsRET reduces indent by 1 -
	  this broke indentation when there were a number of returns in a
	  function.

2006-07-06 12:29  tjdwave

	* libdirac_common/: band_codec.cpp, band_codec.h: Changed coding of
	  codeblock quantiser indices to be differential codeblock to
	  codeblock, as per Tim's stream syntax, rather than differential
	  with respect to the subband quantiser index.

	  N.B. this now does not agree with version 0.9.

	  align with arithmetic decoding section.

2006-07-03 10:08  tjdwave

	* doc/latex_spec/: layout-fullsize.tex, state-macros.tex: Adding

	* libdirac_common/: arith_codec.h, mv_codec.cpp, mv_codec.h: Added
	  En/DecodeUInt and En/DecodeSInt functions to the arithmetic codec
	  class. These functions read and write signed and unsigned
	  integers in a unified way. They are used to replace the acres of
	  duplicated code in mv_codec.cpp. This change also had the happy
	  side effect of removing the need for a whole slew of chooseXXX
	  functions used for selecting the arithmetic coding context.

2006-06-12 16:24  stuart_hc

	* libdirac_decoder/frame_decompress.cpp: whitespace cleanup

	  libdirac_decoder/frame_decompress.cpp,
	  libdirac_encoder/comp_compress.cpp,
	  libdirac_encoder/frame_compress.cpp: Use enumerated values for
	  number of motion vector contexts and coefficient contexts instead
	  of hardcoded constants. This helps in not having to change

	  restructure of Input/Output classes in Dirac internals. New
	  directory, libdirac_byteio contains classes to input from/output
	  to a Dirac bistream.

	  Dirac external API (both encoder and decoder) has changed. So the
	  patches for MPlayer, FFmpeg, and the Dirac Directshow filter will
	  no longer work with the CVS source. The external API is likely to
	  change over the next few weeks.  Updated versions of the patches
	  and Direcshow filter will be available with the next release of
	  Dirac.

	  NOTE: the bytestream has changed to largely conform to the latest
	  Dirac spec.  More work needs to be done to conform fully to the
	  Dirac definition document. So expect the CVS source and resulting
	  bitstream to change frequently over the next few weeks.

	* libdirac_common/arith_codec.h, libdirac_common/band_codec.cpp,
	  libdirac_common/band_codec.h, libdirac_common/common.h,

	  libdirac_decoder/frame_decompress.cpp,
	  libdirac_encoder/comp_compress.cpp,
	  libdirac_encoder/frame_compress.cpp: Changing binarisation for
	  arithmetic coding, and associated contexts.  The specification
	  will be modified accordingly.

	  Binarisation for the magnitude values of wavelet coefficients,
	  motion vector prediction residues and DC values has been changed
	  from unary to interleaved exp-Golomb so that the number of
	  symbols to be decoded in order to reconstruct a coefficient is
	  reduced. Exp-Golomb binarisation takes a number N>=0 and codes it
	  via the binary representation of N+1, 1bbbbbb. If there are K
	  bits following the leading 1, the representation is K zeroes
	  followed by the binary representation:

	  00...01bbbbb Interleaved exp-Golomb is the same, except that the
	  K lsbs are interleaved with the zeroes: 0b0b	 0b1 so that a
	  single decoding loop can be used. The zeroes here act as "follow
	  bits" indicating that another bit is to be sent, with 1 as the
	  terminator.

	  Contexts for coding these symbols are selected for the follow
	  bits and other bits ("information bits") separately. Compression
	  performance is hardly affected, nor is speed performance in
	  software, but hardware performance is greatly facilitated.

2006-04-12 16:06  tjdwave

	* libdirac_common/arith_codec.h: Changed while loops for decoding
	  and encoding into fixed-size for-loops with break conditions.
	  Although ugly, this provides safer code as loops will terminate
	  if there's an error.

2006-04-11 12:23  asuraparaju

	* unit_tests/motion_comp_test.cpp: Set number of references in
	  MvData constructor to fix compilation errors.

2006-04-10 11:13  tjdwave

	* libdirac_common/band_codec.cpp: Changed lookup table-based
	  division to a straight division. This is slightly slower, but
	  will scale to higher levels of wavelet decomposition.  Also
	  eliminates bug with occasional wrap-around for lossless coding on
	  some pictures. Making abs_val 64 bits would also work but could
	  be equally slow on 32 bit architectures.

2006-03-20 12:54  asuraparaju

	* encoder/encmain.cpp, libdirac_encoder/dirac_encoder.cpp: Fixed
	  bug in writing instrumentation data to output which always
	  assumed that data for two references were available.

	  libdirac_motionest/me_mode_decn.cpp,
	  libdirac_motionest/pixel_match.cpp,
	  util/instrumentation/process_sequence.cpp: Changed block mode
	  coding so that residues for reference 2 are not generated when we
	  are only using one reference.  THIS CHANGES THE BYTESTREAM This
	  reduces the bit rate by a few bits, but the reason for doing it
	  is becuase it makes the codec more logical.  Also modified
	  BlockModePrediction so that it doesn't do a prediction for
	  reference 2 when we are only using one reference.  Removed some
	  unnecessary memory allocation in MvData constructor.	Removed a
	  few warning messages and tidied up a bit.

2006-03-01 18:19  asuraparaju

	* libdirac_common/: arith_codec.cpp, arith_codec.h: Rationalised
	  types used i.e. replaced all code_t, calc_t etc with unsigned
	  int. Simplified the code by removing one addition and shift from
	  DecodeSymbol.

2006-02-28 15:53  asuraparaju

	* libdirac_common/arith_codec.cpp: Fixed g++ warning when compiled
	  in debug mode

	* libdirac_common/Makefile.am,
	  win32/VS2003/libdirac_common/libdirac_common.vcproj: Added
	  arith_codec.cpp to list of .cpp files

2006-02-28 15:25  asuraparaju

	* libdirac_common/: arith_codec.cpp, arith_codec.h: Refactored code
	  to make implementation easier to understand. The code restructure
	  modified the bitstream but older version of arith_codec can
	  decode this new version and vice-versa.

2006-02-21 13:32  tjdwave

	* libdirac_common/arith_codec.h: Modified arithmetic coding engine
	  for speed and spec conformance.  1. Changed context statistics so
	  that maximum weight is 256 2. Changed look-up table so that
	  inverse of weight is calculated to 16 instead of 31 bits.  3.
	  Changed scaled count of zero m_prob0 so that it's 16 bits instead
	  of 10

	  Changes 1-3 mean that m_prob0 can be worked out using only 16 bit
	  multiplies and no bitshift. This is more hardware friendly.

	  4. Modified do .. while loop for encoding and decoding so that a
	  more efficient test for MSB equality can be used, resulting in a
	  speed-up 5. Changed the order of decoding so that bits are
	  shifted in first and then the symbol is determined. This reduces
	  unnecessary bit inputs and moves to a 'lazy' input mode 6.
	  Changed the statistics update function so that m_prob0 is
	  calculated for every update rather than every other. This speeds
	  up the code and gives better compression performance.

2006-02-15 14:27  asuraparaju

	* tests/samples.at: Included  block variables so that tests can be
	  run for different block sizes. Note that the block sizes must be
	  changed manually before running the tests.

2006-02-15 14:26  asuraparaju

	* libdirac_motionest/: me_utils.cpp, me_utils_mmx.cpp,
	  pixel_match.cpp: Padding related changes. Since there may no
	  longer be an integer number of whole macroblocks and blocks in a
	  paddied picture, made changes to ensure that we do not fall off
	  the boundaries of the padded pictured during motion estimation.
	  WARNING : This changes the bitstream

	* libdirac_common/: mot_comp.cpp, mot_comp.h, mot_comp_mmx.cpp,
	  mot_comp_mmx.h: A linear function is used to calculate the OBMC
	  weights instead of a raised cosine function to make it compliant
	  with spec. Also motion compensation is performed only on true
	  picture dimensions and not padded picture dimensions, WARNING :
	  This changes the bitstream

	  libdirac_encoder/seq_compress.cpp, unit_tests/frames_test.cpp,
	  unit_tests/motion_comp_test.cpp: Currently a frame is padded so
	  that it has an integer number of whole macro blocks and is also a
	  multiple of 2^(wavelet transform depth). This has changed in the
	  Dirac specification where a frame is padded so that its
	  dimensions are a multiple of 2^(wavelet transform depth) only.
	  Also the luma and the chroma components can be padded
	  differently. E.g. the luma dimensions may be a perfect multiple
	  of 2^(wavelet transform depth) so the luma component is not
	  padded but the chroma component may need to be padded depending
	  on the chroma format of the input.  To take care of this,
	  FrameParams class has been modified to accept both padded chroma
	  and padded luma dimensions.

	  WARNING! This modifies the bitstream.

2006-02-14 12:48  tjdwave

	* libdirac_common/arith_codec.h: Changed count rescaling so that it
	  occurs every time a bit is encoded/decoded.  This is to make
	  compliant with spec, and also because doing it every other bit
	  was giving no speed advantage.

	  WARNING! This changes the bitstream.

2006-02-10 09:49  tjdwave

	* libdirac_common/common.cpp: Modified calculation of quantisation,
	  inverse quantisation and offset values so as to conform to
	  specification.  WARNING: this modifies the bitstream.

2006-02-09 13:58  tjdwave

	* libdirac_common/: motion.h, mv_codec.cpp: Removed the function
	  for computing a mean of a vector of ints. Instead all means are
	  of unsigned int values, and are calculated using unbiased
	  arithmetic ie with an offset of N/2 for N values to ensure even
	  rounding. This changes the mean used for predicting DC values in
	  motion vector coding. As a result, the bitstream is also changed.

2006-01-06 15:56  tjdwave

	* libdirac_common/mv_codec.cpp: Changed refresh so that statistics
	  are refreshed after m_reset_num macroblocks as intended, rather
	  than m_reset_num+1.  WARNING! This changes the bitstream.

2006-01-06 15:22  asuraparaju

	  instrumentation tests.

2005-12-01 14:27  asuraparaju

	* encoder/encmain.cpp: Generation of Diagnostics data and locally
	  decoded output is now disabled by default. To enable this use the
	  commandline option -local.

2005-12-01 14:26  asuraparaju

	* libdirac_common/upconvert_mmx.cpp: Mods to make
	  Upconverter::DoUpconverter function more efficient

2005-12-01 14:25  asuraparaju

	* libdirac_common/wavelet_utils.h: New function
	  VHFilter5_3::HorizSynth which is used only when MMX opts are
	  enabled. This function is used to interleave horizontal synthesis
	  with vertical synthesis to make the wavelet syntheis function
	  slightly more efficient.

2005-12-01 14:22  asuraparaju

	* libdirac_common/: band_codec.cpp, band_codec.h: New function
	  ClearBlock to set all values in block to 0 more efficiently.
	  Applied BandCodec optimisation part of patch 1303281 which make
	  DecodeVal function more efficient.

2005-12-01 14:12  asuraparaju

	* libdirac_common/wavelet_utils_mmx.cpp: Minor mods to optimise
	  VHFilter5_3::Split further.

2005-12-01 14:10  asuraparaju

	* libdirac_common/mot_comp_mmx.cpp: Minor changes to ensure that
	  uninitialised memory reads do not cause crashes when compiled
	  using MS VC++. Note that the data read from unitialised memory is
	  not being used but still causes problems on some platforms.

2005-12-01 14:06  asuraparaju

	* libdirac_common/mot_comp.cpp: Using calculated values of blocks
	  per macro block row and blocks per sub-block row instead of
	  hardcoded values.

2005-12-01 14:02  asuraparaju

	* util/encoder_gui/: README, diracdata.h, diracgui.cpp, diracgui.h,
	  encodebox.cpp, encoder_gui.pro, filesbox.cpp, repthread.cpp,
	  tables.h: Included option in GUI to disable the creation of
	  diagnostics data file and locally decoded output. dirac_encoder
	  need no longer be in the current working directory but in any
	  directory in the PATH variable.

2005-11-15 15:35  asuraparaju

	* libdirac_common/arith_codec.h: Minor cosmetic difference as to
	  how CODE_MSB and CODE_2ND_MSB are initialised to make their usage
	  more obvious.

2005-11-15 15:33  asuraparaju

	* doc/Makefile.am: Fix problem with install target

2005-11-08 11:45  asuraparaju

	* libdirac_common/band_codec.cpp: Minor changes in DoWorkCode,
	  DoWorkDecode and DecodeCoeffBlock functions in the way 2-D arrays
	  are accessed which resulted in a slight decoding speed
	  improvement.

2005-11-08 11:43  asuraparaju

	* libdirac_common/upconvert_mmx.cpp: Minor changes to DoUpConverter
	  routine to give slight improvement in uoconversion speed.

2005-11-08 11:41  asuraparaju

	* libdirac_common/arrays.h: In Resize function in OneDArray class,
	  dealloc and realloc data only if the new and old array sizes are
	  different.

2005-11-08 11:40  asuraparaju

	* libdirac_common/: wavelet_utils.cpp, wavelet_utils_mmx.cpp:
	  Optimised WaveletTransform::VHFilter5_3::Split using MMX
	  instructions. Minor mods to WaveletTransform::VHFilter5_3::Synth
	  function improve speed slightly.

2005-11-08 11:37  asuraparaju

	* libdirac_motionest/Makefile.am,
	  libdirac_motionest/downconvert.cpp,
	  libdirac_motionest/downconvert_mmx.cpp,
	  win32/VS2003/libdirac_motionest/libdirac_motionest.vcproj:
	  Optimised DoDownConverter routine using MMX instructions

2005-11-08 11:34  asuraparaju

	* libdirac_common/: mot_comp.cpp, mot_comp.h, mot_comp_mmx.cpp:
	  Modified motion compensation so that it take Macro-Block
	  splitting mode into consideration when compensating a row of
	  blocks. Depending on the macroblock split mode, 1,2 or 4 blocks
	  of reference data are used to calculate the motion compensated
	  data. This sped up the default quarter pixel block motion
	  compensation routine by an average of 20-23% for a 2Mbps Dirac
	  bitstream.

2005-11-08 11:26  asuraparaju

	* libdirac_common/: frame.cpp, frame.h, frame_buffer.cpp,
	  frame_buffer.h: Changes to FrameBuffer handling. Deleting old
	  frames and allocating new frames is quite expensive. So instead
	  of deleting frames no longer required in the frame buffer, they
	  are flagged "not in use". So the next time a new reference frame
	  has to be inserted in the Frame buffer, the first frame "not in
	  use" is used to store the new frame. An overall improvement of
	  6-7 percent in decoding speed for a 2Mbps bitstream resulted.

2005-10-17 12:06  asuraparaju

	* libdirac_encoder/dirac_encoder.cpp: Fixed bug #1328565. Now
	  ensuring that all locally decoded frames are available for
	  output.

2005-10-11 14:02  tjdwave

	* libdirac_common/arith_codec.h: Incorporated Steve Bearcroft's
	  speed-up patch, with some minor typographical changes for
	  clarity.

2005-10-11 10:00  tjdwave

	* libdirac_motionest/block_match.cpp: Added patch 1309571 which
	  fixes the quality degradation introduced in the motion estimation
	  speed-ups.

2005-10-07 11:17  asuraparaju

	* libdirac_motionest/: me_utils.cpp, me_utils_mmx.cpp,
	  me_utils_mmx.h: Applied MMX optimisations to modified ME
	  routines. This is an initial version that improves Motion
	  Estimation speed by 30% resulting in a 20% improvement in
	  encoding speed overall. This is work in progress.

2005-09-27 14:44  dirac_dev

	* libdirac_encoder/dirac_encoder.h: Replaced boolean with int.
	  C-compilers (eg. ffmpeg) complain about C++ constructs.

2005-09-27 14:08  tjdwave

	* libdirac_encoder/quality_monitor.cpp: Set the motion estimation
	  factor to compensate for the default search precision being at
	  1/4 pel (as this is the default precision) rather than 1/8th pel.

2005-09-27 14:07  tjdwave

	* libdirac_motionest/: motion_estimate.cpp, motion_estimate.h:
	  Removed cut detection, which is now in the FrameCompressor class.
	  Removed the kludge which scaled the motion vector precisions. All
	  motion estimation is now at the selected precision.

2005-09-27 14:01  tjdwave

	* libdirac_motionest/: me_mode_decn.cpp, me_mode_decn.h: Use
	  specific matching classes for different pixel accuracies. Reduced
	  search ranges for increased speed.

2005-09-27 13:59  tjdwave

	* libdirac_motionest/me_subpel.cpp: Removed calculation of lambda
	  map. Simplified class by using the specific subpixel refinement
	  matching function.

2005-09-27 13:55  tjdwave

	* libdirac_motionest/: pixel_match.cpp, pixel_match.h: Search
	  ranges restricted to improve motion estimation speed.

2005-09-27 13:52  tjdwave

	* libdirac_motionest/: block_match.cpp, block_match.h: Refactored
	  the BlockMatcher class. There are now three functions for finding
	  a best match - finding the pixel-accurate best match, refining
	  this to sub-pixel accuracy, and also finding a best match from a
	  list at sub-pixel level.  These matching functions contain
	  shortcuts to speed up matching as follows.

	  FindBestMatchPel: - The predictors are each searched first, and
	  if their SAD values are small then the search ends.  - bailout
	  functions are used for calculating matching costs for the
	  remaining candidates

	  RefineMatchSubpel: - The predictor from neighbouring (previously
	  refined) vectors is tested first. If there's a small SAD, then
	  the search ends - Pixel-accurate vectors are refined to half-pel
	  vectors by searching the 4 closest half-pel positions (shown as
	  X) first:  X XOX  X

	  If one of these is better than the pixel-accurate value, then the
	  two nearest values in the immediate neighbourhood of the
	  pixel-accurate value are also searched, eg the Y values below:

	  YXY XOX  X

	  This two-stage procedure is followed again in refining to
	  quarter- and eighth-pel.  - At each stage of refinement, if we're
	  10% worse than the value derived for the predictor, we end the
	  search.

	  FindBestMatchSubpel: - bailout functions are used

2005-09-27 13:40  tjdwave

	* libdirac_motionest/: me_utils.cpp, me_utils.h: Reorganised
	  classes for doing SAD calculations at pixel and sub-pixel
	  accuracy. Distinct classes for half-, quarter- and eighth-pixel
	  matching have been created. These are present also in 'bailout'
	  form so that you can leave the calculation as soon as you know
	  that you're not going to beat the best match so far.	These mods
	  support speeding up motion estimation, and hence the encoder
	  generally.

2005-09-27 12:25  asuraparaju

	* libdirac_encoder/dirac_encoder.cpp: Fixed bug# 1291478. Now
	  ensuring that dirac_encoder_output returns ENC_STATE_BUFFER when
	  data is not loaded into the encoder.

2005-09-27 12:21  asuraparaju

	*
	  doc/documentation/code/programmers_guide/decoder_api_functions.htm:
	  Bug fix: 1291481. Corrected return value in dirac_parse function
	  prototype.

2005-09-27 10:21  tjdwave

	* libdirac_encoder/seq_compress.cpp: The quality measurement model
	  can only be calculated correctly if reconstructed compressed
	  video is available, which isn't the case if we're not doing local
	  decoding. In this case, calculating and outputting these values
	  is disabled.

2005-09-27 10:16  tjdwave

	* libdirac_encoder/: frame_compress.cpp, frame_compress.h: Moved
	  the analysis of whether or not we have a cut into FrameCompressor
	  class and out of motion estimation classes.

	  Also, only do motion compensation on L2 frames if local decoding
	  is required.	This is because, by definition, L2 frames can't be
	  references and so can be left in a partially reconstructed state
	  if local decoding isn't required, which improves encoding speed.

2005-09-27 10:12  tjdwave

	* libdirac_encoder/dirac_encoder.cpp: Added support for local
	  decoding flag, so that local decoding can be avoided for speed.

2005-09-27 10:09  tjdwave

	* libdirac_encoder/comp_compress.cpp: Removed commented-out code.

2005-09-27 10:09  tjdwave

	* libdirac_encoder/comp_compress.cpp: Inverse wavelet transform is
	  now only done for L2 frames if local decoding is required. This
	  is because L2 frames are (by definition) not used for reference
	  and can be left in a partially reconstructed state if local
	  decoding isn't needed.

2005-09-27 09:54  tjdwave

	* libdirac_common/mot_comp.cpp: Introduced unbiased rounding into
	  calculation of weighting matrices. This allows the subsequent
	  rationalisation of the values to be avoided. Also, chroma scale
	  factors applied to motion vectors have been replaced by shift
	  factors, so that bitshifts can be used instead of divisions for
	  greater efficiency.

2005-09-27 09:50  tjdwave

	* libdirac_common/: common.cpp, common.h: Added support for an
	  encode params flag indicating whether we're doing local decoding.
	  Local decoding can then be omitted for greater efficiency.

2005-09-27 09:44  tjdwave

	* decoder/decmain.cpp: Made timing info only output in verbose
	  mode.

2005-09-27 09:43  tjdwave

	* encoder/encmain.cpp: Added timing data for encoding.

2005-09-27 09:40  tjdwave

	* libdirac_common/arith_codec.h: Simplified ArithCodec class so
	  that probality intervals aren't used.

2005-09-07 15:29  tjdwave

	* util/encoder_gui/: COPYING, README, diracdata.h, diracgui.cpp,
	  diracgui.h, encodebox.cpp, encoder_gui.pro, filesbox.cpp,
	  main.cpp, presetbox.cpp, qualitybox.cpp, reportbox.cpp,
	  repthread.cpp, repthread.h, tables.cpp, tables.h, videobox.cpp:
	  Adding files for Dirac encoder GUI.

2005-09-07 10:41  tjdwave

	* doc/DiracSpecV0.1.doc: Version 0.1 superceded by version 0.9 now
	  in CVS.

2005-09-07 10:39  tjdwave

	* doc/DiracSpec0.9.pdf: Added decoder semantics and revised
	  bitstream structure.

2005-08-31 14:42  tjdwave

	* encoder/encmain.cpp, libdirac_common/common.cpp,
	  libdirac_common/common.h, libdirac_encoder/comp_compress.cpp,
	  libdirac_encoder/dirac_encoder.cpp,
	  libdirac_encoder/dirac_encoder.h,
	  libdirac_encoder/quality_monitor.cpp: Added support for lossless
	  I-frame and long-GOP coding, with CLI option.

2005-08-23 11:52  asuraparaju

	* ChangeLog: [no log message]

2005-08-23 11:46  asuraparaju

	* NEWS: Added 0.5.3 release notes

2005-08-23 11:14  asuraparaju

	* doc/documentation.html: Having trouble creating a pdf document in
	  which MathML is rendered correctly.  Hence a pdf version of the
	  Algorithm document cannot be generated at the moment.  Removed
	  broken link to Algorithm pdf until this problem can be fixed.

2005-08-22 13:51  asuraparaju

	* configure.ac: Update the help string for enable-mmx configure
	  argument to make it clear that MMX opts are enabled by default.
	  The user will have to explcitly specify --enable-mmmx=no or
	  --disable-mmx to disable MMX opts.

2005-08-19 13:41  asuraparaju

	* extras/patches/: README_transcode-1.0.0_dirac-0.5.x_patch,
	  transcode-1.0.0-dirac-0.5.x.patch: Dirac patch for
	  transcode-1.0.0. This patch is not a standalone patch and will be
	  effective only if the ffmpeg library it uses is built with the
	  dirac patch applied.

2005-08-19 13:38  asuraparaju

	* extras/patches/README_MPlayer-1.0pre7_dirac-0.5.x_patch: Updated
	  notes for dirac v0.5.3

2005-08-19 13:36  asuraparaju

	* extras/patches/: FFMpeg-20050806-dirac-0.5.x.patch,
	  README_FFMpeg-20050806-dirac-0.5.x_patch: Dirac patch for ffmpeg
	  cvs snapshot dated 06-Aug-2005. Note that this has been tested
	  with CVS versions as late at 16-Aug-2006 but the CVS snapshots
	  past 06-Aug-2005 are not available for download on the FFmpeg
	  server.

2005-08-19 13:34  asuraparaju

	* extras/patches/README_transcode-0.6.14_dirac-0.5.x_patch: Updated
	  for dirac v0.5.3

2005-08-19 13:33  asuraparaju

	* extras/patches/: README_ffmpeg-0.4.9-pre1-dirac-0.5.x_patch,
	  ffmpeg-0.4.9-pre1-dirac-0.5.x.patch: Updated patch for
	  dirac-0.5.3. Changed license to LGPL. Fixed bug in setting the
	  quality factor where the quality factor lookup table was uint8_t
	  instead of float which was causing the qf to be truncated to
	  uint8_t.  dirac_decode_frame now correctly returns the number of
	  bytes it consumed. This is a fix for bug 1246767.

2005-08-18 09:30  tjdwave

	* encoder/encmain.cpp: Clarified CLI error message.

2005-08-18 09:27  tjdwave

	* README: Refactored the encoding instructions so that they're much
	  clearer.

2005-08-16 15:37  asuraparaju

2005-08-15 11:24  asuraparaju

	* doc/faq.htm: Removing unwanted files in doc restructure

2005-08-15 08:34  tjdwave

	* libdirac_common/arith_codec.h: Added comment explaining look-up
	  table operation.

2005-08-12 11:58  asuraparaju

	* configure.ac: Include an extra flag to suppress warnings when
	  compiling in debug mode using icc.

2005-08-12 11:57  asuraparaju

	* README, README.developers: MMX optimisations are enabled by
	  default. Provided instructions as to how to disable it.

2005-08-12 10:26  tjdwave

	* libdirac_common/motion.cpp: Reinstated transition detection code.
	  This means that mode decision is kinder when a transition in the
	  motion vector field is detected, giving better quality in motion
	  transition areas.

2005-08-11 11:44  tjdwave

	* libdirac_common/arith_codec.h: Added Pete Bleackley's code to use
	  a look-up table for division.

2005-08-11 08:21  tjdwave

	* libdirac_common/common.cpp: Added a warning when impossible block
	  parameters are being used, and the encoder changes them.

2005-08-10 17:50  asuraparaju

	* libdirac_common/: wavelet_utils.cpp, wavelet_utils_mmx.cpp:
	  Optimised 5_3 wavelet synthesis function, VHFilter5_3::Synth,
	  using MMX instructions resulting in  6 percent speed improvement
	  in decoding SD.

2005-08-10 17:48  asuraparaju

	* libdirac_encoder/seq_compress.cpp: Fix g++ warning about unused
	  variable recode.

2005-08-10 17:47  asuraparaju

	* encoder/encmain.cpp: Print error message and exit if input and
	  output file names are the same.  Changed back cif preset option
	  to uppercase. Sequence and encoder params currently being used
	  are displayed on standard out before actual coding starts.

2005-08-10 17:45  asuraparaju

	* configure.ac: MMX optimisations are enabled by default. Use
	  --disable-mmx to explicitly disable them.

2005-08-10 09:13  tjdwave

	* README: Added modified instructions for -qf and advice about
	  -width and -height.

2005-08-10 09:06  tjdwave

	* libdirac_motionest/block_match.cpp: Changed motion vector bitrate
	  measure so that transitions from foreground to background and
	  vice-versa are not penalised.

2005-08-10 09:04  tjdwave

	* libdirac_encoder/seq_compress.cpp: Removed recoding: superfluous
	  now there is no CQ coding.

2005-08-10 09:02  tjdwave

	* libdirac_encoder/: quality_monitor.cpp, quality_monitor.h:
	  Removed constant quality encoding control mechanism, because it
	  worked too poorly for varied sequences. Instead, QualityMonitor
	  just monitors quality and encoder control reverts to constant
	  Lagrangian parameters.

	  The magic numbers chosen may not work for all sequences or all
	  video standards but will do for the moment.

2005-08-10 08:57  tjdwave

	* libdirac_decoder/comp_decompress.cpp,
	  libdirac_decoder/frame_decompress.cpp,
	  libdirac_encoder/comp_compress.cpp,
	  libdirac_encoder/frame_compress.cpp: Changed default wavelet
	  filters to fast filters APPROX97 and FIVETHREE.  Wavelet filter
	  type is now signalled in the frame header so that changing these
	  filters just changes the encoder. (This is now consistent with
	  the spec).

2005-08-10 08:50  tjdwave

	* libdirac_common/: motion.cpp, motion.h: Fixed bug with way median
	  is calculated. Removed large inline functions from .h and placed
	  in .cpp for clarity.

2005-08-10 08:48  tjdwave

	* libdirac_common/mot_comp.cpp: Minor tidy of the way that
	  weighting matrices are computed.

2005-08-10 08:44  tjdwave

	* libdirac_common/: common.cpp, common.h: Removed recode parameter.
	  Added a CodecParams parameter for the wavelet filter being used,
	  to support signalling this in the bitstream, rather than
	  selecting by frame type. (This is in the spec).

2005-08-10 08:42  tjdwave

	* libdirac_common/: bit_manager.cpp, bit_manager.h: Added support
	  for finding out the current size of bit buffers. This will
	  support future CBR implementations and calculations of bit rate
	  on the fly.

2005-08-10 08:40  tjdwave

	* libdirac_encoder/: dirac_encoder.cpp, dirac_encoder.h: Removed
	  recode option. Set block parameters for HD720 the same as for SD
	  to get around bug 1245129.  Need to fix padding and edge issues
	  to fully resolve this bug.

2005-08-10 08:27  tjdwave

	* encoder/encmain.cpp: Added feature to print out help if there's
	  an unrecognised/unparsed option.  Removed recode feature.

2005-08-01 17:14  asuraparaju

	* libdirac_decoder/dirac_parser.cpp: Speed up set_component
	  function using MMX optimisation.

2005-08-01 17:14  asuraparaju

	* libdirac_common/arrays.h: In TwoDArray<T>::Resize, free and
	  reallocate data only if the new dimensions differ from the old
	  one.

2005-08-01 17:12  asuraparaju

	* win32/VS2003/:
	  DiracDecoder/libdirac_decoder/libdirac_decoder.vcproj,
	  libdirac_common/libdirac_common.vcproj: Define HAVE_MMX macro for
	  mmx enabled targets.

2005-08-01 17:11  asuraparaju

	* util/instrumentation/process_sequence.cpp: Fix uninitialised
	  memory read bug reported by Valgrind on reaching end of sequence.

2005-08-01 17:10  asuraparaju

	* unit_tests/: motion_comp_test.cpp, motion_comp_test.h: Test all
	  MV precision values - from pixel to an eighth of a pixel.

2005-08-01 17:10  asuraparaju

	* libdirac_common/wavelet_utils_mmx.cpp: Reimplement
	  VHFilterApprox9_7::Synth and VHFilter13_5::Synth using MMX
	  optimisation.

2005-08-01 17:09  asuraparaju

	* libdirac_common/upconvert_mmx.cpp: Reimplemented
	  UpConverter::DoUpConverter function using MMX optimisation.

2005-08-01 17:07  asuraparaju

	* libdirac_common/: mot_comp_mmx.cpp, mot_comp_mmx.h:
	  Implementation of QuarterPixel::CompensateBlock function using
	  MMX optimisation.

2005-08-01 17:06  asuraparaju

	* libdirac_common/wavelet_utils.cpp: MMX version of Wavelet
	  sythesis functions are used if MMX is enabled.

2005-08-01 17:05  asuraparaju

	* libdirac_common/upconvert.cpp: MMX version of DoUpConverter is
	  used if MMX is enabled.

2005-08-01 17:04  asuraparaju

	* libdirac_common/: mot_comp.cpp, mot_comp.h: Modified the block
	  weights to be of type short to make efficient use of MMX
	  instructions. Modified CompensateComponente to make more
	  efficient use of data in cache. MMX versions of CompensateBlock
	  are used if MMX is enabled.

2005-08-01 17:04  asuraparaju

	* libdirac_common/Makefile.am: Include new mmx optimisation source
	  files and headers.

2005-07-26 10:39  tjdwave

	* libdirac_encoder/dirac_encoder.cpp: Reduced chroma weighting
	  factors in order to increase chroma fidelity - chroma bit rates
	  should increase from about 5% of total for 420 to 7.5% of total.
	  Changed default block separation for HD720 preset to remove block
	  edge overlaps at the top of the screen. This may be returned to
	  the old settings when we know why they caused the problem.

2005-07-25 18:01  mservais

	* libdirac_common/motion.cpp, libdirac_common/motion.h,
	  libdirac_common/mv_codec.cpp, libdirac_common/mv_codec.h,
	  libdirac_decoder/frame_decompress.cpp,
	  libdirac_encoder/frame_compress.cpp,
	  libdirac_motionest/global_motion.cpp,
	  libdirac_motionest/global_motion.h,
	  libdirac_motionest/me_motion_type_decn.cpp,
	  libdirac_motionest/me_motion_type_decn.h,
	  libdirac_motionest/motion_estimate.cpp,
	  libdirac_motionest/pixel_match.cpp: Minor bug fixes and added
	  some extra comments

2005-07-22 18:09  asuraparaju

	* configure.ac: updated revision to 0.5.3

2005-07-22 18:09  asuraparaju

	* libdirac_common/bit_manager.h: Updated bitstream version to 0.5
	  since the bitstream is no longer compatible with dirac-0.5.2

2005-07-22 12:59  asuraparaju

	* configure.ac: Include macro AC_SYS_LARGEFILE to overcome the 2GB
	  i/o file limit.  Fix for bug #1212581.

2005-07-21 09:11  tjdwave

	* encoder/encmain.cpp: Made presets non-case-sensitive.

2005-07-20 10:29  tjdwave

	* libdirac_encoder/dirac_encoder.cpp: Fixed bug where block
	  parameters were being set incorrectly.

2005-07-20 09:43  tjdwave

	* README: Added text about recode CLI option.

2005-07-19 16:39  tjdwave

	* encoder/encmain.cpp, libdirac_common/common.cpp,
	  libdirac_common/common.h, libdirac_encoder/dirac_encoder.cpp,
	  libdirac_encoder/dirac_encoder.h,
	  libdirac_encoder/seq_compress.cpp: Added -recode parameter. If
	  -recode [n] is present, then the encoder will recode up to n
	  times (ie will encoder up to n+1 times).

2005-07-19 15:17  tjdwave

	* libdirac_common/mv_codec.cpp,
	  libdirac_motionest/me_mode_decn.cpp: Fixed bug 1240709. Common
	  mode is now used to reduce encoding of prediction modes. Common
	  mode was also being set incorrectly in the motion estimation
	  process, which caused divergence between the encoder and decoder
	  values.  Since common mode wasn't used, this bug was masked
	  before. Both now fixed.

2005-07-08 10:26  tjdwave

	* libdirac_common/: upconvert.cpp, upconvert.h: Incorporated patch
	  1211899. This tidies up the code and makes it confirm to dirac
	  coding conventions, and also uses a smaller filter. This commit
	  differs from the patch in that the filter is not reduced to 6
	  taps but is reducted to 10 taps instead.  In the future, variable
	  filter coefficients may be supported via templated polymorphism.

2005-06-22 17:52  mservais

	* libdirac_common/motion.cpp, libdirac_common/motion.h,
	  libdirac_common/mv_codec.cpp, libdirac_common/mv_codec.h,
	  libdirac_motionest/filter_weighted_local.cpp,
	  libdirac_motionest/global_motion.cpp,
	  libdirac_motionest/global_motion.h,
	  libdirac_motionest/me_mode_decn.cpp,
	  libdirac_motionest/me_motion_type_decn.cpp,
	  libdirac_motionest/me_motion_type_decn.h,
	  libdirac_motionest/model_affine.cpp,
	  libdirac_motionest/model_affine.h,
	  libdirac_motionest/model_projective.cpp,
	  libdirac_motionest/model_projective.h,
	  libdirac_motionest/motion_estimate.cpp,
	  libdirac_motionest/pixel_match.cpp: When using global motion (but
	  not exclusively global motion), the global motion decisions can
	  now be flagged either per Prediction Unit or per Macro-Block.

	  Also, the use of a Common Mode for each Macro-Block is now
	  possible. (This had not been fully implemented before.)

2005-06-10 15:15  tjdwave

	* libdirac_encoder/quality_monitor.cpp,
	  libdirac_motionest/block_match.cpp: Fixed bug with computing MV
	  costs. Incorporated patch 1216297 for quality measurement.

2005-06-10 11:52  tjdwave

	* libdirac_encoder/dirac_encoder.cpp: Changed default block height
	  and width for motion compensation to 24 by 24 pixels from 20 by
	  20. Separation remains 16 by 16. The result is reduced blockiness
	  in areas of poor motion prediction. Downside is slower encoder,
	  but the block parameters are merely scaled-up versions of the SD
	  parameters.

2005-05-26 19:48  asuraparaju

	* extras/patches/ffmpeg-0.4.9-pre1-dirac-0.5.x.patch: Fixed bug
	  1209053. Frame size parameters are now fetched from the AV
	  context before setting frame size. Also fixed a bug where quality
	  factor was not being set correctly.

2005-05-26 16:20  stuart_hc

	* tests/samples.at: Fix bug 1209017: use -width/-height instead of
	  -x/-y

2005-05-26 16:01  stuart_hc

	* encoder/encmain.cpp: Fix bug 1209017: use -width/-height instead
	  of -x/-y Also fix SEGV when incorrect -cformat parameter is
	  passed.

2005-05-26 15:59  stuart_hc

	* README: Fix bug 1209017: use -width/-height instead of -x/-y

2005-05-25 14:30  asuraparaju

	* ChangeLog: [no log message]

2005-05-25 13:51  asuraparaju

	  and transcode to add Dirac support to these tools.

2005-05-24 08:28  tjdwave

	* libdirac_encoder/seq_compress.cpp: Fixed bug with count increment
	  so that fast adaption takes place on first recoding rather than
	  second.

2005-05-20 15:30  asuraparaju

	* README: Modified this file to remove all references to image
	  header files which are no longer required.

2005-05-20 15:25  asuraparaju

	* libdirac_encoder/seq_compress.cpp: Fix minor glitches in verbose
	  output

2005-05-20 15:02  asuraparaju

	* win32/VS2003/dirac.sln: Remove MakeHeader from list of targets as
	  contents of header files have been replaced with command line
	  arguments.

2005-05-20 15:01  asuraparaju

	* encoder/encmain.cpp, libdirac_encoder/dirac_encoder.cpp,
	  libdirac_encoder/seq_compress.cpp: Fix bugs in bit rate reporting

2005-05-20 14:05  asuraparaju

	* Makefile.am, configure.ac: make_header utility is no longer
	  required. So removing picheader directory from list of targets.

2005-05-20 13:44  asuraparaju

	* tests/: colourbars.at, create_dirac_testfile.pl, samples.at:
	  Remove all references to make_header. Sequence header information
	  is now passed to encoder on the command line.

2005-05-20 13:43  asuraparaju

	* util/instrumentation/instrmain.cpp: The encoder now writes
	  sequence header information to the instrumentation output file.
	  So read sequence info from instrumentation file.

2005-05-20 13:42  asuraparaju

	* encoder/encmain.cpp: Fix g++ errors. Write the sequence header
	  information to the instrumentation file.

2005-05-20 13:41  asuraparaju

	* libdirac_common/: pic_io.cpp, pic_io.h: Delete all code relating
	  to header file creation/reading. All sequence parameters are now
	  supplied to encoder via the command line.

2005-05-19 12:23  dirac_dev

	* decoder/decmain.cpp: Removed any references to header files.

2005-05-19 12:15  dirac_dev

	* encoder/encmain.cpp: Removed requirement of a header file. All
	  parameters are handled through command-line options. Most options
	  will still be set by the pre-set option, although they can be
	  overriden.

2005-05-19 12:03  asuraparaju

	* unit_tests/motion_comp_test.cpp: Update motion compensation tests
	  to use the helper function in MotionCompensator to instantiate
	  the MotionCompensator sub-class for the mv precision value
	  selected.

2005-05-19 11:56  asuraparaju

	* libdirac_decoder/: frame_decompress.cpp, frame_decompress.h: Now
	  reads the MV precision in the frame header.

2005-05-19 11:35  asuraparaju

	* libdirac_encoder/frame_compress.cpp: Writing the motion vector
	  precision value as part of frame header. Default mv precision is
	  set to 2 i.e. quarter pixel.

2005-05-19 11:25  asuraparaju

	* libdirac_motionest/me_utils_mmx.cpp: Fixed C/C++ aliasing
	  violations that caused a performance slow down when compiled with
	  gcc 4.0.0

2005-05-19 11:24  asuraparaju

	* libdirac_motionest/me_utils.h: Fixed gcc 4.0.0 warnings

2005-05-19 11:23  asuraparaju

	* libdirac_common/bit_manager.h: Updated bitstream version to 0.4

2005-05-19 11:21  asuraparaju

	* libdirac_common/: common.cpp, common.h: Added a field to
	  CodecParams class for motion vector precision. A value of 'n'
	  implies a precision of (2**-n)i pixel. i.e. a value of 2 implies
	  an mv precision of 1/4 i.e. quarter pixel.

2005-05-19 11:16  asuraparaju

	* libdirac_common/: mot_comp.cpp, mot_comp.h: Added support for
	  multiple levels of motion vector precision - pixel, half pixel,
	  quarter pixel and multiple pixel. The main MotionCompensator
	  class is an abstract class. Each of its sub-classes define the
	  CompensateBlock function to a particular level of motion
	  precision.

2005-05-19 11:12  asuraparaju

	* libdirac_motionest/: me_mode_decn.cpp, me_subpel.cpp,
	  motion_estimate.cpp: Motion estimation modified to support
	  variable motion vector precision. The implementation is
	  preliminary, and should be modified later: vectors are scaled by
	  a factor 8 to give a maximum of eighth-pel accuracy. Generic
	  block matching functions are used at this accuracy even though
	  true accuracy will be less - the subpixel search is merely
	  truncated.

	  In the future, half-pixel and quarter-pixel block matching
	  functions should be written, just as for motion compensation as
	  these will be faster.

2005-05-13 09:40  mservais

	* libdirac_common/mot_comp.cpp, libdirac_common/motion.cpp,
	  libdirac_common/mv_codec.cpp,
	  libdirac_motionest/me_motion_type_decn.cpp,
	  libdirac_motionest/me_motion_type_decn.h,
	  libdirac_motionest/motion_estimate.cpp,
	  win32/VS2003/ConversionUtils/BMPtoRGB/Debug/BuildLog.htm,
	  win32/VS2003/ConversionUtils/BMPtoRGB/Debug/vc70.idb,
	  win32/VS2003/ConversionUtils/BMPtoRGB/Debug/vc70.pdb: Prediction
	  units can now use either global or block motion. (Decision based
	  on similarity of global and block motion vectors.)

2005-05-11 10:13  tjdwave

	* libdirac_common/wavelet_utils.cpp: Fixed -pedantic errors on
	  unused variables. Replaced dynamic built-in array (which violates
	  ISO C++) with array class.

2005-05-05 15:10  tjdwave

	* unit_tests/wavelet_utils_test.cpp: Added support for testing all
	  different wavelet transforms for invertibility.

2005-05-04 14:35  tjdwave

	* libdirac_common/common.h, libdirac_common/wavelet_utils.cpp,
	  libdirac_common/wavelet_utils.h, libdirac_common/band_codec.cpp,
	  libdirac_decoder/comp_decompress.cpp,
	  libdirac_encoder/comp_compress.cpp: Modifications to support
	  different wavelet filter types.

	  wavelet_utils.{cpp,h} Added three new filter types with lifting
	  implementations, all much faster than Daubechies (9,7).
	  Refactored the code to support filter selection in constructor of
	  WaveletTransform class. Added method to correctly output DC band
	  expected values. Separated off coefficient interleaving and
	  deinterleaving. Setting of subband weights is now a
	  WaveletTransform function, as noise weighting factors depend on
	  the filter choice.

	  band_codec.cpp Removed literal constant and used 0 instead for
	  top-left DC value prediction.

	  comp_compress.cpp, comp_decompress.cpp Changed default filters
	  from Daubechies (9,7) to faster filters which perform almost as
	  well. This is a temporary mod. It is intended to be able to
	  select fast filters via the CLI and for wavelet filter choices to
	  be signalled in frame headers. This will be done in later
	  refactoring to converge with the bitstream syntax in terms of
	  frame types and header information.

2005-02-15 11:38  asuraparaju

	* configure.ac: Update release id to 0.5.1. Added flag to enable
	  MMX optimisation and test for checking if MMX optimising is

	  functions specific to Dirac project

2005-02-08 14:02  tjdwave

	* libdirac_common/arith_codec.h: Replaced delete with delete[] in

	*
	  win32/VS2003/DiracEncoder/libdirac_encoder/libdirac_encoder.vcproj:
	  Added quant_chooser.cpp/h

2005-02-02 14:50  tjdwave

	* libdirac_decoder/: comp_decompress.cpp, comp_decompress.h: Added
	  support for multiple code blocks/quantisers. Added separate

2005-02-02 14:49  tjdwave

	* libdirac_encoder/Makefile.am: Modded to add quant_chooser.{cpp,h}

2005-02-02 14:47  tjdwave

	* libdirac_encoder/: comp_compress.cpp, comp_compress.h,

2005-02-02 14:44  tjdwave

	* libdirac_encoder/: quant_chooser.cpp, quant_chooser.h: Added

	  quantiser per subband to be chosen, or alternatively one for each
	  code block.

2005-02-02 14:42  tjdwave

	  wavelet_utils.cpp, arith_codec.h, band_codec.h, common.h,
	  mv_codec.h, wavelet_utils.h: Modified wavelet coeff coding to
	  code blocks of coefficients. with skip flags if all coefficients
	  are zero. Wavelet coefficient coding has reduced use of class
	  member variables for clarity. The arithmetic coding and decoding
	  engines have been modified to improve speed and code
	  organisation. The decoder now reads in all the data before
	  beginning decoding. Coding of motion vector data has been tidied,
	  and modified to accommodate changes in the arithmetic coding
	  engine. Block prediction modes are now coded slightly
	  differently, which improves compression performance.

2005-01-24 16:58  tjdwave

	* libdirac_common/common.h, libdirac_common/mv_codec.cpp,
	  libdirac_common/mv_codec.h, libdirac_motionest/me_mode_decn.cpp:
	  Changed prediction of block modes to be bitwise - bit 0 indicates
	  the presence of a Ref1 MV, and bit 1 indicated the presence of a
	  Ref2 MV. This is also reflected in selecting modes in motion
	  estimation.

2005-01-24 16:06  tjdwave

	* libdirac_motionest/me_mode_decn.cpp: Re-instituted bi-directional
	  prediction, inadvertently commented out.

2005-01-24 14:43  tjdwave

	* libdirac_motionest/: block_match.cpp, block_match.h,
	  me_subpel.cpp: Made local motion vector variance a member
	  function of the block matcher, and made the cut-off limits depend
	  on the picture size. This improves performance at HD by 4% or so.

	  <sequence header> <frame-start-code> <frame 1 data> .  .  .
	  <frame-start-code> <frame n data> <sequence-end-code>

	  Sequence start code: Each sequence begins with a 5 bytes start
	  code 0x01 0x02 0x03 0x04 0xB3

	  Frame start code: Each frame begins with a 5 bytes frame start
	  code	0x01 0x02 0x03 0x04 0xB4

	  Sequence End code: Each sequence ends with a 5 bytes sequence end
	  code 0x01 0x02 0x03 0x04 0xB7

	  Not a start code flag: If the arithmetic codec ouputs the start
	  code prefix 0x01 0x02 0x03 0x04, 0xFF is inserted into the
	  bitstream to flag that this is the output of the Arithmetic codec
	  and not a start code.

	  MvData for use in motion estimation.

	  libdirac_commonm libdirac_encoder:	 Refactored output classes
	  to create classes for unit, frame and     sequence output, where
	  a unit is a subband or MV data, and consists of     a header and
	  subsequent data. Output can only be effected at the	  sequence
	  level and occurs only after a whole frame of data has been
	  accumulated.	This will allow for frames to be re-coded before
	  being     output if their quality is not satisfactory.

	* ChangeLog: Updated thislog with details of recent checkins

2004-07-16 16:29  asuraparaju

	* libdirac_encoder/quality_monitor.cpp: Fixed bug with model
	  updating - limits of slope of linear model were inaccurate. Fixed
	  bug with numerical stability of lambda re-calculation.
	  Performance with cuts or shot-changes is still poor, however.

2004-07-16 16:23  asuraparaju

	* DCO.developers, README.developers: Added contents section. Added
	  text about licensing and contribution.  Modified licensing
	  requirements so that contributors contribute under Mozilla too.
	  Added Developers Certificate of Origin, which developers are to
	  sign before their work is included.

	  Makefile.am: Changed order of make, so that utilities can use the
		  common (and other) libraries.

	  libdirac_common:     Changed EncoderParams to include a quality
	    parameter for constant-quality encoding. Changed perceptual
	  weighting to use an extension of CCIR 959 weights, with extra
	  weight for DC band, and lower weights for chroma bands.

	      Modified enumerated type CompSort to avoid name clashes by
	  using

	  member variables
	      and access functions.

	  libdirac_encoder:	Added QualityMonitor class to do
	  constant-quality     encoding. Class looks at difference between
	  locally decoded and	  original frames and adjusts Lagrangian
	  parameters appropriately.	 Simplified interface for encoding
	  results, where a single quality      parameter is specified.

	  libdirac_decoder     FrameDecompressor::Decompress now returns
	  true upon success and false	  upon failure.

	  encoder/encmain.cpp:	   Simplified interface for encoding

	  -  Included the following CVS tags in all source and header files
	     $Id: ChangeLog,v 1.29 2008/09/16 06:49:27 asuraparaju Exp $    $Name: Dirac_1_0_0 $

	  -  Included a new configuration option, --enable-debug, in
	  configure.ac. This	option turns on the flags '-Wall -pedantic
	  -Werror' to trap warnings.

	  -  Modified parameter classes in common.{h,cpp} to make member
	  variables    private and accessible through class methods. Traced
	  through codec.

	  -  Deleted context.h. The classes that were originally in this
	  file have been    integrated as nested classes into ArithCodec
	  class in arith_codec.h

	  -  Fixed bug on QCIF coding. The number of downconversions during
	     hierarchical motion estimation is now limited based on the
	  size of the	 picture

	  -  Changed decoder and encoder params to be references throughout
	  frame and    component (de)compression rather than being copied.

	  -  Code cleansed to follow coding standards specified in
	  README.developers.	 - Changed names of member variables to use
	  m_ convention     - Used spaces to improve readability of code
	   - Accessing class member variables through accessor/mutator
	  function rather	than directly	  - Non-trivial member
	  functions moved from headers to .cpp files

	     Changes mainly in the following directories:
	     libdirac_common
	     libdirac_decoder
	     libdirac_encoder

	  -  Fixed g++ compiler warnings

2004-06-22 11:10  asuraparaju

	* libdirac_common/wavelet_utils.h: Modified doxygen comments to
	  match the declaration of member function SetBandWeights in class
	  WaveletTransform.

	  seq_{de}compress and frame_{de}compress code.  Revised motion
	  compensation to use built-in arrays for weighting matrices and to
	  enforce their const-ness.  Removed unnecessary memory
	  (de)allocations from Frame class copy constructor and assignment
	  operator.

	  libdirac_decoder/comp_decompress.cpp,
	  libdirac_encoder/comp_compress.cpp,
	  libdirac_encoder/quant_chooser.cpp: Changed quantiser offsets to
	  be different for Intra and Inter frames, as per the latest draft
	  of the spec. Having an offset of 0.5*quantiser for intra frames
	  improves performance at high rate, especially iterated coding
	  with Dirac Pro apps.

2006-11-09 12:11  tjdwave

	* doc/latex_spec/: arith-encoder.tex, arith.tex,
	  layout-fullsize.tex, low-delay.tex, mc.tex, motion-dec.tex,
	  profilelevel.tex, spec-conventions.tex, spec-structure.tex,
	  wlt-dec.tex: Added more text on the low-delay syntax and decoded
	  picture buffer model.  Clarified arithmetic decoding process and
	  conventions.

2006-11-09 11:30  tjdwave

	* libdirac_common/common.cpp, libdirac_common/common.h,

	  libdirac_encoder/quant_chooser.cpp,
	  libdirac_motionest/motion_estimate.cpp,
	  libdirac_motionest/pixel_match.cpp: Overall improvements to
	  encoding framework to improve quality for difficult pictures and
	  at low bit rates. Changes to the RDO parameters are experimental
	  and they may change again.

	  - Added test for whether a frame is a B frame or not - Identified
	  Layer 1 frames with P frames and Layer 2 with B frames, rather
	  than with Inter Ref and Inter Non-ref respectively. This is more
	  efficient with the new GOP structure - Modified RDO framework to
	  provide correction where there has been ME failure i.e. lots of
	  Intra blocks - Slightly increased ME search areas - Corrected the
	  frame type parameter for the final B frame in a sequence -
	  Changed confusing terminology for costs/errors in quantisation
	  factor selection - Added overall PSNR stats for a sequence for
	  performance comparisons

2006-10-30 15:17  tjdwave

	* doc/latex_spec/: arith.tex, dataenc.tex, motion-dec.tex,
	  wlt-dec.tex: Fixed bug in specification of inverse quantisation.
	  Changed default arithmetic decoding padding value to 1 from 0, so
	  after reading in LENGTH bytes, a value of 1 is used from that
	  point. This should support early termination i.e.  encode only
	  the first few values in a subband and then the decoder will
	  correctly decode the remainder as 0, but this is as yet untested.

2006-10-30 14:57  tjdwave

	* libdirac_common/arith_codec.cpp: Fixed bug so that the decoder
	  can now append any data to the end of the arithmetically encoded
	  block and still decode correctly. Default padding data is all 1s
	  - this should make a null or terminated subband decode with
	  zeroes.

2006-10-30 13:42  tjdwave

	* libdirac_common/band_codec.cpp, libdirac_common/motion.cpp,
	  libdirac_common/motion.h, libdirac_common/mv_codec.cpp,
	  libdirac_decoder/comp_decompress.cpp: Fixed definitions of
	  mean/median so that unbiased mean values are used.  Likewise
	  changed the prediction for DC values to take account of the fact
	  that they may be negative. These changes change the bitstream.

2006-10-30 13:38  tjdwave

	* doc/latex_spec/: motion-dec.tex, spec-conventions.tex,
	  wlt-dec.tex: Changed specification of division so that it agrees
	  with C/C++ standards.  Traced through these changes to
	  specification of split mode, block dc value and intra dc band
	  prediction.

2006-10-26 16:22  tjdwave

	* libdirac_encoder/dirac_encoder.cpp: Moved to using cout instead
	  of cerr for reporting.

2006-10-26 16:07  tjdwave

	* libdirac_common/common.cpp, libdirac_common/common.h,
	  libdirac_common/frame_buffer.cpp, libdirac_common/frame_buffer.h,
	  libdirac_decoder/frame_decompress.cpp,
	  libdirac_decoder/frame_decompress.h,
	  libdirac_decoder/seq_decompress.cpp,
	  libdirac_encoder/frame_compress.cpp,
	  libdirac_encoder/seq_compress.cpp: Made  operation of retired
	  picture list comply with specification: only reference pictures
	  are signalled to be retired and non-reference pictures are
	  retired by the decoder once they are displayed.

	  Clarified frame type parameters so as to be sure they always
	  agree. This will need further refactoring.

	  Reference frames are now cleaned from the buffer _after_ being
	  the current frame has been decoded, as per the spec. This allows
	  slightly more flexible GOP structures.

2006-10-25 14:01  tjdwave

	* libdirac_common/common.cpp: Fixed bug with wrong quantiser offset
	  being used: now complies with spec again.

	  state-macros.tex, vidsys-sigrange.tex, vidsys.tex: First stab at
	  including the low-delay syntax used for Dirac Pro profiles,
	  together with profile and level text. Work in progress!

2006-10-19 16:01  tjdwave

	* doc/latex_spec/picture-dec.tex: Changed order of reference buffer
	  management so that a reference picture is not removed until after
	  the current picture has been decoded,

2006-10-19 14:53  tjdwave

	* libdirac_common/band_codec.cpp: Put in Dave Schleef's patch for
	  making the computation of parent coefficient coordinates correct
	  and spec compliant.

	* encoder/encmain.cpp, libdirac_common/common.cpp,
	  libdirac_common/dirac_types.h,
	  libdirac_encoder/dirac_encoder.cpp: Fixed bug with aspect ratio
	  being set to 0/0. Now it should be set to the correct value from
	  the video format defaults.

2006-10-09 16:24  tjdwave

	* libdirac_common/wavelet_utils_mmx.cpp: Renamed functions with
	  consistent filter names.

2006-10-05 16:22  tjdwave

	  libdirac_common/video_format_defaults.cpp,
	  libdirac_common/wavelet_utils.cpp,
	  libdirac_common/wavelet_utils.h: Given wavelet filters correct
	  names and numbers as per spec. Added support for HAAR1 and HAAR2
	  filters. FIDELITY filter will be forthcoming.

2006-09-28 14:59  tjdwave

	* libdirac_common/: common.cpp, mot_comp.cpp: Fixed the block
	  parameter testing so as to be compliant with the specification.
	  Non-overlapped blocks are now allowed and supported. The raised
	  cosine macro has now been removed and only linear weights are
	  supported.

2006-09-28 10:17  tjdwave

	  libdirac_motionest/me_mode_decn.h: Removed the Macroblock
	  "Common" mode. This means that each prediction unit within a
	  macroblock will have to code a mode. Motion data coding has also
	  been changed so that instead of coding all the prediction modes
	  first and then all the motion data, prediction modes are included
	  in the motion data as per the spec.

	  An updated version of the latex spec in which the Common mode is
	  omitted is in preparation and will be committed in the next
	  couple of weeks.

	  operations.

2006-07-18 11:36  tjdwave

	* libdirac_common/: band_codec.cpp, band_codec.h: Changed nhood sum

	  refactored data access and coefficient decoding sections.  Spec
	  should be up to date and accurate for coefficient decoding, but
	  fine-tuning and checking is required. Diagrams also needed.

	  Major change is in the way arithmetic decoding operations are
	  called. Just specify sets of contexts to be used for follow bits,
	  data bits and the sign by passing indices into the state
	  variable, which maintains the contexts.

	  This simplifies the code in the stream syntax, avoiding local
	  copies etc.  Explanation will be required for the context
	  indices. The arithmetic decoding section needs updating to
	  reflect this change and use of interleaved exp- Golomb coding.

2006-07-07 08:56  tjdwave

	* doc/latex_spec/layout-fullsize.tex: Added temporary environment
	  pseudo* for documenting _part_ of a function's pseudocode (no
	  function header).  Fixed bug where \bsRET reduces indent by 1 -
	  this broke indentation when there were a number of returns in a
	  function.

2006-07-06 12:29  tjdwave

	* libdirac_common/: band_codec.cpp, band_codec.h: Changed coding of
	  codeblock quantiser indices to be differential codeblock to

	  N.B. this now does not agree with version 0.9.

	* libdirac_common/: arith_codec.h, mv_codec.cpp, mv_codec.h: Added
	  En/DecodeUInt and En/DecodeSInt functions to the arithmetic codec
	  class. These functions read and write signed and unsigned
	  integers in a unified way. They are used to replace the acres of

2006-06-05 15:54  asuraparaju

	* libdirac_common/: wavelet_utils.cpp, wavelet_utils.h,
	  wavelet_utils_mmx.cpp: [Spec compliance] Accuracy bits are
	  required in the wavelet analysis stage. The number of bits
	  required depends on the transform depth.  Shift the input data up
	  1 bit to the right to increase accuracy in the Analyis stage.
	  Round the input data down by 1 bit in the Synthesis stage to
	  counter the shift in the analysis stage. All rounding is unbiased
	  irrespective of the number of bit it is rounded to. The
	  perceptual weights are adjusted for each subband depending on the
	  level of the subband.

	  libdirac_motionest/me_utils_mmx.cpp: [Spec Compliance] The
	  input/output is always true bit depth specified by video-depth
	  and not converted to 10 bit data internally.	So no need to shift
	  8 bit data by two to convert it to 10 bits.

	  to a Dirac bistream.

	  Dirac external API (both encoder and decoder) has changed. So the

	  no longer work with the CVS source. The external API is likely to
	  change over the next few weeks.  Updated versions of the patches
	  and Direcshow filter will be available with the next release of
	  Dirac.

	  NOTE: the bytestream has changed to largely conform to the latest
	  Dirac spec.  More work needs to be done to conform fully to the
	  Dirac definition document. So expect the CVS source and resulting
	  bitstream to change frequently over the next few weeks.

	  libdirac_encoder/comp_compress.cpp,
	  libdirac_encoder/frame_compress.cpp: Changing binarisation for
	  arithmetic coding, and associated contexts.  The specification
	  will be modified accordingly.

	  Binarisation for the magnitude values of wavelet coefficients,
	  motion vector prediction residues and DC values has been changed
	  from unary to interleaved exp-Golomb so that the number of
	  symbols to be decoded in order to reconstruct a coefficient is
	  reduced. Exp-Golomb binarisation takes a number N>=0 and codes it
	  via the binary representation of N+1, 1bbbbbb. If there are K
	  bits following the leading 1, the representation is K zeroes
	  followed by the binary representation:

	  00...01bbbbb Interleaved exp-Golomb is the same, except that the
	  K lsbs are interleaved with the zeroes: 0b0b	 0b1 so that a
	  single decoding loop can be used. The zeroes here act as "follow
	  bits" indicating that another bit is to be sent, with 1 as the
	  terminator.

	  Contexts for coding these symbols are selected for the follow
	  bits and other bits ("information bits") separately. Compression
	  performance is hardly affected, nor is speed performance in
	  software, but hardware performance is greatly facilitated.

2006-04-12 16:06  tjdwave

	* libdirac_common/arith_codec.h: Changed while loops for decoding
	  and encoding into fixed-size for-loops with break conditions.
	  Although ugly, this provides safer code as loops will terminate
	  if there's an error.

2006-04-11 12:23  asuraparaju

	* unit_tests/motion_comp_test.cpp: Set number of references in

2006-04-10 11:13  tjdwave

	* libdirac_common/band_codec.cpp: Changed lookup table-based
	  division to a straight division. This is slightly slower, but
	  will scale to higher levels of wavelet decomposition.  Also
	  eliminates bug with occasional wrap-around for lossless coding on
	  some pictures. Making abs_val 64 bits would also work but could
	  be equally slow on 32 bit architectures.

2006-03-20 12:54  asuraparaju

	  reduces the bit rate by a few bits, but the reason for doing it
	  is becuase it makes the codec more logical.  Also modified
	  BlockModePrediction so that it doesn't do a prediction for

	  inverse of weight is calculated to 16 instead of 31 bits.  3.
	  Changed scaled count of zero m_prob0 so that it's 16 bits instead
	  of 10

	  Changes 1-3 mean that m_prob0 can be worked out using only 16 bit
	  multiplies and no bitshift. This is more hardware friendly.

	  4. Modified do .. while loop for encoding and decoding so that a
	  more efficient test for MSB equality can be used, resulting in a
	  speed-up 5. Changed the order of decoding so that bits are
	  shifted in first and then the symbol is determined. This reduces
	  unnecessary bit inputs and moves to a 'lazy' input mode 6.
	  Changed the statistics update function so that m_prob0 is
	  calculated for every update rather than every other. This speeds
	  up the code and gives better compression performance.

2006-02-15 14:27  asuraparaju

	* tests/samples.at: Included  block variables so that tests can be
	  run for different block sizes. Note that the block sizes must be
	  changed manually before running the tests.

2006-02-15 14:26  asuraparaju

	* libdirac_motionest/: me_utils.cpp, me_utils_mmx.cpp,
	  pixel_match.cpp: Padding related changes. Since there may no
	  longer be an integer number of whole macroblocks and blocks in a
	  paddied picture, made changes to ensure that we do not fall off
	  the boundaries of the padded pictured during motion estimation.
	  WARNING : This changes the bitstream

	* libdirac_common/: mot_comp.cpp, mot_comp.h, mot_comp_mmx.cpp,
	  mot_comp_mmx.h: A linear function is used to calculate the OBMC
	  weights instead of a raised cosine function to make it compliant
	  with spec. Also motion compensation is performed only on true
	  picture dimensions and not padded picture dimensions, WARNING :
	  This changes the bitstream

2006-02-15 14:23  asuraparaju

	* libdirac_common/common.cpp: Modified CodecParams.SetBlockSizes
	  function to be compliant with spec.  WARNING : This changes the

	  unit_tests/motion_comp_test.cpp: Currently a frame is padded so
	  that it has an integer number of whole macro blocks and is also a
	  multiple of 2^(wavelet transform depth). This has changed in the
	  Dirac specification where a frame is padded so that its
	  dimensions are a multiple of 2^(wavelet transform depth) only.
	  Also the luma and the chroma components can be padded
	  differently. E.g. the luma dimensions may be a perfect multiple
	  of 2^(wavelet transform depth) so the luma component is not
	  padded but the chroma component may need to be padded depending
	  on the chroma format of the input.  To take care of this,
	  FrameParams class has been modified to accept both padded chroma
	  and padded luma dimensions.

	  WARNING! This modifies the bitstream.

2006-02-14 12:48  tjdwave

	* libdirac_common/arith_codec.h: Changed count rescaling so that it
	  occurs every time a bit is encoded/decoded.  This is to make
	  compliant with spec, and also because doing it every other bit
	  was giving no speed advantage.

	  WARNING! This changes the bitstream.

2006-02-10 09:49  tjdwave

	* libdirac_common/common.cpp: Modified calculation of quantisation,
	  inverse quantisation and offset values so as to conform to
	  specification.  WARNING: this modifies the bitstream.

2006-02-09 13:58  tjdwave

	* libdirac_common/: motion.h, mv_codec.cpp: Removed the function
	  for computing a mean of a vector of ints. Instead all means are
	  of unsigned int values, and are calculated using unbiased
	  arithmetic ie with an offset of N/2 for N values to ensure even
	  rounding. This changes the mean used for predicting DC values in
	  motion vector coding. As a result, the bitstream is also changed.

2006-01-06 15:56  tjdwave

	* libdirac_common/mv_codec.cpp: Changed refresh so that statistics
	  are refreshed after m_reset_num macroblocks as intended, rather
	  than m_reset_num+1.  WARNING! This changes the bitstream.

2006-01-06 15:22  asuraparaju

2005-12-01 14:25  asuraparaju

	* libdirac_common/wavelet_utils.h: New function
	  VHFilter5_3::HorizSynth which is used only when MMX opts are

	  uninitialised memory reads do not cause crashes when compiled
	  using MS VC++. Note that the data read from unitialised memory is
	  not being used but still causes problems on some platforms.

2005-12-01 14:06  asuraparaju

	* libdirac_common/mot_comp.cpp: Using calculated values of blocks
	  per macro block row and blocks per sub-block row instead of
	  hardcoded values.

2005-12-01 14:02  asuraparaju

	* util/encoder_gui/: README, diracdata.h, diracgui.cpp, diracgui.h,
	  encodebox.cpp, encoder_gui.pro, filesbox.cpp, repthread.cpp,
	  tables.h: Included option in GUI to disable the creation of
	  diagnostics data file and locally decoded output. dirac_encoder
	  need no longer be in the current working directory but in any
	  directory in the PATH variable.

2005-11-15 15:35  asuraparaju

	* libdirac_common/arith_codec.h: Minor cosmetic difference as to
	  how CODE_MSB and CODE_2ND_MSB are initialised to make their usage
	  more obvious.

2005-11-15 15:33  asuraparaju

	* doc/Makefile.am: Fix problem with install target

2005-11-08 11:45  asuraparaju

	* libdirac_common/band_codec.cpp: Minor changes in DoWorkCode,
	  DoWorkDecode and DecodeCoeffBlock functions in the way 2-D arrays
	  are accessed which resulted in a slight decoding speed
	  improvement.

2005-11-08 11:43  asuraparaju

	* libdirac_common/upconvert_mmx.cpp: Minor changes to DoUpConverter
	  routine to give slight improvement in uoconversion speed.

2005-11-08 11:41  asuraparaju

	* libdirac_common/arrays.h: In Resize function in OneDArray class,
	  dealloc and realloc data only if the new and old array sizes are
	  different.

2005-11-08 11:40  asuraparaju

	* libdirac_common/: wavelet_utils.cpp, wavelet_utils_mmx.cpp:
	  Optimised WaveletTransform::VHFilter5_3::Split using MMX
	  instructions. Minor mods to WaveletTransform::VHFilter5_3::Synth
	  function improve speed slightly.

2005-11-08 11:37  asuraparaju

	* libdirac_motionest/Makefile.am,
	  libdirac_motionest/downconvert.cpp,
	  libdirac_motionest/downconvert_mmx.cpp,
	  win32/VS2003/libdirac_motionest/libdirac_motionest.vcproj:
	  Optimised DoDownConverter routine using MMX instructions

2005-11-08 11:34  asuraparaju

	* libdirac_common/: mot_comp.cpp, mot_comp.h, mot_comp_mmx.cpp:
	  Modified motion compensation so that it take Macro-Block
	  splitting mode into consideration when compensating a row of
	  blocks. Depending on the macroblock split mode, 1,2 or 4 blocks
	  of reference data are used to calculate the motion compensated
	  data. This sped up the default quarter pixel block motion
	  compensation routine by an average of 20-23% for a 2Mbps Dirac
	  bitstream.

2005-11-08 11:26  asuraparaju

	* libdirac_common/: frame.cpp, frame.h, frame_buffer.cpp,
	  frame_buffer.h: Changes to FrameBuffer handling. Deleting old
	  frames and allocating new frames is quite expensive. So instead
	  of deleting frames no longer required in the frame buffer, they
	  are flagged "not in use". So the next time a new reference frame
	  has to be inserted in the Frame buffer, the first frame "not in
	  use" is used to store the new frame. An overall improvement of
	  6-7 percent in decoding speed for a 2Mbps bitstream resulted.

2005-10-17 12:06  asuraparaju

	* libdirac_encoder/dirac_encoder.cpp: Fixed bug #1328565. Now
	  ensuring that all locally decoded frames are available for
	  output.

2005-10-11 14:02  tjdwave

	* libdirac_common/arith_codec.h: Incorporated Steve Bearcroft's
	  speed-up patch, with some minor typographical changes for
	  clarity.

2005-10-11 10:00  tjdwave

	* libdirac_motionest/block_match.cpp: Added patch 1309571 which
	  fixes the quality degradation introduced in the motion estimation
	  speed-ups.

2005-10-07 11:17  asuraparaju

	* libdirac_motionest/: me_utils.cpp, me_utils_mmx.cpp,
	  me_utils_mmx.h: Applied MMX optimisations to modified ME
	  routines. This is an initial version that improves Motion
	  Estimation speed by 30% resulting in a 20% improvement in
	  encoding speed overall. This is work in progress.

2005-09-27 14:44  dirac_dev

	* libdirac_encoder/dirac_encoder.h: Replaced boolean with int.
	  C-compilers (eg. ffmpeg) complain about C++ constructs.

2005-09-27 14:08  tjdwave

	* libdirac_encoder/quality_monitor.cpp: Set the motion estimation
	  factor to compensate for the default search precision being at
	  1/4 pel (as this is the default precision) rather than 1/8th pel.

2005-09-27 14:07  tjdwave

	* libdirac_motionest/: motion_estimate.cpp, motion_estimate.h:
	  Removed cut detection, which is now in the FrameCompressor class.
	  Removed the kludge which scaled the motion vector precisions. All
	  motion estimation is now at the selected precision.

2005-09-27 14:01  tjdwave

	* libdirac_motionest/: me_mode_decn.cpp, me_mode_decn.h: Use
	  specific matching classes for different pixel accuracies. Reduced
	  search ranges for increased speed.

2005-09-27 13:59  tjdwave

	* libdirac_motionest/me_subpel.cpp: Removed calculation of lambda
	  map. Simplified class by using the specific subpixel refinement
	  matching function.

2005-09-27 13:55  tjdwave

	* libdirac_motionest/: pixel_match.cpp, pixel_match.h: Search
	  ranges restricted to improve motion estimation speed.

2005-09-27 13:52  tjdwave

	* libdirac_motionest/: block_match.cpp, block_match.h: Refactored
	  the BlockMatcher class. There are now three functions for finding
	  a best match - finding the pixel-accurate best match, refining
	  this to sub-pixel accuracy, and also finding a best match from a
	  list at sub-pixel level.  These matching functions contain
	  shortcuts to speed up matching as follows.

	  FindBestMatchPel: - The predictors are each searched first, and
	  if their SAD values are small then the search ends.  - bailout
	  functions are used for calculating matching costs for the
	  remaining candidates

	  RefineMatchSubpel: - The predictor from neighbouring (previously
	  refined) vectors is tested first. If there's a small SAD, then
	  the search ends - Pixel-accurate vectors are refined to half-pel
	  vectors by searching the 4 closest half-pel positions (shown as
	  X) first:  X XOX  X

	  If one of these is better than the pixel-accurate value, then the
	  two nearest values in the immediate neighbourhood of the
	  pixel-accurate value are also searched, eg the Y values below:

	  YXY XOX  X

	  This two-stage procedure is followed again in refining to
	  quarter- and eighth-pel.  - At each stage of refinement, if we're
	  10% worse than the value derived for the predictor, we end the
	  search.

	  FindBestMatchSubpel: - bailout functions are used

2005-09-27 13:40  tjdwave

	* libdirac_motionest/: me_utils.cpp, me_utils.h: Reorganised
	  classes for doing SAD calculations at pixel and sub-pixel
	  accuracy. Distinct classes for half-, quarter- and eighth-pixel
	  matching have been created. These are present also in 'bailout'
	  form so that you can leave the calculation as soon as you know
	  that you're not going to beat the best match so far.	These mods
	  support speeding up motion estimation, and hence the encoder
	  generally.

2005-09-27 12:25  asuraparaju

	* libdirac_encoder/dirac_encoder.cpp: Fixed bug# 1291478. Now
	  ensuring that dirac_encoder_output returns ENC_STATE_BUFFER when
	  data is not loaded into the encoder.

2005-09-27 12:21  asuraparaju

	*
	  doc/documentation/code/programmers_guide/decoder_api_functions.htm:
	  Bug fix: 1291481. Corrected return value in dirac_parse function
	  prototype.

2005-09-27 10:21  tjdwave

	* libdirac_encoder/seq_compress.cpp: The quality measurement model
	  can only be calculated correctly if reconstructed compressed
	  video is available, which isn't the case if we're not doing local
	  decoding. In this case, calculating and outputting these values
	  is disabled.

2005-09-27 10:16  tjdwave

	* libdirac_encoder/: frame_compress.cpp, frame_compress.h: Moved
	  the analysis of whether or not we have a cut into FrameCompressor
	  class and out of motion estimation classes.

	  Also, only do motion compensation on L2 frames if local decoding
	  is required.	This is because, by definition, L2 frames can't be
	  references and so can be left in a partially reconstructed state
	  if local decoding isn't required, which improves encoding speed.

2005-09-27 10:12  tjdwave

	* libdirac_encoder/dirac_encoder.cpp: Added support for local
	  decoding flag, so that local decoding can be avoided for speed.

2005-09-27 10:09  tjdwave

	* libdirac_encoder/comp_compress.cpp: Removed commented-out code.

2005-09-27 10:09  tjdwave

	* libdirac_encoder/comp_compress.cpp: Inverse wavelet transform is
	  now only done for L2 frames if local decoding is required. This
	  is because L2 frames are (by definition) not used for reference
	  and can be left in a partially reconstructed state if local
	  decoding isn't needed.

2005-09-27 09:54  tjdwave

	* libdirac_common/mot_comp.cpp: Introduced unbiased rounding into
	  calculation of weighting matrices. This allows the subsequent
	  rationalisation of the values to be avoided. Also, chroma scale
	  factors applied to motion vectors have been replaced by shift
	  factors, so that bitshifts can be used instead of divisions for
	  greater efficiency.

2005-09-27 09:50  tjdwave

	* libdirac_common/: common.cpp, common.h: Added support for an
	  encode params flag indicating whether we're doing local decoding.
	  Local decoding can then be omitted for greater efficiency.

2005-09-27 09:44  tjdwave

	* decoder/decmain.cpp: Made timing info only output in verbose
	  mode.

2005-09-27 09:43  tjdwave

	* encoder/encmain.cpp: Added timing data for encoding.

2005-09-27 09:40  tjdwave

	* libdirac_common/arith_codec.h: Simplified ArithCodec class so
	  that probality intervals aren't used.

2005-09-07 15:29  tjdwave

	* util/encoder_gui/: COPYING, README, diracdata.h, diracgui.cpp,
	  diracgui.h, encodebox.cpp, encoder_gui.pro, filesbox.cpp,
	  main.cpp, presetbox.cpp, qualitybox.cpp, reportbox.cpp,
	  repthread.cpp, repthread.h, tables.cpp, tables.h, videobox.cpp:
	  Adding files for Dirac encoder GUI.

	  in CVS.

2005-09-07 10:39  tjdwave

	* doc/DiracSpec0.9.pdf: Added decoder semantics and revised
	  bitstream structure.

2005-08-31 14:42  tjdwave

	* encoder/encmain.cpp, libdirac_common/common.cpp,
	  libdirac_common/common.h, libdirac_encoder/comp_compress.cpp,
	  libdirac_encoder/dirac_encoder.cpp,
	  libdirac_encoder/dirac_encoder.h,
	  libdirac_encoder/quality_monitor.cpp: Added support for lossless
	  I-frame and long-GOP coding, with CLI option.

	  Algorithm document cannot be generated at the moment.  Removed
	  broken link to Algorithm pdf until this problem can be fixed.

2005-08-22 13:51  asuraparaju

	* configure.ac: Update the help string for enable-mmx configure
	  argument to make it clear that MMX opts are enabled by default.
	  The user will have to explcitly specify --enable-mmmx=no or
	  --disable-mmx to disable MMX opts.

	* extras/patches/: README_transcode-1.0.0_dirac-0.5.x_patch,
	  transcode-1.0.0-dirac-0.5.x.patch: Dirac patch for
	  transcode-1.0.0. This patch is not a standalone patch and will be
	  effective only if the ffmpeg library it uses is built with the
	  dirac patch applied.

	  README_FFMpeg-20050806-dirac-0.5.x_patch: Dirac patch for ffmpeg
	  cvs snapshot dated 06-Aug-2005. Note that this has been tested
	  with CVS versions as late at 16-Aug-2006 but the CVS snapshots
	  past 06-Aug-2005 are not available for download on the FFmpeg

	* extras/patches/: README_ffmpeg-0.4.9-pre1-dirac-0.5.x_patch,
	  ffmpeg-0.4.9-pre1-dirac-0.5.x.patch: Updated patch for
	  dirac-0.5.3. Changed license to LGPL. Fixed bug in setting the
	  quality factor where the quality factor lookup table was uint8_t
	  instead of float which was causing the qf to be truncated to
	  uint8_t.  dirac_decode_frame now correctly returns the number of
	  bytes it consumed. This is a fix for bug 1246767.

2005-08-18 09:30  tjdwave

	* encoder/encmain.cpp: Clarified CLI error message.

2005-08-18 09:27  tjdwave

	  Committing website documentation to CVS

2005-08-15 11:24  asuraparaju

	* doc/faq.htm: Removing unwanted files in doc restructure

2005-08-15 08:34  tjdwave

	* libdirac_common/arith_codec.h: Added comment explaining look-up
	  table operation.

2005-08-12 11:58  asuraparaju

	* configure.ac: Include an extra flag to suppress warnings when
	  compiling in debug mode using icc.

2005-08-12 11:57  asuraparaju

	* README, README.developers: MMX optimisations are enabled by
	  default. Provided instructions as to how to disable it.

2005-08-12 10:26  tjdwave

	* libdirac_common/motion.cpp: Reinstated transition detection code.
	  This means that mode decision is kinder when a transition in the
	  motion vector field is detected, giving better quality in motion
	  transition areas.

2005-08-11 11:44  tjdwave

	* libdirac_common/arith_codec.h: Added Pete Bleackley's code to use
	  a look-up table for division.

2005-08-11 08:21  tjdwave

	* libdirac_common/common.cpp: Added a warning when impossible block
	  parameters are being used, and the encoder changes them.

2005-08-10 17:50  asuraparaju

	* libdirac_common/: wavelet_utils.cpp, wavelet_utils_mmx.cpp:
	  Optimised 5_3 wavelet synthesis function, VHFilter5_3::Synth,
	  using MMX instructions resulting in  6 percent speed improvement
	  in decoding SD.

2005-08-10 17:48  asuraparaju

	* libdirac_encoder/seq_compress.cpp: Fix g++ warning about unused
	  variable recode.

2005-08-10 17:47  asuraparaju

	* encoder/encmain.cpp: Print error message and exit if input and
	  output file names are the same.  Changed back cif preset option
	  to uppercase. Sequence and encoder params currently being used
	  are displayed on standard out before actual coding starts.

2005-08-10 17:45  asuraparaju

	* configure.ac: MMX optimisations are enabled by default. Use
	  --disable-mmx to explicitly disable them.

2005-08-10 09:13  tjdwave

	* README: Added modified instructions for -qf and advice about
	  -width and -height.

2005-08-10 09:06  tjdwave

	* libdirac_motionest/block_match.cpp: Changed motion vector bitrate
	  measure so that transitions from foreground to background and
	  vice-versa are not penalised.

2005-08-10 09:04  tjdwave

	* libdirac_encoder/seq_compress.cpp: Removed recoding: superfluous
	  now there is no CQ coding.

2005-08-10 09:02  tjdwave

	* libdirac_encoder/: quality_monitor.cpp, quality_monitor.h:
	  Removed constant quality encoding control mechanism, because it
	  worked too poorly for varied sequences. Instead, QualityMonitor
	  just monitors quality and encoder control reverts to constant
	  Lagrangian parameters.

	  The magic numbers chosen may not work for all sequences or all
	  video standards but will do for the moment.

2005-08-10 08:57  tjdwave

	* libdirac_decoder/comp_decompress.cpp,
	  libdirac_decoder/frame_decompress.cpp,
	  libdirac_encoder/comp_compress.cpp,
	  libdirac_encoder/frame_compress.cpp: Changed default wavelet
	  filters to fast filters APPROX97 and FIVETHREE.  Wavelet filter
	  type is now signalled in the frame header so that changing these
	  filters just changes the encoder. (This is now consistent with
	  the spec).

2005-08-10 08:50  tjdwave

	* libdirac_common/: motion.cpp, motion.h: Fixed bug with way median
	  is calculated. Removed large inline functions from .h and placed
	  in .cpp for clarity.

2005-08-10 08:48  tjdwave

	* libdirac_common/mot_comp.cpp: Minor tidy of the way that
	  weighting matrices are computed.

2005-08-10 08:44  tjdwave

	* libdirac_common/: common.cpp, common.h: Removed recode parameter.
	  Added a CodecParams parameter for the wavelet filter being used,
	  to support signalling this in the bitstream, rather than
	  selecting by frame type. (This is in the spec).

2005-08-10 08:42  tjdwave

	* libdirac_common/: bit_manager.cpp, bit_manager.h: Added support
	  for finding out the current size of bit buffers. This will
	  support future CBR implementations and calculations of bit rate
	  on the fly.

2005-08-10 08:40  tjdwave

	* libdirac_encoder/: dirac_encoder.cpp, dirac_encoder.h: Removed
	  recode option. Set block parameters for HD720 the same as for SD
	  to get around bug 1245129.  Need to fix padding and edge issues
	  to fully resolve this bug.

2005-08-10 08:27  tjdwave

	* encoder/encmain.cpp: Added feature to print out help if there's
	  an unrecognised/unparsed option.  Removed recode feature.

2005-08-01 17:14  asuraparaju

	* libdirac_decoder/dirac_parser.cpp: Speed up set_component
	  function using MMX optimisation.

2005-08-01 17:14  asuraparaju

	* libdirac_common/arrays.h: In TwoDArray<T>::Resize, free and
	  reallocate data only if the new dimensions differ from the old
	  one.

	  memory read bug reported by Valgrind on reaching end of sequence.

2005-08-01 17:10  asuraparaju

	* unit_tests/: motion_comp_test.cpp, motion_comp_test.h: Test all
	  MV precision values - from pixel to an eighth of a pixel.

2005-08-01 17:10  asuraparaju

	* libdirac_common/wavelet_utils_mmx.cpp: Reimplement
	  VHFilterApprox9_7::Synth and VHFilter13_5::Synth using MMX
	  optimisation.

2005-08-01 17:09  asuraparaju

	* libdirac_common/upconvert_mmx.cpp: Reimplemented
	  UpConverter::DoUpConverter function using MMX optimisation.

2005-08-01 17:07  asuraparaju

	* libdirac_common/: mot_comp_mmx.cpp, mot_comp_mmx.h:
	  Implementation of QuarterPixel::CompensateBlock function using
	  MMX optimisation.

2005-08-01 17:06  asuraparaju

	* libdirac_common/wavelet_utils.cpp: MMX version of Wavelet
	  sythesis functions are used if MMX is enabled.

2005-08-01 17:05  asuraparaju

	* libdirac_common/upconvert.cpp: MMX version of DoUpConverter is
	  used if MMX is enabled.

2005-08-01 17:04  asuraparaju

	* libdirac_common/: mot_comp.cpp, mot_comp.h: Modified the block
	  weights to be of type short to make efficient use of MMX
	  instructions. Modified CompensateComponente to make more
	  efficient use of data in cache. MMX versions of CompensateBlock
	  are used if MMX is enabled.

2005-08-01 17:04  asuraparaju

	* libdirac_common/Makefile.am: Include new mmx optimisation source
	  files and headers.

2005-07-26 10:39  tjdwave

	* libdirac_encoder/dirac_encoder.cpp: Reduced chroma weighting
	  factors in order to increase chroma fidelity - chroma bit rates
	  should increase from about 5% of total for 420 to 7.5% of total.
	  Changed default block separation for HD720 preset to remove block
	  edge overlaps at the top of the screen. This may be returned to
	  the old settings when we know why they caused the problem.

2005-07-22 18:09  asuraparaju

	* libdirac_common/bit_manager.h: Updated bitstream version to 0.5
	  since the bitstream is no longer compatible with dirac-0.5.2

2005-07-22 12:59  asuraparaju

	* configure.ac: Include macro AC_SYS_LARGEFILE to overcome the 2GB
	  i/o file limit.  Fix for bug #1212581.

2005-07-21 09:11  tjdwave

	* encoder/encmain.cpp: Made presets non-case-sensitive.

2005-07-20 10:29  tjdwave

	* libdirac_encoder/dirac_encoder.cpp: Fixed bug where block
	  parameters were being set incorrectly.

2005-07-20 09:43  tjdwave

	* README: Added text about recode CLI option.

	  libdirac_common/common.h, libdirac_encoder/dirac_encoder.cpp,
	  libdirac_encoder/dirac_encoder.h,
	  libdirac_encoder/seq_compress.cpp: Added -recode parameter. If
	  -recode [n] is present, then the encoder will recode up to n
	  times (ie will encoder up to n+1 times).

2005-07-19 15:17  tjdwave

	* libdirac_common/mv_codec.cpp,
	  libdirac_motionest/me_mode_decn.cpp: Fixed bug 1240709. Common
	  mode is now used to reduce encoding of prediction modes. Common
	  mode was also being set incorrectly in the motion estimation
	  process, which caused divergence between the encoder and decoder
	  values.  Since common mode wasn't used, this bug was masked
	  before. Both now fixed.

2005-07-08 10:26  tjdwave

	* libdirac_common/: upconvert.cpp, upconvert.h: Incorporated patch
	  1211899. This tidies up the code and makes it confirm to dirac
	  coding conventions, and also uses a smaller filter. This commit
	  differs from the patch in that the filter is not reduced to 6
	  taps but is reducted to 10 taps instead.  In the future, variable
	  filter coefficients may be supported via templated polymorphism.

	  Also, the use of a Common Mode for each Macro-Block is now
	  possible. (This had not been fully implemented before.)

2005-06-10 15:15  tjdwave

	* libdirac_encoder/quality_monitor.cpp,
	  libdirac_motionest/block_match.cpp: Fixed bug with computing MV
	  costs. Incorporated patch 1216297 for quality measurement.

2005-06-10 11:52  tjdwave

	* libdirac_encoder/dirac_encoder.cpp: Changed default block height
	  and width for motion compensation to 24 by 24 pixels from 20 by
	  20. Separation remains 16 by 16. The result is reduced blockiness
	  in areas of poor motion prediction. Downside is slower encoder,
	  but the block parameters are merely scaled-up versions of the SD
	  parameters.

2005-05-26 19:48  asuraparaju

	* extras/patches/ffmpeg-0.4.9-pre1-dirac-0.5.x.patch: Fixed bug

	  so that fast adaption takes place on first recoding rather than
	  second.

2005-05-20 15:30  asuraparaju

	* README: Modified this file to remove all references to image
	  header files which are no longer required.

2005-05-20 15:25  asuraparaju

	* libdirac_encoder/seq_compress.cpp: Fix minor glitches in verbose
	  output

2005-05-20 15:02  asuraparaju

	* win32/VS2003/dirac.sln: Remove MakeHeader from list of targets as
	  contents of header files have been replaced with command line
	  arguments.

2005-05-20 15:01  asuraparaju

	* encoder/encmain.cpp, libdirac_encoder/dirac_encoder.cpp,
	  libdirac_encoder/seq_compress.cpp: Fix bugs in bit rate reporting

2005-05-20 14:05  asuraparaju

	* Makefile.am, configure.ac: make_header utility is no longer
	  required. So removing picheader directory from list of targets.

2005-05-20 13:44  asuraparaju

	* tests/: colourbars.at, create_dirac_testfile.pl, samples.at:
	  Remove all references to make_header. Sequence header information
	  is now passed to encoder on the command line.

2005-05-20 13:43  asuraparaju

	* util/instrumentation/instrmain.cpp: The encoder now writes
	  sequence header information to the instrumentation output file.
	  So read sequence info from instrumentation file.

2005-05-20 13:42  asuraparaju

	* encoder/encmain.cpp: Fix g++ errors. Write the sequence header
	  information to the instrumentation file.

2005-05-20 13:41  asuraparaju

	* libdirac_common/: pic_io.cpp, pic_io.h: Delete all code relating
	  to header file creation/reading. All sequence parameters are now
	  supplied to encoder via the command line.

2005-05-19 12:23  dirac_dev

	* decoder/decmain.cpp: Removed any references to header files.

2005-05-19 12:15  dirac_dev

	* encoder/encmain.cpp: Removed requirement of a header file. All
	  parameters are handled through command-line options. Most options
	  will still be set by the pre-set option, although they can be
	  overriden.

2005-05-19 12:03  asuraparaju

	* unit_tests/motion_comp_test.cpp: Update motion compensation tests
	  to use the helper function in MotionCompensator to instantiate
	  the MotionCompensator sub-class for the mv precision value
	  selected.

2005-05-19 11:56  asuraparaju

	* libdirac_decoder/: frame_decompress.cpp, frame_decompress.h: Now
	  reads the MV precision in the frame header.

2005-05-19 11:35  asuraparaju

	* libdirac_encoder/frame_compress.cpp: Writing the motion vector
	  precision value as part of frame header. Default mv precision is
	  set to 2 i.e. quarter pixel.

2005-05-19 11:25  asuraparaju

	* libdirac_motionest/me_utils_mmx.cpp: Fixed C/C++ aliasing
	  violations that caused a performance slow down when compiled with
	  gcc 4.0.0

2005-05-19 11:24  asuraparaju

	* libdirac_motionest/me_utils.h: Fixed gcc 4.0.0 warnings

2005-05-19 11:23  asuraparaju

	* libdirac_common/bit_manager.h: Updated bitstream version to 0.4

2005-05-19 11:21  asuraparaju

	* libdirac_common/: common.cpp, common.h: Added a field to
	  CodecParams class for motion vector precision. A value of 'n'
	  implies a precision of (2**-n)i pixel. i.e. a value of 2 implies
	  an mv precision of 1/4 i.e. quarter pixel.

2005-05-19 11:16  asuraparaju

	* libdirac_common/: mot_comp.cpp, mot_comp.h: Added support for
	  multiple levels of motion vector precision - pixel, half pixel,
	  quarter pixel and multiple pixel. The main MotionCompensator
	  class is an abstract class. Each of its sub-classes define the
	  CompensateBlock function to a particular level of motion
	  precision.

2005-05-19 11:12  asuraparaju

	* libdirac_motionest/: me_mode_decn.cpp, me_subpel.cpp,
	  motion_estimate.cpp: Motion estimation modified to support
	  variable motion vector precision. The implementation is
	  preliminary, and should be modified later: vectors are scaled by
	  a factor 8 to give a maximum of eighth-pel accuracy. Generic
	  block matching functions are used at this accuracy even though
	  true accuracy will be less - the subpixel search is merely
	  truncated.

	  In the future, half-pixel and quarter-pixel block matching
	  functions should be written, just as for motion compensation as
	  these will be faster.

2005-05-13 09:40  mservais

	* libdirac_common/mot_comp.cpp, libdirac_common/motion.cpp,

	  win32/VS2003/ConversionUtils/BMPtoRGB/Debug/vc70.idb,
	  win32/VS2003/ConversionUtils/BMPtoRGB/Debug/vc70.pdb: Prediction
	  units can now use either global or block motion. (Decision based
	  on similarity of global and block motion vectors.)

2005-05-11 10:13  tjdwave

	* libdirac_common/wavelet_utils.cpp: Fixed -pedantic errors on
	  unused variables. Replaced dynamic built-in array (which violates
	  ISO C++) with array class.

2005-05-05 15:10  tjdwave

	* unit_tests/wavelet_utils_test.cpp: Added support for testing all
	  different wavelet transforms for invertibility.

2005-05-04 14:35  tjdwave

	* libdirac_common/common.h, libdirac_common/wavelet_utils.cpp,
	  libdirac_common/wavelet_utils.h, libdirac_common/band_codec.cpp,
	  libdirac_decoder/comp_decompress.cpp,
	  libdirac_encoder/comp_compress.cpp: Modifications to support
	  different wavelet filter types.

	  wavelet_utils.{cpp,h} Added three new filter types with lifting
	  implementations, all much faster than Daubechies (9,7).
	  Refactored the code to support filter selection in constructor of
	  WaveletTransform class. Added method to correctly output DC band
	  expected values. Separated off coefficient interleaving and
	  deinterleaving. Setting of subband weights is now a
	  WaveletTransform function, as noise weighting factors depend on
	  the filter choice.

	  band_codec.cpp Removed literal constant and used 0 instead for
	  top-left DC value prediction.

	  comp_compress.cpp, comp_decompress.cpp Changed default filters
	  from Daubechies (9,7) to faster filters which perform almost as
	  well. This is a temporary mod. It is intended to be able to
	  select fast filters via the CLI and for wavelet filter choices to
	  be signalled in frame headers. This will be done in later
	  refactoring to converge with the bitstream syntax in terms of
	  frame types and header information.

2005-05-04 12:13  mservais

	* libdirac_motionest/: me_motion_type_decn.cpp,
	  me_motion_type_decn.h: Introduces decision as to whether
	  individual prediction units should use Global Motion or not. (Not
	  complete yet!)

	  should use Global Motion or not. (Not complete yet!)

2005-04-13 16:36  asuraparaju

	* libdirac_common/arrays.h: New constants PIXEL_VALUE_MIN and
	  PIXEL_VALUE_MAX to define the upper and lower limits on pixel
	  values.

2005-04-13 16:28  asuraparaju

	* libdirac_common/frame.cpp: Included an MMX implementation of
	  Frame::ClipComponent to achieve a decoding speedup in conjuction
	  with mot_comp.cpp changes. Also using pointer arithmetic insted
	  of index operator when accessing TwoDArray objects.

2005-04-13 16:25  asuraparaju

	* libdirac_motionest/me_utils_mmx.cpp: Using pointer arithmetic
	  instead of the index operator when using TwoDArray objects to get
	  an overall slight improvement in encoding speed.

2005-04-13 16:16  asuraparaju

	* libdirac_common/mot_comp.cpp: Partially applied patch 1151976.
	  Using pointer arithmetic instead of index operator to access
	  TwoDArray objects. A few other tweaks to improve cache locality.

2005-04-13 16:09  asuraparaju

	* libdirac_encoder/quant_chooser.cpp: Fix errors reported by
	  MIPSPro C++ compiler regarding not specifiying the namespace for
	  math functions like floor and log.

2005-04-13 16:06  asuraparaju

	* libdirac_common/arith_codec.h: Fix g++ warning re unused
	  variables.

2005-04-13 16:06  asuraparaju

	* configure.ac: Included icc compile time flag -wr964 to treat
	  warning 964 as a remark when mmx is enabled.

2005-04-12 11:56  timborer

	* doc/DiracSpecV0.1.doc: Modifed default Motion Vector precision
	  (now 1/4 pel), added note that max MV precision should be
	  included in Level. Corrected typos.

2005-04-06 15:31  tjdwave

	* libdirac_common/: band_codec.cpp, band_codec.h, mv_codec.cpp,
	  mv_codec.h: Oops. Correct files now uploaded.

2005-04-06 15:28  tjdwave

	* libdirac_common/: band_codec.cpp, band_codec.h, mv_codec.cpp,
	  mv_codec.h: Changes to reflect mods to arith_codec.h: in
	  particular, Update is removed as this is no longer a virtual
	  function. Instead the base class function is called directly in
	  the encoding/decoding engines.

2005-04-06 15:07  tjdwave

	* libdirac_common/arith_codec.h: Speed-up to arithmetic coding and
	  decoding, using probability range renormalisation to avoid
	  unnecessary divides.

2005-04-05 14:56  timborer

	* doc/DiracSpecV0.1.doc: Initial draft of Dirac spec. This is not a
	  specification of what we have but a proposed spec for what we
	  want. At the moment it focuses on syntax rather than semantics.
	  It is inkorect and incomplet.

2005-03-17 11:21  mservais

	  all input formats supported by Dirac.

2005-02-15 11:21  asuraparaju

	* libdirac_motionest/: Makefile.am, me_utils.cpp, me_utils_mmx.cpp,

	  warnings

2005-02-15 11:13  asuraparaju

	* acinclude.m4: File containing user defined autoconf macro
	  functions specific to Dirac project

2005-02-08 14:02  tjdwave

	* libdirac_common/arith_codec.h: Replaced delete with delete[] in
	  destructor. Added clean-up in data reading so that the class can
	  be re-used without causing a memory leak.

2005-02-07 12:12  tjdwave

	* libdirac_encoder/comp_compress.cpp,
	  libdirac_decoder/comp_decompress.cpp: Fixed bug where blocks of

2005-02-02 15:24  dirac_dev

	*
	  win32/VS2003/DiracEncoder/libdirac_encoder/libdirac_encoder.vcproj:
	  Added quant_chooser.cpp/h

2005-02-02 14:50  tjdwave

	* libdirac_decoder/: comp_decompress.cpp, comp_decompress.h: Added
	  support for multiple code blocks/quantisers. Added separate
	  function for reading header.

2005-02-02 14:49  tjdwave

	* libdirac_encoder/Makefile.am: Modded to add quant_chooser.{cpp,h}

2005-02-02 14:47  tjdwave

	* libdirac_encoder/: comp_compress.cpp, comp_compress.h,

	  selection from comp_compress to another class.

2005-02-02 14:46  tjdwave

	* libdirac_encoder/: quant_chooser.cpp, quant_chooser.h: Modified
	  author details.

2005-02-02 14:44  tjdwave

	* libdirac_encoder/: quant_chooser.cpp, quant_chooser.h: Added
	  classes to handle selecting quantisers. These allow a single
	  quantiser per subband to be chosen, or alternatively one for each
	  code block.

2005-02-02 14:42  tjdwave

	* libdirac_common/: band_codec.cpp, common.cpp, mv_codec.cpp,
	  wavelet_utils.cpp, arith_codec.h, band_codec.h, common.h,
	  mv_codec.h, wavelet_utils.h: Modified wavelet coeff coding to
	  code blocks of coefficients. with skip flags if all coefficients
	  are zero. Wavelet coefficient coding has reduced use of class
	  member variables for clarity. The arithmetic coding and decoding
	  engines have been modified to improve speed and code
	  organisation. The decoder now reads in all the data before
	  beginning decoding. Coding of motion vector data has been tidied,
	  and modified to accommodate changes in the arithmetic coding
	  engine. Block prediction modes are now coded slightly
	  differently, which improves compression performance.

2005-01-24 16:58  tjdwave

	* libdirac_common/common.h, libdirac_common/mv_codec.cpp,
	  libdirac_common/mv_codec.h, libdirac_motionest/me_mode_decn.cpp:
	  Changed prediction of block modes to be bitwise - bit 0 indicates
	  the presence of a Ref1 MV, and bit 1 indicated the presence of a
	  Ref2 MV. This is also reflected in selecting modes in motion
	  estimation.

2005-01-24 16:06  tjdwave

	* libdirac_motionest/me_mode_decn.cpp: Re-instituted bi-directional
	  prediction, inadvertently commented out.

2005-01-24 14:43  tjdwave

	* libdirac_motionest/: block_match.cpp, block_match.h,
	  me_subpel.cpp: Made local motion vector variance a member
	  function of the block matcher, and made the cut-off limits depend
	  on the picture size. This improves performance at HD by 4% or so.

	  been modified to be able to parse it for decoding.

	  BitStream Changes:

	  The new dirac bit stream is as follows <sequence-start-code>
	  <sequence header> <frame-start-code> <frame 1 data> .  .  .
	  <frame-start-code> <frame n data> <sequence-end-code>

	  Sequence start code: Each sequence begins with a 5 bytes start
	  code 0x01 0x02 0x03 0x04 0xB3

	  Frame start code: Each frame begins with a 5 bytes frame start
	  code	0x01 0x02 0x03 0x04 0xB4

	  Sequence End code: Each sequence ends with a 5 bytes sequence end
	  code 0x01 0x02 0x03 0x04 0xB7

	  Not a start code flag: If the arithmetic codec ouputs the start
	  code prefix 0x01 0x02 0x03 0x04, 0xFF is inserted into the
	  bitstream to flag that this is the output of the Arithmetic codec
	  and not a start code.

2004-08-11 14:27  asuraparaju

	* configure.ac: Added a new option --enable-profile to include the
	  profiling option -pg to them compile line. Setting up CXXFLAGS

	  libdirac_common, libdirac_encoder, libdirac_motionest:     Added
	  lifting classes for wavelet transform. Refactored motion
	  estimation to make logic clearer, and added separate
	  pixel-accurate matching classes.  Put in a longer temporal filter
	      in QualityMonitor class to reduce oscillation and changed

	  MvData for use in motion estimation.

	  libdirac_commonm libdirac_encoder:	 Refactored output classes
	  to create classes for unit, frame and     sequence output, where
	  a unit is a subband or MV data, and consists of     a header and
	  subsequent data. Output can only be effected at the	  sequence
	  level and occurs only after a whole frame of data has been
	  accumulated.	This will allow for frames to be re-coded before
	  being     output if their quality is not satisfactory.

	  Revision 1.21  2006/11/13 12:28:22  tjdwave
	  *** empty log message ***
	    $Revision: 1.29 $

	  -  Included the following CVS tags in all source and header files
	     $Id: ChangeLog,v 1.29 2008/09/16 06:49:27 asuraparaju Exp $    $Name: Dirac_1_0_0 $

	  -  Included a new configuration option, --enable-debug, in
	  configure.ac. This	option turns on the flags '-Wall -pedantic
	  -Werror' to trap warnings.

	  -  Modified parameter classes in common.{h,cpp} to make member
	  variables    private and accessible through class methods. Traced
	  through codec.

	  -  Deleted context.h. The classes that were originally in this
	  file have been    integrated as nested classes into ArithCodec
	  class in arith_codec.h

	  -  Fixed bug on QCIF coding. The number of downconversions during
	     hierarchical motion estimation is now limited based on the
	  size of the	 picture

	  -  Changed decoder and encoder params to be references throughout
	  frame and    component (de)compression rather than being copied.

	  -  Code cleansed to follow coding standards specified in
	  README.developers.	 - Changed names of member variables to use
	  m_ convention     - Used spaces to improve readability of code
	   - Accessing class member variables through accessor/mutator
	  function rather	than directly	  - Non-trivial member
	  functions moved from headers to .cpp files

	     Changes mainly in the following directories:
	     libdirac_common
	     libdirac_decoder
	     libdirac_encoder

	  -  Fixed g++ compiler warnings

2004-06-22 11:10  asuraparaju

	* libdirac_common/wavelet_utils.h: Modified doxygen comments to
	  match the declaration of member function SetBandWeights in class
	  WaveletTransform.

2004-06-22 11:08  asuraparaju

	* encoder/encmain.cpp: Fixed compilation errors caused by trying to
	  access non-existent cformat data member in class EncoderParams.

	  libdirac_encoder/seq_compress.cpp,
	  libdirac_motionest/motion_estimate.cpp,
	  libdirac_common/motion.cpp, libdirac_common/motion.h: Removed
	  chroma format parameter cformat from CodecParams and derived
	  classes to avoid duplication. Made consequential minor mods to
	  seq_{de}compress and frame_{de}compress code.  Revised motion
	  compensation to use built-in arrays for weighting matrices and to
	  enforce their const-ness.  Removed unnecessary memory
	  (de)allocations from Frame class copy constructor and assignment
	  operator.
