2008-07-12 - xvidenc 7.9.3
	* Added Vorbis audio support for the Matroska container
	* Feature request: add the possibility to disable MEncoder's A/V sync
	  algorithm when encoding video files. This can be used to fix input
	  video files with bad A/V sync in them, however there are no
	  guarantees that this will actually fix the problem
	* Enabled back the use of temporary directories based on process ID
	  to store config files
	* Do not ask for FPS conversion or pullup/pulldown if the user forces an
	  output frame rate
	* Updated the requirements part in the README.xvidenc file
	* Small clean ups
	
2008-07-05 - xvidenc 7.9.2
	* Added two anime presets: ani and anihq
	* Bugfix: multi-channel audio was not enabled for the neroAAC audio codec
	* Feature request: add the possibility to specify the path to MEncoder.
	  Useful if the user has two or more versions of MEncoder but wants to
	  use a specific one for the encoding
	* Changed default unsharp mask / gaussian blur matrix to chroma & luma 5x5
	  as it provides a better balance than the 3x3 matrix
	* Check to see if destination directory is writable by writing a small
	  file to it.
	* Updated the man page

2008-07-01 - xvidenc 7.9.1
	* Added support for using the neroAacEnc AAC audio encoder with
	  LC, HE and HEv2 profiles
	* Function renaming: aacplus_audio_func() -> neroaac_audio_func()
	* Variable renaming: aacplusbr -> neroaacbr
	* Audio codec renaming: AAC+ -> neroAAC

2008-06-24 - xvidenc 7.9.0
	* Disabled the use of unique temporary directories to store temporary
	  configuration files. This fixes an MP4Box crash on newer systems
	* Removed reference to the Sonic audio codec in the -sc option as
	  this codec is no longer supported

2008-06-19 - xvidenc 7.8.9
	* Added support for inclusion of external subtitles when encoding
	  video files. The external subtitle will be hard coded into the
	  encode
	* Updated the man page

2008-06-16 - xvidenc 7.8.8
	* Removed none existant -sv option from the help menu

2008-05-30 - xvidenc 7.8.7
	* Small menu enhancements to the FPS settings
	* Fixed wrong explanation for the temporal denoiser
	* Removed support for the Sonic and SonicLS audio codecs since they
	  are experimental and far from complete for daily use
	* Updated the man page

2008-04-28 - xvidenc 7.8.6
	* Implemented source_fps_func() function to reduce code duplication.
	  This function automatically detects the FPS of the content and is
	  shared between the deinterlace and interlace functions
	* Added support for applying denoising/deblocking on interlaced content.
	  This is done by deinterleaving the content with the il=d filter, applying
	  the denoising/deblocking on the deinterleaved content and interleaving it
	  back with the il=i filter. That way we don't break the interlacing
	* Color enhancements to the -bpp and -bpb options

2008-04-26 - xvidenc 7.8.5
	* Fixed a problem where the detected resolution based on the crop values
	  favored the values of the cropdetect filter instead of the user
	  provided values. Reported by blaz from the Doom9 forum
	* Clarify that the aspect ratio is the one for input sources
	* Renamed resolution variable 'res' to 'vres'
	* Set the field dominance of the frame doubling yadif deinterlacer
	  to auto detection
	* Added support for doing 25 -> 50 fps and 29.970 -> 59.940 fps conversion
	  using simple frame duplication
	* Updated the man page

2008-04-23 - xvidenc 7.8.4
	* Bugfix for the audio menu. AC3 is not supported yet in the MP4 container.
	* Updated the audio_channels_func() function
	* Added support for video bitrate calculation when using 5 channels PCM audio
	* Updated the --help section
	* Set the field dominance of the yadif deinterlacer to auto-detection. If
	  the decoder doesn't export the field order, it defaults to TFF (top field first)
	* Small menu enhancements to the video_interlace_func() function

2008-04-20 - xvidenc 7.8.3
	* Updated the filmdint FPS conversion filter. Added dint_thres=256 to
	  not do any deinterlacing while doing the conversion
	* Small update to the FPS conversion menu
	* Updated the audio codecs menu
	* Removed delay when exiting from user interrupt
	* Updated the README.encoding file
	* Updated the man page

2008-04-15 - xvidenc 7.8.2
	* Replace underscores from DVD title names with spaces
	* Added support for NTSC Double @ 60 fps
	* Fixed the cropping code. NTSC content was problematic

2008-04-08 - xvidenc 7.8.1
	* Integrated the exit command into the rmconf() function
	* Fixed color output in the target file size calculation
	* Updated the cropping code to support the latest SVN version of MEncoder
	* Small clean ups

2008-03-28 - xvidenc 7.8.0
	* Use awk to get the current device when exporting DVD chapters information
	* When encoding specific chapters, append the chapters info at the end of
	  the output file
	* Removed support for MP3 high- and lowpass frequency settings. I'm sure many people
	  don't use these options and accept the defaults
	* Removed support for manual video codec configuration. This reduces the code
	  and makes it less bloated. Only presets are supported now
	* The turbo option is now hard coded into the first pass of a 2-pass encoding mode
	* Threads are now auto-detected based on the number of CPUs/cores. Note that Xvid
	  is single-threaded and it only uses threads for its motion estimation
	* Updated the README.xvidenc file. Added links for neroAacEnc and Vorbis
	* Updated the man page
	
2008-03-23 - xvidenc 7.7.9
	* Removed accurate rounding of the software scaler since it does not
	  work on a lot of systems
	* Be silent when doing FPS conversion
	* Updated the README.xvidenc file

2008-03-19 - xvidenc 7.7.8
	* Removed niceness from the muxing commands
	* Added -nocache mplayer option to the AAC+/vorbis muxing/exporting code
	* Clean ups to the batch exporting code
	* Replaced an 'if' conditional with a 'case' one in the AAC+/Vorbis batch
	  exporting code
	* Use -vf rectangle=<crop_values> when previewing the crop values. Will
	  give us a nice outline of the crop values

2008-03-13 - xvidenc 7.7.7
	* Added support for CBR AAC+ audio
	* Made the CBR part of the audio codecs to be menu driven
	* Fixed a bug where the FPS conversion menu and the Telecine/IVTC don't
	  show up due to missing interlacing variable. Bug was introduced during
	  the grouping of the pre/postprocessing video filters
	* Set default QP parameter to 0 for the spp, fspp and uspp
	  postprocessing filters

2008-03-10 - xvidenc 7.7.6
	* Major simplifications to the MP4 muxing code
	* Only extract audio and video if we deal with the AAC+ or Vorbis
	  audio codec
	* Disabled accurate rounding of the software scaler on 64-bit systems
	  since MEncoder has issues with it
	* Disabled the scalable sample rate option of the FAAC menu
	  since it does not work. FAAC doesn't support HE-AAC
	* Added checking for oggenc and neroAacEnc to the -sc option
	* Color optimizations
	* Use named pipes (fifo) to encode to AAC+ or Vorbis audio. This
	  eliminates the audio dumping step and the required disk space
	* Updated the batch code to support named pipes
	* Pre/Postprocessing video filters are now grouped in one question
	* Added autocompletion support. Patch by Nicolas Di Pietro
	* Added a skip option to most of the menus

2008-03-06 - xvidenc 7.7.5
	* Merged the -sv option with -scan
	* Video bitrate calculation: fixed the PCM part. It needs different
	  bitrates for different audio channels. Resampling is not taken into
	  account.
	* Added support for the HE-AAC (aka AAC+) audio codec. This requires
	  neroAacEnc. When encoding to this codec, the AVI will be first encoded
	  with PCM audio. Then both the video and audio will be extracted from
	  the AVI, the audio will be encoded to AAC+ and will be muxed together
	  with the video to the mp4 container. Multichannel AAC+ audio is not
	  supported yet. Only the mp4 container is supported at the moment
	  as mkvmerge does not support RAW Xvid streams
	* Added support for the Vorbis audio codec. The procedures for this
	  codec are the same as those for AAC+. Multichannel audio is supported.
	  As is the case with AAC+, only the mp4 container is supported
	* Updated the batch code to support AAC+ and Vorbis audio
	* Fixed the HW presets. Added -noodml option as OpenDML AVIs can cause
	  problems on some HW players
	* Added support for exporting the MP4 muxing commands to the batch file
	  when using the NOSOUND audio option
	* Updated the signal traps
	* Replaced an 'if' conditional by a 'case' one in the video bitrate
	  calculation code
	* Updated the README.xvidenc file
	* Updated the man page

2008-03-04 - xvidenc 7.7.4
	* Removed options 2, 3, 4 and 5 of the 60p -> 24p FPS conversion menu
	  as these filter chains are not very reliable and often fail at doing
	  the conversion. Also removed support for the decimate filter so now
	  only framestep and filmdint are supported which give the best results
	* Refined the filmdint filter parameters for 60p -> 24p FPS conversion
	  and set default filter to filmdint=fast=0/io=60:24
	* Remove config directory on non-zero exit status
	* Updated the man page

2008-03-02 - xvidenc 7.7.3
	* Added support for 30p -> 24p FPS conversion
	* Added support for the decimate filter when doing 60p -> 24p
	  FPS conversion
	* Small improvements to the crop preview code. Should come after
	  the user has entered the crop values
	* Video file encodings: Use unique default output file based on
	  process ID
	* Fixed a small bug where xvidenc assumes that the $HOME/.xvidenc
	  directory already exists but that might not be the case, so it
	  will fail at making an unique temporary directory. Reported by
	  Nathaniel Gray
	* Added support for setting the quantization parameter for the
	  spp, uspp and fspp postprocessing filters

2008-03-01 - xvidenc 7.7.2
	* Notify the user that the frame rate will change when using the
	  inverse telecine/telecine filters
	* Improvements to the batch exporting code
	* Added support for doing 60p -> 30p, 60p -> 24p and 50p -> 25p
	  FPS conversion. Useful for HD content that runs at 59.94 or 50 fps
	  This option is mutually exclusive with interlacing and frame doubling
	  deinterlacing filters
	* Removed the '-p help' option as it is not very useful. --help
	  displays everything one needs to know
	* Fixed a bug in the batch exporting code of the MP4 part where
	  muxing fails when using the MP3 audio codec due to undefined
	  input file
	* Disabled colorspace conversion when interlacing, telecining or
	  when doing FPS conversion as some (most?) filters don't like it
	* Made the script to use unique temporary directories to store
	  the config/parsing files. That way, one can run multiple
	  instances of xvidenc at the same time without interference
	* Modified the batch exporting code to work with unique
	  directories
	* Colorized automatic actions/info/menus
	* Updated the man page

2008-02-26 - xvidenc 7.7.1
	* Added 4 stand-alone HW compatible presets (hwsdpal, hwsdntsc,
	  hwhdpal and hwhdntsc)
	* Clean ups in the MP4 muxing code
	* Bugfix: enabled MP4 and OGM muxing when using the default
	  audio codec (mp3). The bug was introduced while converting the
	  muxing code to base its decision on variable $audiocodec
	  instead of $audcodec which is no longer available
	* Updated the man page

2008-02-25 - xvidenc 7.7.0
	* Removed the 'user defined' option from the deint_custom_fps_func()
	  function as it can confuse users who don't really know what to
	  enter there
	* Added support for different audio resampling modes
	* Added support for the 'lavcresample' audio resample filter
	* Made the audio_resample_func() function to be menu driven
	* Converted the MKV/MP4/OGM code to base its decision on
	  variable $audiocodec instead of variable $audcodec. Makes
	  the code less complicated
	* Added support for calculating the video bitrate when encoding with
	  the NOSOUND audio option
	* Added support for calculating the video bitrate when encoding with
	  the PCM audio codec
	* Made the code for the bicubic software scaler parameters to
	  be menu driven
	* Enabled AAC audio support for the Matroska container. Please
	  upgrade your mkvtoolnix to the latest SVN version!
	* Added support for automatic detection of the video aspect
	* Don't continue if MEncoder exits with a non-zero status
	* Small improvements to the DVD titles scanning code
	* Small improvements to the check_diskspace_func() function
	* Updated the -sc option
	* Variable renamings

2007-02-20 - xvidenc 7.6.9
	* Fixed a bug in the deint_custom_fps_func() function. Variable
	  deintfsp for NTSC @ 59.94 fps should be deintfps
	* Fixed a bug in option 8 of the $dfilter variable which was
	  using a invalid underscore. Should be -field-dominance 1
	  instead of -field_dominance 1
	* Clean ups of old commented out code
	* Reordered the deinterlacing menu. Separated the normal deinterlacers
	  from the frame doubling ones.
	* Small improvements to the audio_channels_func() function
	* Updated the README.xvidenc file

2007-02-18 - xvidenc 7.6.8
	* Updated the DVD chapters code to support the latest SVN version
	  of MEncoder
	* Small improvements to the cropping code
	* Fall back to 'dd' for ISO dumps if 'pv' is not available on
	  the user's system
	* Set default noise pattern to be Luma + temporal instead of
	  Luma & Chroma + temporal
	* Added support for the lossless format of the Sonic audio codec
	* Rplaced a few 'if' conditionals with 'case' conditionals
	* Bugifx: the ivtc/telecine process should check for the $deintfilter
	  variable instead of the $deintfps one. ivtc/telecine is mutually
	  exclusive with deinterlacing
	* Improvements to the MP4 muxing part when exporting the options to
	  the batch file. From now on, the FPS needed for MP4Box is directly
	  taken from the AVI file. This approach is much more reliable and the
	  user no longer needs to edit the FPS value for MP4Box when exporting
	  the options of NTSC content.
	* Moved all of the audio codecs code into functions. Easier to
	  maintain
	* Added supprot for the Tfields deinterlacer @ original frame speed
	  and Tfields + fast/medium/slow/slowest Mcdeint @ original frame speed

2008-02-14 - xvidenc 7.6.7
	* Export testing condition to the batch file for the output of MEncoder
	  and for the output directory as well
	* Changed FPS naming for Silent Speed to Silent Film
	* Added support for automatic brightness/contrast control
	* Bugfix: Only ask for deletion of the AVI file if the user has chosen
	  to remux it to one of the supported containers
	* Removed duplicate $quiet variable in the video_deinterlace_func()
	  function when deinterlacing with a frame doubler
	* Modified the -iso option to use 'pv' for DVD ISO dumping instead of
	  'dd'. 'pv' provides us with a nice progress bar which is useful as
	  it takes a long time to dump a DVD, so the user can follow the
	  progress. 'dd' provides no such thing.
	* Updated the -iso option to support dual-layer DVDs (~8.54 GB)
	* Added support for setting the subtitle alignment
	* Added support for setting the subtitle Gaussian variance strength
	  when hardcoding subtitles into the movie
	* Use $IDXFILE variable for the MP4SUB and MKVSUB variables
	* Various small code improvements
	* Updated the man page

2008-02-12 - xvidenc 7.6.6
	* Replaced some more 'sed' commands with 'awk'
	* Made the deint_custom_fps_func() function to be menu driven
	* Implemented -iso option for dumping the DVD content with 'dd'
	  to an ISO image to disk
	* Variable renamings and small clean ups
	* Added 'sleep 3' delay for the exported options
	* Use detected FPS value in the bits_per_pixel_func() and
	  bits_per_block_func() functions instead of falling back to 25
	  if the user doesn't set/force the FPS value
	* Changed the -o option to -b to better reflect that this option
	  is for batch encoding. Also default output file of the options
	  file will be $HOME/batchfile
	* Updated the FPS values for VFR Anime sources and Silent Speed films
	* Updated the AUTHORS file
	* Updated the man page

2008-02-10 - xvidenc 7.6.5
	* Added support for the OGM container
	* Removed support for file splitting as the code/operation is
	  not very reliable, especially with embedded subs in the MKV/MP4
	  containers. Further, the code to support 4 containers is pretty
	  large and unmanageable
	* Added the -tmp flag to the MP4Box commands to not run out of
	  disk space in case of large files. Suggested by Henk Schoneveld
	* Added the -field-dominance flag to the MEncoder parameters for
	  deinterlacers that support setting the field order
	* Added support for fast/medium/slow/slowest mcdeint combined
	  with the Yadif and Tfields deinterlacers
	* Changed variable $df to $dfilter
	* Replaced a few 'sed' commands with 'awk'
	* Small clean ups

2008-02-08 - xvidenc 7.6.4
	* Renamed variable $audio_codec to $audcodec
	* Added support for exporting the fps value when exporting
	  the MP4Box commands to the options file. It's still not 100%
	  reliable 'cause of the NTSC crapware!
	* Disabled exporting the MP4 muxing commands to the options file
	  when using NOSOUND as the code base does not allow it
	* Simplified the MP4 muxing code a bit. This reduces a bit of
	  code duplication
	* Notify the user that the frame rate will change if he is
	  interlacing progressive content
	* Remove displaying "Checking for lsdvd..." every time the
	  user chooses for DVD encoding
	* Don't enable interlace-aware software scaler when telecining
	  progressive content as the telecine filter comes after the
	  scale filter
	* Cosmetics: forgot a few 'echo' statements in the
	  video_deblock_func() function
	* Improvements to the video_deinterlace_func() and video_interlace_func()
	  functions
	* Removed support for optimization of the MP4 file layout as
	  the 'mpeg4ip' tools are no longer actively developed
	* Some improvements to the audio scanning menu
	* Some clean ups

2008-02-06 - xvidenc 7.6.3
	* Added support for setting/forcing the video aspect ratio
	* Added support for exporting the Matroska muxing commands
	  into the options file
	* Added support for adding noise to the encoding with the
	  'noise' video filter
	* Added support for exporting the MP4 muxing commands to the
	  options file. Note that FPS detection is not exported so
	  you'll have to edit the options file and set the correct
	  FPS value for MP4Box if you don't want to have any A/V
	  sync problems!
	* Added support for previewing the crop values for 15 seconds
	* Updated the man page

2008-02-04 - xvidenc 7.6.2
	* Made the custom FPS code for deinterlacing a function. This
	  reduces code duplication
	* Added support for deblocking-only of DVDs/video files with
	  the ha/va filters
	* Reordered the input frame rate selection menu of the
	  video_interlace_func() function
	* Added support for the Sonic audio codec
	* Changed contact email address due to some issues with my current
	  ISP provider
	* Updated the man page
	* Comments clean ups

2008-01-31 - xvidenc 7.6.1.1
	* Fixed a potential bug where MP4Box/mkvmerge can fail to parse
	  the filename of the subtitle during importing

2008-01-24 - xvidenc 7.6.1
	* Bugfix: added a condition to check if the 'tfields' filter is used,
	  and if so, to place it after the crop filter. The reason for this is
	  that 'tfields' alters the resolution and if this filter comes before
	  the crop filter, the crop values will no longer be correct so
	  MEncoder will error out with a "crop area outside of the original"
	  message.
	* Implemented menu driven -scan option for DVD information. With
	  -scan one can display extensive information about a DVD or
	  can export the information to a file on disk in text, perl,
	  python, ruby or xml format.
	* Added support for auto-detection of the FPS value and setting it
	  to double when deinterlacing with a frame doubling deinterlacer
	* Added a note that NTSC FPS detection is not 100% reliable. This
	  comes from the fact that xvidenc only detects the FPS flag set
	  in the video content but many NTSC DVDs "lie" about their true
	  FPS value
	* Enabled hq_ac for the NLQ profile
	* Updated the deinterlacing menu
	* Added the -nocache option to MPlayer for faster execution
	* Updated the signal traps
	* Updated the man page

2008-01-21 - xvidenc 7.6.0
	* Made the audio codec selection to be menu driven.
	* Made scanning for multiple audio streams in video files
	  to be optional.
	* Added back support for the old ha/va/dr postprocessing
	  deblock/dering filters.
	* Added support for interleaving even lines from even frames
	  with odd lines from odd frames with the 'tinterlace' filter
	  in mode 4
	* Added support for the frame doubling 'tfields' temporal fields
	  filter and 'tfields' + 'mcdeint'
	* Enabled chrominance filtering for the temporal 'tn' denoiser
	* Some small code improvements to the 'sed' parsing.
	* Cleanups in the quality presets. Made the 2-pass $turbo
	  variable to be global instead of per preset based. This
	  reduces code duplication.
	* Fixed a small bug when using user defined frame rate during
	  the frame doubling deinterlacing process. Integer input values
	  were not multiplied by 2. Also added a note that the provided
	  FPS will be multiplied by 2
	
2008-01-14 - xvidenc 7.5.9
	* Bugfix: wrong default output name used for video files.
	  Should be Xvid.avi and not H264.avi. This bug was
	  introduced due to code sharing with the h264enc script
	* Changed default (un)sharp mask/gaussian blur matrix to
	  luma & chroma 7x7 as it provides a better balance than
	  the 3x3 matrix.
	* Added a tip for the 'denoise3d' and 'hqdn3d' filters that
	  one can do only Spatial, only Temporal or Spatial and
	  Temporal filtering with these filters. Spatial-only
	  filtering is achieved by setting the last two values
	  to 0, Temporal-only filtering is achieved by setting
	  the first two values to 0. Spatial and Temporal filtering
	  is achieved by using all values.
	* Added support for adjusting the filter strength of the 'fspp'
	  postprocessing filter.
	* Added support for doubling the frame rate of the content
	  during the deinterlacing process with the 'yadif' and 'mcdeint'
	  filters.
	* Added support for interlacing progressive 100 fps PAL and
	  progressive 119.88 fps NTSC content.
	* Updated the FPS code. Added support for PAL/SECAM/NTSC Quad
	  (100 and 119.880 fps) and reordered the menu. Also disabled
	  frame rate selection when interlacing progressive content or
	  deinterlacing interlaced content with a deinterlace filter
	  which doubles the output frame rate. Both actions are mutually
	  exclusive with setting the output frame rate as the chosen
	  interlace/deinterlace process will take care of the fps.
	* Placed the interlace filters 'tinterlace' and 'phase' after
	  the harddup filter so that duplicate frames will never get
	  interlaced.
	* Renamed variables $pullup, $telecine, $cropping, $colorspace,
	  $ivtc_filter, $int_fps and $int_ofps to $ivtcfilter, $telecinefilter,
	  $cropfilter, $colorspacefilter, $ivtcfilt, $intfps and $intofps
	
	
2008-01-11 - xvidenc 7.5.8
	* Modifications to the output filename code. As of now, for
	  DVD encodings, xvidenc will scan the DVD for its title
	  and will set the default output filename according to
	  the title found on the DVD disc. If the DVD title is not
	  found, xvidenc defaults to the old method.
	* Bugfix: don't ask for colorspace conversion if the user
	  doesn't scale the content. Colorspace conversion only works
	  with the scale filter.
	* Bugfix: revert using local variables in the bits_per_pixel_func()
	  and bits_per_block_func() functions. Local variables don't
	  work when a function is called inside another one.
	* Bugfix: wrong variable used in the video_deblock_func()
	  function. Should be 'deblockfilter' instead of 'deblock'
	* Bugfix: wrong variable used in the video_denoise_func()
	  function. Should be 'denoisefilter' instead of 'denoise'
	* Added support for the 'unsharp' (un)sharp mask/gaussian
	  blur filter.
	* Some cleanups in the audio_resample_func() function
	* Added support for selecting the frame dropping mode of
	  the inverse telecine 'detc' filter.
	* Improvements to the DVD subtitle menu

2008-01-08 - xvidenc 7.5.7
	* Added support for yadif=2 deinterlacing mode which
	  skips spatial interlacing checking
	* Added support for interlacing of progressive content with
	  the 'tinterlace' filter combined with 'phase'. Note
	  that only 50 fps progressive PAL and 59.94 fps
	  progressive NTSC content is supported! When interlacing
	  such content, the frame rate will be dropped to 25 fps for
	  PAL and 29.97 fps for NTSC
	* Colorspace conversion does not work with deinterlacing
	  and interlacing filters so disable it if the user uses
	  some of these filters.
	* Use local variables inside the bits_per_pixel_func() and
	  bits_per_block_func() functions
	* Changed variables $scaler, $iss, $ss_parameters and
	  $accurate_vertical to $sws, $isws, $swsparam and $swsaccurate
	* Changed the order of the video filters. The softskip
	  filter should come after filters which need to see
	  duplicate or skipped frames in order to operate correctly.
	  This includes any filter that does temporal processing,
	  like the temporal denoiser, hqdn3d/denoise3d/ow and all
	  the inverse telecine filters. The softskip filter should
	  also come before scaling so that the scale filter will be
	  skipped if a frame is going to be dropped. Deinterlacing
	  or pullup should be done before cropping. The harddup filter
	  should be placed before the telecine one so that duplicate
	  frames will never get telecined, we don't want that. The
	  interlace filters should be placed after the softskip and
	  scale filters and before the harddup filter.
	* Improvements to the DVD chapters exporting code. The user
	  no longer needs to provide a path/filename to export the
	  chapters to disk. As of now, the path and filename are
	  automatically detected and set based on the provided output
	  file name and path for the encoding
	* Improved the chapters loading code for the MP4/MKV containers
	* Some modifications to the 'sed' parsing
	* Improved the MEncoder options exporting code
	* Updated the man page
	
2008-01-05 - xvidenc 7.5.6
	* Added support for the Motion Compensating Deinterlacer
	  (mcdeint) combined with Yadif
	* Renamed variable $interlaced to $interlacing
	* Disabled GMC in the UHQ preset and QPEL in the EHQ
	  preset
	* Added support for setting the audio volume gain
	  with the 'volume' filter
	* Disabled automatic scanning of input video files
	  to see if they hold up more than one video stream.
	  Some MPEG-TS files can cause troubles for xvidenc
	  which will enter into an endless loop when scanning
	  for multiple video streams
	* Updated the man page

2008-01-02 - xvidenc 7.5.5
	* Placed all video filters into one variable called
	  'videofilters'. Did the same for the audio filters
	  which are now carried by the single variable 'audiofilters'
	  This reduces filters maintenance cost for each pass
	* Added support for the new Overcomplete Wavelet Denoiser
	* Added support for the temporal chroma strength parameter
	  in the hqdn3d denoise filter
	* Added support for the older 3D denoise filter (denoise3d)
	* Added support for the Temporal Denoise filter (tn)
	* Added support for colorspace conversion during scaling
	* merged the $srate and $resample variables
	* Bugfix in the audio_volnorm_func() function
	* Small improvements to the fps detection code
	* Some cleanups/cosmetic changes
	
2007-12-22 - xvidenc 7.5.4
	* Changed contact email address
	* Added support for the spp, uspp, fspp and pp7
	  postprocessing deblock filters. This removes support
	  for the old 'pp' postprocessing filters and replaces
	  them with the new and more efficient ones. It also
	  fixes the nasty hack in the video_deinterlace_func()
	  function and removes code duplication for DVD and video
	  files in that function.
	* Removed variables $yadif and $kerndeint as they are
	  no longer required because of the changes above. All
	  deinterlacing filters are now carried by the $deintfilter
	  variable. Deblock/dering filters are carried by the
	  $deblock variable.
	* Added support for deringing/deblocking of DVDs. Although
	  not really useful for most DVDs, in some rare cases it
	  can be handy, like for custom made DVDs with a very
	  low bitrate and blocking artifacts.
	* Added support for denoising of input video files.
	* Video functions reordering.
	* Updated the README.xvidenc file.
	* Updated the man page.

2007-12-15 - xvidenc 7.5.3
	* Disabled asking for optimization of the MP4 file
	  layout if the user has chosen to embed subtitles
	  in the container. If optimization is ran on a
	  MP4 file with embedded subtitles, the subtitles
	  will all be black and unreadable
	* Bugfix: moved the MP4 output variable before the
	  optimization function as it is required by the
	  function but won't be detected if it comes after
	* Added a 'nice' value of 10 when remuxing to the
	  MKV and the MP4 containers
	* Merged the vobsubout and the vobsuboutindex variables
	
2007-12-14 - xvidenc 7.5.2
	* User request: add support for subtitles for input
	  video files. Useful if user wants to get the subtitles
	  from a VOB file on disk
	* Added support for importing ripped VobSub subtitles
	  into the Matroska and the MP4 container
	* Improved the chapters loading code. Now spaces in
	  file names are supported when importing a chapters file
	* Added -sc switch for sanity check. This will check for
	  the programs which are required for the correct operation
	  of the script and it will print the status in a list.
	  It will also display which audio codecs are supported
	  by MEncoder.
	* Some cleanups
	* Updated the man page
	* Updated the AUTHORS file
	
2007-12-01 - xvidenc 7.5.1
	* Added support for importing chapters information from
	  a file when remuxing into the MP4 container
	* Fixed default name of the output file when exporting
	  chapters info. Was 'h264chapters' due to code sharing
	  with the h264enc script. Sorry for the inconvenience
	* Added destination directory checking when exporting
	  DVD chapters to a file
	
2007-11-30 - xvidenc 7.5.0
	* Added support for exporting all chapters information
	  from a DVD to a file. This requires 'dvdxchap' from
	  'ogmtools'
	* Added support for importing chapters information
	  into the Matroska container when remuxing
	
2007-11-13 - xvidenc 7.4.9
	* Enabled MP2 audio for the MP4 container
	* DVD chapter improvements. Now each chapter is displayed
	  in a menu list together with its start position. This
	  requires MPlayer 1.0rc2 so upgrade to use this feature
	* Increased the crop scanning from 15 to 30 frames for
	  a better detection of the crop values
	* When exporting the MEncoder parameters to a file, if the
	  file already exists, do not overwrite it but just append
	  the new parameters to it
	* Cleanups and typo fixes
	
2007-10-05 - xvidenc 7.4.8
	* Added support for loading custom quantization matrices
	  when using quality presets (user request)
	
2007-08-31 - xvidenc 7.4.7
	* Disabled alias expansions in the shell, just in case it
	  might interfere with aliases in the .bashrc file
	* Added support for the FLAC audio codec (user request)
	* Changed the way the -o option operates (user request)
	* Updated the man page
	
2007-08-15 - xvidenc 7.4.6
	* Quality presets: enabled turbo mode for first pass in
	  2-pass encoding for all quality presets with the exception
	  of the NLQ preset
	* Removed the audio surround filter in AC3 since it's
	  not really useful and is only used on video files
	  with matrix encoded audio
	* Rewrote the audio_volnorm_func() function because of
	  the changes made to the audio filter chain
	* Added condition to check if any audio filters are used
	  so we can add the -af option to the MEncoder parameters
	* Added audio_channels_func() function for AC3, AAC, PCM
	  and COPY
	* Some small cleanups
	* Faster code to detect FPS values
	* FPS: now both fractions (for Progressive NTSC/NTSC) and integer
	  for (PAL/SECAM) are supported
	* Changed Megabyte to Mebibyte in video bitrate calculation
	
2007-08-08 - xvidenc 7.4.5
	* Added the harddup filter at the end of the filter chain
	  to further eliminate possible A/V sync problems when
	  muxing to the MKV and/or MP4 containers
	* Disabled the check_video_filters_func() function as it is
	  made obsolete by the harddup filter since this filter will
	  always be appended to the filter chain and the -vf option
	  will always be required even if no other filters are used
	* Added support for channel selection when using audio stream copy
	* Added support for encoding from a different DVD angle
	* Now video bitrate calculation for a target file size works with
	  audio stream copy
	* Disabled asking for telecine/inverse telecine if content is PAL/SECAM
	* Updated the man page
	
2007-08-05 - xvidenc 7.4.4
	* Squashed a bug in the fps condition checking code
	* Fixed a potential problem in the inverse telecine/pullup code
	  where A/V could get out of sync due to missing -fps 30000/1001
	  value
	* Enabled audio encoding for first pass in 2-pass mode.
	  After extensive testings, without audio encoding for the
	  first pass, MEncoder can break A/V sync, especially when
	  doing a inverse telecine/pullup process where frame dropping
	  and duplicate frames are involved.
	* Squashed a bug in the subtitle code which hardcoded the
	  subtitles into the movie even if user has selected to
	  dump them to files on disk
	* Added support for the DETC inverse telecine filter
	* Added warning notification if resolution width and/or
	  height is not divisible by 16 as compression will suffer
	* Moved the call to the check_video_filters_func() function
	  outside of the scaling section
	* Only ask for telecine/inverse telecine filters if user doesn't use
	  interlaced encoding as it is mutual exclusive with it
	
2007-07-30 - xvidenc 7.4.3
	* Added support for the Yadif deinterlacing filter
	* Added support for Donald Graft's adaptive kernel deinterlacing filter
	* Added support for Pulldown Reversal/Inverse Telecine. Please
	  read the FAQ at http://xvidenc.sourceforge.net on how and
	  when to use these filters! Currently 3 filters are supported,
	  the pullup, filmdint and ivtc filters
	* Added support for Hard Telecine/3:2 Pulldown. Again read the
	  FAQ on how and when to use it, if at all!
	* Reverted back to fractions for FPS values. According to
	  MPlayer's doc, integer/float should not be used anymore
	  with MEncoder. This change also updates the bits_per_pixel_func(),
	  bits_per_block_func() and keyframe variable
	* Due to the high versioning, as of this version, xvidenc will
	  continue to use a microversion. When I started writing the script,
	  I didn't think of going public with it so that's why versioning wasn't
	  important...
	* Updated the man page
	
2007-07-27 - xvidenc 7.4.2
	* Changed shell interpreter from /bin/sh to /bin/bash as there were some
	  problems reported by Ubuntu/Debian users. Sorry for the inconvenience
	
2007-07-26 - xvidenc 7.4.1
	* Merged the -bpp and -bpb options
	* Added bitrate calculation to the -bpp option which is based on
	  the bits per pixel value
	* Fixed a bug in the video bitrate calculation for a target file size.
	  If user has chosen to encode a video file which has more than one video
	  stream in it, and if the selected video stream for encoding is not the
	  first one, the calculated bitrate will be wrong as the $vid variable was
	  missing thus mplayer will get the length of the first video stream instead
	  of the stream selected by the user
	
2007-07-25 - xvidenc 7.4
	* Updated the AAC part of the audio resample function. In addition
	  to 48000 and 96000 Hertz, AAC also supports 64000 and 88200 Hertz
	* Some parenthesis changes
	* Added support for optimizing the MP4 file layout with mp4creator.
	  This is not a hard dependency! If mp4creator is missing, this
	  option will be skipped. xvidenc still uses MP4Box for MP4 muxing
	* Changed the output FPS format to integer and float
	* Updated the bits_per_pixel(), bits_per_block() and keyframe to support
	  the new integer/float FPS format
	* Disabled converting the final AVI to MKV if user has chosen to use the
	  AAC audio codec. I've spoken to Moritz Bunkus, the author of mkvmerge,
	  and he confirmed that at the moment he hasn't found a way yet to extract
	  the AAC headers from AVIs so for the time being, it is not possible to
	  convert AVIs with AAC audio to the Matroska container.
	* Added support for input video files which contain more than one video stream.
	  Note that cropping won't be auto-detected on any other stream except on the
	  first one (stream 0) as MPlayer seems to have issues with the -sstep option
	  and I still haven't got an answer from the developers on how to fix it
	* Converted the get_filesize_func() function from integer to float for more
	  accurate file size reportings
	* Updated the AUTHORS file
	* Updated the man page
	
2007-07-20 - xvidenc 7.3
	* Implemented user_interrupt_func() function for when the
	  user hits CTRL+C or CTRL+ALT+C
	* Added support for displaying the DVD disc title
	* Some improvements to the config directory code
	* Changed the default ABR AAC bitrate from 140 to 110 since
	  AAC is much more efficient
	* Implemented -bpp option for calculating the Bits Per Pixel values
	  Many thanks to Aymeric for the help on this one
	* Implemented -bpb option for calculating the Bits Per Block values
	* Updated the man page
	
2007-07-13 - xvidenc 7.2.1
	* Fixed a bug in the bits_per_block_func() function. The formula was
	  wrong which made this function display incorrect bpb values
	
2007-07-12 - xvidenc 7.2
	* Updated the MKV and MP4 container conversion code. Now user
	  can convert the AVI to both formats, not just only one of them
	* Added bits_per_block_func() function for calculating and displaying
	  how many bits are used for each 16x16 macroblock
	* Complete rewrite of the file splitting code. Removed the 702 MB
	  requirement before the split option kicks in. The new splitting
	  code is much more flexible now despite of its large size. Now if
	  user has chosen to convert the AVI to MKV or to MP4 or to both
	  formats, he can choose which formats to split
	* Updated the destination output checking code. Now this code respects
	  user permissions and warns the user and exits if creation of the
	  destination directory has failed
	* Added support for dumping subtitles to a file on disk
	* Added support for AAC object type complexity profiles
	* Updated the AUTHORS file
	* Updated the README.xvidenc file
	
2007-07-05 - xvidenc 7.1
	* Web site launched for xvidenc at http://xvidenc.sourceforge.net
	* Added support for converting AVIs to the MP4 format. This
	  only works with MP3/AAC audio or NOSOUND as MP4Box doesn't
	  support the other audio codecs
	* Added audio_codec_in_video_file_func() function to check
	  for MP3/AAC audio codecs in input video files so that user
	  can convert the final AVI to MP4 format if he wants to. This
	  function is only used when user decides to copy the audio
	  of the original input video file (no re-encoding)
	* Added bits_per_pixel_func() function to calculate and display
	  the BPP value based on video bitrate, width, height and FPS
	* Updated the disk space checking code to also check the
	  available size of the xvidenc config directory
	* Updated the file splitting code to support the MP4 format
	* Updated the man page
	
2007-07-04 - xvidenc 7.0
	* Added Near Lossless Quality (NLQ) preset. This preset is
	  supported only in fixed-quant mode!
	* Updated the man page
	
2007-07-01 - xvidenc 6.9
	* Added support for 96 kHz sampling for AAC audio to the
	  audio_resample_func() function
	* Added support for Multi-channel AAC audio encoding. Note that
	  this can introduce bitrate variations into the audio stream so
	  that video bitrate calculation for a target file size won't be
	  very accurate!
	* Added support for both MPEG formats supported by AAC audio
	  (MPEG2 and MPEG4)
	* Merged code of the WMAv1 and WMAv2 audio codecs into one
	* Updated the man page
	
2007-06-28 - xvidenc 6.8
	* Added support for the WMAv1 and WMAv2 audio codecs. Note that
	  this requires latest version of SVN MPlayer or MPlayer 1.0rc2
	  as previous MPlayer versions do not support encoding to the
	  above mentioned audio codecs.
	* Updated the man page and README.xvidenc file
	
2007-05-31 - xvidenc 6.7
	* Implemented '-p help' option for quick help on quality presets usage.
	  Now user can use 'xvidenc -p help' to get a quick help
	  on presets and how to use them.
	* Added one more quality preset (Normal Quality (NQ))
	* Removed obsolete checking for resolution format since
	  the $scale variable translates it to the correct
	  MEncoder format no matter if user uses a : or x for
	  the resolution
	* Added support for checking disk space left over in the destination output
	  directory. If < 4 GB then user will be warned that he's running out of
	  disk space in that location.
	* Decreased default difference threshold deblocking value for
	  video files to 70 as a too high value can smear details too much
	* Removed an extra "layer" of piping in variables. There's
	  no need to "cat" a file and then pipe the output to "grep"
	  to get a specific value from that file as "grep" can do
	  it by itself. No need to do $(cat /path/to/file/file_name | grep "value")
	  instead use $(grep "value" /path/to/file/file_name)
	* Small cosmetic changes
	* Updated the man page and fixed recommended quality presets. Recommended
	  presets should be 'vhq', 'ehq' and 'uhq' instead of 'mq' and 'hq'
	
2007-05-25 - xvidenc 6.6
	* Added options "rc_reaction_delay_factor" and "rc_averaging_period"
	  to the quality presets
	* Added informant display_quality_preset_func() function
	* Improved resolution code. Now if user has chosen to
	  crop the input source, default resolution value will
	  fall back to the visible resolution area after cropping,
	  (eg, the left over area of the resolution after removing
	  the black bands with the crop filter). If no cropping
	  selected, default resolution value will be the original
	  one from the input source
	* Added support for encoder priority settings ("nice" values)
	* Fixed a small bug in the cropping function that will fail if
	  user wants to crop a video file which contains spaces in its
	  file name
	* Updated the man page
	
2007-05-23 - xvidenc 6.5
	* Implemented 9 different video quality presets
	* Updated the man page
	
2007-05-22 - xvidenc 6.4

2007-03-20 - xvidenc 5.9
	* Added basic support for muxing the final AVI file into
	  Matroska container (requires mkvmerge)
	* Modified the splitting code to support the Matroska container
	* Updated the man page
	
2007-03-18 - xvidenc 5.8
	* Further improvements to the options saving code

2006-12-20 - xvidenc 4.0
	* Changed default output FPS format to float
	* Small overall improvements
	
2006-12-17 - xvidenc 3.9
	* Little code improvements for better error reporting
	
2006-12-14 - xvidenc 3.8
	* Fixed a bug in the MP3 filters config code where it won't work if
	  user has chosen to resample the audio (-af was missing - the bug
	  was introduced while fixing the code of the volnorm and resample filters)
	* Changed default AAC quality to 200
	* Updated the README.xvidenc file
	
2006-12-14 - xvidenc 3.7
