+%description
+h264enc is an advanced and powerful interactive menu-driven shell script written
+for the GNU/Linux operating system which can help you to encode a DVD, a video file,
+a directory with video files or a (S)VCD to the H.264/MPEG-4 Part 10/AVC video format
+using the MEncoder encoder from the MPlayer project and the libx264 library. It supports
+muxing the final encode from AVI to MKV, from AVI to OGM, from AVI to TS and from
+AVI to the MP4 container.

+%changelog
+* Wed Apr 09 2014 Grozdan Nikolov <neutrino8@gmail.com> 9.9.2
+	* Allow importing of mks (Matroska stream) subtitles into MKV. Such files
+	  are usually created when dumping subs with the GUI version of mkvmerge
+	* Add -nosub when importing external subtitles into MKV/MP4/OGM to prevent
+	  auto-loading of any embedded subs in the input file
+	* Use case statements to check the values of the $MAX_AMOUNT_AUD_TRACKS and
+	  $MAX_AMOUNT_SUBS variables
+	* Auto-cropping was not possible when input is Blu-ray due to missing bd
+	  param in the case statement
+	* Set default audio channels decode option to 6 when input is Blu-ray
+	
+* Tue Apr 08 2014 Grozdan Nikolov <neutrino8@gmail.com> 9.9.1
+	* Fixed not being able to calculate video bitrate for target file size
+	  when input is Blu-ray, due to missing $demuxer variable when calling
+	  MPlayer
+	* Fixed DVD scanning in the -scan option
+	* Support Blu-ray scanning in the -scan option
+	* Display in the -sc option if MEncoder has Blu-ray support
+	* Warn and exit if user chooses Blu-ray as input but MEncoder doesn't support it
+	* Placed the $device and $vid variables after the $MPLAYEROPTS one in order for
+	  the custom MPlayer options not to possibly overwrite these variables
+	* Modified the get_devices_func() function to allow files/folders as input
+	  so that a user can scan a DVD ISO or VIDEO_TS directory, not just discs
+	* Fixed the colorprim code. $device and $vid variables were missing when
+	  calling MPlayer to get the resolution height
+	  
+* Mon Apr 07 2014 Grozdan Nikolov <neutrino8@gmail.com> 9.9.0
+	* Initial, basic support for encoding from Blu-ray discs/ISOs/directories.
+	  Requires MPlayer to be compiled with libbluray. As libbluray doesn't
+	  support encrypted Blu-rays, it is not possible to encode such Blu-rays.
+	  Encryption must first be stripped before encoding with h264enc
+	* Reduced some duplication in the audio code for the first track for MKV
+	* Adjusted the vbv_maxrate and vbv_bufsize for the bd40 and bdhq40 presets
+	  to comply with the level limits
+	  
+* Sat Mar 29 2014 Grozdan Nikolov <neutrino8@gmail.com> 9.8.7
+	* Merged the neroaac/fdkaac part of the MP4Box code as they're identical
+	* Use a case statement to decide between --bluray and --avchd for tsMuxeR
+	* A few more function renaming to carry the _func at the end
+	
+* Fri Mar 28 2014 Grozdan Nikolov <neutrino8@gmail.com> 9.8.6
+	* Fix a syntax error
+	
+* Fri Mar 28 2014 Grozdan Nikolov <neutrino8@gmail.com> 9.8.5
+	* Use a single variable for keyint for the Blu-ray/AVCHD presets. Reduces a bit of duplication
+	* Reduced some duplication in the check_audio_codec_func() function by moving some of
+	  the error messages into a new audio_codec_exit_func() function
+	* Allow muxing to TS when using neroAacEnc and/or FDKAAC in LC-AAC mode
+	* Merged the NEROAAC/FDKAAC parts in the mkvmerge code as they're identical, thus we
+	  reduce a bit of duplication
+	* Updated the man page
+	
+* Mon Mar 24 2014 Grozdan Nikolov <neutrino8@gmail.com> 9.8.4
+	* Add audio encoder info to the MKV global tags
+	* Renamed the mencoder_opts() function to mencoder_opts_func() for consistency reasons
+	* Fixed subtitles metadata info in the MKV global tags
+	
+* Sun Mar 23 2014 Grozdan Nikolov <neutrino8@gmail.com> 9.8.3
+	* Bugfix: If using nosound and dumping subsequent subs, the audio option
+	  for MEncoder was set to -ao null which is not recognized by MEncoder.
+	  Change it to -nosound instead
+	  
+* Sat Mar 22 2014 Grozdan Nikolov <neutrino8@gmail.com> 9.8.2
+	* Bugfix: for subsequent audio tracks, when using neroAacEnc as encoder,
+	  the value of --aac-is-sbr used for HE-AAC by mkvmerge was set to 1:1. It
+	  should be 0:1
+	* Use the AACTYPE variable instead of the aacprof variable to check which
+	  type of AAC the user wants in the neroaac_audio_func() function
+	* In VBR mode for audio encoders that support it, indicate which values
+	  result in better quality, ie based on the encoder a lower value results
+	  in higher quality or the reverse
+	  
+* Fri Mar 21 2014 Grozdan Nikolov <neutrino8@gmail.com> 9.8.1
+	* Set the default crop rounding value to 4 for more accurate cropping
+	* Initial support for the FDK AAC audio encoder. Requires latest git from
+	  https://github.com/mstorsjo/fdk-aac/commits/read-streamed-wav
+	  
+* Thu Feb 13 2014 Grozdan Nikolov <neutrino8@gmail.com> 9.8.0
+	* Bugfix: dumping subs did not work when input is a VIDEO_TS DVD folder.
+	  Patch by Harry Gunnarsson
+	  
+* Sun Feb 02 2014 Grozdan Nikolov <neutrino8@gmail.com> 9.7.9

+	  auto-loading of any embedded subtitles in the input
+	* Use -ao null instead of -nosound
+	
+* Sat Jan 18 2014 Grozdan Nikolov <neutrino8@gmail.com> 9.7.8
+	* New variable in the config file, DELETE_AVI_AFTER_REMUX, to automatically delete

+	  and fixes encoding from a named pipe
+	  
+* Sun Oct 20 2013 Grozdan Nikolov <neutrino8@gmail.com> 9.6.1
+	* Added support for encoding to 640 kbps AC3 audio
+	
+* Tue Jul 02 2013 Grozdan Nikolov <neutrino8@gmail.com> 9.6.0
+	* Fix audio TID for MKV when using neroAacEnc as encoder

+	* Add fake_interlaced to the AVCHD presets
+	
+* Mon Jun 10 2013 Grozdan Nikolov <neutrino8@gmail.com> 9.5.7
+	* Add fake_interlaced flag to 25fps/29.970fps content when using the Blu-ray presets. It allows
+	  to encode progressive 25p and 30p content but flags it as interlaced for Blu-ray compliance

+	
+* Sat Jun 08 2013 Grozdan Nikolov <neutrino8@gmail.com> 9.5.5
+	* Enable weightp for the Blu-ray/AVCHD HQ presets. In order to have a broader compatibility
+	  with older Blu-ray players (mostly ones with buggy MediaTek chips), weightp is set to 1 and not 2
+	* Set VBV maxrate to 40000 and VBV buffer to 30000 for the Blu-ray presets
+	* Set color primaries, transfer characteristics and matrix coeffs to bt709 for the Blu-ray/AVCHD presets

+	* Removed workarounds for older MP4Box versions. As of this release, only gpac 0.5.0 and higher
+	  is supported. SVN version is highly recommended, though
+	* Improved AC3 and MP3 audio handling
+	* Removed turbo option. It is no longer needed
+	* When using AC3 audio, language TID for MKV was set to 1. It should be 0
+	
+* Tue May 28 2013 Grozdan Nikolov <neutrino8@gmail.com> 9.5.2
+	* Fix OGM muxing with AC3 audio
+	
+* Tue May 28 2013 Grozdan Nikolov <neutrino8@gmail.com> 9.5.1
+	* Use aften for AC3 audio encoding as MEncoder is currently broken. This bumps up the config
+	  file version to 22
+	  
+* Tue May 21 2013 Grozdan Nikolov <neutrino8@gmail.com> 9.5.0
+	* Bugfix: add missing 384 kbps option for AC3 audio
+	* Notify the user when we first create the config file
+	* SAR is Sample Aspect Ratio, not Storage Aspect Ratio. Corrected this mistake
+	
+* Thu Apr 11 2013 Grozdan Nikolov <neutrino8@gmail.com> 9.4.9
+	* Use ffmpeg's MPEG12 decoder instead of the libmpeg12 one
+	
+* Mon Oct 01 2012 Grozdan Nikolov <neutrino8@gmail.com> 9.4.8
+	* Added bluray_compat=1 parameter to the Blu-ray and AVCHD presets
+	* Use 'true' instead of 'false' where appropriate
+	* Updated the man page
+	
+* Wed Sep 26 2012 Grozdan Nikolov <neutrino8@gmail.com> 9.4.7
+	* Change bad default bitrate value in DTS audio encoding to 384kbps.
+	
+* Mon Apr 16 2012 Grozdan Nikolov <neutrino8@gmail.com> 9.4.6
+	* Bugfix: FAAC encoding was using wrong language TID in mkvmerge. Should be 0 instead of 1 as
+	  we no longer encapsulate AAC in MP4
+	* Removed --no-chapters mkvmerge option for FAAC encoding. It's no longer needed as we no longer
+	  store the AAC audio in MP4 container
+	  
+* Sat Apr 07 2012 Grozdan Nikolov <neutrino8@gmail.com> 9.4.5
+	* Don't require FAAC to be compiled with MP4 container support (the -w option). Some distro's
+	  do not compile FAAC with MP4 support so play it safe and assume FAAC isn't compiled with
+	  MP4 support
+	  
+* Tue Feb 21 2012 Grozdan Nikolov <neutrino8@gmail.com> 9.4.4
+	* Only 'sed' mbtree for multi-pass mode
+	* Don't append "- chapter [id]" to output file when encoding only specific chapters
+	
+* Tue Jan 03 2012 Grozdan Nikolov <neutrino8@gmail.com> 9.4.3
+	* Use -vc dummy in MPlayer in the audio code. Seems to work better on some files
+	
+* Sun Jan 01 2012 Grozdan Nikolov <neutrino8@gmail.com> 9.4.2
+	* Use a separate variable in config file for setting the default CRF or QP value (DEFAULT_VID_CRFQP).
+	  This bumps the config file version to 21
+	* Renamed the DEFOUTPUT, DEFPATH and DEFBATCHDIR variables to DEFAULT_OUTPUT, DEFAULT_PATH and
+	  DEFAULT_BATCHDIR
+	* Be slightly more portable by using #!/usr/bin/env bash instead of #!/bin/bash shebang
+	* Replaced some if conditionals in the -sc option by using 'test' directly
+	* Added an option for passing additional MEncoder parameters. Useful for when the user wants to
+	  use something like -mc 0 -noskip, for example
+	* Added support for encoding to DTS audio through the dcaenc encoder which can be found at
+	  http://aepatrakov.narod.ru/dcaenc/
+	* Minor changes to the video_delogo_func() function. Use $sourcetype, $device, $vid and
+	  $MPLAYEROPTS variables. Also use -nosound in MPlayer
+	* Improved the mkvtags file. Escape special characters like &, <, > and " in the Title field
+	
+* Mon Oct 10 2011 Grozdan Nikolov <neutrino8@gmail.com> 9.4.1
+	* Introduced two new variables in the config file, DEFAULT_VID_BITRATE and DEFAULT_AUD_CODEC.
+	  The first one sets the default video bitrate or CRF/QP value while the second one can
+	  be used to set a default audio codec. This change updates the config file to version 20
+	* Fixed a typo in man page
+	
+* Sun Aug 20 2011 Grozdan Nikolov <neutrino8@gmail.com> 9.4.0
+	* Disable mbtree in multipass mode to prevent segfaulting MEncoder due to differences in
+	  frames amount in the passlog file. Disabling mbtree reduces quality but saves us a crash
+	  in MEncoder
+	* Notify the user that the script does not support AAC in AVI anymore. Also exit if user
+	  has not selected any of the other supported containers
+	  
+* Mon Aug 08 2011 Grozdan Nikolov <neutrino8@gmail.com> 9.3.9
+	* Bugfix: selecting the x264 internal denoiser does nothing due to missing $nr variable
+	  in the MEncoder options
+	  
+* Sat Jul 23 2011 Grozdan Nikolov <neutrino8@gmail.com> 9.3.8
+	* Update the mq, nq, hq, vhq, ehq, uhq and ihq presets. Increase subme by 1. For the ihq
+	  preset, this means that it uses subme 11 now which requires latest x264 from git
+	  
+* Sun May 15 2011 Grozdan Nikolov <neutrino8@gmail.com> 9.3.7
+	* Removed the ssim and psnr options from the presets. Should only be used for benchmarking
+	
+* Sun Apr 04 2011 Grozdan Nikolov <neutrino8@gmail.com> 9.3.6
+	* Fixed the subtitles function which got broken when the get_selection_func()
+	  function got introduced
+	  
+* Tue Mar 29 2011 Grozdan Nikolov <neutrino8@gmail.com> 9.3.5
+	* Added support for setting the crop rounding value
+	
+* Wed Mar 09 2011 Grozdan Nikolov <neutrino8@gmail.com> 9.3.4
+	* Fix option 4 and 5 of the video_deblock_func() function. Wrong vars used
+	
+* Mon Feb 21 2011 Grozdan Nikolov <neutrino8@gmail.com> 9.3.3
+	* Fixed a bug in directory batch mode were wrong conditional was used to check
+	  for the DEFOUTPUT variable
+	* Display which file is currently being processed in batch mode
+	* Check only for files while in batch mode
+	* Do not exit if user types an incorrect answer to y/n questions. Instead, ask
+	  the question again. Patch by Jan-Hendrik Peters and friends
+	  
+* Sat Jan 08 2011 Grozdan Nikolov <neutrino8@gmail.com> 9.3.2
+	* Use -demuxer lavf when trying to get the video length for bitrate calculation
+	  for a target file size. Should be more reliable on M2TS/TS files
+	* Add support for the delogo filter. Patch by Haiko Michelfeit <haiko AT zsyndikat DOT org>
+	  Config file version is bumped to 19
+	* Updated copyright dates
+	
+* Sun Dec 05 2010 Grozdan Nikolov <neutrino8@gmail.com> 9.3.1
+	* Fix for the custom preset (cp) option
+	
+* Fri Nov 26 2010 Grozdan Nikolov <neutrino8@gmail.com> 9.3.0
+	* Remove double $HOME variable in the -scan option
+	
+* Fri Oct 29 2010 Grozdan Nikolov <neutrino8@gmail.com> 9.2.9
+	* Fix typo in the backup_file_func(): exisiting -> existing
+	* Workaround multichan FAAC encoding. FAAC somehow does not like multichan PCM from
+	  MPlayer but it does if one treats it as raw using -P in FAAC. Nero/FLAC/Vorbis have
+	  no issues, though. Go figure
+	* Added support for setting subtitle codepage during hardcoding of external subs
+	* Added support for the audio equalizer filter. This updates the config file version
+	  to 18
+	* Removed 'time' requirement
+	
+* Thu Sep 16 2010 Grozdan Nikolov <neutrino8@gmail.com> 9.2.8
+	* Workaround mencoder stupidity. With recent versions of mencoder that have subs
+	  enabled by default (who came up with that great idea?), in case the user selects
+	  to dump a sub for importing into mkv/mp4, during multipass encoding the first sub
+	  will always get hardcoded due to missing -nosub option in the 2nd and 3rd pass code.
+	  This is only valid for multipass encodes so people using one pass modes (-1p, -qp or -crf)
+	  are safe.
+	  
+* Wed Sep 15 2010 Grozdan Nikolov <neutrino8@gmail.com> 9.2.7
+	* Small update to the -scan option. Just check if input file is there, regardless if
+	  user provides the full path or not
+	* Enable trellis in some presets that use CAVLC
+	
+* Mon Aug 23 2010 Grozdan Nikolov <neutrino8@gmail.com> 9.2.6
+	* Fixed a syntax error in the iphq preset
+	
+* Sun Aug 22 2010 Grozdan Nikolov <neutrino8@gmail.com> 9.2.5
+	* Update QuickTime & iPhone presets. Patch by gongloo
+	
+* Wed Jul 21 2010 Grozdan Nikolov <neutrino8@gmail.com> 9.2.4
+	* Typo fix in the display_quality_preset_func(); verslow -> veryslow. As this is an
+	  informative function, it does not affect the encoding configuration
+	* Force -nosub option in case subtitles are skipped. This is to prevent auto-loading
+	  of subs
+	  
+* Fri Jun 25 2010 Grozdan Nikolov <neutrino8@gmail.com> 9.2.3
+	* Added support for x264's preset, tune and profile options. This adds two additional
+	  optional args [-t (for tune) and -pf (for profile)] which can only be used with an
+	  x264 preset, not with the built-in script presets. If used with those, these args
+	  will be ignored.
+	  Examples on how to use x264 presets (which is also explained in the -help option)
+	  h264enc -crf -p slow
+	  h264enc -crf -p slow -t film
+	  h264enc -crf -p slow -pf main
+	  h264enc -crf -p slow -t film -pf high
+	  One can also switch the -t and -pf options, eg: h264enc -crf -p slow -pf high -t film
+	* Updated the man page
+	
+* Sat May 15 2010 Grozdan Nikolov <neutrino8@gmail.com> 9.2.2
+	* Small bugfix in the get_devices_func() function; script exits when user hits enter
+	  to accept default device
+	* Remove AVI menu entry as supported container when using FAAC for audio encoding
+	
+* Thu Apr 29 2010 Grozdan Nikolov <neutrino8@gmail.com> 9.2.1
+	* Reworked a bit the audio channels decode/output function. This function also got
+	  renamed from audio_channels_func() to audio_channels_decode_func()
+	* Added support for the audio channels filter which can be used to add/remove/route channels
+	  This updates the config file to version 17 and adds variable ALLOW_AUD_CHANNELS
+	* Bugfix: audio filters were not inserted when doing 1-pass encodes
+	
+* Sat Apr 24 2010 Grozdan Nikolov <neutrino8@gmail.com> 9.2.0
+	* Switch to using external FAAC encoder to work around an issue in mkvmerge where
+	  it flags AAC audio taken from an AVI as being Main profile regardless if LC profile
+	  is used for encoding or not. Problem noticed & reported by benpro. This updates the
+	  config file to version 16 and requires FAAC to be installed.
+	* Same small cleanups
+	* Updated the man page
+	
+* Sun Mar 28 2010 Grozdan Nikolov <neutrino8@gmail.com> 9.1.9
+	* Replaced sed with awk for checking available disk space. Should work better on
+	  FreeBSD systems. Patch by ennob from doom9
+	* Updated interlace options and presets to support the latest x264 from git. Note
+	  that due to these changes, h264enc's presets are incompatible with older x264
+	  versions so please upgrade to latest x264 from git!
+	* Small update to the preset.cfg file
+	
+* Thu Mar 18 2010 Grozdan Nikolov <neutrino8@gmail.com> 9.1.8
+	* Small bugfix: keyint and keyint_min weren't passed on to MEncoder when using some
+	  presets
+
+* Tue Mar 16 2010 Grozdan Nikolov <neutrino8@gmail.com> 9.1.7
+	* Space escaped some previously missed variables
+	* Use one variable in the presets (x264params) for all MEncoder x264 encoding options.
+	  Reduces some code and simplifies things a bit
+	* Updated the preset.cfg file to support the "one variable for all x264 encoder opts"
+	  Note: those using custom preset files for encoding should read the preset.cfg file
+	  in the doc dir and adapt their existing preset files to be compatible with the
+	  changes. Previous older custom presets written by users will not work with this and
+	  future versions of h264enc!
+	  
+* Thu Feb 18 2010 Grozdan Nikolov <neutrino8@gmail.com> 9.1.6
+	* Added new veriable 'DEFOUTPUT' to the config file which can be used to set a default
+	  output directory. This updates the config to version 15
+	* Modified the set_output_filename_func() function to support the above variable.
+		- If the DEFOUTPUT variable is empty, user can either provide just the output
+		  name for the encode (in this case the script assumes $HOME as output dir), or
+		  the full path and output name, which in this case the script will create the
+		  output dir if it's not present or will do a write test when the dir is present
+		  to see if it's writable by the user. If creation of output dir or the write test
+		  fails, the script exits with a notice.
+		- If the DEFOUTPUT variable contains a custom output dir, the script will test for
+		  it and create it if it's not present. If creation fails, the script exits with a
+		  notice. If the dir is present, the script will do a write test to see if the
+		  custom dir is writable. If not, the script exits with a notice.
+		- The DEFOUTPUT variable can be overwritten on the command line. This means that if
+		  user has set a custom output dir in the DEFOUTPUT variable but provides a path when
+		  asked on the command line, that path will be used instead of the one in the DEFOUTPUT
+		  variable. The script then will either check and create the provided output dir on
+		  the command line (if that dir is not present) or will do a write test if the dir
+		  is present. Upon failure of creation or write test, the script exits with a notice.
+		  If no path is provided on the command line but only the output name for the encode,
+		  the script will use the one set in the DEFOUTPUT variable.

+* Sat Jan 30 2010 Grozdan Nikolov <neutrino8@gmail.com> 9.1.5
+	* Reduced duplication in the audio encode exporting code by moving it inside functions
+	* Reduced duplication in the MKV/MP4/TS/OGM exporting code by moving it inside functions
+	* Reduced duplication in the code that prints some information before encoding starts
+	* Various minor code improvements
+	
+* Thu Jan 21 2010 Grozdan Nikolov <neutrino8@gmail.com> 9.1.4
+	* Set default H.264 level to 'auto' and also accept integer numbers as levels in addition
+	  to accepting fixed point ones, ie both 41 and 4.1 are now accepted as valid levels
+	* Renamed the rmconf() function to rmtemp() 
+	* Moved creation of temp dir, the interrupt_func() and rmtemp() functions at the beginning
+	  of the script
+	* Fixed a bug in the DVD part of the -scan option where lsdvd doesn't get a valid device
+	  passed. Bug was introduced due to changes in the new get_devices_func() function
+	* Reduced duplication in the mencoder_opts() function
+	* Various small code improvements
+	
+* Tue Jan 19 2010 Grozdan Nikolov <neutrino8@gmail.com> 9.1.3
+	* Made the TEMPDIR variable escape spaces in directory names
+	* Small update to the mkvtags_func() function
+	* Removed the -a52drc option for AC3 encoding
+	* Added new x264 intra_refresh option to the script and the preset.cfg file
+	* Added two new variables, DVD_DEVICE and CDROM_DEVICE, to the config file where user
+	  can set a default block device to encode from. This updates the config file to version 14
+	* Merged the get_dvd_devices_func() and get_vcd_devices_func() functions into a new one
+	  called get_devices_func()
+	  
+* Wed Dec 23 2009 Grozdan Nikolov <neutrino8@gmail.com>
+	* Fixed a severe bug that can cause in some cases severe data loss when using a 
+	  custom temp directory. It manifests itself when using a 'top' directory as custom
+	  temp directory such as a partition mount point or even the user's home directory.
+	  In such cases, the top directory will be deleted upon script termination or when encoding
+	  finishes, resulting in possible massive data loss due to rm -rf $TEMPDIR if TEMPDIR was
+	  set to, for example, /home/username or points to a mount point or another directory that
+	  may be important to the user.
+	  From now on, always use a job<pid> directory inside the one set in the TEMPDIR variable
+	  so it'll only delete the job<pid> directory and not its parent one, minimizing possibility
+	  of a data loss disaster
+	* Set nomixed_refs for the iphq/iphhq presets
+	
+* Thu Dec 10 2009 Grozdan Nikolov <neutrino8@gmail.com>
+	* Disabled weightp for the AppleTV presets
+	* Added new option sliced_threads present in latest x264 from git
+	* Enabled b_pyramid for some presets that use mbtree as it now works with mbtree
+	* Updated the preset.cfg file. Added sliced_threads option
+	* Changed all video ALLOW_* variables in the config file to ALLOW_VID_*
+	* When using dd to dump a DVD to an ISO, use options noerror,sync and a bs size of 2048
+	* Added support for sending mails. This requires the 'mailx' program and a valid .mailrc
+	  file in the home directory. Mail notification can be enabled in the config file of
+	  h264enc which also offers an example of a gmail setting for .mailrc
+	* Bumped config file version to 13
+	* Updated copyright dates
+	
+* Mon Nov 09 2009 Grozdan Nikolov <neutrino8@gmail.com>
+	* Implemented a simple telecine detector for NTSC DVDs. Currently it's a dumb solution
+	  which can't distinguish between hard telecine and interlacing but it's enough to
+	  detect soft telecine and mixed progressive/telecine content which is more common
+	* Simplified the FPS detection code
+	* Update to all presets: added new weightp x264 option. This requires latest x264
+	  revision from git
+	* Updated the preset.cfg file. Added weightp option
+	* Small general code improvements and cosmetics
+	
+* Wed Nov 04 2009 Grozdan Nikolov <neutrino8@gmail.com>
+	* Replaced a few if conditionals with case statements in the neroaac_audio_func() function
+	* Sed a comma at the end of resolution detection in case we're dealing with TS files. The
+	  default TS demuxer in MPlayer has a comma at the end of the resolution info which results
+	  in errorneous behavior in the bc calculation
+	* Simplified the resolution detection code
+	* Some small cleanups
+	
+* Mon Oct 19 2009 Grozdan Nikolov <neutrino8@gmail.com>
+	* Force stereo audio for Nero HE-AACv2 as it doesn't support anything else, thus
+	  it results in failure if user tries to encode with more than two channels. This
+	  updates the audio_channels_func() function and also adds a small new independent
+	  one called neroaac_hev2_func() which only sets the channels to two if the channels
+	  array variables are empty, as is the case when the user did not set the channels
+	* Small improvements to the ABR/VBR default audio bitrates for the neroAacEnc encoder.
+	  Base the default bitrates on the chosen AAC profile, i.e. if user chooses HE-AACv1,
+	  default bitrate will be 55 kbps or in case of quality-based VBR encoding a value of
+	  0.22. For LC-AAC and HE-AACv2, default bitrates and quality values will be 96 kbps
+	  or 0.35 and 25 kbps or 0.11, respectively. Note that this assumes the input audio is
+	  stereo so if it's anything else than that, it's up to the user to decide on bitrates
+	  or quality values
+	* Set default to a capital letter in questions where one needs to answer with y or n
+	* Update to all presets: updated the b_pyramid option to use the new args none/strict/normal
+	  present in latest x264 revision. Note that this requires both latest MPlayer from SVN
+	  and latest x264 revision from git
+	* Small b_pyramid update to the preset.cfg file
+	
+* Sat Oct 17 2009 Grozdan Nikolov <neutrino8@gmail.com>
+	* Added new function video_subtitles_align_func() for subtitle alignment control.
+	  Requested by blaz on doom9.org forum.
+	* Added new x264 option 'constrained_intra' to the preset.cfg file.
+	* Added detection of VFR content (1000 fps as reported by MPlayer).
+	* Added X264_VERSION and MKVMERGE_VERSION entries to the mkvtags_func() function.
+	* Simplified a bit the audio exporting code for the first track.
+	
+* Thu Sep 24 2009 Grozdan Nikolov <neutrino8@gmail.com>
+	* MP3 (MPEG1 Layer 3) only supports sample frequencies of 32, 44.1 and 48 kHz
+	  so restrict to those only in the audio_resample_func() function
+	* Set default for the pp7 deblocker to 3
+	* Fixed example typo in the DVD chapters code
+	* Insert the ilpack filter before the scaler to correctly align chroma channels
+	  when preserving interlacing
+	* Added AUDIO_CODEC_TRACK[1|2|3], AUDIO_LANGUAGE_TRACK[1|2|3] and H264ENC_PARAMETERS
+	  entries to the mkvtags_func() function
+	* Enabled adaptive transform for the AppleTV HQ preset (atvhq)
+	* Improved checking the availability of block devices
+	* Added option 'global_header' to the preset.cfg file
+	
+* Wed Sep 16 2009 Grozdan Nikolov <neutrino8@gmail.com>
+	* Small bugfix: setting the H.264 level for the fghq preset wasn't possible
+	* Small bugfix: the counter in set_output_filename_func() didn't increase itself
+	* Added SOURCE, VIDEO_FILTERS, AUDIO_FILTERS_TRACK[1|2|3], ENCODER and X264_PARAMETERS
+	  entries to the mkvtags_func() function
+	  
+* Mon Sep 14 2009 Grozdan Nikolov <neutrino8@gmail.com>
+	* Use only lowercase words in all case statements that deal with the input source
+	* Some small improvements to the exit info in the audio code
+	* Placed the -passlogfile option inside the PASSLOG variable
+	* Set psy_rd to 0.3 for the Anime presets
+	* Allow setting the H.264 level for the PC presets to "auto" so libx264 will
+	  decide itself which level to use based on options and resolution used
+	* Added support for 2-pass Nero AAC audio encoding. Note that 2-pass is only
+	  supported by ABR/CBR encoding and ensures that the output quality is constant
+	  (like VBR) while also ensuring that a specified output bitrate is achieved
+	  (like CBR). Requested by punlo on doom9.org
+	  
+* Sun Sep 06 2009 Grozdan Nikolov <neutrino8@gmail.com>
+	* Fixed a typo in the man page, MEnocder -> MEncoder
+	* Small improvement to how the MKV XML tagging file gets exported. Also improved
+	  the XML formatting and added COMMENT string with text "Tagged by h264enc $version"
+	* Added comment tag for MP4 and OGM with the same text as above
+	* Small update to the video_deinterlace_func() function's menu
+	* Add comment header with dates to batch files
+	
+* Fri Sep 04 2009 Grozdan Nikolov <neutrino8@gmail.com>
+	* Added new option sync_lookahead available in latest x264 git and updated the
+	  preset.cfg file
+	* Added support for the noise video filter. This change updates the config file
+	  to version 12. Also, encoding priority now defaults to a nice value of 10 in
+	  the config file
+	* Moved out the code which checks and backups/renames a file if it has the same
+	  name as the output provided by the user to a separate function called
+	  backup_file_func() and also improved it so that if there's already an existing
+	  backup file, the new one will increase its count number by one thus there's no
+	  more overwriting being done anymore. The same thing applies to existing chapter
+	  files and DVD subs
+	* Added support for Year and Genre metadata tagging for the MKV/MP4/OGM containers.
+	  For MKV, the genre and year is set globally using an automatically generated XML
+	  file. MP4 uses the iTunes tagging and OGM the comment space
+	* Updated the man page
+	
+* Tue Sep 01 2009 Grozdan Nikolov <neutrino8@gmail.com>
+	* Simplified the audio_channels_func() function a bit
+	* Merged the QP and CRF settings
+	* Increased rc_lookahead a bit for the ehq, uhq and ihq presets
+	* Improved detection of DVD audio language codes. We now specifically grep for the
+	  language word and then print the 2nd positional which gives us the language code.
+	  It works more reliably if the DVD does not report its language code for the audio track(s)
+	  so if this is the case, we fall back to undefined language. The previous code fails in
+	  such cases due to the printing of the 8th positional which will print the "aid:" part when
+	  there's no language code after the "language:" word, resulting in MKV/MP4 muxing failures.
+	  Reported by WalterK from doom9.org
+	* Moved the code that deals with DVD subs/cover files/metadata info/chapters and external
+	  subs for the MP4 container before its audio code
+	* Added slicing to the Blu-ray and AVCHD presets. It increases compliancy with the Blu-ray
+	  specs. Slicing is only available in the latest x264 from git so please upgrade if you
+	  intend to use the Blu-ray/AVCHD presets
+	* Added new options 'slices', 'slice_max_size' and 'slice_max_mbs' to the preset.cfg file
+	* Fixed chapters import for the OGM container. Missing '@' before the chapters input file
+	  results in the file not being imported
+	* Added support for audio language metadata info for the OGM container
+	* Small improvements to how chapters information is added to the output file name
+	
+* Sat Aug 15 2009 Grozdan Nikolov <neutrino8@gmail.com>
+	* Renamed presets f9 and f9hq to fl and flhq
+	* Added new preset 'fghq' specifically optimized for preserving film grain
+	* Removed duplicate videofilters variable. This removes the check for the tfields filter
+	  as now deinterlacing will always be done after cropping (which also speeds up things a bit)
+	  so the crop filter will never complain about crop area being outside of the original if
+	  tfields is used. It also reduces filters maintenance a bit
+	* Turn soft-clipping on in the volume audio filter
+	* Use aq_mode=1 for presets that have mbtree enabled as it usually does better on fades than
+	  aq_mode=2
+	* Updated the man page
+	
+* Tue Aug 11 2009 Grozdan Nikolov <neutrino8@gmail.com>
+	* Reduced the amount of if conditional iterations for setting the scaler interlace variable
+	* Print full path of the output file(s) at the end of encoding
+	* 10L: forgot to enable MB tree for the anihq preset
+	* Replaced variable CONFIGDIR with TEMPDIR. This change updates the config file to version 11
+	* Fixed some spacings issues by moving around some echo's
+	* Simplified the sample encoding code. Reduced some code duplication
+	* Upped psy_rd from 0.6 to 0.8
+	
+* Fri Aug 07 2009 Grozdan Nikolov <neutrino8@gmail.com>
+	* Added support for the audio panning filter. This change also updates the config file
+	  to version 10
+	* Simplifications to the audio_filters_func() and audio_filters_var_func() functions
+	* Moved the audio filters functions after the audio codec ones
+	* Fixed a bug in the audio_channels_func() function for the AAC codec. If user just
+	  hits return to accept the default AAC codec, the channels function was not called
+	  due to missing "" in the first case statement of that function
+	* Enabled MB tree (macroblock tree ratecontrol) for the high quality presets and disabled
+	  b_pyramid for presets that have mbtree enabled as it currently doesn't support it. Note that
+	  mbtree produces a large passlog file when ran in 2-pass mode but can increase quality anywhere
+	  between 2-70%, depending on the content. mbtree is only available in latest x264 git so
+	  please upgrade
+	* Added new options mbtree, rc_lookahead and nopsy to the preset.cfg file
+	
+* Sat Aug 01 2009 Grozdan Nikolov <neutrino8@gmail.com>
+	* Added new option -mfr which calculates the maximum allowed frame references within DPB
+	  (Decoded Picture Buffer) limits for different H.264 levels and resolutions
+	* Call the track_echo_func() function inside the select_audio_codec_func() one. Removes
+	  pointless duplication
+	* Don't call mplayer twice in the 2nd/3rd audio track code just to get the audio codec.
+	  Also removed a pointless case statement
+	* Allow users to set the H.264 level when using the standard PC presets
+	* Fixed a few typos in the preset.cfg file
+	* Updated the man page
+	
+* Thu Jul 30 2009 Grozdan Nikolov <neutrino8@gmail.com>
+	* Increased subq to 10 (QP-RD) for the IHQ preset. Requires latest x264 from git. Also
+	  lowered frameref from 16 to 8 and bframes from 10 to 7
+	* Add example on how to encode only specific DVD chapters. Some people keep bugging me
+	  about this while it's actually very simple
+	  
+* Fri Jul 24 2009 Grozdan Nikolov <neutrino8@gmail.com>
+	* Switched to the new Auto-variance AQ (aq_mode=2) for all presets. This requires latest x264
+	  revision from git so please upgrade!
+	* Decreased frame references for all iPod presets to 1 and increased subq to 8 for the HQ iPod
+	  presets
+	* Minor improvments to the set_output_filename_func() function
+	* Merged the audio code of the portable device presets. Moderately reduces code duplication in
+	  the audio functions calling code
+	* Added two new presets (ag1 and ag1hq) for Android G1 devices. This brings the total presets
+	  count to 60
+	* Added support for the new gradfun debanding video filter. Although mostly recommended for playback
+	  due to the fact that encoding tends to bring back banding, it can be useful to deband input
+	  sources which show pretty bad and very noticable banding effects before passing the content
+	  to the encoder. The gradfun filter is only available in MPlayer SVN. This also adds a new
+	  variable ALLOW_DEBAND to the config file where one can enable or disable this filter
+	* Added a small while loop to the video_crop_func() function which will keep asking the user for
+	  new crop values until he's satisfied with them. Patch by elektronaut from Doom9.org
+	* Added a new variable PRIORITY to the config file which can be used to set a global priority
+	  nice value for the encoding process. The values one can use are between (and including)
+	  -20 and 19. However, if the script detects that the variable has a negative nice value
+	  set and the script is being executed with regular user privileges, it will print a notice
+	  and exit. This change updates the config file to version 9
+	* Updated the man page
+	
+* Wed Jul 08 2009 Grozdan Nikolov <neutrino8@gmail.com>
+	* Added detection for E-AC3 audio for stream copy and updated the MKV/TS muxing code to support it
+	* Added new option -spr which calculates the Storage and Pixel Aspect Ratios (SAR/PAR) for various
+	  resolutions
+	* Display the amount of chapters each DVD title has when scanning for titles
+	* Display total pixels, SAR and PAR when scanning a file/vcd with the -scan option
+	* Added --no-chapters mkvmerge option for audio files encoded by neroAacEnc so that chapters
+	  won't be copied over to the MKVs from these files
+	* Small update to the install script
+	* Updated the man page. Fix some small cosmetic issues, patch by Alessio Treglia
+	
+* Wed Jul 01 2009 Grozdan Nikolov <neutrino8@gmail.com>
+	* Fallback to undefined audio language in the AUDLANG[$i] variables if we detect unknown language
+	  from MPlayer's output
+	* Added support for bitrate-based ABR Vorbis encoding in addition to quality-based VBR. ABR mode
+	  in Vorbis resembles quality-based VBR except the encoder averages a given nominal bitrate
+	* Updated the Vorbis part of the video bitrate calculation code
+	* Added new function ratio_and_pixels_func() which calculates and displays the Storage Aspect Ratio (SAR),
+	  Pixel Aspect Ratio (PAR) and total pixels from resolution
+	* Bugfix for track 1 in the internal audio encoding code. If using aacplusenc to encode audio, the case
+	  statement had a wrong selection value (aac++ instead of aac+) resulting in displaying a failed message
+	  and forcing an exit even though the encoding may have succeeded
+	* Simplifications to the internal audio encoding code which reduce code duplication
+	* Small fixes to the video bitrate calculation code
+	* Small tuning to the Blu-ray/AVCHD presets
+	* Small cleanups
+	
+* Fri Jun 26 2009 Grozdan Nikolov <neutrino8@gmail.com>
+	* Set default audio codec for the Blu-ray/AVCHD presets to AC3
+	* Bugfix to the OGM muxing code. Second/third track were ignored when one selects AC3 audio
+	* Added keyint, keyint_min, nr and interlaced variables to the custom preset skeleton file 'preset.cfg'
+	* Moved the AACTYPE variable to the neroaac_audio_func() function and updated the specific parts
+	  that use it in the MKV/MP4 muxing code
+	* Do not automatically detect audio sample rate in directory batch encoding mode. Only do it
+	  for single file/dvd/vcd encodings as in batch mode, detection will only print the sample rate of
+	  the first file but not the other files in the directory so this can mislead the user in thinking
+	  that all files in the directory have the sample rate reported by the script. It is possible to
+	  implement sample rate detection for all files but since we don't know how many files are in
+	  the directory, I do not want the user to see a full screen with sample rate info of each file if
+	  he deals with a directory with a few hundreds or more files in it
+	* Disallow autocropping, if enabled in the config file, for directory batch encodings
+	* Small reordering to the MP4 muxing code
+	* Small update to the install script
+	* Updated the man page
+	
+* Wed Jun 24 2009 Grozdan Nikolov <neutrino8@gmail.com>
+	* Removed audio filters for the 1st pass in 2-pass encoding and for the 1st & 2nd pass of
+	  a 3-pass encoding. They are useless here and it's something I've overlooked for a long
+	  time. Thanks to Mat Kanner for noticing and reporting
+	* Some small changes to the way we pass FPS to MP4Box
+	* Added support for MP4 hinting for RTP/RTSP sessions
+	* Simplifications to the external subs importing code. Also fixed a bug in the MP4 subs
+	  importing code; missing -add option in the MP4SUBS variable will make MP4Box fail
+	* Merged the MKV tagging code with the muxing one
+	* Added support for detection of WMA audio for stream copy
+	* Added support for per track audio codecs for DVD encodings. The user can now select
+	  if he wishes for each track a different audio codec. Mixing audio stream copy with
+	  compression codecs is also possible
+	* Updated all relevant audio functions to support per track audio codecs
+	* Updated the bitrate calculation code to support per track audio codecs
+	* Updated the container muxing code to support the above audio changes
+	
+* Mon Jun 22 2009 Grozdan Nikolov <neutrino8@gmail.com>
+	* Small improvement to the MKV/MP4 tagging code: support audio tagging of single file
+	  encodes with audio stream copy
+	* Use array variables ${SUBFILE[2] and ${SUBFILE[3] instead of ${OUTPUT%.*}_sub2
+	  and ${OUTPUT%.*}_sub3 when dumping the second/third DVD subtitles
+	* Simplified the MKV cover art importing code
+	* Small improvements to video bitrate calculation with audio stream copy
+	* Use only one named pipe for all tracks when encoding to neroAAC/AAC+/Vorbis/FLAC
+	* Major audio code restructuring and partial rewrite. Converted virtually all audio
+	  code variables to array variables. This allows for easy extensibility and much less
+	  code duplication. It's very easy now to add as much audio tracks as one may want to the
+	  code with very little changes/updates needed to the containers code. Also the current
+	  changes may allow very easily to support different audio codecs per track in the future
+	* Added support for a third DVD audio track
+	* Updated the video bitrate calculation for target size to support the above audio changes
+	* Converted most of the variables in the video_subtitles_func() function to arrays. This
+	  moderately reduces some code duplication
+	* Updated the container muxing/tagging code to support the above audio changes
+	* Use external flac encoder to encode to FLAC audio as doing it through mencoder is terribly
+	  broken. This updates the config file to version 8 and adds the 'flac' encoder as dependency
+	* Set the default resampling filter to lavcresample as the other one gives problems when
+	  encoding to FLAC audio and resampling
+	  
+* Wed Jun 19 2009 Grozdan Nikolov <neutrino8@gmail.com>
+	* Simplifications to the MKV tagging code which reduces some code duplication
+	* Bugfix: FAAC acodec2 variable has wrong mpeg value. Must be mpeg=4 instead of mpeg4.
+	  This results in failure in encoding of the second audio track when one selects
+	  FAAC as encoder
+	* Bugfix: FLAC audio was ignored for the second track due to missing value in the selection
+	  of the case statement
+	* Added support for tagging of MKV files when doing a directory batch encoding
+	* Replaced the IMPSUB1, IMPSUB2 and IMPSUB3 variables, used to import subs when input type
+	  is file/directory/vcd, by array variables EXTSUB[1], EXTSUB[2] and EXTSUB[3]. This allows
+	  for less code duplication as these array variables are shared by all input types (including DVD)
+	  and thus we only need to do a small loop and add their values if not empty to the
+	  MKVSUBS, MP4SUBS and OGMSUBS variables
+	* Use as temp directory $HOME/.h264enc/job<PID>
+	* Added new function audio_stream_copy_func() which will print a warning that audio stream copy
+	  in directory batch encoding mode is not recommended unless the user is certain that the files
+	  have a supported audio codec by the MKV/MP4/OGM/TS containers
+	* Group audio filters under a submenu similar to how the video filters are grouped
+	* Some small cleanups
+	
+* Wed Jun 17 2009 Grozdan Nikolov <neutrino8@gmail.com>
+	* Added support for per track audio bitrate for DVD encodings
+	* Added support for per track audio normalization and volume adjustments for DVD encodings.
+	  Updated functions audio_volnorm_func() and audio_volume_func()
+	* Added support for per track audio resampling for DVD encodings. Updated functions
+	  audio_resample_filters_func() and audio_resample_func()
+	* Updated the video bitrate calculation code to support the above audio changes
+	* Bugfix for the qt/bd/avchd presets: audio filters were not called for these presets
+	* Added support for per track AAC profile settings (LC/HE/HEv2) when using the
+	  neroAacEnc audio encoder
+	* Small modifications to the MKV/MP4 tagging and muxing code to support the
+	  per track neroAacEnc AAC profiles. This also includes optimizations to the way
+	  the tagging code handles different AAC profiles. If LC profile is chosen, audio will
+	  be tagged as LC-AAC (along with channels info). For HE and HEv2, audio will be tagged
+	  as HE-AACv1 and HE-AACv2 (along with channels info) respectively
+	* Moved the MKV tagging code inside the MKV muxing code
+	* Converted the EXTSUB1, EXTSUB2 and EXTSUB3 variables, used to import external DVD subs,
+	  to arrays so we can easily check different files for their file extensions
+	* Only allow SRT subs as import into OGM. If another subs format is provided, the
+	  subs will be skipped. For MP4, do not allow ASS/SSA subs since it's not supported yet
+	  by MP4Box. For MKV, do not allow SUP and TTXT subs
+	  
+* Mon Jun 15 2009 Grozdan Nikolov <neutrino8@gmail.com>
+	* Update to the video_subtitles_func() function: for DVD encodings, added support
+	  for importing up to three external subtitles into MKV/MP4/OGM. Also added
+	  support for hardcoding an external subtitle into the movie
+	* Updated the MKV/MP4/OGM muxing code to support imports of external subtitles
+	* Increased Psy RD from 0.5 to 0.6 for some presets
+	* If dumping of the second and/or third DVD subtitle fails and user has selected to
+	  import the subs into MKV/MP4, force an exit since container conversion will fail as
+	  the muxing programs will complain about the missing subs. If no container conversion
+	  is chosen or user has chosen not to import the subs and dumping of subs fails, just
+	  continue since there's nothing critical in this case
+	* Use mplayer -really-quiet option instead of redirection to /dev/null when dumping
+	  audio to a named pipe for neroAAC/Vorbis/AAC+ encoding
+	* Some small updates to the man page
+	* Updated the AUTHORS file
+	
+* Fri Jun 12 2009 Grozdan Nikolov <neutrino8@gmail.com>
+	* Replaced the --noaudio mkvmerge option with -A due to recent options changes
+	  in mkvmerge version 2.9.5. -A also works for older versions so nothing breaks here
+	* Removed the check_outfile_func() function as its code has been added to the
+	  set_output_filename_func() function, which also has been improved
+	* Added support for FLAC audio in MKV
+	* Removed some code duplication in the MKV metadata tagging code
+	
+* Tue Jun 09 2009 Grozdan Nikolov <neutrino8@gmail.com>
+	* Added support for adding jpeg/png cover art files to MKV/MP4
+	* Added audio language meta-info for MP4 and TS files
+	* Improved audio language meta-info for MKV files. This also adds metadata
+	  info for the second audio track
+	* Fixed a small bug: the --aac-is-sbr mkvmerge parameter should be set to 0:1
+	  for the second audio track when using aacplusenc as encoder
+	  
+* Mon Jun 08 2009 Grozdan Nikolov <neutrino8@gmail.com>
+	* Add iTunes video title name to MP4 files
+	
+* Sun May 24 2009 Grozdan Nikolov <neutrino8@gmail.com>
+	* Use the same name for the log file as the output file name
+	* Force using the libmpeg2 decoder when encoding DVDs/VCDs (works slightly better in specific
+	  cases compared to ffmpeg2)
+	* Added support for IVTC 59.940 -> 23.976 fps
+	* Some small code cosmetics
+
+* Tue May 12 2009 Grozdan Nikolov <neutrino8@gmail.com>
+	* Added deinterlace combinations of Yadif + linear blend, linear interpolation, cubic
+	  interpolation, median deint, ffmpeg deint and lowpass 5
+	* Cosmetics to the help menu
+	* Added global audio function audio_filters_func() for calling the resample, volume
+	  normalizing and volume filters
+	* Added 16 new variables to the config file for enabling/disabling of specific audio/video
+	  filters and containers: ALLOW_FPS_CONVERSION, ALLOW_SCALER_TUNING, ALLOW_DSIZE,
+	  ALLOW_EXPAND, ALLOW_COLORSPACE, ALLOW_ASPECT, ALLOW_AUD_RESAMPLE, ALLOW_AUD_NORMALIZE,
+	  ALLOW_AUD_VOLUME, ALLOW_MKV_MUXING, ALLOW_MP4_MUXING, ALLOW_TS_MUXING, ALLOW_OGM_MUXING,
+	  ALLOW_SAMPLE_ENCODING, ALLOW_SCAN_MULTIPLE_VIDSTREAMS and ALLOW_SCAN_MULTIPLE_AUDSTREAMS,
+	  the last two are only effective on file and directory batch encodings
+	* Updated the man page
+
+* Thu May 7 2009 Grozdan Nikolov <neutrino8@gmail.com>
+	* Automatically add the shebang line to batch files and make them executable
+	* Added new variable ALLOW_AUTOCROP to the config file which allows the user to enable or
+	  disable automatic cropping
+	* Added MP3 presets and updated target file size code to support them (requested by Rogério Brito)
+	* Some minor adjustments to the hq, vhq, ehq, uhq and ihq presets; decrease b-frames by one
+
+* Wed Apr 29 2009 Grozdan Nikolov <neutrino8@gmail.com>
+  - Small bugfix: video filters variables in the config file were not respected when one
+    chooses to encode VCDs. 
+  - Add video title meta-data for MKV and OGM when doing directory batch encodings
+
+* Tue Apr 28 2009 Grozdan Nikolov <neutrino8@gmail.com>
+	* Optimize some variables by replacing piping to sed with VARIABLE1="${VARIABLE2%.*}.ext"
+	* Move out the built-in -loop 1 mplayer option to the config file's MPLAYEROPTS variable
+	* Add support for enabling/disabling specific pre/postprocessing filters in the config file.
+	  This adds 7 new variables to the config file where the user can either enable to ask
+	  questions about a specific filter or disable a specific variable, thus skipping
+	  questions about the filter
+	* Moved the video filters code to a new function called video_filters_func(). This also
+	  reduces a bit of code duplication
+	* Add a new option -e which allows the user to edit the config file directly from within the
+	  terminal. This adds a new variable EDITOR to the config file where the user can set his
+	  preferred text editor (defaults to nano)
+	* Silence possible dvdxchap warnings
+	* Updated the man page
+
+* Thu Apr 26 2009 Grozdan Nikolov <neutrino8@gmail.com>
+	* Bugfix: missing 's' in the sed expression of the MP4OUT variable. This results in
+	  missing output file and will fail when one tries to remux to mp4
