mkvtoolnix/ChangeLog

2004-01-11  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: new feature: Added the two new chapter flags 'hidden'
	and 'enabled'.

	* mkvmerge: new feature: Added a new format for the external
	timecode files.

2004-01-09  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: bug fix: The VobSub handling was on occasion putting
	SPU packets for the wrong MPEG stream into the current stream
	resulting in that particular entity not being displayed.

2004-01-06  Moritz Bunkus  <moritz@bunkus.org>

	* Released v0.8.1.

2004-01-05  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: bug fix: The I/O classes were not initialized
	correctly on Windows resulting in spontaneous strange error
	messages, especially when muxing VobSubs.

2004-01-03  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: bug fix: For some special atom sizes in Quicktime and
	MP4 files the size was not read correctly. This affected
	e.g. files created by Nero Digital.

2004-01-02  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: bug fix: Segfault when muxing some video formats due
	to unchecked data (includes RealVideo).

2004-01-01  Moritz Bunkus  <moritz@bunkus.org>

	* Released v0.8.0.

2003-12-29  Moritz Bunkus  <moritz@bunkus.org>

	* mmg: bug fix: Fixed the "write chapters to Matroska file"
	feature.

	* mmg: bug fix: Made mmg not abort but only display an error
	message when malformed XML chapter files should be loaded.

2003-12-28  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: bug fix: The timescodes for Vorbis were calculated one
	packet too early (meaning that the first packet did not start at
	0).

	* mmg: Made "don't link" ON by default because some players might
	have problems with the second and all following files if they
	don't expect them not to start at 0.

	* mkvmerge, mkvextract, mkvinfo: Added support for the new tagging
	system.

	* mmg: bug fix: The default values for the chapter language and
	chapter country are now applied when loading simple (OGM) style
	chapter files as well.

	* mkvmerge: bug fix: The VobSub packetizer will assume MPEG2 if no
	MPEG version identifier was found ("Unsupported MPEG version:
	0x00...").

2003-12-23  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: There are MP4 files that actually contain HE-AAC but
	don't have the 5 byte identifier. mkvmerge will also assume SBR if
	there's only the 2 byte identifier with a sampling frequency <
	44100Hz.

2003-12-22  Moritz Bunkus  <moritz@bunkus.org>

	* mkvextract: bug fix: Wrong display output and illegal memory
	access when extracting FLAC files.

2003-12-17  Moritz Bunkus  <moritz@bunkus.org>

	* mmg: bug fix: If one added a Matroska file and the track name or
	language of a track consisted of only blanks then mmg would
	segfault. 

2003-12-15  Moritz Bunkus  <moritz@bunkus.org>

	* mmg: The input box will automatically select the first track
	when a file is selected. Upon track selection the input focus is
	set to the track name input box.

	* mmg: The chapter editor automatically focuses the chapter name
	input box whenever a chapter entry is selected.

	* mmg: bug fix: The chapter editor did not properly escape the
	chapter names resulting in invalid XML files if the special
	characters &, < or > were used.

2003-12-12  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: bug fix: If splitting was active then a wrong CodecID
	was written to the second and all following files for MP2 tracks.

2003-12-11  Moritz Bunkus  <moritz@bunkus.org>

	* Released v0.7.9.

2003-12-05  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: Set the thread priority to BELOW_NORMAL on Windows
	(mkvmerge was already nice(2)'d on Unix systems).

	* mmg: bug fix: Removed the Ctrl-v and Ctrl-c accelerators that I
	used for mmg functions which overrode the usual 'paste' and 'copy'
	functionality.

	* mmg: Command line arguments are put into an option file which is
	then handed over to mkvmerge. This allows really long command
	lines, even on Windows.

	* mkvmerge: bug fix: Negative track IDs in Ogg files were reported
	incorrectly for mkvmerge -i (which affected the GUI).

	* mkvmerge: bug fix: Internal changes had messed up the --language
	and --track-name functionality.

2003-12-04  Moritz Bunkus  <moritz@bunkus.org>

	* mmg: new feature: Added "up" and "down" buttons for the tracks,
	too.

	* mmg: new feature: Added a menu option, 'set output file', that
	can be used as an alternative to the "browse" button at the bottom
	(for those poor users with nothing more than 800x600 ;)).

	* mkvmerge: new feature: The user can alter the order in which the
	tracks for an input file are put into the output file with the new
	"--track-order" option.

	* mmg: bug fix: The "AAC is SBR" check box was grayed out for AAC
	inside MP4 files.

2003-12-03  Moritz Bunkus  <moritz@bunkus.org>

	* mmg: bug fix: The "load settings" function did not load all
	settings, and some strings were not allocated at all resulting in
	a crash when a track was removed after loading these settings.

	* mkvmerge: bug fix: The AAC packetizer was not working if packets
	were being read from a raw AAC file (it worked fine from MP4 and
	Matroska files).

	* mkvmerge: bug fix: Avoid deadlocks when parsing broken SPU
	packets from VobSubs.

	* mmg: new feature: Added buttons for moving input files up and
	down in the input file box.

2003-12-02  Moritz Bunkus  <moritz@bunkus.org>

	* Released v0.7.8.

	* mmg: new feature: You can set the values for the language and/or
	country codes for a chapter and all its children with the push of
	one button (the new "Set values" button).

	* mmg: new feature: You can set default values for the language
	and the country codes in the chapter editor (Chapter menu -> Set
	default values).

2003-12-01  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: bug fix: Display dimensions were sometimes off by one,
	e.g. 640x479 instead of 640x480. This should not happen anymore
	for sane pixel dimensions.

	* mkvmerge: Changed the options '--fourcc' and
	'--aspect-ratio'. They now take a track ID just like all the other
	track specific options.

	* mkvmerge: new feature: Added an option '--display-dimensions'
	which allows the direct setting of the display dimensions. It is
	mutually exclusive with '--aspect-ratio', of course.

2003-11-29  Moritz Bunkus  <moritz@bunkus.org>

	* mmg: bug fix: The language combo box was not correctly set on
	Windows.

2003-11-25  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: Added an option for dumpig all split points including
	file size and timestamp information after the first splitting
	pass.

2003-11-23  Moritz Bunkus  <moritz@bunkus.org>

	* mmg: bug fix: Quotes were missing if the timecode file's name
	contained spaces.

2003-11-18  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: Rewrote the SPU packet parsing code. It should not
	abort anymore.

	* everything: Committed a lot of cross-OS compatibility fixes
	(thanks to Haali and thedj).

2003-11-16  Moritz Bunkus  <moritz@bunkus.org>

	* Released v0.7.7.

	* mkvextract: Added extraction of FLAC to raw FLAC or OggFLAC
	files.

	* mkvmerge: Added full support for FLAC (both raw FLAC and OggFLAC
	are supported, even though raw FLAC is very slow).

2003-11-15  Moritz Bunkus  <moritz@bunkus.org>

	* mmg: Added an input field for the 'CUE sheet to chapter name'
	conversion format.

	* mkvmerge: bug fix: Reworked the audio sychronization which did
	not work correctly for Matroska source files.

2003-11-13  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: bug fix: Increased the size of the space reserved for
	the first meta seek element (see mkvmerge.1 for an
	explanation). In some situations (with tags, chapters,
	attachements and very big file) it might not have been enough in
	order to contain all elements.

2003-11-12  Moritz Bunkus  <moritz@bunkus.org>

	* mmg: Added an input field for the 'timecodes' file to the track
	options.

	* mkvmerge: bug fix: When reading MP3 audio tracks from a Matroska
	file with the A_MS/ACM CodecID (MS compatibility mode) the layer
	was not identified correctly.

	* mkvmerge: Improved the file type detection for AC3 and AAC files
	a bit.

	* mkvmerge: Implemented a lot of fixes for big endian systems and
	processors that don't allow non-aligned memory access for word or
	bigger sized objects.

	* mmg: Made mmg accept return codes of 1 when 'mkvmerge -i' is run
	when an input file is added. This way mmg won't reject mkvmerge's
	output if mkvmerge only printed some warnings which will result in
	a return code of 1 instead of 0.

	* mkvmerge: bug fix: If running in identification mode (-i, used
	by mmg a lot) then don't output any warnings or mmg will not
	accept this file.

2003-11-10  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: new feature: CUE sheets can be used for chapters.

2003-11-09  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: Added support for --sync for VobSub tracks.

	* mkvtoolnix: Re-worked the configure script. Removed all the lib
	specific --with-...-include and --with-...-lib options. The
	--with-extra-includes and --with-extra-libs options can be used
	instead.

2003-11-08  Moritz Bunkus  <moritz@bunkus.org>

	* mmg: When a file is being added then some information from it
	(languages, track names, file title) are kept, and the appropriate
	input boxes are pre-set with these values. Works only for formats
	that support such information (Matroska, VobSub).

	* mkvmerge: Sped up the reading of VobSub .idx files.

2003-11-05  Moritz Bunkus  <moritz@bunkus.org>

	* Released v0.7.5.

	* mkvmerge: bug fix: The VobSub .idx parser was dividing by 0 if
	a track only contained one entry.

	* mkvmerge: Fixed the timecode reader code and made it a bit more
	flexible. Added more documentation for this feature along with an
	example file (examples/example-timecodes.txt).

	* mmg: bug fix: When 'default track' is selected then all other
	tracks of the same type will have their 'default track' flag
	cleared.

	* mkvmerge: SPU packets belonging to the same timecode are grouped
	together, and the duration is extracted directly from the SPU
	stream.

2003-10-29  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: The VobSubs are now stripped of the MPEG program
	stream, and only the SPU packets are kept.

2003-10-28  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge, mkvextract: The Matroska reader and the OGM reader
	(mkvmerge) as well as mkvextract will discard empty or 'cleaning
	only' subtitle packets as they are appear in OGMs in order to mark
	the end of an entry.

2003-10-27  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: new feature: Added the ability to read timecodes from
	text files which override the timecodes mkvmerge calculates
	normally.

2003-10-26  Moritz Bunkus  <moritz@bunkus.org>

	* mkvextract: bug fix: Add all the mandatory elements when
	extracting chapters so that the resulting XML can always be used
	directly with mkvmerge again without having to manually add
	e.g. ChapterLanguage.

	* mkvmerge: bug fix; Handle audio tracks from Matroska files with
	the CodecID A_MS/ACM correctly.

2003-10-25  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: Changes to use libmatroska's new lacing code.

2003-10-23  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: bug fix: The VobSub .idx parser was mis-calculating
	the subtitle entry frame sizes.

	* mkvmerge: bug fix: The Vorbis packetizer was miscalculating the
	number of samples to add/remove when using audio sync.

2003-10-22  Moritz Bunkus  <moritz@bunkus.org>

	* mmg: new feature: Added a new menu entry "File -> new" which
	will clear all the current muxing settings.

	* mmg: Added support for VobSub subtitles including their
	compression options. Added the .m4a extension to the 'add file'
	dialog.

	* mmg: bug fix: Made the input boxes for file names (tags and
	chapters) editable so that their contents can be deleted.

	* mkvmerge: Adjusted the compression handling to the final content
	encoding specs.

2003-10-19  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: new feature: Implemented generic support for frame
	compression (mostly useful for VobSub subtitles but could also be
	used for others) and the complete framework for handling content
	encodings in the Matroska reader.

2003-10-18  Moritz Bunkus  <moritz@bunkus.org>

	* mkvinfo: new feature: Dump unknown elements recursively.

2003-10-15  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: bug fix: Made the SRT reader more tolerant regarding
	empty lines.

2003-10-14  Moritz Bunkus  <moritz@bunkus.org>

	* Released v0.7.2.

	* mkvmerge: bug fix: If 'no linking' and splitting was active
	mkvmerge would abort on the start of the second output file due to
	timecodes that were calculated incorrectly.

	* mkvmerge: Implemented some speedups for a couple of container
	formats and track types (mainly AVI reader, MP3/AC3/AAC
	packetizers). Especially noticeable when splitting is active as
	well.

2003-10-12  Moritz Bunkus  <moritz@bunkus.org>

	* mkvextract: bug fix: Support for extracting SBR AAC (previous
	'fix' did not actually fix this).

	* mkvextract: bug fix: All extracted subtitles where written to
	the first output file given, not to the one they were supposed to
	be written to.

2003-10-11  Moritz Bunkus  <moritz@bunkus.org>

	* mmg: bug fix: The 'abort' button was doing nothing under
	Windows.

2003-10-06  Moritz Bunkus  <moritz@bunkus.org>

	* mmg: bug fix: Audio, video and subtitle track selection was
	translated into the wrong command line options.

	* mkvmerge: Replaced the avilib based AVI reading functions with
	AVI classes from Cyrius.

2003-10-03  Moritz Bunkus  <moritz@bunkus.org>

	* Released v0.7.1.

	* Added a guide for mmg including some pictures.

2003-10-01  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: Changed the lacing strategy again. New defaults are
	NOT to write duration elements for all blocks, NOT to use time
	slices and to USE lacing for most audio tracks. This will save
	some space. The downside is that the laced frames 'lose' their
	precise timecode information. Current demuxers don't care and will
	work nevertheless. More sophisticated applications that make use
	of these advanced information (duration elements, time slices) are
	not available at the moment. All these options can be toggled by
	the user with the new/modified options --disable-lacing,
	--enable-durations and --enable-timeslices.

2003-09-29  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: new feature: Attachments are kept when reading
	Matroska files.

2003-09-28  Moritz Bunkus  <moritz@bunkus.org>

	* mmg: new feature: Added a (nearly) full-featured chapter editor.

2003-09-26  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: bug fix: XML chapters were not parsed correctly.

2003-09-24  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: bug fix/new feature: Rewrote the complete MP3
	handling. Now files with ID3 tags (both v1 and v2) are handled
	correctly. All MPEG-1 audio files (all layers) should be handled
	correctly now.

2003-09-23  Moritz Bunkus  <moritz@bunkus.org>

	* mkvextract: new feature: Support for extract HE-AAC tracks to
	.aac files. Bug fix: Missing elements (default values) are handled
	correctly for audio tracks.

2003-09-19  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: bugfix: If attachments were given with path components
	then the path component wasn't discarded for the attachment's
	description on Windows (normally only the file name should be used
	as the attachment's name).

	* mmg: Fixed wrong order of the options --chapters,
	--chapter-language and --chapter-charset.

2003-09-17  Moritz Bunkus  <moritz@bunkus.org>

	* mmg: Added a lot of checks on the data given by the user so that
	invalid data is reported by mmg and not by mkvmerge.

	* mmg: Made the app a GUI app which gets rid of the "DOS box" on
	Windows.

2003-09-16  Moritz Bunkus  <moritz@bunkus.org>

	* mmg: bugfix: Moved the aspect ratio and FourCC input fields from
	the global tab to the input tab where they belong to.

	* mkvmerge: new feature: RealAudio can be read from Matroska
	files.

	* mkvmerge: bugfix: RealVideo was not read correctly from Matroska
	files.

	* mkvmerge: bugfix: The SRT reader would abort if there was more
	than one empty line between subtitle entries line.

	* mkvextract: bugfix: Proper BOMs are written according to the
	desired charset when extracting text subtitles.

	* Released v0.7.0.

	* mkvextract: Add an UTF-8 BOM to extracted SSA/ASS and SRT
	subtitle files. Print warnings for missing durations for text
	subtitle tracks.

2003-09-14  Moritz Bunkus  <moritz@bunkus.org>

	* Added a complete GUI for mkvmerge, mkvmergeGUI (mmg) based on
	the work of Florian Wagner.

2003-09-12  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: Support for setting the track names.

	* mkvmerge: For Matroska source files: If the source contains
	chapters then these are kept unless the user specified chapters
	with --chapters.

2003-09-11  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: Implemented an experimental VobSub reader and
	packetizer. No specs exist for these yet, though.

	* mkvmerge: Improved the support for Matroska files with tracks
	with big gaps between entries, e.g. subtitle tracks whose entries
	are a minute or more apart.

	* mkvmerge: When splitting is active and the source is a Matroska
	file then splitpoints were borked, and the first pass was slow as
	your average mole.

	* mkvmerge: The track UIDs are kept when reading Matroska files
	even when splitting is active.

2003-09-09  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: Added a QuickTime/MP4 reader. Can handle several
	QuickTime video and QuickTime audio formats as well as AAC (both
	'normal' AAC and SBR AAC).

2003-09-08  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: DisplayWidth and DisplayHeight are kept intact when
	reading from a Matroska file but can be overridden with
	--aspect-ratio.

2003-08-30  Moritz Bunkus  <moritz@bunkus.org>

	* Wrote documentation, XML examples and the DTD for the XML
	chapter files.

	* mkvinfo: Rewrote mkvinfo to use libebml's Read() function
	instead of manually reading each and every element.

	* mkvmerge: Added support for XML based chapter files.

2003-08-29  Moritz Bunkus  <moritz@bunkus.org>

	* Released v0.6.5.

2003-08-28  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: On Windows the 'isspace()' function used to trim
	leading and trailing white spaces from tags considered some parts
	of valid UTF-8 character sequences to be white spaces as
	well. Fixed by replacing 'isspace()' with 'isblank()'. Reported
	by Liisachan.

	* mkvmerge: Support for chosing the charset and language used in
	simple chapter files. Suggestion by Liisachan.

	* Rewrote the UTF-8 conversion routines. They should now handle
	U+8000 characters correctly. Reported by Liisachan.

	* mkvmerge: Real reader: For RV40 the actual dimensions were also
	used for the aspect ratio/display dimensions. This has been fixed:
	the actual dimensions are used for PixelWidth/PixelHeight, the
	dimensions stored in the RM container are used for the aspect
	ratio/DisplayWidth & DisplayHeight. Reported by Karl Lillevold.

2003-08-27  Moritz Bunkus  <moritz@bunkus.org>

	* Released v0.6.4.

	* mkvextract: Support for re-creating dropped frames when
	extracting video to an AVI. Works only well if the frame durations
	in the source file are multiples of the frame rate, of course.

	* mkvmerge: The MP3 packetizer did not start at 0 with its
	timecodes. It does now. Reported by alexnoe.

	* mkvmerge: Proper support for dropped frames when reading AVI
	files. Reported by alley_cat, Horv<72>th Istv<74>n.

	* mkvmerge: Fixed some missing default values in the Matroska
	reader (e.g. mono audio files). Reported by Liisachan.

2003-08-25  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: Improved all command line parsing error messages.

	* mkvmerge: Improved the error message for the XML tag file parser
	if an invalid &-sequence is found.

	* mkvextract: Strings are postprocessed so that the special
	characters &, <, >, " are replaced by their HTML equivalents
	&amp;, &lt, &gt; and &quot;.

2003-08-24  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: Disabled lacing by default and renamed --no-lacing to
	--enable-lacing. With all the proper info about the laced frames
	lacing is actually producing larger files than without lacing.

	* mkvmerge: Meta seek element is split into two elements. The
	first's located at the start of the file containing only a small
	number of level 1 elements. The clusters are referenced in a
	second meta seek element located at the end of the file. Removed
	the options "--meta-seek-size" and "--no-meta-seek". Added the
	option to disable that second meta seek entry,
	"--no-clusters-in-meta-seek".

2003-08-22  Moritz Bunkus  <moritz@bunkus.org>

	* mkvextract: Backwards compatibility: Accepts S_SSA and S_ASS as
	valid CodecIDs (new CodecIDs are S_TEXT/SSA and S_TEXT/ASS).

	* mkvmerge: Bugfix: If a subtitle packet was the last packet in a
	cluster then its duration was not written resulting in a broken file.

2003-08-21  Moritz Bunkus  <moritz@bunkus.org>

	* mkvinfo: Added support for the following elements:
	KaxPrevFilename, KaxNextFilename, KaxTrackFlagEnabled,
	KaxTrackName, KaxCodecName, KaxCodecSettings, KaxCodecInfoURL,
	KaxCodecDownloadURL, KaxCodecDecodeAll, KaxTrackOverlay,
	KaxAudioPosition, KaxAudioOutputSamplingFreq, KaxVideoDisplayUnit,
	KaxVideoColourSpace, KaxVideoGamma, KaxVideoFlagInterlaced,
	KaxVideoStereoMode, KaxVideoAspectRatio, KaxClusterPosition,
	KaxClusterPrevSize, KaxBlockVirtual, KaxBlockAdditions,
	KaxBlockMore, KaxBlockAddID, KaxBlockAdditional,
	KaxReferenceVirtual, KaxSliceBlockAddID, KaxChapters,
	KaxEditionEntry, KaxChapterAtom, KaxChapterUID,
	KaxChapterTimeStart, KaxChapterTimeEnd, KaxChapterTrack,
	KaxChapterTrackNumber, KaxChapterDisplay, KaxChapterString,
	KaxChapterLanguage, KaxChapterCountry

2003-08-20  Moritz Bunkus  <moritz@bunkus.org>

	* Released v0.6.3.

	* mkvmerge: The Real reader accepts incomplete video packets and
	tries to re-assemble them instead of aborting with 'die: len !=
	total'.

2003-08-18  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: Implemented a switch that has to be used for SBR AAC /
	AAC+ / HE-AAC if the source file is an AAC file and the AAC file
	contains SBR AAC data (no automatic detection possible in this case!).

2003-08-14  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: Low bitrate AC3 tracks from Real's DNET are identified
	as A_AC3/BSID9 or A_AC3/BSID10.

	* mkvmerge: The RealMedia reader takes the number of packets into
	account when reading which results in better end-of-file detection.

2003-08-12  Moritz Bunkus  <moritz@bunkus.org>

	* Windows versions: Fixed a bug with files bigger than 2GB not
	being recognized. The accompanying error message was "File NAME
	has unknown type. Please have a look at the supported file
	types..."

	* all tools: Fixed a bug which would only allow Matroska files up
	to 4GB to be read. The accompanying error message was "No segment
	found" or something similar.

	* mkvinfo: Unknown elements are properly skipped now.

2003-08-11  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: For RV40 (RealVideo 9) the actual video dimensions are
	decoded from the first video frame.

	* Released v0.6.2.

	* mkvmerge: Video aspect ratio was set wrong if the user did not
	specify any.

	* Released v0.6.1.

	* mkvmerge: RealVideo: Support for all kinds of frames including
	"short" and "merged" frames (results are identical to Gabest's
	output).

2003-08-10  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: The aspect ratio setting will only cause upscaling of
	the current video dimensions which are then put into
	KaxVideoDisplayWidth and KaxVideoDisplayHeight.

	* mkvextract: Changed how the global elements are handled by
	taking the parent's size into account. This re-enables processing
	of files produced with the latest VirtualDubMod.

	* mkvmerge: Changed how the Matroska reader handles global
	elements by taking the parent's size into account. This re-enables
	processing of files produced with the latest VirtualDubMod.

	* mkvinfo: Changed how mkvinfo handles global elements by taking
	the parent's size into account. Hopefully this is now correct.

	* mkvextract: Support for MultiComment tags.

	* mkvmerge: Fixed support for reading MultiComment tags from
	XML tag files.

	* mkvmerge: Allow some slightly broken Matroska files to be
	processed correctly if the reference blocks are off by at most 1ms.

2003-08-09  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: MP3: Better support for other MPEG versions and layers
	(number of samples per packet).

	* mkvinfo: Added Adler32 calculation and display for frame
	contents with the -c option.

	* mkvmerge: RealAudio: "dnet" is actually byte-swapped AC3 and is
	being treated as such (re-swapped and output as AC3).

	* mkvmerge: Fixed a bug with chapters and splitting which would
	crash mkvmerge if no chapter belonged into the output file.

2003-08-06  Moritz Bunkus  <moritz@bunkus.org>

	* Changes for compilation with gcc 2.95.

2003-08-04  Moritz Bunkus  <moritz@bunkus.org>

	* Released v0.6.0.

2003-07-30  Moritz Bunkus  <moritz@bunkus.org>

2003-07-26  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: Added support tags based on XML files.

	* mkvextract: Rewrote the command line syntax. Added extracting

	* mkvmerge: Added support for UTF-8 and UTF-16 encoded text files
	for the SRT and SSA/ASS readers.

2003-07-15  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: The SSA/ASS reader ignored the --sub-charset option
	and always used the current charset to recode the subtitles.

2003-07-14  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: Added support for attaching files to the output
	file(s).

	* mkvinfo: Support for the elements dealing with attachments
	(KaxAttachments, KaxAttached, KaxFileDescription, KaxFileName,
	KaxMimeType, KaxFileData).

2003-07-13  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: Changed the RealVideo packaging method: Subpackets are
	assembled into complete packets so the demuxer does not have to do
	that anymore.

	* mkvmerge: DisplayWidth and DisplayHeight, which form the display
	aspect ratio, are now always written to ease changing them later
	without having to completely remux the file.

2003-07-08  Moritz Bunkus  <moritz@bunkus.org>

	* mkvmerge: Fixed some infinite-reading-from-a-file bug that
	occured on Windows when reading SSA/ASS files.

	* mkvmerge: Fixed a bug which would mostly appear with subtitles
	that have very long ( > 60s) gaps between entries. Here the
	cluster would not been rendered properly leaving mkvmerge either
	comatose ( = endless loop) or just plain dead ( = crashing).

2003-07-07  Moritz Bunkus  <moritz@bunkus.org>

	* mkvinfo: Added support for the rest of the tags:
	KaxTagMultiComment, KaxTagMultiCommentName,

	* Removed "(mkvinfo) " from mkvinfo's output in order to improve
	readability and save space.

	* --sub-charset now also needs a track ID.

	* If an error occurs while writing to the destination file the
	error is reported and mkvmerge aborts with a non-zero exit code.
