Hey,

I've released mkvtoolnix v5.4.0. It's a release that contains one huge
improvement: the AVC/h.264 timecode assignment code has been
completely rewritten. Users do not have to specify the default
duration/FPS for such tracks anymore safe for the rarest cases. Apart
from that there were tons of bug fixes, improvements regarding file
type recognition, and a complete re-write of the (E)AC3 parsing code.

A note for package maintainers: Boost's rational library is now required.

All of the Linux binaries that I provide have already been built and
are available.

Here's the full ChangeLog since release 5.3.0:

------------------------------------------------------------
2012-03-10  Moritz Bunkus  <moritz at bunkus.org>

	* Released v5.4.0.

2012-03-08  Moritz Bunkus  <moritz at bunkus.org>

	* mkvmerge: bug fix: Fixed wrong calculation of the maximum number
	of ns per cluster in certain fringe cases if timecode scale was
	set to "auto" mode ("--timecode-scale -1"). Fix for bug 707.

2012-03-07  Moritz Bunkus  <moritz at bunkus.org>

	* build system: The C++ compiler must now support the C++11
	keyword 'nullptr'. configure checks for it. For GCC this means at
	least v4.6.0.

	* mkvinfo: new feature: mkvinfo will output the track ID that
	mkvmerge and mkvextract would use for a track. This information is
	shown alongside the "track number" element in verbose mode and in
	the track summary in summary mode.

	* mkvmerge, mmg: enhancement: The "--default-duration" in mkvmerge
	and the "FPS" drop down box in mmg now accept "p" or "i" as a unit
	-- as in e.g. "25p" or "50i". Several commonly used values have
	been added to mmg's "FPS" drop down box and others removed.

	* mkvmerge: bug fix: When using an external timecode file with
	AVC/h.264 video the default duration will be set to the most-often
	used duration in the timecode file.

	* mmg: enhancement: Added the values "50", "60" and "48000/1001"
	to the list of commonly used values for the "FPS" input field.

	* mkvmerge: bug fix: AVC/h.264 packetizer: The value given with
	"--default-duration" (after internal conversion from the unit
	given by the user to duration in nanoseconds) is now again
	interpreted as the duration of a frame and not of a field.

	* mkvmerge: bug fix: SRT subtitles: timecodes can contain the
	minus sign before any digit, not just before the first one.

2012-03-05  Moritz Bunkus  <moritz at bunkus.org>

	* mkvmerge: bug fix: Sometimes non-AC3 files were mistakenly for
	AC3 after the re-write of the AC3 handling code on
	2012-02-26. This has been rectified. Fix for bug 723.

2012-03-04  Moritz Bunkus  <moritz at bunkus.org>

	* mkvmerge: enhancement: mkvmerge will keep the "enabled" track
	header flag when muxing. mkvmerge will also output its value in
	verbose identification mode as "enabled_track".

	* mkvmerge: enhancement: MicroDVD text subtitles are recognized as
	an unsupported format instead of an unknown format.

	* mmg: The warning that no default duration/FPS has been given for
	AVC/h.264 tracks has been removed.

	* mkvmerge: bug fix: Complete re-write of the timecode handling
	code for AVC/h.264 tracks. Now handles several cases correctly:
	interlaced video, video with multiple or changing SPS with
	different timing information. The timing information is extracted
	from the bitstream. Therefore the user doesn't have to specify the
	default duration/FPS himself anymore. Fix for bugs 434 and 688.

2012-02-26  Moritz Bunkus  <moritz at bunkus.org>

	* build system: Boost's "rational" library is now required.

	* mkvmerge: bug fix: Complete re-write of the (E)AC3 parsing and
	handling code. Dependent EAC3 frames are now handled
	correctly. Fix for bug 704.

2012-02-22  Moritz Bunkus  <moritz at bunkus.org>

	* mkvmerge: bug fix: The width and height of h.264 video tracks
	with a pixel format other than 4:2:0 are now calculated
	correctly. Fix for bug 649. Patch by Nicholai Main (see AUTHORS).

	* mkvmerge: bug fix: Fixed file type recognition and frame drops
	for VC1 elementary streams that do not start with a sequence
	header but with frame or field packets instead.

	* mkvmerge: bug fix: Fixed mis-detection as unsupported DV files
	(happened for e.g. PGS subtitle files).

2012-02-12  Moritz Bunkus  <moritz at bunkus.org>

	* doc: enhancement: Updates for option file usage and supported
	subtitle formats.

Have fun.
