MKVToolNix v5.4.0 released

2012-03-10 — mosu

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.

Here are the usual links: the home page, the source code and the Windows installer and 7zip archive.

All of the binaries that I provide myself are already available.

Here’s the full ChangeLog since release 5.3.0:

• 2012-03-10 Moritz Bunkus <moritz@bunkus.org>
  • Released v5.4.0.
• 2012-03-08 Moritz Bunkus <moritz@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@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@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@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@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@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@bunkus.org>
  • doc: enhancement: Updates for option file usage and supported subtitle formats.

Have fun.
