MKVToolNix v7.4.0 released


I’ve released mkvtoolnix v7.4.0. It’s mostly a bug-fix release, though kind of important if you mux HEVC or teletext subtitles.

For packagers: nothing has changed since the previous release.

You can download the source code or one of the binaries.

Here’s the full ChangeLog since the previous release:

  • 2014-12-12 Moritz Bunkus <>
    • Released v7.4.0.
  • 2014-12-10 Moritz Bunkus <>
    • mkvmerge: bug fix: mkvmerge was sometimes dropping lines from teletext subtitles read from MPEG transport streams. See #773.
  • 2014-12-05 Moritz Bunkus <>
    • mkvmerge: bug fix: The PCM packetizer was producing wrong track statistics by disregarding the last packet’s duration when reading PCM data from packaged sources (Matroska, MP4 files). Fixes #1075.
    • build system: enhancement: configure will look for a system version of the pugixml library and use that instead of the bundled version if it is found. Fixes #1090.
    • mkvextract: bug fix for chapter & tag extraction: If locale is set to a non-UTF locale (including C or POSIX) then no XML data was output at all even if the XML data contained ASCII characters only. Fixes #1086. This also fixes mkvextract writing two BOMs when extracting tags with the »–redirect-output« option on Windows.
  • 2014-11-19 Moritz Bunkus <>
    • mkvinfo: bug fix: summary mode: reported frame types in block groups are now derived from the number of references found and not by the references’ values.
  • 2014-11-16 Moritz Bunkus <>
    • mkvmerge: bug fix: Fixed muxing open GOPs after I frames in MPEG-1/2 video (patch by Stefan Pöschel). Fixes #1084.
  • 2014-11-15 Moritz Bunkus <>
    • mmg: bug fix: VP9 video tracks are accepted in WebM mode.
  • 2014-11-05 Moritz Bunkus <>
    • mkvmerge: bug fix: Cherry-picked several commits from DivX’ mkvmerge fork for improved HEVC handling. Fixes #1076.
    • all: new feature: added a Catalan translation of the programs by Antoni Bella Pérez (see AUTHORS).
  • 2014-11-04 Moritz Bunkus <>
    • mkvmerge: bug fix: Fixed the handling of Big Endian PCM tracks read from MP4 files. Fixes #1078.

Have fun.
