MKVToolNix v9.6.0 released

This release fixes one major bug in mkvmerge (an endless loop) when appending files. It mostly occurred when muxing MPLS playlists. Several other minor bug fixes and usability enhancements were implemented.

Nothing’s been changed regarding the packaging since v9.5.0.

You can download the source code or one of the binaries. All of the binaries that I provide myself have been built already and are available for download.

Here’s the full ChangeLog since the previous release:

    • mkvmerge & mkvextract: added support for HDMV TextST subtitles.
  • 2016-11-20 Moritz Bunkus <>
    • mkvextract: VobSub bug fix: mkvextract will add a "langidx" line to the .idx file upon extraction. Fixes #1810.
  • 2016-11-14 Moritz Bunkus <>
    • MKVToolNix GUI: multiplexer enhancement: added a column "source file’s directory" to the track list. Implements #1809.
    • MKVToolNix GUI: multiplexer enhancement: added an option for selecting all tracks of the currently selected source files in the source file context menu. Inspired by #1809.
  • 2016-11-07 Moritz Bunkus <>
    • MKVToolNix GUI: job output tool bug fix: the button for acknowledging warnings & errors wasn’t properly disabled when the user used outside methods of acknowledging them (e.g. via the menu or via the job queue). Fixes #1802.
  • 2016-10-31 Moritz Bunkus <>
    • mkvmerge: MPLS parser bug fix: fixed reading the "in" & "out" timestamps for "play items". This bug resulted in mkvmerge not reading the correct range from the referenced M2TS file under certain rare circumstances.
  • 2016-10-30 Moritz Bunkus <>
    • mkvmerge: bug fix: mkvmerge was entering endless loops under certain conditions when appending files. This was a regression introduced with the fix to #1774 (using very large –sync values causing mkvmerge to abort).
  • 2016-10-23 Moritz Bunkus <>
    • MKVToolNix GUI: new feature: added options in the preferences to only show the list of often used languages/country codes/character sets in their respective selections instead of both the often used and the full list. Implements #1796.
