MKVToolnix

MKVToolnix is a set of tools to create, alter and inspect Matroska files under Linux, other Unices and Windows. They do for Matroska what the OGMtools do for the OGM format and then some.

With these tools one can get information about (mkvinfo) Matroska files, extract tracks/data from (mkvextract) Matroska files and create (mkvmerge) Matroska files from other media files. Matroska is a new multimedia file format aiming to become THE new container format for the future.

  ## New features and enhancements
  
  
  * mkvmerge: HDMV PGS subtitles: mkvmerge now tries to detect bogus timestamps
    (where the current timestamp is two hours or more after the previous
    timestamp) & correct them to something more sensible (1s after the previous
    timestamp). That way one bogus timestamp cannot cause the rest of the frames
    to not be interleaved properly with the other audio & video
    packets. Implemented for #3268.
  * mkvmerge: added colour information, colour mastering meta information &
    video projection information properties to the JSON identification
    format. The properties are reported for container types for which mkvmerge
    supports reading them (Matroska & MP4). The JSON identification format
    version number has been bumped to v15.
  * MKVToolNix GUI: multiplexer: added controls for all the video colour
    information & the video projection information.
  
  
  ## Bug fixes
  
  
  * mkvmerge: SRT reader: entries with a duration of 0 or less will now be
    skipped. Fixes #3332.
  * mkvpropedit, MKVToolNix GUI's chapter & header editors: fixed an invalid
    memory access when trying to update existing Matroska files whose EBML Head
    element had a "size" field length of eight bytes, and where rewriting said
    element would shrink the element by one byte. Files created by gstreamer fit
    the first part whereas the second depends on the changes requested by the
    user. Part of the fix of #3325.
  * mkvpropedit, MKVToolNix GUI's chapter & header editors: fixed the programs
    not handling having to remove EBML void elements at the end of the file
    correctly and consequently aborting. Part of the fix of #3325.
  * MKVToolNix GUI: the GUI now uses almost all SVG icons, allowing proper
    scaling even for scaling factors such as 125%. Fixes #3335.
  * MKVToolNix GUI: when compiled with Qt 5 the character set of INI files is
    forced to UTF-8 in order to fix reading INI files written by a version
    compiled with Qt 6. Fixes #3346.
  
  
  ## Build system changes
  
  
  * Qt's SVG library is now required.
