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: FLAC reader: pictures embedded into the FLAC file were already
    handled as attachments, but they were left in the codec initialization data
    as well. They're now removed from the codec initialization data. See #6079.
  * mkvmerge: FLAC reader: padding metadata blocks will now be removed from the
    codec initialization data. See #6079.
  * mkvmerge: FLAC reader: embedded Vorbis comments will now be converted into
    Matroska comments or track/global header fields when available (e.g. `TITLE`
    will become the segment title & track's name, `LANGUAGE` will become the
    track's language). Copying of Vorbis comments that are converted into actual
    Matroska tags can be prevented with the usual options,
    e.g. `--no-track-tags`. The comments will also be removed from the codec
    initialization data. Implements #6079.
  * mkvmerge, MKVToolNix GUI's chapter editor: when reading simple (OGM-style)
    chapter files & no character set is given for the file, mkvmerge will try
    UTF-8 first before falling back to the system's default encoding. Implements
    #6084.
  * MKVToolNix GUI: multiplexer: the special drag & drop zones added in v91 are
    now shown by default in new installations.
  * MKVToolNix GUI: in new installations the main window will now be sized at
    75% of the screen's resolution initially with a certain minimum initial
    size. This improves initial readability on high DPI screens that use screen
    scaling factors such as 150%.
  
  
  ## Bug fixes
  
  
  * mkvmerge: Ogg reader: during identification the track tags are now reported
    properly.
  * MKVToolNix GUI: multiplexer: within the "additional options", both
    track-specific ones & the global ones on the "Output" tab, it wasn't
    possible to specify empty (zero-length) arguments. With the intended syntax
    of two consecutive single or double quotation marks the empty arguments were
    simply skipped. This was fixed, and it is now possible to specify
    e.g. `--title ""` in the global "Additional options" in order to force no
    title to be written ever. Fixes #6087.
  
  
  ## Build system changes
  
  
  * Windows build: the `packaging/windows/populate_installer_dir.sh` now expects
    the user to pass the Saxon-HE's JAR file name to be passed with the `-s` or
    `--saxon-jar` parameter instead of the base directory for Saxon-HE. This
    allows newer versions of Saxon-HE to be used.
