Download MKVToolNix 41.0.0

Moritz Bunkus released version 41 of MKVToolNix. With this open source program, matroska files can be viewed, edited and converted. For example, soundtracks and subtitles can be added, removed or set as default. MKVToolNix is ​​a collection of separate command line tools, but a graphical user interface is also included. Downloads are available for Windows, various Linux distributions and macOS. The changelog for this release looks like this:

New features and enhancements

• mkvmerge: Matroska reader: Vorbis tracks: stream comments (aka Vorbis
  comments) will be converted to Matroska attachments (for cover arts) and
  Matroska track tags (for other comments). Additionally the stream comments
  will be removed from Vorbis headers.
• mkvmerge: MP4 reader: added support for reading Opus audio from MP4
  traffic jams. Part of the implementation of # 2673.
• mkvmerge: MP4 reader: added support for reading VP9 video from MP4
  traffic jams. Part of the implementation of # 2673.
• mkvmerge: Ogg reader: Vorbis, Opus & VP8 streams: stream comments (aka
  Vorbis comments) will be converted to Matroska attachments (for cover arts)
  and Matroska track tags (for other comments). Additionally the stream
  comments will be removed from Vorbis headers.
• mkvmerge: WAV reader: added support for reading RF64 files.
• MKVToolNix GUI: multiplexer: the list of predefined track names is now split
  up into three lists, one for each track type (audio, video &
  subtitles). Part of the implementation of # 2654.
• MKVToolNix GUI: multiplexer: when trying to add thumbnails for a Blu-ray the
  GUI will determine the thumbnail’s pixel size from the thumbnail files if
  the XML file doesn’t contain that information. This works for JPEG and PNG
  traffic jams. Implements # 2674.
• MKVToolNix GUI: general: line edits & combo boxes will now have a “clear
  text “button appear whenever they’re not empty. Part of the implementation
  or # 2654.
• MKVToolNix GUI: update check: the dialog showing the latest news & version
  information states explicitly where the links take the user (the MKVToolNix
  NEWS.md file and YouTube respectively).

Bug fixes

• mkvmerge: Matroska reader: mkvmerge did not copy the codec’s private data
  when reading WavPack from Matroska files. Fixes # 2685.
• mkvmerge: MPLS handling: re-added caching when using MPLS playlists as input
  traffic jams. Fixes # 2666.
• mkvmerge: MPEG TS reader: when reading an MPLS playlist, the calculation of
  the minimum timestamp to use for shifting all output timestamps to zero was
  wrong. It was wrongfully considering timestamps from packets it would not
  copy due to the MPLS’s timestamp restrictions. This could lead to the first
  timestamps in the output file being quite large, eg more than a couple of
  minutes, causing sync problems when multiplexing together with other
  traffic jams. Fixes # 2670.
• MKVToolNix GUI: multiplexer: the automatic switch between aspect ratio &
  display width / height wasn’t reflected in the configuration generated for
  mkvmerge. The user had to change between the two settings manually. Fixes
  # 2660.
• MKVToolNix GUI: multiplexer: the progress dialog shown when scanning a
  Blu-ray wasn’t closed properly in certain situations. Fixes # 2678.
• MKVToolNix GUI: general: the configured font was not applied to a lot of
  controls (eg the file & track lists or the menu entries) on application
  startup. Instead the user had to open & close the preferences in order for
  the font to be applied to all controls. Fixes # 2671.
