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: MP4 reader: added support for BMP covert art images.
  * MKVToolNix GUI: multiplexer: added an option to disable deriving the
    destination file name from the file title. Implements #2648.
  * MKVToolNix GUI: multiplexer: the content of the "stereoscopy" combo box has
    been simplified making the box's minimum width much smaller, allowing the
    user to resize the GUI's whole window to a much smaller width.
  * MKVToolNix GUI: multiplexer: whenever the user changes the "aspect ratio" or
    "display dimensions" controls, the corresponding radio button will be
    activated automatically. Implements #2651.
  * MKVToolNix GUI: Windows: added a setting in the preferences to disable the
    GUI's dark color mode even if Windows's app color mode is set to
    dark. Implements #2646.
  * MKVToolNix GUI: Windows: replaced the dark mode introduced in v39 with
    another dark mode that's less wasteful with space between widgets.
  
  
  ## Bug fixes
  
  
  * mkvmerge: MP4 reader: mkvmerge was reading eight bytes too many for cover
    art images. This could cause file identification to fail when the cover art
    was located at the end of the MP4 file. Even if it succeeded, this meant too
    much data present in the attachment. Fixes #2650.
  * mkvmerge: MP4 reader: covert art images with unknown image types will be
    skipped instead of treated as JPEG images.
  
  
  ## Build system changes
  
  
  * Qt 5.9.0 or newer is now required for building MKVToolNix GUI.
