MKVToolNix v53.0.0 released

Heydiho,

trying to keep up my usual schedule in 2021 of about four to five weeks between releases. This time it’s even a bit less than four weeks. Several bug fixes and small enhancements were made.

There have been no changes for package maintainers.

You can download the source code or one of the binaries. The Windows and macOS binaries as well as the Linux AppImage are available already. The other Linux binaries are stil being built and will be available over the course of the next couple of hours.

Here are the NEWS since the previous release:

New features and enhancements

  • mkvmerge: AVI reader: added support for reading the video aspect ratio from the video properties header (vprp chunk) if present and setting the display dimensions accordingly. Implements #2993.
  • mkvmerge: MP4 reader: for h.264/AVC tracks that don’t have an AVCConfigurationBox (avcC atom) in their sample description (stsd) atom or whose avcC atom contains no content mkvmerge will now re-derive the AVCConfigurationBox from the bitstream. Implements #2995.
  • mkvextract: mkvextract will now check if any of the destination file names is the same as the source file name and abort with an error if that’s the case. Implements #3001.
  • MKVToolNix GUI: when querying the user for a file name for saving things (e.g. multiplexer settings or an attachment in the header editor), the automatically suggested file name will now be based on the situation-specific file names (e.g. the destination file name for multiplexer settings or the attachment’s name when saving an attachment in the header editor) instead of the directory’s name. Implements #3012.
  • MKVToolNix GUI: multiplexer: when deriving track languages from file names the GUI will now select the right-most match instead of the left-most one. For example, "La.vie.en.rose.(fr).srt" will now be detected as French (fr) instead of English (en). Implements #3013.
  • MKVToolNix GUI: preferences: the items in the "pre-defined …" lists can now be renamed by double-clicking with the mouse or pressing the F2 key.
  • Windows installer: the bluray_dump command-line utility will be installed into the tools sub-directory. bluray_dump can read & dump certain file types used on Blu-rays: .mpls playlists, .clpi clip information databases, .bdmv index files, bdmt_….xml disc library databases and tnmt_….xml track & chapter name databases.

Bug fixes

  • mkvmerge: stretching chapter timestamps with --chapter-sync now works correctly with floating point values including fractions of floating point numbers (e.g. 12.3/45.67). The tooltips in the GUI have been adjusted accordingly. Fixes #3002.
  • mkvmerge: MPEG 1/2 video handling: the "default duration" header field was often half the value it actually should be, resulting in all video frames having an explicit block duration with the correct value. This has been fixed with a patch by Tom Yan.
  • mkvmerge: MPEG 1/2 video handling: the data stored in Codec private and Codec state doesn’t contain extensions other than sequence & sequencea display extensions anymore. Fix by Tom Yan.
  • mkvmerge: tag handling: when remuxing a Matroska file with the --no-track-tags, existing SOURCE_ID track tags are now skipped, too.
  • MKVToolNix GUI: multiplexer: the drop-down boxes with pre-defined track names now follow the order set in the preferences instead of sorting the entries alphabetically. Fixes #2999.

Have fun :)

    I hope that I am not violating any protocols by asking you this question. I am *very* new to blog posting in general :)

    I am trying to locate an open-source replacement to DVD Shrink to make copies of my original DVD’s to blank DVD’s. Would your utility work for this?

    If not, any suggestions for an alternative utility?

      HandBrake & vobcopy are two examples of programs that should be able to handle DVDs. Not sure about _creating_ DVDs, though; I never do that.

    Hello!
    I love the Tools you are creating! your dong a great job!

    is there any way you can add something that shows the total time of all the videos you have in a list? so that way you know how long in total combined video will be?

    also, is there any way the videos can be wrapped in a mp4 wrapper?

    Thank You So Much!

      > is there any way you can add something that shows the total time of all the videos you have in a list? so that way you know how long in total combined video will be?

      That’s technically very difficult and therefore nothing I’m going to implement. For one, a lot of container formats actually do not provide information about the length of the content, and even if they do, often only about the overall length but not the length of each track. The total length also depends on the command line options used during muxing (e.g. which tracks you’re muxing and whether or not you’re using the splitting option). In short, it would often require parsing all input files from beginning to end, something that takes a lot of time.

      MKVToolNix is all about Matroska. There are different tools for creating MP4 files.
