MKVToolnix 61.0.0 “So”

MKVToolNix is the one of the best collection of tools (mkvmerge, mkvinfo, mkvextract, mkvpropedit and mmg) for modifying MKV files.

With these tools one can get information about (via mkvinfo) Matroska files, extract tracks/data from (via mkvextract) Matroska files and create (via mkvmerge) Matroska files from other media files. Matroska is a new multimedia file format aiming to become THE new container format for the future. You can find more information about it and its underlying technology, the Extensible Binary Meta Language (EBML), at http://www.matroska.org

The graphical user interface (GUI) allows you to manipulate Matroska (MKV) files in several ways. You can use those tools to create, split, edit, mux, demux, merge, extract or inspect Matroska files.

MKVToolnix will also work with other video formats. Such as AVI, MPEG, MP4, MPEG, Ogg/OGM, RealVideo, MPEG1/2, H264/AVC, Dirac, VC1.

And more as well as some video codecs such as VP9 video codec support – reading from IVF, Matroska, WebM files, extract to IVF files.

Moreover the program can work with audio files such as AAC, FLAC, MP2, MP3, AC3, DTS/DTS-HD, Vorbis, RealAudio. And also work with most subtitle formats including SRT, PGS/ SUP, VobSub, ASS, and SSA.

It is a cross-platform application that will work on Microsoft Windows (both 32 and 64-bit versions), Apple macOS and Linux operating systems.

Here is also the portable version which does not require installation. You just need to start the function. It can also be stored on external devices and run on any computer you have access to.

Changes in MKVToolnix 61.0.0 “So” (2021-08-30):

Changes in MKVToolnix 60.0.0 “Are We Copies?” (2021-07-31):

New features and enhancements

  • all: IETF BCP 47/RFC 5646 language tags: added support for language families from ISO 639-5 that aren’t part of 639-2.
  • all: IETF BCP 47/RFC 5646 language tags: implemented support for Alpha 2 country codes of the “user-defined” category: `AA`, `QM`–`QZ`, `XA`–`XZ` and `ZZ`.
  • all: IETF BCP 47/RFC 5646 language tags: updated the various lists of valid subtags from the official specs.
  • MKVToolNix GUI: multiplexer: pressing the keyboard shortcut for the track’s “Language” label (Alt+L for English) will now open the language dialog.
  • MKVToolNix GUI: multiplexer: added an option in the preferences for turning off the colored boxes indicating which file each track belongs to.

Bug fixes

  • all: IETF BCP 47/RFC 5646 language tags: fixed validating extended language & variant subtags against their allowed prefixes (e.g. a valid tag with a country code as in `de-CH-1996` is recognized as valid while two generally known variants that aren’t allowed together as in `de-1901-1996` is recognized as invalid).
  • all: IETF BCP 47/RFC 5646 language tags: when looking up a language for a two- or three-letter code, the programs will no longer compare that code with language names as that was unintended, ambiguous (e.g. the code “Ga” could be interpreted as the 639-2 alpha-2 code for “Irish” or as the name of the language called “Ga”) and only worked with languages whose name was at most three letters long.
  • mkvmerge: HEVC/H.265: appending Matroska files with HEVC tracks might lead to the loss of the first couple of frames from each of the second and all following files.
  • mkvmerge, mkvextract: HEVC/H.265 parser: fixed the programs aborting when parsing VPS or SPS NALUs with invalid content due to unhandled exceptions.
  • MKVToolNix GUI: multiplexer: when the option “use legacy MIME types for font attachments” is enabled, the GUI will now use `application/x-truetype-font` for font collection files.
  • MKVToolNix GUI: multiplexer: fixed escaping the `mkvmerge` argument in the “Show command-line options” dialog for the “Windows (cmd.exe)” mode.
  • MKVToolNix GUI: multiplexer: when adding multiple files at once, the GUI will sort file names with numbers the way a human would expect it to. For example, `1.mp4`, `9.aac`, `10.srt`, `11.srt` are now sorted exactly that order instead of `1.mp4`, `10.srt`, `11.srt`, `9.aac`.
  • MKVToolNix GUI: header editor: the header editor will now honor the “use legacy MIME types when adding font attachments” setting when adding new attachments.

Changes in MKVToolnix 57.0.0 “Till The End” (2021-05-22):

New features and enhancements

  • mkvmerge: MP4 reader: added support for reading Dolby Vision from MP4 files (FourCCs `dvh1` and `dvhe`; configuration records `dvcC`, `dvvC` and `hvcE` will be converted into block addition mappings).
  • mkvmerge: SRT subtitles: mkvmerge now accepts empty text files with the extension `.srt` as SRT subtitle files, enabling the creation of empty SRT tracks.
  • mkvmerge, mkvextract: HEVC/H.265: access unit delimiter NALUs will no longer be discarded, neither during muxing nor during extraction.
  • MKVToolNix GUI: preferences: switched the order & wording of controls in the “enabling items” panel to make it clearer that certain controls define exceptions.

Bug fixes

  • mkvmerge: HEVC/H.265 parser: several NALU types, notably the Dolby Vision-specific NALUs (“unspecified 62” and “unspecified 63”) and suffix SEI NALUs, are now stored with the frame they belong to instead of with the next frame.
  • mkvmerge: HEVC/H.265 packetizer: fixed setting the track’s default duration when reading HEVC/H.265 from Matroska files that don’t have a default duration set.
  • mkvmerge: HEVC/H.265 packetizer: fixed the calculation of the duration of frames so that `SimpleBlock` elements can be used again instead of `BlockGroups` with `BlockDuration` elements.
  • mkvmerge, mkvextract: HEVC/H.265 parser: fixed issues with ordering & duplication of certain NALUs (parameter set & prefix SEI NALUs).
  • MKVToolNix GUI: multiplexer: when dragging & dropping files to the multiplexer, the source directory will be remembered as the “last open
    directory” again, causing subsequent uses of the “open file” dialog to start in the same directory.
  • mkvinfo: fixed the position of frames in block groups containing “block duration” elements in summary mode (e.g. for subtitle tracks).

Build system changes

  • `configure` will now try to detect `libmagic` via `pkg-config` and fall back to including & linking directly if it cannot be found via `pkg-config`.

Changes in MKVToolnix 56.1.0 “My Friend” (2021-04-09):

New features and enhancements

  • mkvmerge: AAC: added support for LOAS/LATM files with channel configuration indexes 9–21 (e.g. channel count 22.2 for index 13) according to Rec. ITU-R BS.1196-7 & ISO/IEC 23008-3:2019. Fixes #3081.

Bug fixes

  • mkvmerge: HEVC/H.265 parser: fixed invalid memory access that could happen when reading certain types of HEVC data (e.g. with changing parameter sets mid-stream) from certain containers (e.g. Matroska). This bug was introduced in release 56.0.0. Fixes #3083.
  • mkvextract: AAC: mkvextract will now abort with an useful error message when the user tries to extract a track whose ‘audio-specific config’ element in `CodecPrivate` signals a number of channels of 7 or greater than 8 as that isn’t supported by the ADTS format.

Build system changes

  • configure: the `–enable-ubsan` option hasn’t actually enabled anything since release 39.0.0.
