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
  
  
  * all: IETF BCP 47/RFC 5646 language tags: when deriving the legacy language
    element codes to use a language tag's ISO 639 code is also potentially
    interpreted as an & its prefix is used as the legacy language code. For
    example, "Yue Chinese" = `yue` is not part of ISO 639-2. However, there is
    an extlang subtag `yue` with a valid prefix of `zh` ("Chinese"), and for
    "Chinese" there is an ISO 639-2 language code: `chi`. In this example the
    IETF language element would be set to `yue` and the corresponding legacy
    element to `chi`. Part of the implementation of #3307.
  * all: IETF BCP 47/RFC 5646 language tags: grandfathered language tags are now
    supported. Part of the implementation of #3307.
  * all: IETF BCP 47/RFC 5646 language tags: all deprecated subtags from the
    IANA language subtag registry are now supported. Part of the implementation
    of #3307.
  * all: IETF BCP 47/RFC 5646 language tags: all lists of valid subtags have
    been updated from their respective authoritative sources. Part of the
    implementation of #3307.
  * all: IETF BCP 47/RFC 5646 language tags: all in the IANA language subtag
    registry are now supported, even those marked as deprecated and of type
    'grandfathered'. Part of the implementation of #3307.
  * all: IETF BCP 47/RFC 5646 language tags: reduced the maximum number of
    extended language subtags that are present in a valid tag from 3 to 1 in
    compliance with RFC 5646 section 2.2.2. Part of the implementation of #3307.
  * all: IETF BCP 47/RFC 5646 language tags: all language codes reserved for
    private/local use (`qaa`–`qtz`) are now supported. Part of the
    implementation of #3307.
  * all: IETF BCP 47/RFC 5646 language tags: Digital Cinema Naming Convention
    language codes that fall into the IETF BCP 47 range of "private use" tags
    (`qaa`–`qtz`) are now replaced by their IETF BCP 47 equivalents during
    normalization (e.g. `QMS` → `cmn-Hans`). Part of the implementation of
    #3307.
  * all: added a new translation to Chinese Simplified (Singapore) by Dian Li.
  * mkvmerge, mkvpropedit: added a new command line option called
    `--enable-legacy-font-mime-types`. With this option on the two programs will
    use the same legacy MIME types for fonts whenever new attachments are added
    (both programs), when reading existing attachments (only `mkvmerge`) or when
    replacing existing ones (only `mkvpropedit`).
  * mkvmerge, mkvpropedit: IETF BCP 47/RFC 5646 language tags: added a command
    line option `--normalize-language-ietf <mode>` which turns on normalization
    of IETF BCP 47 language tags to either their canonical (mode `canonical`) or
    extended language subtags form (mode `extlang`) or turns it off (mode
    `off`). If the option isn't given, language tags will now be normalized to
    the canonical form. Part of the implementation of #3307.
  * MKVToolNix GUI: IETF BCP 47/RFC 5646 language tags: ISO 639-3 and 639-5
    languages will now be used by default. Part of the implementation of #3307.
  * MKVToolNix GUI: IETF BCP 47/RFC 5646 language tags: the language editor
    dialog will now show warnings in several cases: when deprecated tags are
    used; when the tag's canonical and/or extlang forms differ from the user
    input. Part of the implementation of #3307.
  * MKVToolNix GUI: IETF BCP 47/RFC 5646 language tags: the language editor now
    has a button to replace the current tag with a normalized form (canonical or
    extlang) if those differ from the current tag. Part of the implementation of
    #3307.
  * MKVToolNix GUI: IETF BCP 47/RFC 5646 language tags: added an option in the
    preferences to always normalize all language tags to their canonical or
    extlang forms or to turn normalization off. Can also be enabled from the
    language editor dialog. Part of the implementation of #3307.
  * MKVToolNix GUI: IETF BCP 47/RFC 5646 language tags: the language dialog now
    shows a warning if a variant is used with a prefix that isn't in the
    variant's list of suitable prefixes. It'll also say if the corresponding
    canonical/extlang forms would have a suitable prefix. Part of the
    implementation of #3307.
  * MKVToolNix GUI: IETF BCP 47/RFC 5646 language tags: the language dialog now
    shows a warning if a script is used with a language for which it should be
    suppressed. Part of the implementation of #3307.
  * MKVToolNix GUI: multiplexer: the track property group boxes in the
    scrollable pane are now collapsible & expandable, saving their state over
    restarts of the GUI. This is in preparation of adding many more track
    properties in future releases, allowing the user to hide parts they don't
    use all that often.
  * MKVToolNix GUI: multiplexer: if the option "use legacy font MIME types" is
    enabled in the preferences, the new command line option
    `--enable-legacy-font-mime-types` will be passed to `mkvmerge` in order to
    have it remap the MIME types of existing attachments, too.
  
  
  ## Bug fixes
  
  
  * all: IETF BCP 47/RFC 5646 language tags: variants aren't validated wrt. to
    prefixes anymore as BCP 47 doesn't actually pose restrictions on them,
    saying only that prefixes "are suitable sequences" for use with the
    variants. What is now verified, though, is that no variant is used multiple
    times within the same language tag. Part of the implementation/fix of #3307.
  * build system & MKVToolNix GUI: fixed detecting the presence of & the
    compilation with the multimedia module of Qt version 6.2.0 and newer.
  * build system: fixed compilation on Unices other than Linux & macOS
    (e.g. FreeBSD). Fixes #3316.
  * MKVToolNix GUI: job queue: fixed compiling in the audio player code for the
    the "play audio" end-of-job action. Fixes #3303.
  * MKVToolNix GUI: multiplexer: recognizing added XML chapter, segment info or
    chapter files required the XML declaration & root node (e.g. `<?xml…?> …
    <Chapters>` for chapters) be located within the first 1 KB, which wasn't
    enough for files that contain a lot of comments at the start like the
    included `example-chapters-2.xml`. The detection range was extended to 10
    KB. Fixes #3302.
  
  
  ## Build system changes
  
  
  * build system: the provided Windows binaries are now compiled with Qt 6. A
    drawback is that certain audio formats aren't supported anymore by Qt for
    the "end of job" sound notification playback, notably the Ogg file format &
    the Vorbis audio codec. MKVToolNix therefore now ships Opus-in-WebM files
    for the same purpose.
  * The bundled `fmt` library was updated to v8.1.1.
  * The bundled `nlohmann-json` library was updated to v3.10.5.
  * The bundled `pugixml` library was updated to v1.12.1.
