Moritz Bunkus heeft versie 29 van MKVToolNix uitgebracht. Met dit opensourceprogramma kunnen matroska-bestanden bekeken, bewerkt en worden geconverteerd. Zo kunnen geluidssporen en ondertiteling worden toegevoegd, verwijderd of juist als standaard worden ingesteld. MKVToolNix is een verzameling afzonderlijke commandline-tools, maar er wordt ook een grafische gebruikersinterface meegeleverd. Downloads zijn beschikbaar voor Windows, diverse Linux-distributies en macOS. De changelog voor deze uitgave ziet er als volgt uit:
Important notesNew features and enhancements
- The string formatting library used was switched from
boost::format
tofmt
. See the section "Build system changes" for details.Bug fixes
- MKVToolNix GUI: added an option in the preferences for disabling automatic scaling for high DPI displays. Implements #2415.
- MKVToolNix GUI: the GUI will now prevent the system from going to sleep while the job queue is running. This feature is implemented for macOS, Windows and Linux/Unix systems where the
org.freedesktop.login1.Manager
D-Bus interface is available. Implements #2411.Build system changes
- mkvmerge: chapter generation: the start timestamps of chapters generated in intervals was wrong for files whose smallest video timestamp was bigger than 0. Fixes #2432.
- mkvmerge: MP4 reader: fixed handling of atoms whose size exceeds the parent atom’s size. Fixes #2431.
- mkvmerge, MKVToolNix GUI’s chapter editor: the chapter name template will now also be used when reading Ogg-style chapter files with empty chapter names. Fixes #2441.
- mkvextract: AAC: mkvextract will now write the program config element (PCE) before the first AAC raw data packet if the PCE is present in the
AudioSpecificConfig
structure in theCodec Private
Matroska element. The PCE carries vital information about the number of channels and is required in certain cases. Fixes #2205 and #2433.- mkvpropedit, MKVToolNix GUI’s header editor: in situations when a one-byte space must be covered by a new EBML void element the following element must be moved up instead. If that moved element is a cluster, the corresponding cue entries will now be updated to reflect the cluster’s new position. Fixes #2408.
- MKVToolNix GUI: Windows: the application manifest is now included properly so that Windows actually recognizes it. See #2415.
- Qt’s D-Bus implementation is now required for building on systems other than macOS and Windows,
- The
boost::format
library is not used anymore.- The
fmt
library is now required. Versions 3 and newer are supported. As not all Linux distributions include packages for the library, its release 5.2.1 comes bundled with MKVToolNix. Theconfigure
script will check for a system version of the library and use it if present and recent enough. Otherwise it will fall back to the bundled version and link that statically.
