Versie 7.4.0 van MKVToolNix is uitgekomen. MKVToolNix is een verzameling opensourceprogramma's waarmee Matroska-bestanden kunnen worden bekeken, bewerkt en geconverteerd. Zo kunnen geluidssporen en ondertiteling worden toegevoegd, verwijderd of juist als standaard worden ingesteld. Het zijn afzonderlijke commandline-tools, maar er wordt een grafische gebruikersinterface meegeleverd. Versies kunnen worden gedownload voor Windows, een groot aantal Linux-distributies en OS X. In deze release zijn de volgende veranderingen en verbeteringen aangebracht:
Release v7.4.0
- mkvmerge: bug fix: mkvmerge was sometimes dropping lines from teletext subtitles read from MPEG transport streams. See #773.
- mkvmerge: bug fix: The PCM packetizer was producing wrong track statistics by disregarding the last packet's duration when reading PCM data from packaged sources (Matroska, MP4 files). Fixes #1075.
- build system: enhancement: configure will look for a system version of the pugixml library and use that instead of the bundled version if it is found. Fixes #1090.
- mkvextract: bug fix for chapter & tag extraction: If locale is set to a non-UTF locale (including C or POSIX) then no XML data was output at all even if the XML data contained ASCII characters only. Fixes #1086. This also fixes mkvextract writing two BOMs when extracting tags with the »--redirect-output« option on Windows.
- mkvinfo: bug fix: summary mode: reported frame types in block groups are now derived from the number of references found and not by the references' values.
- mkvmerge: bug fix: Fixed muxing open GOPs after I frames in MPEG-1/2 video (patch by Stefan Pãschel). Fixes #1084.
- mmg: bug fix: VP9 video tracks are accepted in WebM mode.
- mkvmerge: bug fix: Cherry-picked several commits from DivX' mkvmerge fork for improved HEVC handling. Fixes #1076.
- all: new feature: added a Catalan translation of the programs by Antoni Bella Pãrez
- mkvmerge: bug fix: Fixed the handling of Big Endian PCM tracks read from MP4 files. Fixes #1078.
