New features and enhancements:
Mkvmerge: track statistics tags: the TagDefault element will not be written anymore as it was always set to the default value 1 anyway.
Mkvmerge, MKVToolNix GUI: JSON files can now contain C++-style line comments outside of strings (e.g. something like this: // this is ignored). Such comments, even though not part of the official JSON specifications, are now ignored when reading JSON files.
MKVToolNix GUI: chapter editor: opening a Matroska file without chapters in it will now open the file in an empty chapter editor instead of showing an error message.
MKVToolNix GUI: an "info" tool has been added, replacing the functionality of mkvinfo’s GUI. The functionality is not on par yet but will be for release v22.
Bug fixes:
Build system: configure was treating --disable-ubsan and --disable-addrsan the same as --enable-ubsan and --enable-addrsan.
Build system: an error message is output if a command to execute is not found instead of silently failing.
Build system: in addition to looking for the gettext C function and library, configure now also verifies the presence of the msgfmt program instead of simply relying on it.
Mkvmerge: appending files with additional parts at the same time was broken if more than one additional part was appended (e.g. when appending files from DVDs with something like '(' VTS_01_1.VOB VTS_01_2.VOB ')' + '(' VTS_02_1.VOB VTS_02_2.VOB ')'). In such a situation the content from files VTS_02_1.VOB and VTS_02_2.VOB where laid out in parallel to the content from the earlier files.
Mkvmerge: FLV reader: a single invalid AAC frame was written for AAC audio tracks with codec initialization data longer than five bytes.
Mkvmerge: FLV reader: timestamps will be normalized down to 0.
Mkvmerge: MP4 reader: if an AAC track doesn’t contain an AAC-specific decoder configuration in the ESDS portion, then a default decoder configuration will be generated based on the track’s header data instead of skipping the track.
Mkvmerge: MP4 reader: fixed reading HEVC/h.265 video tracks if they’re stored as Annex B byte streams inside MP4.
Mkvmerge: Ogg Opus reader: mkvmerge will now emit a warning instead of aborting when it encounters an Ogg Opus page with no data in the packet.
Mkvmerge, mkvextract: Matroska parser: fixed a segmentation fault that occurred whenever the first level 1 element after resyncing after an error in the file structure isn’t a cluster.
Mkvmerge, MKVToolNix GUI multiplexer & header editor: fixed a crash during file type detection for attachments if MKVToolNix is installed in a path with non-ASCII characters (e.g. German Umlauts).
Mkvinfo: the --hex-positions parameter did nothing in summary mode.
Mkvinfo: Windows: line endings will be written as \r (carriage return & line feed) again instead of just (line feed).
Mkvpropedit: adding track statistics tags: for tracks with content encoding (compression) mkvpropedit is now accounting the uncompressed number of bytes, not the encoded (compressed) number of bytes.
MKVToolNix GUI: multiplexer: the subtitle character set can now be set for appended subtitle files, too.
MKVToolNix GUI: multiplexer: when appending, all tracks appended to disabled tracks will start out disabled, too.
Build system changes:
Mkvinfo: the GUI portion has been removed. mkvinfo is now a pure command-line program again.
