Version 44.0.0 "Domino" 2020-03-08

New features and enhancements

• MKVToolNix GUI: header editor: the attachments can now be reordered via drag & drop. Implements #2753.

Bug fixes

• mkvmerge: Matroska reader: when encountering certain errors in the track headers such as the codec ID not being present mkvmerge will simply skip those tracks instead of exiting with an error. Fixes #2737.
• MKVToolNix GUI: multiplexer: the "ask before overwriting" functionality did not look for the correct file names when splitting was active. Fixes #2741.

Version 43.0.0 "The Quartermaster" 2020-01-26

New features and enhancements

• MKVToolNix GUI: using one of the command line options --info, --edit-headers or --edit-chapters will make the GUI select the corresponding tool on startup even if no further file name is given. Implements #2723.
• MKVToolNix GUI: multiplexer: added a setting in the preferences for changing the location of the MediaInfo executable for when the user accidentally selected the wrong one.

Bug fixes

• mkvmerge: AVC/h.264 parser: the order of the NALUs before each key frame was sometimes wrong: mkvmerge wrote SPS & PPS after SEI NALUs. Now SPS & PPS NALUs are always written before the other NALUs. Patch by Torsten Hauska. Part of the implementation of #2709 and part of the fix of #2250.
• mkvmerge: AVC/h.264 parser: when additional SPS or PPS NALUs (with IDs that haven't been seen so far) are found mid-stream, mkvmerge will prepend all following key frames with all current valid SPS & PPS NALUs (just like when SPS & PPS NALUs are overwritten mid-stream). Part of the fix of #2250.
• mkvmerge: MPEG TS reader: fixed detection of MPEG-1/2 video tracks consisting of very few frames. Fixes #2732.
• mkvmerge: Ogg Opus reader: fixed the handling of Ogg Opus streams that contain a just one Ogg page (mkvmerge aborted with an exception). Fixes #2722.
• MKVToolNix GUI: multiplexer: dragging & dropping XML files with chapters or tags to the GUI's window was broken in v42. Instead of adding the file names to the appropriate input boxes the GUI was running mkvmerge for file identification purposes which then failed. Fixes #2718.

Version 42.0.0 "Overtime" 2020-01-02

New features and enhancements

• mkvmerge: added an option for creating byte-identical files: --deterministic <seed>. Part of the implementation of #2698.
• mkvmerge: Matroska reader: mkvmerge will remove the icpf atom headers if they're present in frames read from Matroska files. Implements #2692.
• mkvmerge: MP4 reader: ALAC tracks: the number of channels, sampling frequency and bit depth are now taken from the bitstream in order to fix bogus values on the container level. Implements #2714.
• mkvpropedit: when changing track UIDs the referring elements in existing chapters & tags will be updated automatically, too. Part of the implementation of #2700.
• mkvinfo: when the option -p/--hex-positions is used, element positions will be output regardless of the verbosity level. Part of the implementation of #2713.
• mkvinfo: added the option -P/--positions for showing the position of each element in decimal regardless of the verbosity level used. Part of the implementation of #2713.
• mkvinfo: added the option -o/--continue for continuing processing when the first cluster is encountered regardless of the verbosity level used. Part of the implementation of #2713.
• mkvinfo: added the option -a/--all for outputting all sub-elements (even cues & seek head entries) and not stopping at the first cluster regardless of the verbosity level used. Part of the implementation of #2713.
• MKVToolNix GUI: multiplexer: added an option in the preferences for disabling adding cover images from Blu-ray discs. Implements #2693.
• MKVToolNix GUI: multiplexer: added mkvmerge's new --deterministic option in the "additional command-line options" dialog. Part of the implementation of #2698.
• MKVToolNix GUI: header editor:: when changing track UIDs the referring elements in existing chapters & tags will be updated automatically, too. Part of the implementation of #2700.

Bug fixes

• mkvmerge: HEVC ES parser: fixed a bug in the slice parser calculating the size of a field which in turn could have led to the slice's type being read wrong. Patch by Torsten Hauska. Fixes #2710.
• mkvmerge: Matroska reader: fixed a segmentation fault when trying to read a file that uses header removal compression but no removed bytes are present in the track headers. Fixes #2687.
• mkvmerge: MPEG elementary stream parser: fixed an invalid memory access and use of uninitialized memory that could happen under certain circumstances. Fixes #2690.
• mkvmerge: RealMedia reader: fixed a division by zero when all audio timestamps were zero. Fixes #2689.
• mkvmerge: RealMedia reader: fixed an invalid memory access in the video frame assembly code triggered by invalid data in the file. Fixes #2691.

Build system changes

• std::optional (C++17 feature) is now used instead of boost::optional.
• std::regex is now used instead of boost::regex.

Other changes

• New man page translations into French, Italian, Russian and Chinese Traditional have been added.
