MKVToolNix (64-bit)

What's new in this version:

New features and enhancements:
- mkvmerge: Matroska reader: Vorbis tracks: stream comments (aka Vorbis comments) will be converted to Matroska attachments (for cover arts) and
Matroska track tags (for other comments). Additionally the stream comments will be removed from Vorbis headers
- mkvmerge: MP4 reader: added support for reading Opus audio from MP4 files
- mkvmerge: MP4 reader: added support for reading VP9 video from MP4 files
- mkvmerge: Ogg reader: Vorbis, Opus & VP8 streams: stream comments (aka Vorbis comments) will be converted to Matroska attachments (for cover arts)
and Matroska track tags (for other comments). Additionally the stream comments will be removed from Vorbis headers
- mkvmerge: WAV reader: added support for reading RF64 files
- MKVToolNix GUI: multiplexer: the list of predefined track names is now split up into three lists, one for each track type (audio, video & subtitles)
- MKVToolNix GUI: multiplexer: when trying to add thumbnails for a Blu-ray the GUI will determine the thumbnail's pixel size from the thumbnail files if the XML file doesn't contain that information. This works for JPEG and PNG files
- MKVToolNix GUI: general: line edits & combo boxes will now have a "clear text" button appear whenever they're not empty
- MKVToolNix GUI: update check: the dialog showing the latest news & version information states explicitly where the links take the user (the MKVToolNix NEWS.md` file and YouTube respectively)

Bug fixes:
- mkvmerge: Matroska reader: mkvmerge did not copy the codec's private data when reading WavPack from Matroska files
- mkvmerge: MPLS handling: re-added caching when using MPLS playlists as input files
- mkvmerge: MPEG TS reader: when reading an MPLS playlist, the calculation of the minimum timestamp to use for shifting all output timestamps to zero was
wrong. It was wrongfully considering timestamps from packets it would not copy due to the MPLS's timestamp restrictions. This could lead to the first timestamps in the output file being quite large, e.g. more than a couple of minutes, causing sync problems when multiplexing together with other
files
- MKVToolNix GUI: multiplexer: the automatic switch between aspect ratio & display width/height wasn't reflected in the configuration generated for
mkvmerge`. The user had to change between the two settings manually
- MKVToolNix GUI: multiplexer: the progress dialog shown when scanning a Blu-ray wasn't closed properly in certain situations
MKVToolNix GUI: general: the configured font was not applied to a lot of controls (e.g. the file & track lists or the menu entries) on application startup. Instead the user had to open & close the preferences in order for the font to be applied to all controls
