MKVToolNix 46.0.0

[Karamjit]

MKVToolNix is a small collection of tools (mkvmerge, mkvinfo, mkvextract, mkvpropedit and mmg) with a GUI that allows you to manipulate Matroska (MKV) files in several ways. You can use MKVToolNix to create, split, edit, mux, demux, merge, extract or inspect Matroska files. The program will also work with other video formats (AVI, MPEG, MP4, MPEG, Ogg/OGM, RealVideo, MPEG1/2, h264/AVC, Dirac, VC1) including some video codecs (such as VP9 video codec support - reading from IVF/Matroska/WebM files, extract to IVF files). Audio formats (AAC, FLAC, MP2, MP3, (E)AC3, DTS/DTS-HD, Vorbis, RealAudio) and also most subtitle formats (SRT, PGS/SUP, VobSub, ASS, SSA, etc.). MKVToolNix is a cross-platform application that will work on Windows (both 32 and 64-bit versions), Mac OS X and Linux.

In This Release:

New Features:

• mkvmerge: when splitting, the placeholder `%c` can be used in the destination file name. It'll be replaced by the name of the first chapter in the file.
• mkvmerge: when reading MPLS playlists mkvmerge will include a tag named`SOURCE_ID` in the track's statistics tags that conveys the fact that the source was a Blu-ray and what the track's ID was in the source container. When reading Matroska file existing `SOURCE_ID` tags will be kept. The format used is the same format MakeMKV uses.
• mkvmerge: for audio-only files mkvmerge will now write a cue entry every 500ms instead of every 2s.
• MKVToolNix GUI: job actions: split up the option "execute when the job finishes successfully or with warnings" into two separate options: "…when finishes successfully" and "…when exits with warnings".

Bug fixes:

• mkvmerge: Matroska reader: when regenerating UIDs for chapters mkvmerge will  now fix referencing tag chapter UID targets to have the same values.
• mkvmerge: MP4 reader: fixed a crash that could potentially happen while trying to identify H.265/HEVC tracks.
• mkvmerge: MP4 reader: when reading H.265/HEVC tracks without a frame offset table (`ctts` atom) present, mkvmerge did not parse the `hevcC` structure correctly in certain cases, causing no video frames to be output at all or the output not being playable.
• mkvmerge: MPLS handling/MPEG TS reader: timestamp restrictions as given in an MPLS file were only honored for the first play item, not for subsequent play items. For those play items the whole referenced file was always copied.
• mkvmerge: MPLS handling/MPEG TS reader: under certain circumstances mkvmerge copied one frame too many before switching to the next play item.
• mkvmerge: for audio-only files cues will only be created for I frames (important for e.g. TrueHD where decoding can only start on a sync frame).
• MKVToolNix GUI: fixed a crash that happened when closing the preferences after having closed at least one multiplexer tab.
• MKVToolNix GUI: macOS: changed the default of the "elide tab header labels" feature introduced in v45 from "no" to "yes" to mirror how versions before v45 behaved on macOS.
