MKVToolNix is a set of tools that include mkvmerge, mkvinfo, mkvextract, mkvpropedit and mmg, which allow you to to create, manipulate and inspect Matroska (.MKV) files in several ways. With MKVToolNix you can create, split, edit, mux, demux, merge, extract or inspect Matroska files. Supported formats include:. Video formats: AVI, MPEG, MP4, MPEG, Ogg/OGM, RealVideo, MPEG1/2, h264/AVC, Dirac, VC1. Supported video codecs include VP9. Audio formats: AAC, FLAC, MP2, MP3, (E)AC3, DTS/DTS-HD, Vorbis, RealAudio.
Subtitle formats: SRT, PGS/SUP, VobSub, ASS and SSA. MKVToolNix is a cross platform application, which is also available for Windows and Linux. System Requirements: Mountain Lion (10.8) and Mavericks (10.9). New features and enhancements: Mkvmerge: SRT/ASS/SSA text subtitles: for files for which no encoding has been specified, mkvmerge will try UTF-8 first before falling back to the system's default encoding. Mkvmerge: SRT/ASS/SSA/WebVTT text subtitles: a warning is now emitted if invalid 8-bit characters are encountered outside valid multi-byte UTF-8 sequences. Mkvmerge: Matroska & MPEG transport stream readers: the encoding of text subtitles read from Matroska files can now be changed with the `-sub-charset` parameter. Linux: starting with release 25 an AppImage will be provided which should run on any Linux distribution released around the time of CentOS 7/Ubuntu 14.04 or later.
MacOS: translations: updated the `build.sh` script to build `libiconv` and a complete `gettext`. Together with an additional fix to how translation files are located, MKVToolNix can now use all interface languages on macOS, too. Bug fixes: Mkvmerge: AVC/h.264: fixed file identification failing for certain elementary streams due to internal buffers not being cleared properly. Mkvmerge: HEVC/h.265: fixed file identification failing for certain elementary streams due to internal buffers not being cleared properly.
This is the HEVC analog to what was fixed for AVC. Mkvmerge: MLP code: fixed various issues preventing MLP from being parsed correctly. Mkvmerge: TrueHD/MLP packetizer; dialog volume normalization removal isn't attempted if the track is an MLP track as the operation is only supported for TrueHD, not MLP. Mkvmerge: MPEG TS reader: when reading MPLS mkvmerge will now compare the MPLS's start and end timestamps against the transport stream's PTS instead of its DTS. Otherwise the first key frame of a video track might be dropped if it isn't the first in presentation order.
Mkvmerge: JSON identification: mkvmerge will ensure that all strings passed to the JSON output modules are valid UTF-8 encoded strings by replacing invalid bytes with placeholder characters. This avoids the JSON library throwing an exception and mkvmerge aborting on such data. Mkvmerge: audio packetizers: mkvmerge will now keep discard padding values if they're present for packets read from Matroska files. Mkvmerge: Ogg Opus reader: packet timestamps aren't calculated by summing up the duration of all packets starting with timestamp 0 anymore.
Instead the algorithm is based on the Ogg page's granule position and which packet number is currently timestamped (special handling for the first and last packets in the stream). This fixes the first timestamp if the first Ogg packet's granule position is larger than the number of samples in the first packet (= if the first sample's timestamp is bigger than 0). Mkvmerge will keep those offsets now and inserts 'discard padding' only where it's actually needed.
It also improves handling of invalid files where the first Ogg packet's granule position is smaller than the number of samples in the first packet (= the first sample's timestamp is smaller than 0). Mkvmerge will now shift all timestamps up to 0 in such a case instead of inserting 'discard padding' elements all over the place. Mkvmerge will no longer insert 'discard padding' elements if the difference between a) the calculated number of samples in the packet according to the granule position and b) the actual number of samples as calculated from the bitstream is one sample or less and if the packet isn't the last one in the stream.
This circumvents certain rounding errors. The timestamp of the first packet after a gap in the middle of the stream is now calculated based on the Ogg page the packet belongs to, and not based on the timestamps before the gap. Fixes: Mkvmerge: complete rewrite of the progress handling. It's now based upon the total size of all source files and the current position within them instead of the number of frames/blocks to be processed.
This simplifies calculation when appending files and fixes rare cases of when progress report was obvious wrong (e.g. Stuck at 0% right until the end).

MKVToolNix GUI: header editor: non-mandatory elements couldn't be removed anymore due to a regression while fixing #2320. They can now be removed again.

MKVToolNix is a small collection of tools (mkvmerge, mkvinfo, mkvextract, mkvpropedit and mmg) 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 (AAC, FLAC, MP2, MP3, (E)AC3, DTS/DTS-HD, Vorbis, RealAudio) and also most subtitle formats (SRT, PGS/SUP, VobSub, ASS, SSA etc.). Requirements: OS X 10.9+ 64-bit Intel.
