Download MKVToolNix 5.3.0

MKVToolNix has been updated to version 5.3.0. MKVToolNix is ​​a collection of open source programs that allow viewing, editing, and conversion of Matroska files. For example, unnecessary audio tracks and subtitles can be removed or set as default. They are separate command line tools, but a graphical user interface is included. Versions are available for download for Windows, many Linux distributions, and Mac OS X. This release includes the following changes and improvements:

Changes in version 5.3.0:

• mkvmerge: new feature: mkvmerge will parse and apply the audio encoder delay in MP4 files that contain said information in the format that iTunes writes it. Fix for bug 715.
• mkvmerge: new feature: Implemented support for treating several input files as if they had been concatenated binarily into a single big input file. Snytax is “mkvmerge -o out.mkv ( in1.ts in2.ts in3.ts )”. This feature has already been present since version 5.1.0 but never been mentioned in the ChangeLog. Support for this feature in mmg is still missing.
• mkvmerge: bug fix: Blocks with “BlockAdditions” will no longer be muxed as “SimpleBlock” elements discarding the additions but instead as “BlockGroup” elements. This applies to eg WAVPACK4 tracks with correction files as the correction data is stored in “BlockAdditions”. Fix for bug 713.
• mkvmerge: bug fix: Fixed some more issues with (E)AC3 being misdtected as AVC elementary streams.
• mmg: bug fix: The header editor was sometimes creating two instances of an element if an element was added to the second or one of the later tracks. Fix for bug 711.
• mkvpropedit, mmg: bug fix: Trying to modify a file located in a path mounted with GVFS SFTP will no longer crash the programs. Instead an error message is output if an error occurs. Fix for bug 710.
• mkvmerge: bug fix: Fixed integer underflows in the read caching code resulting in invalid memory access. Happened in broken or incomplete files only. Fix for bug 709.
• mkvmerge: bug fix: Appending AVI, Matroska or MPEG program stream files with DTS audio tracks will not result in a warning that the appended DTS tracks might not be compatible. Fix for bug 705.
• mkvextract: bug fix for the “timecodes_v2” mode: mkvextract will write one more timecode than there are frames in the file. The last timecode written will be the the sum of the last frame’s timecode and duration with the “last frame” being the one with the highest timecode. Fix for bug 691.
• mkvmerge: bug fix: Fixed writing into paths on which a drive is mounted on Windows. Fix for bug 701.
• mkvmerge: enhancement: Identification output for Matroska files: Added the track number header field as “number” to the verbose identification mode.
• mkvmerge: enhancement: Identification output for Matroska files: Added a field “content_encoding_algorithms” that contains a comma-separated list of encoding algorithm IDs used for that track. For example, “content_encoding_algorithms:3” would indicate that header removal compression is used.
• mkvmerge: enhancement: Identification output for Matroska files: Added several fields to mkvmerge’s verbose identification mode for tracks: UID, CodecID, length and content (as a hex dump) of the codec private data.
• mkvmerge: bug fix: Fixed a segmentation fault in the DTS detection code. Fix for bug 698.
• mkvextract: bug fix: The track IDs used in the “timecodes_v2” extraction mode are consistent again with the IDs that mkvmerge’s identification reports and that mkvextract’s “tracks” extraction mode uses. Fix for bugs 689 and 694.
• mkvmerge: enhancement: Added video pixel dimensions to the output of “–identify-verbose” for Matroska files.
