MKVToolNix v12.0.0 released

2017-05-20 — mosu

Today I’ve released v12.0.0 of MKVToolNix. Not too many changes in this one, but at least one rather important bug fix in the HEVC/h.265 code that can result in invalid files. I therefore recommend everyone to update.

Windows users should note that starting with v11.0.0 the GUI requires Microsoft’s “Media Foundation” framework to be installed. This is the case out of the box on the consumer versions of Windows other than the N and KN variants of Windows 10. You’ll have to download and install it separate on N and KN. On server variants you can install the framework via the server administration console. See this FAQ entry for more details.

There have been no additional changes since v11.0.0 that package maintainers should be aware of.

You can download the source code or one of the binaries. The Windows and macOS binaries have been built already and are available for download. The Linux binaries will be available later today.

Here’s the NEWS since the previous release:

New features and enhancements

• MKVToolNix GUI: the key combination Ctrl+Shift+Space will now toggle the selection of the current item in all tree views where multiple selections are allowed. Implements #1983.
• MKVToolNix GUI: chapter editor: added the extension \*.cue (for cue sheet files) to the “open chapter file” dialog.
• mkvmerge: cue sheet parser: if the cue sheet contains a non-empty TITLE entry and if no other segment title has been set yet, then the segment title will be set to the cue sheet’s TITLE value. Implements #1977.
• mkvmerge, MKVToolNix GUI (multiplexer): added an option –no-date that prevents the “date” field from being written to the segment information headers. Implements one half of #1964.
• mkvpropedit, MKVToolNix GUI: header editor: added support for editing the “date” segment information field. Implements the other half of #1964.

Bug fixes

• MKVToolNix GUI: preferences → job actions, type “play audio file”: the GUI will no longer clear the audio file name input if the user aborts the audio file selection dialog.
• MKVToolNix GUI: preferences → job actions, type “play audio file”, on Windows: the default “play audio” action was pointing to the wrong directory. Existing configurations with such a wrong path will be fixed automatically upon starting the GUI. Fixes #1956.
• mkvmerge: HEVC/h.265 parser: fixed the superfluous copying of the bitstream\_restriction\_flag and its dependent flags in the VUI parameters of the sequence parameter sets if the timing information is present, too. This fixes #1924 properly, and it also fixes #1958.
• mkvmerge: MPEG TS reader, AAC parser: the MPEG TS reader will now force the AAC parser to use the multiplex mode that the MPEG TS reader has detected (e.g. LOAS/LATM). This prevents the AAC packetizer from mis-detecting it in its own attempt to identify the mode. Fixes #1957.
• mkvmerge: MPEG TS reader: valid MPEG transport streams that start with an h.264/h.265 start code (e.g. a file created by cutting at an arbitrary position) were not recognized as a supported file type.
• mkvmerge: MPEG TS reader: fixed a potential read access from invalid memory addresses in the code parsing the program map table (PMT).
• mkvmerge: MPEG TS reader: if packets are encountered that belong to a PID not listed in the program map table (PMT), mkvmerge will attempt to determine their type and codec from the content. This supported content types are AAC (ADTS only) and AC-3. Fixes #1980.
• mkvmerge: MP4 reader: fixed finding and parsing the colr atom if there are more than one video extension atoms and the colr atom is not the first one.
• mkvmerge: MP4 reader: the nclx colour type of the colr atom is now recognized, too (as defined by ISO/IEC 14496-12, “ISO base media format”).
• configure: fixed configure aborting if a moc, uic, rcc or qmake binary is found, but the binary’s version is too old. Fixes #1979.

Have fun :)
