The free and open-source MKVToolNix MKV (Matroska) manipulation tool has reached the 9.6.0 release. Here’s how to install or upgrade it in Ubuntu 16.04, Ubuntu 14.04, and/or Ubuntu 16.10.
MKVToolNix 9.6.0 fixes one major bug in mkvmerge (an endless loop) when appending files. It mostly occurred when muxing MPLS playlists. Several other minor bug fixes and usability enhancements were implemented.
- mkvmerge and mkvextract now support HDMV TextST subtitles.
- MKVToolNix GUI has option to only show the list of often used languages/country codes/character sets.
- mkvextract has been updated to add a “langidx” line to the .idx file upon extraction
- multiplexer enhancement: added a column “source file’s directory” to the track list
- multiplexer enhancement: added an option for selecting all tracks of the currently selected source files in the source file context menu
