How to Install MKVToolNix 9.6.0 on Ubuntu 16.10

   MKVtoolnix is a set of tools to create, alter, split, join and inspect Matroska files(mkv). With these tools one can get information about (mkvinfo) Matroska files, extract tracks/data from (mkvextract) Matroska files and create (mkvmerge) Matroska files from other media files. Matroska is a multimedia file format aiming to become THE new container format for the future. Use MKVCleaver or gMKVExtractGUI to extract/demultiplex mkv video and audio files.

MKVToolNix 9.6.0 changelog

• mkvextract: VobSub bug fix: mkvextract will add a "langidx" line  to the .idx file upon extraction.
• MKVToolNix GUI: multiplexer enhancement: added a column "source file's directory" to the track list.
• MKVToolNix GUI: multiplexer enhancement: added an option for selecting all tracks of the currently selected source files in the source file context menu.
• MKVToolNix GUI: job output tool bug fix: the button for acknowledging warnings & errors wasn't properly disabled when the user used outside methods of acknowledging them (e.g. via the menu or via the job queue).
• mkvmerge: MPLS parser bug fix: fixed reading the "in" & "out" timestamps for "play items". This bug resulted in mkvmerge not  reading the correct range from the referenced M2TS file under certain rare circumstances.
• mkvmerge: bug fix: mkvmerge was entering endless loops under certain conditions when appending files.
• MKVToolNix GUI: new feature: added options in the preferences to only show the list of often used languages/country codes/character sets in their respective selections instead of both the often used and the full list.
• Released v9.5.0 "Quiet Fire".
• mkvmerge, mkvextract: VobSub handling bug fix: mkvmerge and mkvextract will now update the duration stored in the SPU bitsream with the duration from the container level if it differs at least 1ms.
