How to Install MKVToolNix 9.2.0 on Ubuntu 16.04

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 9.2.0 changelog

• MKVToolNix GUI: merge tool enhancement: the action "select all attached files" in the popup menu actions for the attached files  view has been split up into "enable all attached files" and  "disable all attached files"
•  MKVToolNix GUI: bug fix on Windows: removing the drive letter  does not cause the colon to be removed automatically anymore.
• MKVToolNix GUI: merge tool bug fix: it's no longer possible to select "1" as the maximum number of files to split into as mkvmerge doesn't accept that value.
  mkvmerge: bug fix: the "interval" chapter generation mode was always creating one chapter too many.
• mkvmerge: bug fix: if a certain number of chapters had been generated with --generate-chapters then mkvmerge wasn't replacing the void placerholder with the actual chapters.
• MKVToolNix GUI: merge tool bug fix: the track column "default track in output" wasn't taking into account if the track had its "default track" flag set to "no" in the source file. This would result in the column showing "yes" in certain situations even though mkvmerge would assign "no".
• See changelog for more details
