Install MKVToolnix in Ubuntu 14.04

MKVToolnix is a free set of open-source, cross-platform tools to create, alter, split, join and inspect Matroska files (mkv) under Linux, other Unixes and Windows. 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 new multimedia file format aiming to become the new container format for the future.

Some bug fixes, new features and enhancement

  • If a single subtitle track contains two or more entries at the same timecode then the cue duration and cue relative position elements written were wrong
  • fixed wrong progress percentage shown during saving the information to text files
  • Added a global option for disabling writing the tags with statistics for each track
  • When identifying a Matroska file in verbose identification mode track-specific tags will be output as well
  • mkvmerge will write track-specific tags with statistics for the average number of bits per second, for the duration, and for the track’s size in bytes and its number of frames/packets)
  • Changed the file type detection order again. The text subtitle formats are now probed after those binary formats that can be detected quickly and unambiguously. This avoids some mis-detection if e.g. Matroska files as ASS text subtitles if they do contain such a track
  • The chapter editor will only use fast-mode parsing when loading chapters from Matroska files
  • Fixed invalid memory access in the cleanup procedures which only occurred if the output was redirected with the redirect-output command line parameter
  • Selecting a subtitle track correctly sets the character set drop-down box if no character set was set for this track
  • Fixed huge memory usage when probing files (it was reading the whole file into memory for that)
  • Reading fonts embedded in SSA/ASS files was sometimes truncating the attachments created from them
  • Fixed display of very large IDs during attachment extraction
  • Improved file type detection speed for text subtitle formats
