How to Install MKVToolNix 18.0.0 on Ubuntu 17.10

    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 18.0.0 Changelog:
New features and enhancements
  • build system: when building with clang v3.8.0 or newer, configure will no longer restrict optimization flags to -O1 and use -O3 again (older versions of clang suffered from excessive memory usage with higher optimization levels).
  • build system: when building with mingw 7.2.0 or newer, configure will no longer restrict optimization flags to -O2 and use -O3 again (older versions of mingw suffered from bugs such as segmentation faults with higher optimization levels).
  • build system: stack protection is enabled when building with clang 3.5.0 or newer on all platforms.
  • mkvmerge: AVC & HEVC ES parsers: performance improvements by copying much less memory around.
  • mkvmerge: tags: reintroduced a workaround for non-compliant files with tags that do not contain the mandatory SimpleTag element. This workaround was removed during code refactoring in release v15.0.0.
  • GUI: multiplexer: the "AAC is SBR/HE-AAC/AAC+" checkbox in the "audio properties" section will be disabled if the functionality is not implemented for the selected track’s codec & container.
  • GUI: multiplexer: the "reduce to core" checkbox in the "audio properties" section will be disabled if the functionality is not implemented for the selected track’s codec.
Bug fixes
  • mkvmerge: AAC ADTS parser: fixed interpretation of the channel_configuration header element for ADTS files that do not contain a program configuration element: value 7 means 7.1 channels.
  • mkvmerge: Matroska identification: the date_local and date_utc attributes will only be output if the identified Matroska file actually contains the "date" header field.
  • mkvmerge: WebVTT: mkvmerge did not recognize timestamp lines if the hours components were absent.
  • mkvpropedit, GUI’s header editor: the date header field won’t be added automatically anymore whenever the segment info section is edited and the date element is either deleted or not present in the first place.
