How to Install MKVToolNix 19.0.0 on Ubuntu 17.04, 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.

Important notes

• The MKVToolNix project now contains a [Code of Conduct](https://mkvtoolnix.download/doc/CODE_OF_CONDUCT.md).
• The MKVToolNix project's source code repository, bug tracker and wiki have been moved to [GitLab](https://gitlab.com/mbunkus/mkvtoolnix/).

New features and enhancements

• mkvmerge: splitting by duration, by timestamps or by timestamp-based parts: mkvmerge will now consider the first key frame within 1ms of the requested value to be eligible for splitting.
• MKVToolNix GUI: the GUI will now save and restore the widths of columns in tree and list views.
• MKVToolNix GUI: header editor: when closing or reloading a modified file, the GUI will now focus the first element that's been modified before asking the user for confirmation regarding discarding unsaved changes.

Bug fixes

• mkvmerge: fixed reading text files encoded in UTF-16 order UTF-32 that have different forms of line endings (new lines, carriage returns or a mix of both).
• mkvmerge: MP4 reader: fixed mkvmerge's interpretation of edit list entries with `segment_duration == 0` when there's more than one edit list entry. In that case mkvmerge was reading the whole content more than once.
• mkvmerge, GUI's multiplexer: MIME types: added the `font` top-level media types from RFC 8081. This means that the following new MIME types for fonts can be used: `font/ttf`, `font/otf`, `font/woff` and `font/woff2`.
• mkvmerge: MPEG transport stream reader: fixed slow speed on Windows due to lack of buffering.
• mkvextract: fixed slow track extraction speed on Windows due to lack of buffering.
• MKVToolNix GUI: multiplexer: changing the "subtitle/chapter character set" drop-down was ignored when the selected track was a chapter track.
• MKVToolNix GUI: multiplexer: once a "subtitle/chapter character set" was set for a track it couldn't be changed back to the empty entry (= auto-detection) anymore.
• MKVToolNix GUI: header editor: fixed re-translating several displayed strings when the GUI language is changed if the language the GUI was started with was not English.
• MKVToolNix GUI: header editor: whenever a file did not contain a "date" element in its segment information section, the GUI would erroneously ask the user to confirm discarding unsaved changes when closing or reloading the tab.
• MKVToolNix GUI: job queue: jobs are now saved when their status changes in addition to when the program exits.
