Hey,

here's another release of MKVToolNix. Several bugs have been fixed. A
rather important one is an update to the JSON library used which fixes
immense memory consumption when loading stored settings (e.g. a ~500
KB JSON file leading to consumption of more than 2 GB of memory).

Enhancements include support for WebVTT subtitles, much improved
support for teletext subtitles in MPEG transport streams and several
more fields in the JSON/verbose identification formats.

There have been no changes for package maintainers since the previous
release.

Here are the usual links:

…to the source code: http://mkvtoolnix.download/source.html
…to the binaries: http://mkvtoolnix.download/downloads.html

The Windows and Mac OS binaries are available. Most of the Linux
binaries are still being built and will be available in a couple of
hours.

Here's the full ChangeLog since v9.0.1:

----------------------------------------------------------------------
2016-04-23  Moritz Bunkus  <moritz at bunkus.org>

        * Released v9.1.0 "Little Earthquakes".

        * mkvmerge: MPEG TS/teletext enhancement: included the teletext
        page number in the JSON/verbose identification output as track
        property "teletext_page".

        * mkvmerge: MPEG TS bug fix: the "text_subtitles" property of the
        JSON/verbose identification modes was always set to true for all
        subtitle tracks, even for those that aren't text subtitles
        (VobSub, PG).

        * mkvmerge: MPEG TS/teletext enhancement: if a teletext track
        contains multiple teletext pages then mkvmerge will now recognize
        all of those pages as separate tracks to merge instead of only
        merging the first page. See #1662.

2016-04-21  Moritz Bunkus  <moritz at bunkus.org>

        * mkvmerge: MPEG TS/teletext enhancement: mkvmerge will now ignore
        obviously bogus PTS values for teletext tracks and use PTS from
        earlier audio or video packets instead. See #1662.

2016-04-20  Moritz Bunkus  <moritz at bunkus.org>

        * mkvmerge: MPEG TS/teletext bug fix: the language code signaled
        in the MPEG TS PMT is taken into account when selecting the
        character encoding to use during decoding of the teletext
        subtitles, not just the "national character set" stored in the
        teletext page headers. For example, a German teletext page may
        signal "national character set" 0 (English) whereas it's actually
        4 (German). See #1662.

        * mkvmerge: teletext decoding bug fix: fixed dropping of certain
        non-ASCII characters in rare circumstances due to wrong filtering
        of already UTF-8 encoded strings.

        * mkvmerge: MPEG TS reader enhancement: teletext tracks of type 5
        (hearing impaired) are recognized as subtitles, too. Implements
        #1662.

2016-04-16  Moritz Bunkus  <moritz at bunkus.org>

        * MKVToolNix GUI: merge tool enhancement: characters that aren't
        valid in path names are automatically removed from the output file
        name. Implements #1647.

        * MKVToolNix GUI: bug fix (Windows only): the GUI didn't start
        if the USERNAME environment variable contained characters that
        aren't allowed in file names (e.g. : or ?).

2016-04-13  Moritz Bunkus  <moritz at bunkus.org>

        * mkvmerge: AVI reader bug fix: fixed reading files where the file
        ends in the middle of an audio chunk. Fixes #1657.

2016-04-11  Moritz Bunkus  <moritz at bunkus.org>

        * mkvextract: new feature: added support for extracting WebVTT
        subtitles. Implements the extraction part of #1592.

        * mkvmerge: new feature: added support for reading WebVTT
        subtitles from WebVTT and Matroska files. Implements the merge
        part of #1592.

        * mkvmerge: enhancement: when reading Matroska files not created
        by mkvmerge that contain chapters the existing edition UIDs and
        chapter UIDs are removed and random ones created. This is
        necessary as not only HandBrake but other tools assign sequential
        numbers starting at 1 for each file. Therefore there are two
        chapter entries with the UID 1, two with the UID 2 etc. and those
        should, strictly speaking, be treated as if they were a single
        chapter whereas the user expects those entries to stay separate
        entries.

2016-04-09  Moritz Bunkus  <moritz at bunkus.org>

        * MKVToolNix GUI: new feature: added an option in the preferences
        ("Merge" → "Output") for controlling whether or not the GUI clears
        the "output file name" input upon removal of the last file.

        * MKVToolNix GUI: new feature: added an option in the preferences
        ("Merge" → "Default values") for controlling whether or not the
        GUI clears the "file title" input upon removal of the last file.

        * mkvmerge: bug fix: mkvmerge will no longer abort reading a
        Matroska file with a structural error right before the first
        cluster. Fixes #1654.

2016-04-03  Moritz Bunkus  <moritz at bunkus.org>

        * mkvmerge: enhancement: added the muxing date in both local time
        zone and UTC to verbose/JSON identification outputs (keys
        "date_local" and "date_utc", formatted after ISO 8601) when
        identifying Matroska files.

2016-04-02  Moritz Bunkus  <moritz at bunkus.org>

        * mkvmerge: enhancement: added the minimum timestamp for each
        track in verbose/JSON identification outputs (key
        "minimum_timestamp") when identifying Matroska files. At most the
        first ten seconds are probed; if no block is found for a track
        within that range then the key is not output for the track.

        Also added "muxing_application" and "writing_application" to the
        "container" section of the output. Currently those are only set
        for Matroska files.

2016-03-31  Moritz Bunkus  <moritz at bunkus.org>

        * MKVToolNix GUI: merge tool change: attachments from source files
        have been moved from the "Tracks, chapters, tags and attachments"
        list on the "sources" tab to a new list on the "attachments"
        tab. That way all existing attachments and all the ones to newly
        add will be shown in a single tab. This makes it easier to decide
        which attachments will have to be added and which can be removed.

        * MKVToolNix: merge tool bug fix: when adding playlists the GUI
        won't ask the user whether or not to scan if there's only a single
        playlist in that directory.

2016-03-29  Moritz Bunkus  <moritz at bunkus.org>

        * mkvmerge: bug fix: AVC/h.264: fixed handling of interlaced
        frames with bottom field first.

        * MKVToolNix GUI: bug fix: fixed huge memory consumption
        (e.g. allocation of 2 GB for a JSON file of 650 KB) in the JSON
        library by updating said JSON library. Fixes #1631.

Have fun :)
