MKVToolNix GUI: bug fix: the file/track columns aren't resized to fit their content when expanding/collapsing tree nodes anymore. Such expansion also happened when moving entries with the "move up/down" buttons. Fixes #1492
mkvmerge: bug fix: fixed the values of the "previous/next segment UID" elements when splitting by parts with segment linking enabled. Fixes #1497
mkvmerge: bug fix: mkvmerge no longer creates a "next segment UID" field in the last file when splitting and segment linking is active
mkvpropedit, MKVToolNix GUI header editor: enhancement: added the "codec delay" track header field as an editable property.
mkvmerge: bug fix: fixed an endless loop when updating track headers caused by the fix for "Re-rendering track headers: data_size != 0 not implemented yet". Fixes #1485.

Whats new:>>

mkvpropedit, GUI's chapter & header editors bug fix: in certain situations the modified file would not contain a seek head before the first cluster anymore resulting in most players not finding elements such as attachments or the index located at the end of the file anymore. Fixes #1513.
mkvmerge: bug fix: the change to do a deeper file analysis if no seek head was found was causing huge increases in file type detection time as popular tools like x264 don't write seek heads. The way elements at the end are searched has been changed to only scan the last 5 MB of the file instead of iterating over every level 1 element from the beginning of the file.

       * Released v8.7.0.

2015-12-30  Moritz Bunkus  <moritz@bunkus.org>

        * mkvmerge: bug fix: fixed the handling of a PES size of 0 ( =
        unknown). Tracks whose PES packets had such a size were sometimes
        not detected at all, and even if they were their content was
        incomplete. Fixes #1553.

        * mkvmerge: bug fix: made the MPEG 1/2 video elementary stream
        file type recognition more resilient and more flexible dropping
        the requirement for a file to start with an MPEG start code (0x00
        00 01). Fixes #1462.

        * mkvpropedit: bug fix: when changing the track language it is now
        verified to be a valid ISO 639-2 language code before writing it
        to the file. Fixes #1550.

        * mkvmerge: enhancement: the MP4 reader will keep the display
        dimensions from the track header atom ("tkhd") and use them as the
        display width & height. See also #1547.

2015-12-29  Moritz Bunkus  <moritz@bunkus.org>

        * MKVToolNix GUI: merge tool enhancement: the "add source files"
        button now has optional popup menu containing actions for
        adding/appending files and adding files as additional parts for
        easier discovery of those actions. This popup is only shown if the
        user clicks on the arrow shown on the right of the button.

        * mkvmerge: new feature: TrueHD tracks that contain Dolby Atmos
        will be identified as "TrueHD Atmos". Implements #1519.

        * mkvmerge: bug fix: the Matroska reader now uses TrueHD-specific
        code when reading Matroska files. This can fix things like wrong
        frame type flags.

2015-12-28  Moritz Bunkus  <moritz@bunkus.org>

        * mkvmerge: bug fix: MP4 edit lists of certain types (two entries,
        first entry's media_time is -1, second entry's segment_duration is
        != 0) weren't handled properly resulting in key frame flags being
        assigned to the wrong frames. Fixes #1547.

        * mkvmerge: bug fix: the h.265/HEVC code was writing SEI NALUs
        twice. This had already been mentioned in #1076 but never
        fixed. Patch by Vladimír Pilný.

        * mkvmerge: bug fix: the h.265/HEVC code wasn't converting slice
        NALUs to RBSP form before parsing it resulting in wrongly
        timestamped frames under certain conditions. This is a similar fix
        to the issues reported in #918 and #1548.

        * mkvmerge: bug fix: the h.264/AVC code wasn't converting slice
        NALUs to RBSP form before parsing it resulting in wrongly
        timestamped frames under certain conditions. Fixes #918 and #1548.

        * mkvmerge: bug fix: the MP4 reader can now understand the 'random
        access point' sample grouping information for marking open GOP
        random access points as key frames. Fixes #1543.

2015-12-27  Moritz Bunkus  <moritz@bunkus.org>

        * mkvmerge: bug fix: fixed the decisions whether or not to write
        the last frame of a track as a BlockGroup or a SimpleBlock and
        whether or not to write a block duration for that frame. Fixes
        #1545.

        * MKVToolNix GUI: new merge tool feature: added menu options in
        the "Merge" menu for copying either the first source file's name
        or the current output file's name into the "file title" control.

2015-12-22  Moritz Bunkus  <moritz@bunkus.org>

        * mkvpropedit: new feature: added an option for calculating
        statistics for all tracks and adding new/updating existing
        statistics tags in a file. Second half of the implementation of
        #1507.

2015-12-19  Moritz Bunkus  <moritz@bunkus.org>

        * mkvmerge: bug fix: the progress calculation was sometimes
        outputting negative numbers when appending Matroska files whose
        timestamps don't start at 0 (e.g. if they were created by
        splitting with linking enabled). In the the GUI this resulted in
        lines like "#GUI#progress -2%" in the job's output.

        * mkvpropedit: new feature: added an option for removing all
        existing track statistics tags from a file. Part of the
        implementation of #1507.

        * mkvmerge: bug fix: AAC with low sampling frequencies was
        sometimes mis-detected with the wrong profile preventing appending
        it to other AAC tracks. Fixes #1540.

2015-12-17  Moritz Bunkus  <moritz@bunkus.org>

        * mkvmerge: bug fix: chapters were output as both "chapters" and
        "track_tags" in JSON identification mode. Fixes #1538.

        * mkvmerge: enhancement: added the container's internal track ID
        as the "number" attribute in verbose & JSON identification modes
        for several container types (QuickTime/MP4: the track ID from the
        'tkhd' atom; MPEG program stream: the sub-stream ID in the upper
        32 bits and the stream ID in the lower 32 bits; MPEG transport
        stream: the program ID; Ogg/OGM: the stream's serial number field;
        RealMedia: the track ID). Implements #1541.

2015-12-16  Moritz Bunkus  <moritz@bunkus.org>

        * MKVToolNix GUI: bug fix: the "split mode" drop-down box got
        reset to "do not split" each time the preferences dialog was
        closed with the "OK" button. Fixes #1539.

        * mkvmerge: enhancement: if JSON identification mode is active
        then warnings and errors will be output as JSON as well. They're
        output as arrays of strings as the keys "warnings" and "errors" of
        the main JSON object. Implements #1537.

        * all: reversion of a change: several ISO 639-2 codes of languages
        that are very old and not spoken anymore have been re-added
        (e.g. "English, Middle (1100-1500)") due to feedback from users
        who did have a use for such codes.

        * all: reversion of a change: all of the tools will write a byte-order
        mark (BOM) to text files encoded any of the UTF-* schemes
        again. This reverts the change in release 8.6.0 due to user
        feedback preferring the old way.

2015-12-12  Moritz Bunkus  <moritz@bunkus.org>

        * mkvpropedit: enhancement: when using --add-attachment,
        --replace-attachment or --update-attachment the UID can be changed
        with --attachment-uid. See #1532.

        * mkvpropedit: new feature: added an option "--update-attachment"
        for updating the properties of existing attachments without
        replacing their content. Implements #1532.

2015-12-11  Moritz Bunkus  <moritz@bunkus.org>

        * MKVToolNix GUI: new feature: added options for running arbitrary
        programs after a job has finished or after the queue has
        finished. Implements #1406.

2015-12-09  Moritz Bunkus  <moritz@bunkus.org>

        * MKVToolNix GUI: merge tool enhancement: if files are dragged &
        dropped from an external application with the right mouse button
        being pressed then the GUI will always ask the user what to do
        with the files even if the user has configured the GUI not to
        ask. Implements #1508.

        * MKVToolNix GUI: enhancement: when starting the GUI with a saved
        settings file then the GUI won't contain an empty tab in the merge
        tool anymore. Fixes #1504.

2015-12-08  Moritz Bunkus  <moritz@bunkus.org>

        * mkvmerge: bug fix: fixed the key frame detection for VP9 video
        tracks.

        * MKVToolNix GUI: bug fix: relative file names given on the
        command line were interpreted as being relative to the user's home
        directory. Fixes #1534.

2015-12-01  Moritz Bunkus  <m.bunkus@linet-services.de>

        * MKVToolNix GUI: the preferences dialog has been reworked heavily
        in order to provide a better overview and to be less overwhelming.

       * Released v8.8.0.

2016-01-09  Moritz Bunkus  <moritz@bunkus.org>

        * MKVToolNix GUI: "run program after XYZ" enhancement: added a
        button for executing the program right now as a test run. See
        #1570.

        * MKVToolNix GUI: "run program after XYZ" enhancement: an error
        message is shown if the program couldn't be executed. See #1570.

        * MKVToolNix GUI: "run program after XYZ" enhancement: any leading
        spaces in the executable path are removed in order to make copying &
        pasting less error-prone.

        * MKVToolNix GUI: "run program after XYZ" bug fix: the paths used
        in the variables and the executable are converted to the platforms
        native path separators. This fixes compatibility with Windows
        applications that don't support the use of forward slashes in path
        names like e.g. VLC. See #1570.

2016-01-08  Moritz Bunkus  <moritz@bunkus.org>

        * mkvpropedit: enhancement: mkvpropedit will accept terminology
        variants of ISO 639-2 language codes and convert them to the
        bibliographic variants automatically. Implements #1565.

2016-01-06  Moritz Bunkus  <moritz@bunkus.org>

        * MKVToolNix GUI: enhancement: the GUI's default font's size is
        now scaled with the screen's DPI and is at least 9 points high (up
        from . Additionally on Windows "Segoe UI", which is Windows'
        default user interface font, is used instead of the default
        provided by Qt, "MS Shell Dlg 2".

        * MKVToolNix GUI: enhancement: the user can select the font family
        and size for the GUI in the preferences.

2016-01-04  Moritz Bunkus  <moritz@bunkus.org>

        * mkvmerge: bug fix: fixed TrueHD detection both as raw streams as
        well as inside other contains if the stream does not start with a
        TrueHD sync frame.

2016-01-03  Moritz Bunkus  <moritz@bunkus.org>

        * MKVToolNix GUI: new merge tool feature: added a layout for the
        track properties where they're on the right of the files/tracks
        lists in two fixed columns. Implements #1526.

2016-01-02  Moritz Bunkus  <moritz@bunkus.org>

        * mkvmerge: bug fix: fixed a mis-detection of an MPEG-2 video
        elementary stream as a TrueHD file which then caused a
        segmentation fault. Fixes #1559.

        * mkvmerge: bug fix: Matroska attachments with the same name, size
        and MIME type were not output during file identification.

        * MKVToolNix GUI: merge tool enhancement: added a column to the
        "attachments" tab containing the file size.

        * MKVToolNix GUI: enhancement: pressing the insert key when the
        focus is on the merge tool's source files or attachments list, on
        the chapter editor's chapter list or on the header editor's list
        will invoke the corresponding action for adding elements to that
        list.

2016-01-01  Moritz Bunkus  <moritz@bunkus.org>

        * MKVToolNix GUI: merge tool bug fix: when using one of the
        "select all tracks (of type…)" actions the "properties" column
        didn't show the selection.

        * MKVToolNix GUI: new feature: implemented adding, changing and
        removing attachments in existing Matroska files as part of the
        header editor. Implements #1533.

Changelog

* Released v8.9.0.

        * MKVToolNix GUI: the default font size adjustment has been
        deactivated for the time being as it causes problems on high DPI
        displays. See #1602.

        * MKVToolNix GUI: bug fix: ampersands (&) in file names were shown
        as keyboard shortcuts in tab titles in various tools (merge tool,
        chapter and header editors, job output tool). Fixes #1603.

2016-02-20  Moritz Bunkus  <moritz@bunkus.org>

        * MKVToolNix GUI: header editor enhancement: when the user drags &
        drops files on an open header editor tab the GUI will ask the user
        what to do with them: either open the files as new header editor
        tabs or add the files as new attachments to the current tab. The
        action can also be set as the default. Implements #1585.

        * MKVToolNix GUI: chapter & header editor enhancement: Matroska
        files are initially opened in read-only mode and only later
        re-opened in read/write mode in order to enable reading from
        write-protected files. Part of the implementation of #1594.

        * MKVToolNix GUI: chapter & header enhancement: the error messages
        shown when a Matroska file could not be parsed have been improved
        to include the most likely reasons. Part of the implementation of
        #1594.

        * MKVToolNix GUI: chapter editor enhancement: added a menu entry
        for removing chapters from an existing Matroska file. Inspired by
        #1593.

        * MKVToolNix GUI: chapter editor enhancement: it is now possible
        to save chapters to Matroska files after having removed all
        entries (editions and chapter atoms). This effectively removes the
        chapters from the file. Implements #1593.

2016-02-18  Moritz Bunkus  <moritz@bunkus.org>

        * MKVToolNix GUI: job queue enhancement: added keyboard shortcuts
        for removing all completed jobs and for removing successfully
        completed jobs. Implements #1599.

        * MKVToolNix GUI: merge tool enhancement: added icons to the
        context menu actions in the "attachments" sub-tab. Implements
        #1596.

        * MKVToolNix GUI: merge tool enhancement: made the context menu
        entries in the "attachments" sub-tab clearer. Implements #1597.

2016-02-10  Moritz Bunkus  <moritz@bunkus.org>

        * mkvmerge: bug fix: fixed the handling of AVIs with a negative
        video height (which signals that the rows are arranged
        top-to-bottom).

2016-01-31  Moritz Bunkus  <moritz@bunkus.org>

        * MKVToolNix GUI: job queue bug fix: fixed an invalid memory
        access in the "edit in corresponding tool and remove from queue"
        functionality.

        * MKVToolNix GUI: re-write, merge tool bug fix: the file
        identification is now based on mkvmerge's JSON output instead of
        its verbose output. This also fixes the merge tool not showing
        names of attachments inside Matroska files properly if those names
        contain spaces (#1583).

        * MKVToolNix GUI: merge tool bug fix: the "mux this" combo box
        was disabled if a single attachment was selected.

        * mkvmerge: bug fix: removed spurious output generated during file
        identification in the HEVC detection code (e.g. "Error No Error").

        * mkvmerge: bug fix: fixed the output of the "playlist_file" and
        "other_file" properties of the "container" entity in the JSON
        identification format from a single string to an array of
        strings. The format version has been bumped to 3 due to this
        change.

2016-01-30  Moritz Bunkus  <moritz@bunkus.org>

        * docs: added a Polish translation of the man pages by Daniel Kluz
        (see AUTHORS).

        * MKVToolNix GUI: "run program after XYZ" enhancement:
        configurations can now be deactivated without having to change
        them. Implements #1581.

2016-01-24  Moritz Bunkus  <moritz@bunkus.org>

        * mkvmerge: bug fix: fixed parsing of AAC in MP4 with a program
        config element with an empty comment field at the end of the GA
        specific config. Fixes #1578.

2016-01-19  Moritz Bunkus  <moritz@bunkus.org>

        * mkvmerge: enhancement: when reading Matroska files created by
        HandBrake that contain chapters the existing edition UIDs and
        chapter UIDs are removed and random ones created. This is
        necessary as HandBrake assigns 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. Implements an
        improvement for issues such as #1561.

        * MKVToolNix GUI: merge tool bug fix: the GUI no longer requires
        at least one source file to be present before muxing can start in
        order to allow creation of track-less files. Fixes #1576.

2016-01-16  Moritz Bunkus  <moritz@bunkus.org>

        * MKVToolNix GUI: enhancement: the "escape for Windows' cmd.exe"
        mechanism will only escape arguments that actually need escaping
        in order to produce easier to read command lines.

2016-01-15  Moritz Bunkus  <moritz@bunkus.org>

        * mkvmerge: QuickTime/MP4 reader: fix a division by zero in the
        index generation for certain old audio codecs that have certain
        header fields (bytes_per_frame, samples_per_packet) set to 0.

2016-01-13  Moritz Bunkus  <moritz@bunkus.org>

        * mkvinfo: bug fix: global elements (EBML void and CRC-32
        elements) are now handled correctly if they're located inside the
        segment info or the chapter translate parents.

Changelog

Installer: fixed support for silent installation and uninstallation.

mkvmerge: bug fix: fixed two more issues in the conversion of teletext subtitles to SRT subtitles:

Packets belonging to pages that don't contain subtitles were used as valid end points for subtitles causing entries to become very short (e.g. 40ms).
Sometimes the timestamps of wrong packets were used as entry's start and end points causing start timestamps and durations that were slightly off.
mkvmerge: MP4/QuickTime reader: audio tracks with the FourCC lpcm' are muxed as A_PCM/INT/LIT instead of A_QUICKTIME mkvmerge: bug fix: MP4/QuickTime reader: audio tracks can contain two instances of certain header fields (channel count bits/sample & channel, sample rate) in the STSD atom: one instance in the version 0 header and one in the version 2 header parts. So
far mkvmerge has used those from the version 0 header only and ignored the ones from the version 2 header. This has been changed to match the behavior of other players and MP4 readers like ffmpeg. If the STSD atom contains a version 2 structure then the fields from it will be used. Otherwise the fields from the version 0 part will be used
all: new feature: added a new translation of both the programs and the man pages to Korean by Potato (see AUTHORS)
MKVToolNix GUI: chapter editor enhancement: added a button next to the 'segment UID' controls that enable the user to select a Matroska file. The GUI reads that file's segment UID and enters its value into the input field
build system: added an option to configure without-qt-pkg-config«. Normally configure uses pkg-config for detecting Qt and setting QT_CFLAGS and QT_LIBS. With this option configure won't use pkg-config and rely on the user having set both variables before running configure. This enables using Qt on systems where no pkg-config files are generated (e.g. Qt 5.6.0 on MacOS with frameworks enabled)
mkvinfo: change: on Windows and Mac OS mkvinfo will now launch the GUI by default unless the option »--no-gui« (or »-G«) has been given. This is due to the fact that on both OS users often use portable versions respectively disk images and launch the executable directly and not via start menu entries. In those situations adding command line options for launching the GUI is unnecessarily difficult.

mkvmerge: bug fix: fixed two issues in the conversion of teletext subtitles to SRT subtitles:

Consecutive teletext packets with the same content are now merged into a single entry instead of resulting in multiple entries.
The calculation of a packet's duration was wrong in certain situations.
MKVToolNix GUI: merge tool (playlist selection dialog) enhancement: the playlist items are sorted by their position within the playlist by default.
MKVToolNix GUI: merge tool (playlist selection dialog) enhancement: double-clicking on a playlist will select and add that playlist.
mkvmerge: enhancement: added the number of bits per sample to the verbose/JSON identification output for FLAC files.
mkvextract: bug fix: fixed the duplication of VPS, SPS, PPS and SEI NALUs when extracting h.265/HEVC tracks. See #1076 and #1621.
mkvmerge: bug fix: reverted the patch that made the h.265/HEVC not store SEI NALUs with the frames during
muxing. It was supposed to prevent having the SEI NALUs present twice when extracting HEVC due to some SEI information also being stored in the codec private data, but it dropped a lot of other SEI NALUs irrevocably. Fixes #1621.
mkvmerge: bug fix: the --sub-charset option is now ignored for text subtitle files that start with a byte-order mark (BOM) bringing the behavior in line with the documentation. Fixes #1620.
mkvextract: new feature: implemented the extraction of Big Endian PCM (codec ID A_PCM/INT/BIG) to WAV files. The content will be byte-swapped into Little Endian PCM in the process.
mkvmerge: enhancement: Big Endian PCM tracks will now be byte-swapped into Little Endian PCM, and the codec ID A_PCM/INT/LIT will be used. This was done due to a lot of players not supporting Big Endian PCM inside Matroska.
mkvmerge, MKVToolNix GUI: new feature: added switches (generate-chapters and generate-chapter-name-template) and their corresponding UI items for generating chapters while muxing. Two modes are currently supported: when-appending which creates one chapter at the beginning and an additional one each time a file is appended and interval which generates chapters in fixed intervals Implements mkvmerge's and the GUI's part of #1586
MKVToolNix GUI: job queue enhancement: completed jobs will now be removed from the queue automatically on exit if the job has been added more than 14 days ago in order not to let the queue grow arbitrarily large. This feature can be turned off and the number of days can be adjusted in the preferences.
mkvpropedit, MKVToolNix GUI's header editor: bug fix: fixed the handling of files where the last level 1 element has an unknown size. The programs will now either fix this element to have a known size or abort the process with an appropriate error message but without modifying the file. Fixes #1601.
mkvextract: enhancement: when extracting chapters in the simple format the user can use the new option 'simple-language' for selecting the chapter names that are output. Normally the first chapter name found in each atom is used. With this option mkvextract looks for a chapter name whose language matches the specified one. Implements the feature enhancement part of #1610.
mkvextract: several issues regarding the extraction of chapters in the simple format have been fixed: if multiple names with different languages were present then an entry had been written for each name; the total number of entries written was wrong; the wrong entries were written. The new code only writes the first name found from the top-most chapter atoms of all editions. Chapters flagged as hidden or as not enabled are not extracted at all. Fixes the bug part of #1610.
MKVToolNix GUI: new chapter editor feature: added an option to multiply all chapter timecodes by a factor to the "additional modifications" dialog. Implements #1609.

        * 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@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@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@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@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@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@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@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@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@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.

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". Implements #1698
MKVToolNix GUI: bug fix on Windows: removing the drive letter does not cause the colon to be removed automatically anymore. Fixes #1692
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. Fixes #1695
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. Fixes #1693
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"
mkvmerge: bug fix: fixed detection of (E-)AC-3 in MPEG TS files with unusual stream types (e.g. 0x87) but with (E-)AC-3 PMT descriptors. Fixes #1684
mkvmerge, mkvextract: bug fix: fixed handling of Big Endian PCM with a bit depth other than 16, 32 or 64 bits/sample. Other formats were using the Little Endian codec ID, but their content was actually not byte-swapped to match it. Now those other bit depths are byte-swapped to Little Endian, too. Fixes #1683.
mkvinfo: the change to start the GUI by default on Windows and Mac OS has been reverted. Instead a separate executable mkvinfo-gui) will be included for those platforms which starts the GUI by default. The newly introduced option "--no-gui" will remain valid but won't have any effect when used with mkvinfo.
mkvinfo GUI: enhancement: the window title now includes the file name. Implements #1679.
mkvmerge: enhancement: the "bit depth" track header field will be set for DTS tracks from the first DTS core header. Implements 1680.
mkvmerge: bug fix: the time zone portion of the "date_local" member of the JSON and verbose identification formats contained the time zone's name instead of its offset on Windows due to the Visual C++ runtime's std::strftime not being C++11 compliant.
Additionally this resulted in errors about invalid UTF-8 strings for locales where the time zone's name contained non-ASCII characters.

Changelog

* Released v9.3.0 "Second Sight".

        * build system: libEBML v1.3.4 and libMatroska v1.4.5 are now
        required due to several new elements having been specified for
        Matroska, and mkvmerge uses those elements.

2016-07-10  Moritz Bunkus  <moritz@bunkus.org>

        * mkvmerge, MKVToolNix GUI: new chapter generation feature: two
        new placeholders have been introduced when generating chapters for
        appended files, <FILE_NAME> and <FILE_NAME_WITH_EXT>. The former
        will be replaced by the appended file's name without its
        extension; the latter with its extension. Implements #1737.

        * MKVToolNix GUI: merge tool enhancement: when opening a saved
        configuration (via the menu as well as via drag & drop) the
        current tab will be replaced if it is empty ( = in the same state
        it is in right after creating new mux settings). Implements #1738.

        * mkvmerge, MKVToolNix GUI: added an option for specifying how
        much of a MPEG PS or TS file is probed for tracks
        (--probe-range-percentage).  Implements #1734.

2016-07-09  Moritz Bunkus  <moritz@bunkus.org>

        * mkvmerge: MPEG TS: considerable parts of the module have been
        rewritten. Due to its convoluted structure didn't buffer PES
        packets properly before trying to parse the PES header leading to
        invalid memory accesses in certain cases.

2016-07-03  Moritz Bunkus  <moritz@bunkus.org>

        * mkvmerge: bug fix: fixed overly long file type detection in some
        cases when text subtitle type probing read a lot of data due to
        there being no carriage returns near the start of the file.

        * mkvmerge, mkvextract, MKVToolNix GUI: bug fix: several fixes to
        the handling of country codes. The list has been updated to
        reflect the currently valid top level domain country
        codes. Deprecated codes such as "gb" for "Great Britain" are now
        mapped to their updated values ("uk" for "United Kingdom" in this
        case). Fixes #1731.

        * mkvmerge: WavPack4 bug fix: relaxed the stream detection
        criteria to only require the major version to be 4 and not to
        check the minor version. Fixes #1720.

2016-07-02  Chao Chen <tochenchao@gmail.com>

        * mkvmerge, mkvinfo: new feature: added flags to support the
        Colour elements in the video tracks of Matroska containers. Users
        can use those flags to specify the colour space, transfer
        function, chromaticity coordinates etc. These properties are
        useful for correct colour reproduction of high dynamic range /
        wide colour gamut videos.

2016-07-02  Moritz Bunkus  <moritz@bunkus.org>

        * configure: fixed the Qt detection with Qt 5.7.0 which now
        requires the compiler to be in C++11 mode.

        * build system: libEBML v1.3.4 and libMatroska v1.4.5 are now
        required due to the usage of new elements introduced in
        libMatroska v1.4.5. The copies included in the MKVToolNix source
        code have been updated to those releases as well.

2016-06-28  Moritz Bunkus  <moritz@bunkus.org>

        * mkvmerge: MP4 bug fix wrt. DTS handling: mkvmerge will re-derive
        parameters such as number of channels and sampling frequency from
        the DTS bitstream circumventing invalid values in the track
        headers (e.g. a channel count of 0). Fixes #1727/1728.

2016-06-27  Moritz Bunkus  <moritz@bunkus.org>

        * mkvmerge: TrueHD bug fix: fixed detection of 96 kHz sampling
        frequency.

2016-06-24  Moritz Bunkus  <moritz@bunkus.org>

        * mkvinfo's GUI: fix a crash due to wrong usage of referenced
        temporary objects. Fixes #1725.

2016-06-05  Moritz Bunkus  <moritz@bunkus.org>

        * MKVToolNix GUI: merge tool enhancement: the default track
        languages to set can now also be set whenever the language in the
        source file is 'undefined' ('und'). This is now the default and
        can be changed back to the old behavior (only set if the source
        file doesn't contain a language attribute) in the
        preferences. Implements #1697.

2016-06-04  Moritz Bunkus  <moritz@bunkus.org>

        * MKVToolNix GUI: merge tool enhancement: menus have been added to
        both the "start muxing" and the "add to job queue" buttons. The
        menus let the user override the preferences regarding clearing
        merge settings after starting to mux and after adding a job to the
        queue respectively. Implements #1696.

        * mkvmerge: the warning about not being able to determine whether
        a raw AAC file contains HE-AAC/AAC+/SBR has been
        removed. Implements #1701.

        * MKVToolNix GUI: enhancement: all file names are now displayed
        with their native path separators (e.g. "C:\some\where\output.mkv"
        on Windows). Implements #1298, #1456.

        * MKVToolNix GUI: merge tool bug fix: the GUI now takes into
        account whether splitting is activated when looking for and
        warning due to existing destination files. Fixes #1694.

        * mkvmerge: bug fix: the parser for the --default-duration
        argument was wrongfully handling arguments of the form "123/456i"
        (only this specific syntax and only with "i" as the unit; other
        formats and units were fine). This is part of #1673.

        Additionally the parser doesn't use the "double" data type
        internally anymore fixing loss of precision and failing test cases
        on certain 32bit platforms. This fixes #1705.

mkvpropedit: bug fix: mkvpropedit will no longer say that it's writing the changes if only attachment changes are specified and none of the specified attachments can be found.
MKVToolNix GUI: chapter editor bug fix: overly long chapter names don't cause the GUI's window to become overly wide anymore. Fixes #1760.
mkvmerge: DTS bug fix: if present mkvmerge will use an XLL extension's sample rate information as the sample rate to put into the track headers. Fixes #1762.
mkvmerge: new feature: added support for reading Apple ProRes video from MOV/MP4 files. Patch by Chao Chen (see AUTHORS).
mkvmerge: bug fix: when appending files mkvmerge wasn't starting clusters on video key frame anymore for the first and all following appended files. Fixes #1757.
MKVToolNix GUI: merge tool enhancement: when adding attachments the GUI will check if there are attachments or attached files with the same name as the file to add. If so the GUI will tell the user and ask for confirmation.
mkvmerge: enhancement: mkvmerge now accepts file names in square brackets for appending files, e.g. "mvkmerge -o out.mkv [ in1.avi in2.avi in3.avi ]" instead of "mkvmerge -o out.mkv in1.avi + in2.avi + in3.avi".
mkvmerge: bug fix: VP8 in Ogg: fixed dropping the first frame and the timestamp calculation. Fixes #1754.
mkvmerge: bug fix: mkvmerge does no longer emit a warning if no comment header packet is found when reading tracks from Ogg/OGM files. See #1754.
MKVToolNix GUI: merge tool enhancement: the "select a play list to add" dialog does now contain a column with the number of chapters for each play list found.
MKVToolNix GUI: job queue enhancement: dragging & dropping a valid .mtxcfg file (either a full job file or one containing only merge settings without the job properties) onto the job queue window will import the dropped .mtxcfg job into the job queue. Rest of the implementation of #1714.
MKVToolNix GUI: merge tool enhancement: dragging & dropping a job queue .mtxcfg file onto the merge tool or using one as a command line parameter to the mkvtoolnix-gui executable will import the .mtxcfg job into the job queue. Part of the implementation of #1714.
MKVToolNix GUI: merge tool bug fix: the automatic adjustments to the output file name based on the track types selected for muxing and the mechanism for keeping output file names unique had been broken since release v9.3.0. Fixes #1743.
MKVToolNix GUI: merge tool enhancement: toggling the WebM mode check box will update the output file name's extension automatically.

Changelog

* Released v9.4.2 "So High".

        * mkvmerge: bug fix: AVC & HEVC readers: release v9.4.1 contains a
        change to both readers so that they will refuse to handle files
        where the detected pixel width or height is equal to or less than
        0. This check was wrong in certain cases causing mkvmerge to
        reject a file as an unsupported file type. This has been fixed
        while keeping the constraints on width & height having to be
        positive.

        * Released v9.4.1 "Black Rain".

2016-09-07  Moritz Bunkus  <moritz@bunkus.org>

        * Note: most of the bugs fixed on 2016-09-06 and 2016-09-07 for
        issue #1780 are potentially exploitable. The scenario is arbitrary
        code execution with specially-crafted files. Updating is highly
        recommended.

        * mkvmerge: bug fix: AVC & HEVC readers: the readers will now
        refuse to handle files where the detected pixel width or height is
        equal to or less than 0. Before this fix the muxing process
        aborted with an assertion inside libMatroska. Fixes the last test
        case of #1780.

        * mkvmerge: bug fix: HEVC parser: fixed another invalid memory
        access (beyond the end of allocated space). Fixes two test cases
        of #1780.

2016-09-06  Moritz Bunkus  <moritz@bunkus.org>

        * mkvmerge: bug fix: HEVC parser: fixed another invalid memory
        access (beyond the end of a fixed-size array). Fixes several test
        cases of #1780.

        * mkvmerge: bug fix: MP4 reader: an error message will be printed
        instead of an uncaught exception when an invalid atom chunk size
        is encountered during resync. Fixes a test case of #1780.

        * mkvmerge: bug fix: AAC reader: fixed mkvmerge throwing an
        uncaught exception due to the sample rate being 0. Fixes a test
        case of #1780.

        * mkvmerge: bug fix: MP4 reader: fixed an invalid memory access
        (beyond the end of allocated space). Fixes several test cases of

        * mkvmerge: bug fix: fixed an invalid memory access (use after
        free) during global destruction phase. Fixes several test cases of
        #1780.

2016-09-02  Moritz Bunkus  <moritz@bunkus.org>

Changelog

mkvmerge, mkvextract: VobSub handling bug fix: mkvmerge and mkvextract will now update the duration stored in the SPU bitsream with the duration from the container level if it differs at least 1ms. Fixes #1771.
mkvmerge: h.264 elementary stream handling bug fix: if mkvmerge ever encounters changing SPS or PPS NALUs (ones where their ID has been encountered before with different settings) in the h.264 then it will prepend all following key frames with all currently active SPS and PPS NALUs. This enables playback from arbitrary key frames even if they require other SPS or PPS settings than the ones stored in the AVCC in CodecPrivate. Fixes #1711.
mkvmerge, mkvpropedit, MKVToolNix GUI: added support for the "field order" video track header element.
mkvinfo: added support for the "field order" video track header element.
mkvmerge: MPEG transport stream reader bug fix: fixed the handling of Blu-ray PCM audio with an odd number of channels by removing their alignment bytes.
mkvmerge: MPEG transport stream reader bug fix: fixed mis-detection of certain h.264 files as MPEG transport streams.
mkvmerge: WAV reader bug fix: the track properties (channels, sample rate) for DTS and AC-3 in WAV will now be derived from the decoded bitstream headers instead of the WAV file header as the latter is often incorrect.
mkvmerge: WAV reader bug fix: fixed detection and merging of DTS in WAV that uses the 14-bytes-in-16-bytes packing method.
MKVToolNix GUI: merge tool enhancement: added menu entries that execute the "close", "save settings", "start muxing" or "add to job queue" action for all currently open tabs
MKVToolNix GUI: merge tool enhancement: when dragging & dropping directories the GUI will process all files within those directories recursively instead.
mkvpropedit, MKVToolNix GUI's header editor: added options to modify the "muxing application" and "writing application" elements in the "segment information" container. Implements #1788
mkvmerge: bug fix: The Ogg/OGM reader did not recognize Opus files with comment headers anymore. This was broken by the fix to not require Ogg/OGM files to have comment headers in v9.4.0
