mkvtoolnix: updated to 25.0.0

Version 25.0.0 "Prog Noir" 2018-07-12

New features and enhancements
* mkvmerge: SRT/ASS/SSA text subtitles: for files for which no encoding has
  been specified, mkvmerge will try UTF-8 first before falling back to the
  system's default encoding.
* mkvmerge: SRT/ASS/SSA/WebVTT text subtitles: a warning is now emitted if
  invalid 8-bit characters are encountered outside valid multi-byte UTF-8
  sequences.
* mkvmerge: Matroska & MPEG transport stream readers: the encoding of text
  subtitles read from Matroska files can now be changed with the
  `--sub-charset` parameter.
* Linux: starting with release 25 an AppImage will be provided which should
  run on any Linux distribution released around the time of CentOS 7/Ubuntu
  14.04 or later.
* macOS: translations: updated the `build.sh` script to build `libiconv` and a
  complete `gettext`. Together with an additional fix to how translation files
  are located, MKVToolNix can now use all interface languages on macOS,
  too.

Bug fixes
* mkvmerge: AVC/h.264: fixed file identification failing for certain
  elementary streams due to internal buffers not being cleared properly.
* mkvmerge: HEVC/h.265: fixed file identification failing for certain
  elementary streams due to internal buffers not being cleared properly.
* mkvmerge: MLP code: fixed various issues preventing MLP from being parsed
  correctly.
* mkvmerge: TrueHD/MLP packetizer; dialog volume normalization removal isn't
  attempted if the track is an MLP track as the operation is only supported
  for TrueHD, not MLP.
* mkvmerge: MPEG TS reader: when reading MPLS mkvmerge will now compare the
  MPLS's start and end timestamps against the transport stream's PTS instead
  of its DTS. Otherwise the first key frame of a video track might be dropped
  if it isn't the first in presentation order.
* mkvmerge: JSON identification: mkvmerge will ensure that all strings passed
  to the JSON output modules are valid UTF-8 encoded strings by replacing
  invalid bytes with placeholder characters. This avoids the JSON library
  throwing an exception and mkvmerge aborting on such data.
* mkvmerge: audio packetizers: mkvmerge will now keep discard padding values
  if they're present for packets read from Matroska files.
* mkvmerge: Ogg Opus reader: packet timestamps aren't calculated by summing up
  the duration of all packets starting with timestamp 0 anymore. Instead the
  algorithm is based on the Ogg page's granule position and which packet
  number is currently timestamped (special handling for the first and last
  packets in the stream).

  * This fixes the first timestamp if the first Ogg packet's granule position
    is larger than the number of samples in the first packet (= if the first
    sample's timestamp is bigger than 0). mkvmerge will keep those offsets now
    and inserts "discard padding" only where it's actually needed.
  * It also improves handling of invalid files where the first Ogg packet's
    granule position is smaller than the number of samples in the first packet
    (= the first sample's timestamp is smaller than 0). mkvmerge will now
    shift all timestamps up to 0 in such a case instead of inserting "discard
    padding" elements all over the place.
  * mkvmerge will no longer insert "discard padding" elements if the
    difference between a) the calculated number of samples in the packet
    according to the granule position and b) the actual number of samples as
    calculated from the bitstream is one sample or less and if the packet
    isn't the last one in the stream. This circumvents certain rounding
    errors.
  * The timestamp of the first packet after a gap in the middle of the stream
    is now calculated based on the Ogg page the packet belongs to, and not
    based on the timestamps before the gap.

* mkvmerge: complete rewrite of the progress handling. It's now based upon the
  total size of all source files and the current position within them instead
  of the number of frames/blocks to be processed. This simplifies calculation
  when appending files and fixes rare cases of when progress report was
  obvious wrong (e.g. stuck at 0% right until the end).
* MKVToolNix GUI: header editor: non-mandatory elements couldn't be removed
  anymore due to a regression while fixing 2320. They can now be removed
  again.

Recursive revbump from audio/pulseaudio

Log message:
mkvtoolnix: updated to 24.0.0

Version 24.0.0 "Beyond The Pale":

New features and enhancements
* mkvmerge: MP4 reader: improved the detection of edit lists consisting of two
  identical entries, each spanning the file's duration as given in the movie
  header atom. The second entry is ignored in such cases.
* mkvmerge: JSON identification: the "display unit" video track property is
  now reported as `display_unit`. The JSON schema has been bumped to v11 for
  this change.
* mkvmerge, mkvextract: AVC/h.264: empty NALUs will now be removed.
* mkvextract: VobSub extraction: empty SPU packets will now be dropped during
  extraction as other tools such as MP4Box cannot handle them
  correctly.

Bug fixes
* mkvmerge: E-AC-3 parser: fixed determining the number of channels for
  streams that contain an AC-3 core with dependent E-AC-3 frames.
* mkvmerge: Matroska reader: fixed mkvmerge buffering the whole file if a
  video track is multiplexed that consists of only one or a few frames.
* mkvmerge: the "display unit" video track property will now be kept \ 
if it is
  set in the source file.
* MKVToolNix GUI: multiplexer: when scanning playlists, all playlists were
  offered for selection regardless of the value of the "minimum playlist
  duration" setting.
* MKVToolNix GUI: multiplexer: deriving track languages from file names: the
  regular sub-expressions for ISO 639-1 codes could match on empty strings,
  too, causing matches in wrong places and hence no language being recognized
  in certain situations.
* MKVToolNix GUI: header editor: fixed a crash when saving the file fails
  (e.g. because it isn't writable).
* MKVToolNix GUI: header editor: the editor was wrongfully claiming that
  mandatory elements with default values cannot be removed in the "status"
  text.
* MKVToolNix GUI: preferences: on macOS & Linux the setting "enable copying
  tracks by their type" wasn't restored on program start.

Other changes
* Niels Lohmann's JSON library: the bundled version has been updated from
  v1.1.0 (git revision 54d3cab) to v3.1.1 (git revision g183390c1).
* pugixml library: the bundled version has been updated from v1.8 to v1.9

Log message:
mkvtoolnix: updated to 23.0.0

Version 23.0.0 "The Bride Said No":

New features and enhancements

* mkvmerge: input: format detection uses file-extension to improve performance
  and to give preference when several formats match.
* mkvmerge: AV1: added support for reading AV1 video from Open Bitstream Unit
  files.
* mkvmerge: AV1: adjusted the code for the AV1 bitstream format changes made
  up to 2018-05-02.
* mkvmerge: MP4 reader: if a track has an edit list with two identical
  entries, each spanning the file's duration as given in the movie header
  atom, then the second entry will now be ignored. Improves the handling of
  files with bogus data.
* MKVToolNix GUI: multiplexer: added options to only enable tracks of certain
  types by default.
* MKVToolNix GUI: multiplexer: added an option to enable dialog normalization
  gain removal by default for all audio tracks for which the operation is
  supported.
* MKVToolNix GUI: multiplexer: when deriving track languages from the file
  names is active and the file name contains the usual season/episode pattern
  (e.g. "S02E14"), then only the part after the season/episode pattern \ 
will be
  used for detecting the language.
* MKVToolNix GUI: multiplexer: the regular expression used for deriving track
  languages from the file names can now be customized in the preferences.
* MKVToolNix GUI: multiplexer: the user can now customize the list of track
  languages the GUI recognizes in file names. This list defaults to a handful
  of common languages instead of the full list of supported languages.

mkvtoolnix: updated to 22.0.0

Version 22.0.0 "At The End Of The World"

New features and enhancements
* mkvmerge, MKVToolNix GUI multiplexer: AC-3, DTS, TrueHD: added an option for
  removing/minimizing the dialog normalization gain for all supported types of
  the mentioned codecs.
* mkvmerge: AV1: added support for reading AV1 video from IVF, WebM and
  Matroska files.
* mkvmerge: FLAC: mkvmerge can now ignore ID3 tags in FLAC files which would
  otherwise prevent mkvmerge from detecting the file type.
* mkvinfo: the size and positions of frames within "SimpleBlock" and
  "BlockGroup" elements are now shown the same way they're shown for other
  elements (by adding the `-v -v` and `-z` options).
* MKVToolNix GUI: multiplexer: added options for deriving the track languages
  from the file name by searching for ISO 639-1/639-2 language codes or
  language names enclosed in non-word, non-space characters (e.g. \ 
"…[ger]…"
  for German or "…+en+…" for English).
* MKVToolNix GUI: info tool: implemented reading all elements in the file
  after the first cluster. Only top-level elements are shown; child elements
  are only loaded on demand.
* MKVToolNix GUI: info tool: added a context menu with the option to show a
  hex dump of the element with the bytes making up the EBML ID and the size
  portion highlighted in different colors. In-depth highlighting is done for
  the data in `SimpleBlock` and `Block` elements.
* MKVToolNix GUI: chapter editor: added an option to remove all end timestamps
  to the "additional modifications" dialog.

Bug fixes
* mkvmerge: MP4 reader: fixed reading the ESDS audio header atom if it is
  located inside a "wave" atom inside the "stsd" atom.
* mkvmerge: MP4 reader: AAC audio tracks signalling eight channels in the
  track headers but only seven in the codec-specific configuration will be
  treated as having eight channels.
* mkvmerge: MPEG TS reader: fixed wrong handling of the continuity counter for
  TS packets that signal that TS payload is present but where the adaptation
  field spans the whole TS packet.
* mkvmerge: the 'document type version' and 'document type read version'
  header fields are now set depending on which elements are actually written,
  not on which features are active (e.g. if a `SimpleBlock` is never written,
  then the 'read version' won't be set to 2 anymore).
* mkvmerge: the 'document type version' header field is now set to 4 correctly
  if any of the version 4 Matroska elements is written.
* mkvinfo: summary mode: the file positions reported for frames in
  `BlockGroup` elements did not take the bytes used for information such as
  timestamp, track number flags or lace sizes into account. They were
  therefore too low.
* mkvpropedit, MKVToolNix GUI header editor: the 'document type version' and
  'document type read version' header fields are now updated if elements
  written by the changes require higher version numbers.
* mkvpropedit, MKVToolNix GUI header editor: mandatory elements can now be
  deleted if there's a default value for them in the specifications.
* source code: fixed a compilation error on FreeBSD with clang++ 5.0.

Build system changes
* A compilation database (in the form of a file `compile_commands.json`) can
  be built automatically if the variable `BUILD_COMPILATION_DATABASE` is set
  to `yes` (e.g. as `rake BUILD_COMPILATION_DATABASE=yes`).

mkvtoolnix: updated to 21.0.0

Version 21.0.0 "Tardigrades Will Inherit The Earth"

New features and enhancements
* mkvmerge: track statistics tags: the TagDefault element will not be
  written anymore as it was always set to the default value 1
  anyway. Implements 2202.
* mkvmerge, MKVToolNix GUI: JSON files can now contain C++-style line comments
  outside of strings (e.g. something like this: // this is ignored). Such
  comments, even though not part of the official JSON specifications, are now
  ignored when reading JSON files.
* MKVToolNix GUI: chapter editor: opening a Matroska file without chapters in
  it will now open the file in an empty chapter editor instead of showing an
  error message. Implements 2218.
* MKVToolNix GUI: an "info" tool has been added, replacing the \ 
functionality
  of mkvinfo's GUI. The functionality is not on par yet but will be for
  release v22. Implements most of the functionality of 2104.

Bug fixes
* build system: configure was treating --disable-ubsan and
  --disable-addrsan the same as --enable-ubsan and
  --enable-addrsan.
* build system: an error message is output if a command to execute is not
  found instead of silently failing.
* build system: in addition to looking for the gettext C function and
  library, configure now also verifies the presence of the msgfmt program
  instead of simply relying on it.
* mkvmerge: appending files with additional parts at the same time was broken
  if more than one additional part was appended (e.g. when appending files
  from DVDs with something like '(' VTS_01_1.VOB VTS_01_2.VOB ')' + '('
  VTS_02_1.VOB VTS_02_2.VOB ')'). In such a situation the content from files
  VTS_02_1.VOB and VTS_02_2.VOB where laid out in parallel to the content
  from the earlier files.
* mkvmerge: FLV reader: a single invalid AAC frame was written for AAC audio
  tracks with codec initialization data longer than five bytes.
* mkvmerge: FLV reader: timestamps will be normalized down to 0.
* mkvmerge: MP4 reader: if an AAC track doesn't contain an AAC-specific
  decoder configuration in the ESDS portion, then a default decoder
  configuration will be generated based on the track's header data instead of
  skipping the track.
* mkvmerge: MP4 reader: fixed reading HEVC/h.265 video tracks if they're
  stored as Annex B byte streams inside MP4.
* mkvmerge: Ogg Opus reader: mkvmerge will now emit a warning instead of
  aborting when it encounters an Ogg Opus page with no data in the
  packet.
* mkvmerge, mkvextract: Matroska parser: fixed a segmentation fault that
  occurred whenever the first level 1 element after resyncing after an error
  in the file structure isn't a cluster.
* mkvmerge, MKVToolNix GUI multiplexer & header editor: fixed a crash during
  --enable-addrsan.
* build system: an error message is output if a command to execute is not

  in the file structure isn't a cluster.
* mkvmerge, MKVToolNix GUI multiplexer & header editor: fixed a crash during
  file type detection for attachments if MKVToolNix is installed in a path
  with non-ASCII characters (e.g. German Umlauts).
* mkvinfo: the --hex-positions parameter did nothing in summary mode.
* mkvinfo: Windows: line endings will be written as \r\n (carriage return &
  line feed) again instead of just \n (line feed).
* mkvpropedit: adding track statistics tags: for tracks with content encoding
  (compression) mkvpropedit is now accounting the uncompressed number of
  bytes, not the encoded (compressed) number of bytes.
* MKVToolNix GUI: multiplexer: the subtitle character set can now be set for
  appended subtitle files, too.
* MKVToolNix GUI: multiplexer: when appending, all tracks appended to disabled
  tracks will start out disabled, too.

Build system changes
* mkvinfo: the GUI portion has been removed. mkvinfo is now a pure
  command-line program again.
