* Tue Oct 30 2018 Ferdinand Thiessen <rpm@fthiessen.de>
- Update to version 28.2.0
* mkvmerge, mkvinfo, mkvextract, mkvpropedit, MKVToolNix GUI's info
tool & chapter editor: fixed a case of memory being accessed after
it had been freed earlier. This can be triggered by specially
crafted Matroska files and lead to arbitrary code execution. The
vulnerability was reported as Cisco TALOS 2018-0694 on 2018-10-25
(CVE-2018-4022). Fixes boo#1113709.
- Update to version 28.1.0
* mkvmerge: bugfix: AV1 parser: fixed an error in the sequence
header parser if neither the `reduced_still_picture_header` nor
the `frame_id_numbers_present_flag` is set.
bugfix: AV1 parser: when creating the `av1C` structure for the
Codec Private element the sequence header OBU wasn't copied
completely: its common data (type field & OBU size among others)
was missing.
bugfix: Matroska reader, AV1: mkvmerge will try to re-create the
`av1C` data stored in Codec Private when reading AV1 from
Matroska or WebM files created by mkvmerge v28.0.0.
* MKVToolNix GUI: bugfix info tool: the tool will no longer stop
scanning elements when an EBML Void element is found after the
first Cluster element.
- Update to version 28.0.0
* mkvmerge: New feature: AV1 parser: updated the code for the
finalized AV1 bitstream specification.
New feature: AV1 packetizer: updated the code for the finalized
AV1-in-Matroska & WebM mapping specification.
New feature: AV1 support: the `--engage enable_av1` option has
been removed again.
New feature: MP4 reader: added support for AV1.
New feature: DTS: implemented dialog normalization gain removal
for extension substreams.
New feature: VP9: mkvmerge will now create codec private data
according to the VP9 codec mapping described in the WebM
specifications.
bugfix: JSON identification: fixed a bug when removing invalid
UTF-8 data from strings before they're output as JSON.
bugfix: MP4/QuickTime reader: fixed handling of PCM audio with
FourCC `in24`.
bugfix: MPEG transport stream reader, teletext subtitles: the
decision whether or not to keep frames around in order to
potentially merge them with the following frame is made sooner.
That avoids problems if there are large gaps between teletext
subtitle frames which could lead to frames being interleaved
too late.
* mkvmerge, mkvextract: New feature: simple text subtitles:
added a workaround for simple text subtitle tracks that don't
contain a duration.
* mkvextract: New feature: added support for extracting AV1 to IVF.
New feature: IVF extractor (AV1, VP8, VP9): precise values will
be used for the frame rate numerator & denominator header fields
for certain well-known values of the track's default duration.
* MKVToolNix GUI: New feature: automatic scaling for high DPI
displays is activated if the GUI is compiled with Qt ? 5.6.0.
New feature: added a menu item ("Help" ? "System information") for
displaying information about the system MKVToolNix is running on
in order to make debugging easier.
New feature: multiplexer, header editor: the user can enter a list
of predefined track names in the preferences. She can later select
from them in "track name" combo box.
* mkvextract: bugfix: IVF extractor (AV1, VP8, VP8): the frame rate
header fields weren't clamped to 16 bits properly causing wrong
frame rates to be written in certain situations.
* mkvpropedit, MKVToolNix GUI's header editor: bugfix: fixed file
corruption when a one-byte space must be covered with a new EBML
void element but all surrounding elements have a "size length"
field that's eight bytes long already.
* Thu Oct 18 2018 Ferdinand Thiessen <rpm@fthiessen.de>
- Update to version 27.0.0:
* mkvmerge: New feature: chapters: the timestamps of chapters
read from containers or from chapter files can be adjusted
(multiplication and addition) with the new
`--chapter-sync` option or using the special track ID `-2`
for the existing `--sync` option.
Bugfix: AC-3: dialog normalization gain removal was corrupting
E-AC-3 frames irreversibly by writing checksums in places where
they didn't belong. Additionally only the first E-AC-3 frame in
a Matroska was processed but not additional dependent frames in
the same block.
* MKVToolNix GUI: New feature: multiplexer: adjusted & added
controls for mkvmerge's new feature of being able to adjust
chapter timestamps.
New feature: multiplexer: the GUI can now ask for confirmation
when the user is about to create a file that won't contain
audio tracks. It does this by default if at least one source
file contains an audio track.
Bugfix: fixed a leak of Windows font resources leading to a
general slowdown and subsequent crash.
- Update to version 26.0.0:
* mkvmerge: New feature: chapter generation: if the name template
given by `--generate-chapters-name-template` is empty, no names
will be generated for the chapter atoms.
New feature: chapters: chapter names generated from MPLS files
will now use the name template if one is set via
`--generate-chapters-name-template`.
New feature: mkvmerge will no longer abort with an error message
if no audio, video and subtitle tracks should be multiplexed.
This allows copying of chapters from non-chapter source files.
Bugfix: Matroska reader: fixed wrong timestamps when appending
Matroska files where the second Matroska file's first timestamp
is bigger than 0.
Bugfix: MP4 reader: fixed division by zero errors during file
identification if the timescale is 0 in the `MVHD` atom.
Bugfix: Windows Television DVR files are now recognized as an
unsupported file type. This prevents mis-detection as MPEG-2
with an accompanying flood of error messages.
* MKVToolNix GUI: New feature: the font size in the tool
selector on the left will scale with the font size the
user selects in the preferences.
New feature: the GUI will no longer automatically resize the
columns in tree and list views to match the content size.
Instead it remembers and restores the widths set by the user.
New feature: multiplexer: the chapter name template will now be
set automatically to the name template in the preferences'
"chapter editor" section. Additionally the option
`--generate-chapters-name-template ?` will be passed to
mkvmerge in situations when mkvmerge will generate chapters.
New feature: chapter editor: if the chapter name template is empty,
chapters will be generated without names.
New feature: chapter editor: added an option to remove all chapter
names to the "additional modifications" dialog.
Bugfix: info tool: under certain circumstances "cues" were shown at
the wrong level (inside the previous master element instead of on
lvel 1).
Bugfix: job queue: fixed invalid memory handling and consequent
crashes when using the "edit in corresponding tool & remove from
job queue" option if one of the files in that job contained
attached files.
* Wed Aug 08 2018 rpm@fthiessen.de
- Update to 25.0.0:
* mkvextract: New feature: VobSub extraction: empty SPU packets
will now be dropped during extraction as other tools such as
MP4Box cannot handle them correctly.
Bugfix: fixed a crash when mkvextract with a non-Matroska file as
the source file.
* MKVToolNix GUI: New feature:: multiplexer: added options to only
enable tracks of certain types by default.
New feature: multiplexer: added an option to enable dialog
normalization gain removal by default for all audio tracks for
which the operation is supported.
New feature: multiplexer: when deriving track languages from the
file names is active and the file name contains the usual
season/episode pattern, then only the part after the
season/episode pattern will be used for detecting the language.
New feature: multiplexer: the regular expression used for deriving
track languages from the file names can now be customized in
the preferences.
New feature: 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.
Bugfix: multiplexer: when scanning playlists, all playlists were
offered for selection regardless of the value of the "minimum
playlist duration" setting.
Bugfix: 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.
Bugfix: header editor: fixed a crash when saving the file fails
(e.g. because it isn't writable).
Bugfix: header editor: the editor was wrongfully claiming that
mandatory elements with default values cannot be removed in
the "status" text.
Bugfix: preferences: on macOS & Linux the setting "enable copying
tracks by their type" wasn't restored on program start.
Bugfix: the central area is now scrollable, allowing the GUI to be
resized to almost arbitrary sizes.
Bugfix: multiplexer: the "copy file title to destination file name"
functionality will now replace everything in the destination file
name up to the last period instead of only up to the first period.
* mkvmerge: New feature: 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.
New feature: 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.
New Feature: Matroska & MPEG transport stream readers: the encoding
of text subtitles read from Matroska files can now be changed
with the '--sub-charset' parameter.
New feature: 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.
New feature: 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.
New feature: AVC/h.264: empty NALUs will now be removed.
New feature: input: format detection uses file-extension to improve
performance and to give preference when several formats match.
New feature: AV1: added support for reading AV1 video from
Open Bitstream Unit files.
New feature: AV1: adjusted the code for the AV1 bitstream format
changes made up to 2018-05-02 (git revision d14e878).
New feature: 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.
Bugfix: AVC/h.264 and HEVC: fixed file identification failing
for certain elementary streams due to internal buffers not
being cleared properly.
Bugfix: MLP code: fixed various issues preventing MLP from being
parsed correctly.
Bugfix: 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.
Bugfix: 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.
Bugfix: 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.
Bugfix: audio packetizers: mkvmerge will now keep discard
padding values if they're present for packets read
from Matroska files.
Bugfix: 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).
Bugfix: E-AC-3 parser: fixed determining the number of channels for
streams that contain an AC-3 core with dependent E-AC-3 frames.
Bugfix: Matroska reader: fixed mkvmerge buffering the whole file if a
video track is multiplexed that consists of only one or a few frames.
Bugfix: the "display unit" video track property will now be kept if
it is set in the source file.
Bugfix: MP3 packetizer: removed a memory leak growing linearly with the
track's size.
Bugfix: VobSub packetizer: whenever a VobSub packet doesn't contain a
duration on the container level, mkvmerge will now set it from
the duration in the SPU packets. Before it was accidentally setting
the SPU-level duration to 0 instead.
Bugfix: track statistics tags: if writing the `Date` element is
deactivated via `--no-date`, the `_STATISTICS_WRITING_DATE_UTC`
isn't written either anymore.
Bugfix: removed several small, constant-size memory leaks.
Version: 22.0.0-bp150.1.3
* Mon Apr 09 2018 rpm@fthiessen.de
- Update to 22.0.0:
* mkvmerge: New feature: AC-3, DTS, TrueHD: added an option for
removing/minimizing the dialog normalization gain for all
supported types of the mentioned codecs.
New feature: AV1: added support for reading AV1 video from IVF,
WebM and Matroska files.
New feature: FLAC: mkvmerge can now ignore ID3 tags in FLAC
files which would otherwise prevent mkvmerge from detecting the
file type.
Bugfix: MP4 reader: fixed reading the ESDS audio header atom if
it is located inside a "wave" atom inside the "stsd" atom.
Bugfix: 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.
Bugfix: 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.
Bugfix: 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.
Bugfix: the 'document type version' header field is now set
to 4 correctly if any of the version 4 Matroska elements
is written.
* mkvinfo: New Feature: the size and positions of frames
within "SimpleBlock" and "BlockGroup" elements are now shown
the same way they're shown for other elements.
Bugfix: 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.
Bugfix: mandatory elements can now be deleted if there's a default
value for them in the specifications.
* 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.
Bugfix: 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.
Bugfix: 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.
Bugfix: chapter editor: added an option to remove all end
timestamps to the "additional modifications" dialog.
- Update to 21.0.0:
* mkvinfo: the GUI portion has been removed. mkvinfo is now a pure
command-line program again.
* mkvmerge: New feature: track statistics tags: the `TagDefault`
element will not be written anymore as it was always set to the
default value `1` anyway.
New feature: JSON files can now contain C++-style line comments
outside of strings. Such comments, even though not part of the
official JSON specifications, are now ignored when reading JSON
files.
Bugfix: Appending files with additional parts at the same time
was broken if more than one additional part was appended.
Bugfix: FLV reader: a single invalid AAC frame was written for
AAC audio tracks with codec initialization data longer than five
bytes.
Bugfix: FLV reader: timestamps will be normalized down to 0.
Bugfix: 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.
Bugfix: MP4 reader: fixed reading HEVC/h.265 video tracks if
they're stored as Annex B byte streams inside MP4.
Bugfix: 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.
Bugfix: 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.
Bugfix: fixed a crash during file type detection for
attachments if MKVToolNix is installed in a path with
non-ASCII characters (e.g. German Umlauts).
* MKVToolNix GUI: New Feature: 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.
New Feature: 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.
Bugfix: MKVToolNix GUI: Bugfix: multiplexer: the subtitle
character set can now be set for appended subtitle files, too.
Bugfix: MKVToolNix GUI: multiplexer: when appending, all tracks
appended to disabled tracks will start out disabled, too.
* mkvinfo: the `--hex-positions` parameter did nothing in summary mode.
Bugfix: mkvinfo: Windows: line endings will be written as `\r\n`
again instead of just `\n`.
* mkvpropedit: Bugfix: 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.
* Sun Jan 21 2018 rpm@fthiessen.de
- Update to 20.0.0:
* Feature removal: several deprecated features have been removed:
mkvmerge: the deprecated options `--identify-verbose`,
`--identify-for-gui`, `--identify-for-mmg` and
`--identification-format verbose-text`
all command line tools: support for the deprecated, old,
proprietary format used for option files
all command line tools: support for passing command line
options via the deprecated environment variables
`MKVTOOLNIX_OPTIONS`, `MKVEXTRACT_OPTIONS`, `MKVINFO_OPTIONS`,
`MKVMERGE_OPTIONS` and `MKVPROPEDIT_OPTIONS`
* mkvmerge: AVC/h.264 packetizer (framed): access unit delimiter
NALUs will now be removed.
bugfix: AVC/h.264 parser: when fixing the bitstream timing
information mkvmerge will now use exact representations of
the desired field duration if possible.
bugfix: AVC/h.264 parser: mkvmerge no longer assumes that
encountering sequence parameter set or picture parameter set
NALUs signal the start of a new frame.
bugfix: AVC/h.264 packetizer (framed): when mkvmerge is told
to fix the bitstream timing information, it will now update
all SPS NALUs, not just the ones in the AVCC.
bugfix: MPEG TS reader: TS packet payloads will only be
treated as PES packets if the payload actually starts with
a PES start code. The prior behavior led to wrong timestamps
and potentially broken frame data.
bugfix: MPEG TS reader: mkvmerge will now drop incomplete PES
packets as soon as an error is detected in the transport
stream instead of passing the incomplete frame to the
packetizer. An error is assumed either if the
`transport_error_indicator` flag is set or if the value of
the `continuity_counter` header field doesn't match the
expected value.
bugfix: Opus: when re-muxing Opus from Matroska mkvmerge will
now write "block duration" elements for all block groups
where a "discard padding" is set, too.
bugfix: SRT reader: mkvmerge can now handle SRT files with
timestamps without decimal places.
bugfix: read buffer I/O class: the class could get out of sync
regarding the file position of the underlying file I/O class
causing wrong data to be returned on subsequent read
operations. One result was that trying to identifying MPLS
files that refer to very short M2TS files caused mkvmerge
to segfault.
bugfix: multiplexer core: if there's a gap in audio timestamps,
a new block group/lace will be started for the first frame
after each gap. Before the fix the frame after the gap was
often stored in the previous block group causing the gap to
be in the wrong place: at the end of that block group.
* mkvextract: bugfix: AVC/h.264: if two consecutive IDR frames
with the same `idr_pic_id` parameter and no access unit
delimiters are found between them, mkvextract will insert an
access unit delimiter in order to signal the start of a new
access unit.
* MKVToolNix GUI: bugfix: update check dialog: Markdown links will
now be converted to clickable links.
* Mon Dec 25 2017 jengelh@inai.de
- Update to new upstream release 19.0.0
* 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.
* 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).
* 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.
* Tue Dec 12 2017 rpm@fthiessen.de
-Update to 18.0.0:
* mkvmerge: bugfix: 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.
bugfix: Matroska identification: the `date_local` and
`date_utc` attributes will only be output if the identified
Matroska file actually contains the "date" header field.
bugfix: WebVTT: mkvmerge did not recognize timestamp lines if
the hours components were absent.
enhancement: AVC & HEVC ES parsers: performance improvements
by copying much less memory around.
enhancement: 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.
* mkvpropedit: bugfix: 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.
* 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.
enhancement: 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.
* Wed Nov 08 2017 rpm@fthiessen.de
- Update to 17.0.0:
* The word "timecode" has been changed to "timestamp" everywhere.
This affects program output (including mkvinfo's), GUI controls,
command line parameters (e.g. `mkvmerge --timestamp-scale ?`) and
file formats.
All programs remain backwards compatible insofar as they still
accept "timecode" in all those places.
* mkvextract's command line interface has been changed to allow
extraction of multiple items at the same time.
* mkvmerge: New feature: AC-3: during identification regular AC-3
and E-AC-3 tracks will now be identified differently for most
container formats (exception: AVI, Real Media, Ogg/OGM).
The codec will be reported as `AC-3` for regular AC-3 and as
`E-AC-3` for E-AC-3 tracks instead of the combined `AC-3/E-AC-3`.
bugfix: AAC ADTS parser: mkvmerge will now parse the
`program_config_element` if it is located at the start of an AAC
frame in order to determine the actual number of channels.
This overrides invalid channel configurations in the ADTS headers.
bugfix: fixed AC-3 being misdetected as encrypted MPEG program
streams under certain conditions.
bugfix: Dirac: under certain conditions (e.g. only muxing a single
Dirac track without any other tracks) mkvmerge was always setting
the pixel width & height to 123. The frame rate was wrong, too.
bugfix: E-AC-3 in Matroska: if AC-3 cores and their corresponding
E-AC-3 extension are located in two different Matroska blocks,
then mkvmerge will now re-assemble them into a single block and
only use the first block's timestamp.
bugfix: SRT reader: fixed calculating the duration of entries
starting with at a negative timestamp.
bugfix: VC-1: under certain conditions (e.g. only muxing a single
VC-1 track without any other tracks) mkvmerge was always setting
the pixel width & height to 123. The frame rate was wrong, too.
bugfix: command line options: an error message will be output if
the single-value-form of the `--sync` option is used and it
isn't a number (e.g. `--sync 0:asd`).
* mkvpropedit, GUI's header editor: bugfix: both programs will now
show proper error messages instead of crashing when certain
kinds of data corruption is found when reading a file.
- Update to 16.0.0:
* mkvmerge: New feature MP4 reader: added support for Vorbis.
bugfix: AAC reader: mkvmerge will now emit an error message for
AAC files whose header fields imply a sampling frequency
or number of channels of 0.
bugfix: AVC/h.264 ES parser: fixed the calculation of reference
information for P and B frames. This also fixes some P frames
being marked as B frames and vice versa.
bugfix: AVC/h.264 ES parser: only non-key frames that have the
NALU header field `nal_ref_idc` set to 0 will be marked as
"discardable" in `SimpleBlock` elements. Other half of the
fix for #2047.
bugfix: HEVC/h.265: the generation of the HEVCC structure
stored in `CodecPrivate` was wrong in two places:
1. the position of the number of sub-layers was swapped with
reserved bits and 2. the VPS/SPS/PPS/SEI lists did not start
with a reserved 1 bit.
bugfix: output: the `doc type version` will be set at least
to 2 if certain elements are written (`CodecState`,
`CueCodecState`, `FlagInterlaced`).
bugfix: output: the track header attributes `MinCache` and
`MaxCache` will not be written anymore.
bugfix: Matroska reader: the "key" and "discardable" flags of
SimpleBlock elements will be kept as they are.
bugfix: Matroska reader: if present in the file,
the "white colour coordinate x" track header attribute was
written to both "white colour coordinate x" and
"white colour coordinate y" in the output file.
bugfix: Opus output: mkvmerge will now put all frames with
discard padding into their own block group.
* MKVToolNix GUI: Bugfix: header editor: removed the check for
external modification when saving the file.
bugfix: job queue: fixed calculation of total progress when
automatic removal of completed is enabled.
* Thu Aug 31 2017 rpm@fthiessen.de
- Update to 15.0.0:
* Requires libebml >= 1.3.5
* Dropped disable-update-check.patch (upstream now provides
configure option for disabling the update check).
* mkvmerge, mkvpropedit, GUI's header and chapter editors: the
programs will no longer add most missing Matroska elements that
are mandatory but have a default value in the Matroska
specification (e.g. the `TagLanguage` element with a value of
`und` if it isn't present in its `SimpleTag` parent).
* mkvmerge: the option `--colour-matrix` has been renamed to
`--colour-matrix-coefficients` in order to match the
specification more closely. The old option name will
continue to be recognized as well.
* all: bugfix: selecting the program's language (e.g. via the
`--ui-language`command-line option or via the GUI's
preferences) did not work on Linux & Unix if the `LANGUAGE`
environment variable was set and didn't include the desired
language.
* MKVToolNix GUI: new feature: multiplex tool: added a new entry
to the "source files" context menu labeled "Set destination
file name from selected file's name". It will force the GUI
to consider the selected file to be the reference for
automatically setting the file name, no matter which file was
originally added as the first file. It will also force setting
the destination file name once if automatic destination file
name generation is turned off in the preferences.
new feature: multiplex tool: added an option in the preferences
on "Multiplexer" ? "Output" labeled "Only use the first source
file that contains a video track". If enabled, only source
files containing video tracks will be used for setting the
destination file name. Other files that are added are ignore.
new feature: header editor: added support for editing the video
colour attributes.
new feature: header editor: added support for the "video
projection" track header attributes.
new feature: job queue: selected jobs can now be move up and
down by pressing the `Ctrl+Up` and `Ctrl+Down` keys.
Additionally, push buttons to move them up & down are shown
if the corresponding option is enabled in the preferences.
bugfix: removed the keyboard shortcuts for switching between
the different tools (e.g. `Ctrl+Alt+1` for the multiplexer).
They overlapped with basic functionality on keyboards that
use an `AltGr` key, e.g. German ones, where `AltGr+7` emits
`{`. As `AltGr+key` is implemented as `Ctrl+Alt+key` under the
hood, this means that `AltGr+7` is really `Ctrl+Alt+7` which
the GUI now took to mean "switch to the job queue" instead of
"insert `{`".
bugfix: header editor: after saving the file the GUI wasn't
updating its internal file modification timestamp. That lead
to the GUI wrongfully claiming that the file had been
modified externally when the user wanted to save the file
once more, requiring a reload of the file losing all
modifications made since saving the first time.
* mkvmerge: new feature: added support for the
"video projection" track header attributes.
bugfix: DTS handling: some source files provide timestamps for
audio tracks only once every `n` audio frames.
In such situations mkvmerge was buffering too much data
resulting in a single gap in the timestamps of one frame
duration after frame number `n - 1` (the second audio
timestamp read from the source file was used one output
frame too early).
* mkvinfo: new feature: added support for the
"video projection" track header attributes.
bugfix: fixed a null pointer dereference if an `EbmlBinary`
element's data pointer is a null pointer.
* mkvpropedit: new feature: added support for editing the
video colour attributes.
new feature: added support for the "video projection"
track header attributes.
* Fri Aug 25 2017 rpm@fthiessen.de
- Split boost-devel BuildRequires for Tumbleweed
- Update to version 14.0.0
* mkvmerge, mkvpropedit, MKVToolNix GUI (chapter editor):
new feature: added support for chapters in WebM files that is
spec-compliant by removing all tag elements not supported
by the WebM spec.
* translations: added a Romanian translation of the programs.
* mkvmerge: bugfix: AVC/h.264 and HEVC/h.265 parser: fixed wrong
frame order & timestamp calculation in certain situations when
SPS (sequence parameter sets) or PPS (picture parameter sets)
change mid-stream.
bugfix: MPEG-1/-2 video: the "remove stuffing bytes" feature
introduced in v5.8.0 was broken. In a lot of situations it
did not detect the end of a slice correctly and removed 0 bytes
that were actually part of the slice structure. Often there
were no visual problems as decoders were able to ignore such
errors, but in other cases there are visual artifacts upon
decoding. As detecting the slice end properly requires parsing
the whole slice structure, this feature has been removed again.
bugfix: MPEG PS reader: fixed mkvmerge trying to handle an "end"
code the same way as a "program stream map" code.
bugfix: MPEG TS reader: mkvmerge won't emit warnings if the
system's `iconv` library doesn't support the ISO 6937
character set.
bugfix: when appending fails the error message details (e.g.
"the number of channels differs: 1 and 2") were often not output.
new feature: AAC: implemented support for AAC with 960 samples per
frame.
new feature: identification: if the encoding/character set of a
text subtitle track is known (e.g. because a byte order mark is
present in the file), then it will be output during
identification as the `encoding` property.
new feature: WAV reader: added support for Wave64 files.
* MKVToolNix GUI: bugfix: multiplex tool: implemented a workaround
for a crash that could occur during drag & drop if at least one
of the columns is hidden.
bugifx: multiplex tool: appended tracks can no longer be enabled
(selected for multiplexing) if the track they're going to be
appended to is not enabled.
bugifx: multiplex tool: if the GUI is set to ensure unique output
file names, it will now verify that right before starting to
multiplex/adding the job to the queue, too.
bugifx: fixed the total progress reverting to 0% instead of
staying at 100% when all jobs have finished. This was introduced
by the attempt at fixing the computation of the value of total
progress bar for multiple jobs running.
new feature: multiplexer: if the encoding/character set of a
subtitle track cannot be changed, the GUI will deactivate the
"subtitle character set" drop-down box and ignore changes to it
when multiple tracks are selected. Additionally, if the track's
encoding is known and cannot be changed (e.g. due to a
byte order mark in the file), that encoding will be selected in
the drop-down box automatically. Both changes signal to the user
that she doesn't have to take care of the encoding herself.
new feature: chapter editor: added a function to the "additional
modifications" dialog for calculating and setting the end
timestamps.
new feature: changed the shortcuts for switching between the
various tools from `Alt+number` (e.g. `Alt+1` for the multiplexer
tool) to `Ctrl+Alt+number` in order to avoid clashing with
Windows' input method for arbitrary characters (pressing and
holding `Alt` and typing the codepoint on the number pad).
new feature: added a "Window" menu and entries with shortcuts for
selecting the next (`Ctrl+F6`) respectively previous tab
(`Ctrl+Shift+F6`) in the current tool.
* Thu Jul 13 2017 rpm@fthiessen.de
- Update to version 13.0.0
* mkvmerge: new feature: MPEG TS reader: information about
multiple programs will be output as container properties during
verbose/JSON identification.
bugfix: MP4 reader: MPEG-1/2 video read from MP4 files was written
with an invalid codec ID (e.g. `V_MPEG7`) in certain cases.
bugfix: MPEG PS reader: made the file type detection less strict
so that garbage at the start of the file doesn't prevent detection.
bugfix: MPEG PS reader: (E-)AC-3 tracks were not detected if the very
first packet for that track didn't contain a full (E-)AC-3 frame.
bugfix: MPEG TS reader: fixed mkvmerge not detecting all tracks in
MPEG transport streams containing multiple programs.
bugfix: MPEG TS reader: fixed track content being broken for some
tracks read from MPEG transport streams containing multiple programs.
bugfix: JSON identification: the `stream_id` and `sub_stream_id`
track properties were output as hexadecimal strings instead
of unsigned integers. As the `ts_pid` track property was only
used for MPEG transport streams, its value is now output as
`stream_id` instead, and the `ts_pid` property has been removed.
The JSON schema version has been bumped to 8 due to this change.
bugfix: fixed a crash when appending video tracks where one track
has a CodecPrivate member and the other one doesn't.
bugfix: track statistics tags: the `NUMBER_OF_BYTES` tag
is supposed to contain the number of bytes in a track before any
of the content encoding schemes such as lossless compression
is applied; however, mkvmerge was wrongfully using the number of
bytes after the schemes had been applied.
bugfix: CLPI & MPLS parsers: MPLS and CLPI files with version
number `0300` as used on Ultra HD Blu-ray Discs are
now accepted as well.
* MKVToolNix GUI: new feature: multiplex tool: added a column
"program" to the tracks list. Certain container types such
as MPEG transport streams can contain multiple programs.
The new column will contain the service name (think TV station
names such as "arte HD") for such streams.
bugfix: fixed computation of value of total progress bar for
multiple jobs running.
bugfix: multiplexer, adding new attachments: when the GUI checks
if there's an attachment with the same name it will now
disregard disabled attached files.
new feature: multiplex tool: the dialog asking the user what to
do with dropped files (add to current settings, add to new
settings etc.) now remembers the previous decision and defaults
to it the next time it's shown.
new feature: tabs can now be closed by pressing the middle mouse
button.
* mkvpropedit: bugfix: fixed a crash when the selector used
for `--tags` is invalid.
* Tue Jun 06 2017 olaf@aepfle.de
- Adjust usage of gccN-c++ for Leap42 and SLE12
* Tue May 30 2017 rpm@fthiessen.de
- Update to version 12.0.0
* MKVToolNix GUI: new feature: the key combination
Ctrl+Shift+Space will now toggle the selection of the current
item in all tree views where multiple selections are allowed.
new feature: chapter editor: added the extension `*.cue`
to the "open chapter file" dialog.
bugfix:preferences ? job actions, type "play audio file":
the GUI will no longer clear the audio file name input if the
user aborts the audio file selection dialog.
bugfix: multiplexer tool: the "show command line" dialog will no
longer include the mkvmerge executable's location as the first
argument for the two "MKVToolNix option files" escape modes.
bugfix: header editor: empty track language elements are now
treated the same as those set to invalid ISO 639-2 codes:
as if they were set to `und` = "undetermined".
new feature: watch jobs: the user can now have the GUI execute
an action once as soon as the current job or the whole queue
finishes. The actions are the same ones that can be configured
to be run automatically after job or queue completion.
new feature: implemented several built-in actions that can be
executed either on special events or once via the "watch jobs"
tool. These are: playing an audio file; hibernating, sleeping
and shutting down the computer.
new feature: multiplex tool: added a new option for what to do
after starting to multiplex/adding to the job queue:
"close current settings" will close the current multiplex
settings without opening new ones.
* mkvmerge: New feature: cue sheet parser: if the cue sheet
contains a non-empty `TITLE` entry and if no other segment title
has been set yet, then the segment title will be set to the
cue sheet's `TITLE` value.
new feature: added an option `--no-date` that prevents the "date"
field from being written to the segment information headers.
new feature: FLAC reader: added support for handling embedded
pictures as attachments.
new feature: MP4 reader: Added support for parsing the "COLR"
atom and including its values as track headers.
bugfix: HEVC/h.265 parser: fixed the superfluous copying of the
'bitstream_restriction_flag' and its dependent flags in the
VUI parameters of the sequence parameter sets if the timing
information is present, too.
bugfix: MPEG TS reader, AAC parser: the MPEG TS reader will now
force the AAC parser to use the multiplex mode that the MPEG TS
reader has detected. This prevents the AAC packetizer from
mis-detecting it in its own attempt to identify the mode.
bugfix: MPEG TS reader: valid MPEG transport streams that start
with an h.264/h.265 start code were not recognized as a
supported file type.
bugfix: MPEG TS reader: fixed a potential read access from
invalid memory addresses in the code parsing the program
map table (PMT).
bugfix: MPEG TS reader: if packets are encountered that belong
to a PID not listed in the program map table (PMT), mkvmerge
will attempt to determine their type and codec from the content.
This supported content types are AAC (ADTS only) and AC-3.
bugfix: MP4 reader: fixed finding and parsing the `colr` atom if
there are more than one video extension atoms and the `colr` atom
is not the first one.
bugfix: MP4 reader: the `nclx` colour type of the `colr` atom is
now recognized, too.
bugfix: AAC parser: fixed mis-detection of certain data as valid
ADTS AAC headers resulting in memory allocation failures.
bugfix: AVC/h.264 parser: mkvmerge will now ignore bogus timing
information in the sequence parameter sets.
bugfix: AVC/h.264 & HEVC/h.265 parsers: all trailing zero bytes
will now be removed from NALUs.
bugfix: HEVC/h.265 parser: fixed copying the
`bitstream_restriction_flag` and all dependent fields in the VUI
parameters of the sequence parameter sets.
bugfix: HEVC/h.265 parser: fixed the calculation of the number of
parameter set arrays in the HEVCC data structure stored in
CodecPrivate.
* mkvpropedit: bugfix: header editor: added support for editing the
"date" segment information field.
* Tue Mar 28 2017 rpm@fthiessen.de
- Update to new release 10.0.0
* mkvmerge: new feature AVC/h.264 and HEVC/h.265 parser: mkvmerge
will now drop all frames before the first key frame as they
cannot be decoded properly anyway.
new feature HEVC/h.265 parser: added a workaround for invalid
values for the "default display window" in the VUI parameters
of sequence parameter sets.
bugfix MP4 reader: fixed track offsets being wrong in certain
situations regarding the presence or absence of edit lists
('elst' atoms) & composition timestamps ('ctts' atoms).
bugfix MP4 reader: offsets in "ctts" are now always treated
as signed integers, even with version 0 atoms.
bugfix Matroska reader: fixed handling BlockGroups and
SimpleBlocks with negative timestamps.
bugfix MP3 packetizer: the MP3 packetizer will no longer drop
timestamps from source containers if they go backwards.
This keeps A/V in sync for files where the source was in sync
even though their timestamps aren't monotonic increasing.
bugfix AVC/h.264 parser: mkvmerge will now drop timestamps
from the source container if no frame is emitted for that
timestamp.
bugfix HEVC/h.265 parser: mkvmerge will now drop timestamps
from the source container if no frame is emitted for that
timestamp.
* mkvinfo: the timestamps of SimpleBlocks with negative
timestamps are now shown correctly.
* mkvextract: SSA/ASS: fixed extraction when the "Format"
line in the "[Events]" section contains less fields than the
default for SSA/ASS would indicate.
* Mon Feb 20 2017 rpm@fthiessen.de
- Update to new release 9.9.0
* mkvmerge: AC-3 handling: some source files provide timestamps
for audio tracks only once every n audio frames. In such
situations mkvmerge was buffering too much data resulting in
a single gap in the timestamps of one frame duration after frame
number n - 1 (the second audio timestamp read from the source
file was used one output frame too early).
bugfix MP4 reader: mkvmerge was only reading a small part of MP4
DASH files where the first "moov" "mdat" atoms occur before the
first "moof" atom.
bugfix MP4 reader: edit list ("edts" atoms) that are part of the
"moof" atoms used in MP4 DASH files weren't parsed. Instead the
edit lists from the main track headers inside the "moov" atom
were used.
bugfix MP4 reader: when an MP4 DASH file contained both normal
chunk offset table in their regular "moov" atoms, a
sample-to-chunk table ("stsc" atom) whose last entry had a
"samples per chunk" count greater than 1 and DASH "trun" atoms,
then mkvmerge was calculating wrong positions the frame content.
bugfix MP4 reader: mkvmerge couldn't deal with the key frame index
table having duplicate entries. The result was that only key
frames up to and including the first duplicate entry were marked
as key frames in the output file. All other frames weren't, even
though some of them were referenced from the key frame table
after the first duplicate entry.
bufix MP4 reader: when an MP4 file contained more than one copy of
the "moov" atom (the track headers etc.), mkvmerge was parsing
them all adding tracks multiple times.
bugfix MP4 reader: fixed an integer overflow during the timestamp
calculation leading to files with wrong timestamps. Such files
could not be played back properly by most players.
bugfix MPEG TS reader: if the PMT lists a DVBSUB track, mkvmerge
will now recognize it without having to find a packet for it
within the probed range.
bugfix splitting by parts (both the "timestamps" and the "frames"
variants): fixed the calculation of track statistics tags. When
calculating the duration the skipped portions weren't taken into
account leading to a too-high duration. As a consequence the BPS
tag (bits per second) was wrong, too.
bugfix reading files with DVB/HDMV TextSV subtitle tracks with
invalid CodecPrivate caused mkvmerge to abort with an error
from boost::format about the format string not having enough
arguments.
bugfix: fixed misdetection of certain AC-3 files as MP3 files
which led to an error message that
"the demultiplexer could not be initialized".
bugfix: fixed huge memory consumption when appending big Matroska
files with sparse tracks (e.g. forced subtitle tracks).
The Matroska reader will now queue at most 128 MB of data.
bugfix MP4 reader: the timestamps of all multiplexed tracks will
now be 0-based properly.
bugfix MP4 reader: the DTS-to-PTS offsets given by the "ctts"
atoms are now applied for all tracks containing a "ctts" atom,
not just h.264 & h.265 tracks.
* Some new features and enhancements
- Now required for man pages:
libxslt-tools, docbook-xsl-stylesheets and po4a
* Fri Jan 27 2017 rpm@fthiessen.de
- Update to new release 9.8.0
* mkvmerge: MP4 reader: when an MP4 file contained fewer entries
for timestamps than frames (which they never should), mkvmerge
would use 0 as the timestamp for all the other frames. This
resulted in effects such as the last frame of an output file
having a timestamp of 0 and in split files having a much longer
duration than they should have. Fixes #1847.
bug fix: the MPEG transport stream reader was using an outdated
format for the "CodecPrivate" element for HDMV TextST subtitles.
This has been updated to the current format which only contains
the "dialog style element". Existing Matroska files using this
outdated scheme can be fixed by running them through mkvmerge.
bug fix: files smaller than 4 bytes were wrongly identified as
MPEG transport streams.
bug fix: if a codec delay is set for a track in the input file,
it is kept. Fixes #1849. bug fix: fixed that the error message
"not enough space on disk" was shown twice on some operating systems.
teletext subtitle bug fix: fixed the handling of DVB teletext subtitles
signaled with data unit ID 0x02 and that contain pages from multiple magazines.
bug fix: when using --track-order without specifying all tracks,
the track numbers could end up in a way the user did not expect.
Now mkvmerge will always assign track numbers for those tracks
that are listed in --track-order first. The other tracks are
assigned numbers afterwards. Fixes the second part of #1832.
bug fix: when reading Matroska files the movie title was always
taken from the first Matroska source file, even if that file
didn't have a title set. Fixes one part of #1832.
MP4: fixed detection of MP3 audio when the object type ID in the
ESDS signals MP2 and the track headers have invalid values for
number of channels or sampling frequency. Fixes #1844.
The command line option "--check-for-updates" has been removed.
* GUI: the cache cleanup process that's run automatically when
the GUI starts no longer blocks file identification until it
is finished. Additionally the process will only be run once
per release of MKVToolNix. Fixes #1860.
certain failures during file identification that can be
traced to broken installations won't be stored in the cache
anymore. Without this fix the GUI would still use the cached
failed identification result even though the underlying
might have already been fixed.
multiplexer: changing default values in the preferences (e.g. the
default track language to set) did not affect files whose
identification results had already been cached.
multiplex tool bug fix: under certain circumstances the GUI was
creating invalid JSON files when starting to multiplex resulting
in an error message ("JSON option files must contain a JSON
array consisting solely of JSON strings").
re-worked the startup code not to use lock files when trying to
open a socket for communicating with an already-running instance.
This aims to prevent situations with stale lock files not being
cleaned up and the GUI not starting anymore as a result.
This might fix or prevent issues like #1805.
* A lot of new features and enhancements, please refer to NEWS.md
- Rebased disable-update-check.patch
- spec file cleanup
- Adjusted BuildRequires
* Since 9.7.1 QT >= 5.3 is required
* Since 9.7.1 a c++ compiler with some c++14 features is required
e.g. gcc >= 4.9 or clang >= 3.4
* Wed Nov 30 2016 rpm@fthiessen.de
- Update to new release 9.6.0
* mkvmerge: bug fix: mkvmerge was entering endless loops under
certain conditions when appending files.
MPLS parser bug fix: fixed reading the "in" & "out"
timestamps for "play items". This bug resulted in mkvmerge
not reading the correct range from the referenced M2TS file
under certain rare circumstances.
* MKVToolNix GUI: job output tool bug fix: the button for
acknowledging warnings & errors wasn't properly disabled when
the user used outside methods of acknowledging them
* mkvextract: VobSub bug fix: mkvextract will add a "langidx"
line to the .idx file upon extraction.
* mkvmerge & mkvextract: added support for HDMV TextST subtitles.
* Thu Oct 27 2016 rpm@fthiessen.de
- Update to new release 9.5.0
* mkvmerge: bug fix: The Ogg/OGM reader did not recognize Opus
files with comment headers anymore.
WAV reader bug fix: the track properties (channels, samplerate)
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.
WAV reader bug fix: fixed detection and merging of DTS in WAV
that uses the 14-bytes-in-16-bytes packing method.
MPEG transport stream reader bug fix: fixed mis-detection of
certain h.264 files as MPEG transport streams.
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.
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.
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.
* mkvprpedit, MKVToolNix GUI: Added support for "field order"
video track header element.
- Use GPG signature for verification.
* Fri Sep 16 2016 rpm@fthiessen.de
- Update to new release 9.4.2:
* mkvmerge: bug fix: using very large --sync values with certain
container formats was causing mkvmerge to abort muxing.
bug fix: fixed an invalid memory access (use after free)
during global destruction phase.
bug fix: HEVC parser: fixed three invalid memory accesses.
bug fix: MP4 reader: fixed an invalid memory access
bug fix: AAC reader: fixed mkvmerge throwing an uncaught
exception due to the sample rate being 0.
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.
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.
* Thu Sep 01 2016 rpm@fthiessen.de
- Update to new upstream release 9.4.0:
* 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.
chapter editor bug fix: overly long chapter names don't cause
the GUI's window to become overly wide anymore.
* mkvmerge: bug fix: mkvmerge does no longer emit a warning if no
comment header packet is found when reading tracks from
Ogg/OGM files.
bug fix: VP8 in Ogg: fixed dropping the first frame and the
timestamp calculation.
bug fix: when appending files mkvmerge wasn't starting clusters
on video key frame anymore for the first and all following
appended files.
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.
* 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.
* Some enhancements, please refer to the changelog within the
package.
* Fri Jul 15 2016 rpm@fthiessen.de
- Update to new upstream release 9.3.1:
* libebml >= 1.3.4 and libmatroska >= 1.4.5 are now required
* A lot of bugfixes and new features, new mkv elements are
supported, for a list of all changes, please refer to the
changelog provided by the package.
* Tue May 31 2016 rpm@fthiessen.de
- Update to new upstream release 9.2.0:
* mkvmerge: bug fix: the "interval" chapter generation mode was
always creating one chapter too many.
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.
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.
* 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.
* 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".
* Some other improvements, some enhancements and other bugfixes,
please refer to the changelog file provides with the package.
* Mon Apr 25 2016 rpm@fthiessen.de
- Update to new upstream release 9.1.0:
* mkvmerge: bug fix: AVC/h.264: fixed handling of interlaced frames
with bottom field first.
bug fix: mkvmerge will no longer abort reading a Matroska file
with a structural error right before the first cluster.
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).
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.
* MKVToolNix GUI: bug fix: Fixed huge memory consumption in the
JSON library by updating said JSON library.
bug fix: In merge-tool: 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.
