Changelog for mkvtoolnix-77.0-310.1.x86_64.rpm :

* Sun Jun 04 2023 Luigi Baldoni - Update to version 77.0 New features and enhancements:
* mkvmerge: tracks in the destination file will now be sorted by their type automatically unless the track order is specified with the `--track-order` option. The order is as follows: video tracks first followed by audio & subtitle tracks with other rarely used types of tracks last. Tracks of the same type will be sorted in the same order as their source files occur in the command-line arguments. Note that this doesn\'t affect file identification.
* MKVToolNix GUI: multiplexer: the default list colors used for distinguishing source files does not include the darkest tier anymore (the ones where one or two components are set to the value 0x3f) as they\'re hard to distinguish from each other. Only affects new installations, or when the user presses the \"reset to default colors\" button.
* MKVToolNix GUI: multiplexer: the GUI will now check the state of the \'track enabled\' flag of all video, audio & subtitle tracks when starting to multiplex or adding a job to the job queue. If there\'s no track with its flag turned on for a type, the GUI will turn on the flag for the first track of the type. This behavior can be turned off in the preferences.
* MKVToolNix GUI: header editor: the columns in the tracks/attachments view and the values on the \"track type\" page will now be updated each time a corresponding property is changed (e.g. when a track\'s name is changed) instead of showing what\'s in the file on disk.
* MKVToolNix GUI: Windows: a new settings in the preferences lets the user chose whether to use the light or the dark color palette, or to follow the system settings. Bug fixes:
* Fixed compilation with fmt v10.0.0.
* mkvmerge: fixed several instances of wrong format strings for `fmt::format` used in debug messages.
* mkvmerge: AV1 packetizer: the packetizer did not honor the aspect ratio (factor) given on the command-line via the `--aspect-ratio` or `--aspect-ratio-factor` options.
* mkvmerge: JSON identification: cropping parameters are reported again even if some of the four values are not present in the file or set to 0.
* MKVToolNix GUI: the defunct \"disable the dark mode\" checkbox was removed from the preferences.
* MKVToolNix GUI: language dialog: under certain conditions the controls for the individual components remained disabled when the dialog is opened even though editing of individual components is selected.
* MKVToolNix GUI: language dialog: the controls for the individual components weren\'t re-initialized properly after opening the dialog for the second & all following times, potentially leaving previously selected/entered entries intact, primarily when editing multiple tracks at once.
* MKVToolNix GUI: header editor: using the actions from the \"modify selected track\" context menu only worked if the user right-clicked on the first column in the view. They now work for clicks on any of the columns.
* MKVToolNix GUI: header editor: some of the actions toggling specific flags from the \"modify selected track\" did not work correctly if the flag wasn\'t currently present in the file, especially if the underlying value has a default value in the Matroska specs. Build system changes:
* The bundled `fmt` library was updated to v10.0.0.
* MKVToolNix GUI now uses an external Qt resource file instead of compiling it into the executable. The resource file has reached a size at which the C++ compiler exhausts available virtual memory on some 32-bit architectures. The GUI will look for the file in the directory set with `configure`\'s `--datadir` parameter on other systems (which usually means `/usr/share/mkvtoolnix`). The `install` build system commands installs it into that folder.
* Sun Apr 30 2023 Luigi Baldoni - Update to version 76.0 Important notes:
* mkvmerge: removed the option `--blockadd`. Removing block additional data is not possible anymore, as it is often required for proper decoding. New features and enhancements:
* mkvmerge: JSON file identification: added a child element called `num_index_entries` to the `properties` track element containing the number of index entries found for a track. Currently only implemented for Matroska files where it contains the number of cue points.
* mkvmerge: the maximum block addition ID track header value is now calculated automatically from both the existing mappings & the actually used block additions in the block groups.
* mkvmerge: Matroska reader: when reading WebM files that use block additions with ID 4 (HDR for VP9) an appropriate block addition mapping will be created automatically.
* mkvmerge: MP4 reader: the title/movie name meta data (content of the `udta.meta.ilst.©nam` atom) will now be copied over as the segment title track header attribute.
* mkvmerge: MP4 reader: the comment & encoder meta data (content of the `udta.meta.ilst.©cmt` & `….©too` atoms) will now be copied over as global tags `COMMENT` & `ENCODER` respectively.
* mkvmerge, MKVToolNix GUI\'s multiplexer: added an option to stop processing after the primary video track ends called `--stop-after-video-ends`. This discards any remaining packets of other tracks.
* MKVToolNix GUI: multiplexer: automatically setting the destination file name: added an option in the preferences for using the first source file\'s directory name instead of its file name as the basis for the destination file name.
* MKVToolNix GUI: multiplexer: double-clicking on certain columns in the \"tracks\" view will now toggle them directly (columns \"Default track\" & \"Forced track\") or activate the corresponding control (columns \"Language\", \"Name\" & \"Delay\"). Double-clicks on other columns will do what they\'ve done before, too: toggling the \"Copy item\" state.
* MKVToolNix GUI: the dialog for editing language tags is now created only the first time the user wants to edit a language tag & cached afterwards instead of creating a new instance each time. This makes subsequent uses instant. Bug fixes:
* mkvmerge: mkvmerge will now only try to probe for VobSubs if the name of the file to identify ends in either `.idx` or `.sub`, preventing mis-identification of other file types if VobSubs with the same base name exist in the same directory.
* mkvmerge: AC-3: mkvmerge will now skip certain types of garbage data (16 bytes starting with 0x01 0x10) that can occur before each sync frame, fixing the file not being identified as AC-3.
* mkvmerge: Matroska reader: when reading files that use block additions with IDs other than 1 (e.g. 4 for HDR for VP9) the IDs will now be kept & written to the output file. Before no ID would be written, effectively using 1 as that\'s the default value for the corresponding element.
* mkvmerge: mkvmerge will no longer write block addition mappings or the max block addition ID track header elements when creating a WebM file as those elements aren\'t supported there.
* mkvpropedit: fixed replacing chapters & tags in files that don\'t contain tracks.
* Sun Mar 26 2023 Luigi Baldoni :- Update to version 75.0.0 New features and enhancements:
* mkvmerge: MP4 reader: mkvmerge will now read Timed Text (FourCC `tx3g`) subtitle tracks & convert them on the fly to Matroska\'s simple text subtitle format (`S_TEXT/UTF8`; text only, no styles). Bug fixes:
* all: switched back to using `boost::filesystem` functions for creating directories instead of the ones introduced to work around bugs in `std::filesystem`. The latter didn\'t work correctly with UNC paths after the switch to `boost::filesystem::path` in v74.
* mkvmerge: VobSub reader: mkvmerge will now probe the `.idx` file during VobSub identification even if the `.sub` file is passed as the source. Avoids mis-detection of the `.sub` as MPEG program streams.
* MKVToolNix GUI: the GUI could abort with an exception on startup while looking for the `mkvmerge` or `mediainfo` executables due to inaccessible folders.
* MKVToolNix GUI: preferences: when opening the preferences the first time the UI might pre-select the first entry in the list of interface languages if the operating system\'s language is not available for MKVToolNix. This might also happen on Linux if e.g. `en_GB` is set, even though `en_US` is available. Now English (`en_US`) will be selected instead.
* MKVToolNix GUI: multiplexer: when adding files the GUI has special handling for chapter/tags/segment info files. This is done by comparing their content to certain patterns. This recognition could wrongfully be triggered if any such file was embedded in another file verbatim, e.g. with a chapter XML file attachment in a Matroska file. When trying to add that Matroska file, the GUI would treat it as a chapter file instead of a regular one. This content-based detection was fixed. Other changes:
* mkvpropedit, GUI\'s header editor: removed support for the deprecated \"minimum cache\" & \"maximum cache\" track header elements.
* Thu Mar 16 2023 Max Lin - Requires qt6-multimedia in Leap 15.5
* Sun Feb 12 2023 Luigi Baldoni - Update to version 74.0.0 New features and enhancements:
* mkvmerge: SRT handling: added a hack called `--engage keep_whitespaces_in_text_subtitles` which disables stripping whitespaces from the start & end of each line of SRT entries during muxing. Bug fixes:
* all: Windows: UNC paths of type `\\\\?\\C:\\…` are supported again by switching back to Boost\'s file system library instead of using C++17\'s file system library.
* mkvmerge: AVC/H.264 & HEVC/H.265 packetizers: when appending tracks the pixel dimensions will be checked & muxing will be aborted if they don\'t match.
* mkvmerge: file type detection: file types that can be detected unambiguously by their content (e.g. Matroska, MP4, WAV…) will now preferred in the detection order over file types based on their extension. Prevents certain cases of mis-detection, e.g. DTS in WAV but with a file name extension of `.dts` being detected as the wrong type of DTS.
* mkvmerge: SRT handling: whitespaces will now be stripped from the start & the end of each line of each entry, not just from the end of the last line.
* mkvextract: SRT extraction: whitespaces will not be stripped from the start & end of the whole entry anymore.
* MKVToolNix GUI: multiplexer: when adding multiple files that include certain file types (chapters, segment info and tag files) and when the choice where to add them is \"all files to a single new tab\", these certain file types will now be added in the newly added tab as well instead of the current tab that had already been open.
* build system: fixed compatibility with Ruby 3.2.0 by using `FileTest.exist?` instead of `File.exists?`, `Dir.exists?` & `FileTest.exists?` which were removed in that release. Build system changes:
* MKVToolNix is now using & requiring Boost\'s \"file system\" and \"system\" libraries again instead of C++17\'s file system library. This is due to gcc\'s library not supporting UNC paths of types `\\\\?\\C:\\dir\\file.ext`.
* Tue Jan 03 2023 Luigi Baldoni - Update to version 73.0.0 New features and enhancements:
* mkvmerge: greatly enhanced the speed of Base64 decoding which is used used e.g. when reading pictures embedded in Ogg or FLAC files or for binary data inside XML chapter & tag files. Even small blocks of data could take unreasonably long.
* mkvmerge: added support for reading HEVC/H.265 video from FLV containers. Bug fixes:
* mkvmerge: splitting: fixed a typo in the string output in GUI mode regarding the timestamps before which splitting was done.
* MKVToolNix GUI: job output: after having run multiple jobs the \"Clear output\" functionality only reset the visible parts. However, using the \"save output\" function would also save the output generated before the user used \"clear output\". Now only the output after the last use of \"clear output\" is saved.
* build system: when probing for the FLAC library the Ogg libraries will be linked with the compiled test program as well. This fixes detection if the `pkg-config` settings for FLAC don\'t list Ogg & the linker doesn\'t find the library automatically.
* Sun Nov 13 2022 Luigi Baldoni - Update to version 72.0.0 New features and enhancements:
* mkvmerge: AV1 parser: the variable-width OBU size field will be re-written with minimal length if it\'s encoded longer than necessary.
* mkvmerge: when splitting is active the program will output the timestamps actually used for making the decision when to split. If GUI mode is active, a specially formatted line `#GUI#splitting_before_timestamp ` is output as well. Lines prefixed with`#GUI#` are suitable for machine parsing, won\'t be translated and are guaranteed not to change in format.
* MKVToolNix GUI: multiplexer: when dragging & dropping directories to the \"attachments\" tab, the files contained in those directories will be attached.
* MKVToolNix GUI: info tool: added information about the file (directory, size, modification timestamp) at the top of each tab. Bug fixes:
* mkvmerge: AV1 parser: fixed the parser completely aborting when parsing the OBU size field fails due to there not being enough data to parse. Instead the parser will remember the last known-good position & restart from there after more data is available.
* mkvmerge: HDMV PGS subtitles: reverted the change that implemented a heuristic for detecting bogus timestamps & attempting to fix them. This was done to fix #3268. Unfortunately this affected valid subtitle files with intentional huge gaps in timestamps, e.g. forced subtitle tracks. The heuristic has simply been removed.
* mkvmerge: Matroska reader: fixed reading files with EBML Void elements before the Matroska Segment element.
* mkvmerge: fixed reversed attachment selection: `--attachments !4` would not copy any attachment instead of all attachments but the one with ID 4.
* mkvextract: IETF BCP 47/RFC 5646 language tags: mkvextract will now use & prefer IETF BCP 47 track language elements if they\'re present. Only affects the VobSub & USF subtitle extraction.
* mkvpropedit, MKVToolNix GUI\'s chapter & header editors: updated the list of deprecated Matroska elements. The applications will no longer try to write those elements, even if they\'re found in the file to be modified. The programs will no longer abort with error messages such as `assertion \"false\" failed`.
* mkvpropedit, MKVToolNix GUI\'s chapter & header editors: when the Matroska version numbers stored in the EBML Head element are updated, the updated EBML Head element might be smaller than the existing one. In that case the programs used to shrink the EBML Head & write a small EBML Void element between the updated EBML Head & the following element, usually a Matroska Segment element. This isn\'t widely supported by programs including MKVToolNix itself, causing them to declare such files as invalid. The programs will now create the EBML Void element inside the EBML Head element, making them a level 1 element instead of a level 0 element.
* mkvpropedit, MKVToolNix GUI\'s chapter & header editors: often the programs have to relocate the Master elements in which the modifications were done. In that case the Seek Head elements must also be updated to reflect to the Master elements\' new positions. If a file contained a Seek Head element at the start already and if that Seek Head was too small to contain the updated positions, the programs would end up in an endless loop trying to write data to the end, creating ever-growing files. This is now handled properly by voiding this too-small Seek Head & finding a proper space for a new one instead.
* MKVToolNix GUI: header editor: fixed pixelated icons on higher display scaling values. Build system changes:
* bug fix: libFLAC detection is now done via `pkg-config`, and the corresponding compiler flags are honored. Fixes static compilation with newer versions of libFLAC with MXE where a compiler definition is required to signal that it libFLAC wasn\'t built as a DLL.
* Sun Oct 09 2022 C J - Update to version 71.1.0 Bug fixes:
* Chapters DTD: added the new edition & chapter elements from Matroska v5.
* Chapters DTD: fixed EditionUID being mandatory. mkvmerge can auto-generate it if it\'s missing from the XML file.
* Chapters DTD: fixed the `example-chapters-1.xml` not validating against the DTD.
* Chapters DTD: corrected the old name `EditionManaged` to `EditionFlagOrdered`.
* Chapters DTD: fixed `ChapLanguageIETF` missing its element declaration & `ChapterLanguage` being required.
* XML DTDs: fixed elements representing binary data not allowing the `format` attribute.- Add Qt multimedia as a requirement for the GUI as it doesn\'t run without it.
* Sun Oct 09 2022 C J - Update to version 71.0.0 New features and enhancements:
* mkvmerge, MKVToolNix GUI\'s multiplexer: added support for the Emphasis audio track header element via the `--audio-emphasis` option. It is also read from Matroska files.
* mkvmerge: the options `--list-stereo-modes` and `--list-audio-emphasis` have been added to list all support numerical & textual values for the `--stereo-mode` & `--audio-emphasis` options.
* mkvpropedit, MKVToolNix GUI\'s header editor: added support for the Emphasis audio track header element via the `emphasis` property.
* MKVToolNix GUI: multiplexer: when the track properties are configured to be displayed in a tab widget below the files & tracks in the \"Input\" tab, the \"Color information\" tab will be laid out in two columns. This reduces the minimum height the whole tab widget requires. Implements #3401.
* MKVToolNix GUI: greatly sped up closing the preferences dialog by only re-running certain initialization functions when their corresponding settings have changed. Also fixes issues such as [#3406].
* mkvinfo, MKVToolNix GUI\'s info tool: added support for the following new elements from Matroska v5: Emphasis audio track header element; Chapter Skip Type; Edition Display; Edition String; Edition Language IETF.
* mkvmerge, mkvpropedit: added support for the following new chapter elements from Matroska v5: Chapter Skip Type; Edition Display; Edition String; Edition Language IETF. The GUI\'s chapter editor will receive support for them in the next release. Bug fixes:
* mkvmerge: Ogg/OGM reader: mkvmerge will now correctly skip tracks of unsupported types as well as tracks for which all track header pages haven\'t been found. Fixes #3394.
* Wed Aug 17 2022 Luigi Baldoni - Switch to Qt6 build for Tumbleweed (fixes boo#1202446)
* Sun Aug 14 2022 Luigi Baldoni - Update to version 70.0.0 New features and enhancements:
* MKVToolNix GUI: the user can now control where the job queue files & the preferences INI file are stored via environment variables. If set, the variable `MKVTOOLNIX_GUI_STATE_DIR` can point to a directory where the GUI stores both the job queue sub-directory and the preferences INI file. If you only want to relocate the preferences INI file, you can store the desired file name for the INI file in `MKVTOOLNIX_GUI_CONFIG_FILE`.
* MKVToolNix GUI: when adding directories via drag & drop/copy & paste the GUI will now offer the user the option to create one multiplex settings tab per directory & adding all files from that directory to the corresponding, newly created tab. Bug fixes:
* mkvmerge: AV1 OBU parser: fixed identifying files that only contain single frame.
* MKVToolNix GUI: multiplexer: when reading color parameters from identified files that are floating point numbers (minimum/maximum luminance, projection pitch/roll/yaw) the numbers will be formatted in floating-point notation instead of scientific notation as mkvmerge only supports the former.
* MKVToolNix GUI: multiplexer: color parameters that are floating point numbers (minimum/maximum luminance, projection pitch/roll/yaw) will only be set to a value during identification if the identification actually contains the property, and not to 0 anymore if it doesn\'t.
* Sat Jul 09 2022 Luigi Baldoni - Update to version 69.0.0 Important notes:
* all: the spelling of \"colour\" was changed to \"color\" throughout all programs to match the use of American English spelling in MKVToolNix. New features and enhancements:
* MKVToolNix GUI: the number of recently used entries (e.g. destination directories) remembered by the GUI can now be configured in the preferences.
* MKVToolNix GUI: multiplexer: when adding files the track properties regarding color information & color mastering meta information will be parsed & set in the corresponding GUI controls.
* MKVToolNix GUI: job queue: the job queue can now be sorted by clicking on the column headers.
* MKVToolNix GUI: job queue: when loading jobs from the queue directory that weren\'t previously known to the program those jobs will be sorted by their \"date added\" timestamp instead of using the order the operating system returns them in. Bug fixes:
* build system: fixed compilation with fmt v9.
* mkvmerge: HEVC ES parser: the parser will now parse at least the first full access unit before reporting that it has found all the required headers. Otherwise parsing might stop in the middle of the access unit due to the source reader not providing more data in the first call, leading to the parser not finding the `unspec62` and `unspec63` NALUs required for Dolby Vision.
* MKVToolNix GUI: preferences: the default actions added to the \"execute programs\" section on new installations now default to use WebM file names instead of Ogg, matching the format of the included audio files. Build system changes:
* The bundled `fmt` library was updated to v9.0.0.
* Mon May 23 2022 Luigi Baldoni - Update to version 68.0.0 New features and enhancements:
* mkvmerge: HDMV PGS subtitles: mkvmerge now tries to detect bogus timestamps (where the current timestamp is two hours or more after the previous timestamp) & correct them to something more sensible (1s after the previous timestamp). That way one bogus timestamp cannot cause the rest of the frames to not be interleaved properly with the other audio & video packets.
* mkvmerge: added colour information, colour mastering meta information & video projection information properties to the JSON identification format. The properties are reported for container types for which mkvmerge supports reading them (Matroska & MP4). The JSON identification format version number has been bumped to v15.
* MKVToolNix GUI: multiplexer: added controls for all the video colour information & the video projection information. Bug fixes:
* mkvmerge: SRT reader: entries with a duration of 0 or less will now be skipped.
* mkvpropedit, MKVToolNix GUI\'s chapter & header editors: fixed an invalid memory access when trying to update existing Matroska files whose EBML Head element had a \"size\" field length of eight bytes, and where rewriting said element would shrink the element by one byte. Files created by gstreamer fit the first part whereas the second depends on the changes requested by the user.
* mkvpropedit, MKVToolNix GUI\'s chapter & header editors: fixed the programs not handling having to remove EBML void elements at the end of the file correctly and consequently aborting.
* MKVToolNix GUI: the GUI now uses almost all SVG icons, allowing proper scaling even for scaling factors such as 125%.
* MKVToolNix GUI: when compiled with Qt 5 the character set of INI files is forced to UTF-8 in order to fix reading INI files written by a version compiled with Qt 6. Build system changes:
* Qt\'s SVG library is now required.
* Sat Apr 16 2022 Luigi Baldoni - Update to version 67.0.0 New features and enhancements:
* all: IETF BCP 47/RFC 5646 language tags: when deriving the legacy language element codes to use a language tag\'s ISO 639 code is also potentially interpreted as an & its prefix is used as the legacy language code. For example, \"Yue Chinese\" = `yue` is not part of ISO 639-2. However, there is an extlang subtag `yue` with a valid prefix of `zh` (\"Chinese\"), and for \"Chinese\" there is an ISO 639-2 language code: `chi`. In this example the IETF language element would be set to `yue` and the corresponding legacy element to `chi`.
* all: IETF BCP 47/RFC 5646 language tags: grandfathered language tags are now supported.
* all: IETF BCP 47/RFC 5646 language tags: all deprecated subtags from the IANA language subtag registry are now supported.
* all: IETF BCP 47/RFC 5646 language tags: all lists of valid subtags have been updated from their respective authoritative sources.
* all: IETF BCP 47/RFC 5646 language tags: all in the IANA language subtag registry are now supported, even those marked as deprecated and of type \'grandfathered\'.
* all: IETF BCP 47/RFC 5646 language tags: reduced the maximum number of extended language subtags that are present in a valid tag from 3 to 1 in compliance with RFC 5646 section 2.2.2.
* all: IETF BCP 47/RFC 5646 language tags: all language codes reserved for private/local use (`qaa`–`qtz`) are now supported.
* all: IETF BCP 47/RFC 5646 language tags: Digital Cinema Naming Convention language codes that fall into the IETF BCP 47 range of \"private use\" tags (`qaa`–`qtz`) are now replaced by their IETF BCP 47 equivalents during normalization (e.g. `QMS` → `cmn-Hans`).
* all: added a new translation to Chinese Simplified (Singapore) by Dian Li.
* mkvmerge, mkvpropedit: added a new command line option called `--enable-legacy-font-mime-types`. With this option on the two programs will use the same legacy MIME types for fonts whenever new attachments are added (both programs), when reading existing attachments (only `mkvmerge`) or when replacing existing ones (only `mkvpropedit`).
* mkvmerge, mkvpropedit: IETF BCP 47/RFC 5646 language tags: added a command line option `--normalize-language-ietf ` which turns on normalization of IETF BCP 47 language tags to either their canonical (mode `canonical`) or extended language subtags form (mode `extlang`) or turns it off (mode `off`). If the option isn\'t given, language tags will now be normalized to the canonical form.
* MKVToolNix GUI: IETF BCP 47/RFC 5646 language tags: ISO 639-3 and 639-5 languages will now be used by default.
* MKVToolNix GUI: IETF BCP 47/RFC 5646 language tags: the language editor dialog will now show warnings in several cases: when deprecated tags are used; when the tag\'s canonical and/or extlang forms differ from the user input.
* MKVToolNix GUI: IETF BCP 47/RFC 5646 language tags: the language editor now has a button to replace the current tag with a normalized form (canonical or extlang) if those differ from the current tag.
* MKVToolNix GUI: IETF BCP 47/RFC 5646 language tags: added an option in the preferences to always normalize all language tags to their canonical or extlang forms or to turn normalization off. Can also be enabled from the language editor dialog.
* MKVToolNix GUI: IETF BCP 47/RFC 5646 language tags: the language dialog now shows a warning if a variant is used with a prefix that isn\'t in the variant\'s list of suitable prefixes. It\'ll also say if the corresponding canonical/extlang forms would have a suitable prefix.
* MKVToolNix GUI: IETF BCP 47/RFC 5646 language tags: the language dialog now shows a warning if a script is used with a language for which it should be suppressed.
* MKVToolNix GUI: multiplexer: the track property group boxes in the scrollable pane are now collapsible & expandable, saving their state over restarts of the GUI. This is in preparation of adding many more track properties in future releases, allowing the user to hide parts they don\'t use all that often.
* MKVToolNix GUI: multiplexer: if the option \"use legacy font MIME types\" is enabled in the preferences, the new command line option `--enable-legacy-font-mime-types` will be passed to `mkvmerge` in order to have it remap the MIME types of existing attachments, too. Bug fixes:
* all: IETF BCP 47/RFC 5646 language tags: variants aren\'t validated wrt. to prefixes anymore as BCP 47 doesn\'t actually pose restrictions on them, saying only that prefixes \"are suitable sequences\" for use with the variants. What is now verified, though, is that no variant is used multiple times within the same language tag.
* build system & MKVToolNix GUI: fixed detecting the presence of & the compilation with the multimedia module of Qt version 6.2.0 and newer.
* MKVToolNix GUI: job queue: fixed compiling in the audio player code for the the \"play audio\" end-of-job action.
* MKVToolNix GUI: multiplexer: recognizing added XML chapter, segment info or chapter files required the XML declaration & root node (e.g. ` … ` for chapters) be located within the first 1 KB, which wasn\'t enough for files that contain a lot of comments at the start like the included `example-chapters-2.xml`. The detection range was extended to 10 KB. Build system changes:
* The bundled `fmt` library was updated to v8.1.1.
* The bundled `nlohmann-json` library was updated to v3.10.5.
* The bundled `pugixml` library was updated to v1.12.1.
* Sun Mar 13 2022 Luigi Baldoni - Update to version 66.0.0 New features and enhancements:
* mkvpropedit: added a new option `--chapter-charset` allowing the user to specify the character set to use when reading the following chapter file.
* MKVToolNix GUI: each language shortcut can now be associated with an optional track name that is set along with the language when the shortcut is used. Bug fixes:
* mkvmerge: Ogg/OGM reader: mkvmerge will no longer abort with an exception when it encounters Vorbis comments that contain data that isn\'t valid UTF-8.
* MKVToolNix GUI: multiplexer: fixed several issues with the tab order of elements in the \"properties\" pane and the \"output\" tab. Also fixed the language display widgets (e.g. \"track language\" in the \"properties\" pane) never receiving tab focus.
* MKVToolNix GUI: multiplexer: the chapter name template will now be passed to `mkvmerge` if a chapter file is selected on the \"output\" tab.
* Sun Feb 06 2022 Luigi Baldoni - Update to version 65.0.0 New features and enhancements:
* mkvmerge: the options `--default-track` and `--forced-track` have been renamed to `--default-track-flag` and `--forced-display-flag` respectively for improved consistency with other option names & the wording used in the GUI. However, the old names will be supported and recognized indefinitely. What will remain unchanged is the property names for those flags in mkvmerge\'s identification output. Existing third-party programs will continue working as they are.
* mkvmerge: added a new option `--track-enabled-flag` to set or unset the \"track enabled\" track header flag.
* mkvmerge: MP4 reader: `mkvmerge` will now evaluate the `flags` field of the track header atom (`tkhd`) and set the track\'s \"enabled\" flag accordingly.
* MKVToolNix GUI: multiplexer: added support for the \"track enabled\" track header flag.
* MKVToolNix GUI: multiplexer, header editor: added several menu entries & keyboard shortcuts for toggling various track flags of the currently selected tracks, e.g. `Ctrl+Alt+F, D` (that\'s `Ctrl` and `Alt` with `F` simultaneously followed by `D` without any other key pressed) for toggling the \"default track\" flag.
* MKVToolNix GUI: multiplexer, header editor: added menu entries & keyboard shortcuts for setting the language of the currently selected tracks to one from a configurable list of languages. The shortcuts used are `Ctrl+Alt+A, 1` through `Ctrl+Alt+A, 0` for the first ten entries of that list (that\'s `Ctrl` and `Alt` with `A` simultaneously followed by a digit without any other key pressed).
* MKVToolNix GUI: chapter editor: if the user enters commas in start or end timestamps they will automatically be changed to points as the decimal separator, allowing for easier copy & paste from other programs/sources.
* MKVToolNix: header editor: the selected track or attached file can now be moved up & down with the keyboard shortcuts `Ctrl+Up` & `Ctrl+Down` respectively. Bug fixes:
* mkvmerge: Matroska reader: DVB subtitle tracks with a codec private data size of more than five bytes are accepted now, too.
* Mon Jan 10 2022 Guillaume GARDET - Update _constraints to cover all architectures, not only ppc64
* Mon Dec 27 2021 Luigi Baldoni - Update to version 64.0.0 New features and enhancements:
* MKVToolNix GUI: language dialog: when the user switches between the two edit modes, the mode\'s corresponding first control is automatically focussed. Bug fixes:
* all: language lists: the entries for \"Ancient Greek (to 1453)\" and \"Modern Greek (1453-)\" have been renamed to \"Greek (ancient, -1453)\" and \"Greek (modern, 1453-)\" respectively in order to be easier to find.
* mkvmerge: VobSub reader: files containing `id: --` lines to indicate that the track language isn\'t known were rejected by `mkvmerge`. Now they\'re accepted, and `und` (undetermined) is used as the language.
* MKVToolNix GUI: chapter editor: the \"Save to Matroska or WebM file\" function was using the wrong standard file dialog (the \"open file\" one instead of \"save\"), leading to confusing button names.
* MKVToolNix GUI: high DPI scaling: fixed the icons in the tool selector having the wrong size for scaling factors other than 100% or 200%. Build system changes:
* The bundled `fmt` library was updated to v8.0.1.
* The bundled `nlohmann-json` library was updated to v3.9.1.
* The bundled `pugixml` library was updated to v1.11 revision 6a76cac.
* The bundled `utf8-cpp` library was updated to v3.2 revision b85efd6.
* Sun Nov 14 2021 Luigi Baldoni - Update to version 63.0.0 New features and enhancements:
* mkvmerge: AC-3 parser: E-AC-3 with BSID values > 10 and ≤ 15 are recognized now, too.
* mkvmerge: when using language codes for track selection (e.g. `-a und,en`) all tracks that do not have a language property (due to their container not providing one, e.g. AVIs) will be treated as if they did have one set to `und` (\"undetermined\") as that is the language the track will have in the Matroska file anyway. Before this change it wasn\'t possible to match such tracks via language codes.
* MKVToolNix GUI: the spinner in the bottom right corner will now be hidden when no jobs are currently running.
* MKVToolNix GUI: header editor: a new column has been added to the tree view showing the status of the \"track enabled\" flag. The information is also shown on the track overview page on the right.
* MKVToolNix GUI: header editor: users can now reorder tracks by dragging & dropping. Bug fixes:
* mkvmerge: AVI reader: fixed reading AVI files that contain `vprp` video properties header chunks; reading aborted too early.
* Sun Oct 10 2021 Luigi Baldoni - Update to version 62.0.0 New features and enhancements:
* all: IETF BCP 47/TFC 5646 language tags: all ISO 639 languages are now available, even the ones that aren\'t of types \"Constructed\", \"Living\" or \"Special\".
* mkvmerge, mkvpropedit: chapters: both programs will now write elements set to their default value, too (e.g. the legacy language element if it\'s set to `eng`). This is done to be more consistent with how MKVToolNix GUI writes chapters.
* MKVToolNix GUI: multiplexer: when adding new files as attachments the GUI checks if there are other attachments with the same name. If so, the GUI would ask whether to skip the affected files or add them anyway. There\'s now an option in the preferences to always skip such files, and it\'s enabled by default.
* MKVToolNix GUI: chapter editor: removed the support for explicitly setting the legacy country elements. Instead the legacy country elements are derived from the region parts of the IETF BCP 47 languages. Bug fixes:
* mkvmerge: fixed a crash when splitting by chapters is enabled but there are no chapters at all.
* mkvmerge: the error message when trying to split by a chapter number that doesn\'t exist contained the wrong number of chapters that actually do exist.
* mkvmerge: AVC ES parser: fixed mkvmerge aborting due to uncaught exception when encountering bad SPS data.
* mkvmerge: AVC/H.264 parser: re-added the hack `--engage all_i_slices_are_key_frames` which was accidentally removed in release v61.
* mkvmerge: AVI reader: fixed a crash trying to allocate too big of a memory chunk due to an integer overflows in check conditions.
* mkvmerge: HEVC ES parser: fixed another issue with frame type recognition. Certain frames were marked as B frames/discardable on the container level even though they could be reference pictures. Now only SLNR pictures (sub-layer non-reference) are marked that way.
* mkvmerge: HEVC ES reader: improved file content detection for HEVC ES files with wrong file name extensions (e.g. `.mkv`), which fixes them being mis-detected as something else, e.g. DTS.
* mkvmerge: HEVC ES parser: \"end of sequence\" NALUs are kept now, and no superfluous flushing will be done when one is found. This prevents splitting NALUs into two different Matroska blocks when they should really be part of a single one, also causing problems with erroneous timestamps. Mostly affects DoVi NALUs.
* mkvmerge: Matroska reader, TrueHD: mkvmerge will now probe much more TrueHD frames trying to find the first sync frame. This fixes track detection in situations when a TrueHD doesn\'t start with a sync frame, e.g. when the source file\'s the result of splitting between sync frames.
* mkvmerge, MKVToolNix GUI\'s chapter editor: IETF BCP 47/RFC 5646 language tags: when reading chapters from MPLS playlist files, the `ChapLanguageIETF` element will now be set to the configured default chapter language, not just the legacy `ChapterLanguage` element.
* mkvmerge, mkvpropedit, MKVToolNix GUI\'s chapter editor: IETF BCP 47 elements will now always be created before writing chapters unless IETF BCP 47 elements are disabled.
* mkvmerge, mkvpropedit, MKVToolNix GUI\'s chapter editor: when a chapter display element contains legacy language & country elements but no IETF BCP 47 elements and IETF BCP 47 elements aren\'t disabled, the IETF BCP 47 elements created will contain the region from the legacy element.
* mkvmerge, mkvpropedit, MKVToolNix GUI\'s chapter editor: Legacy country elements are now created when IETF BCP 47 elements are present & contain a region code allowed in legacy country elements. Build system changes:
* The `tools` sub-directory is now always built. The corresponding `configure` option `--with-tools` has been removed. The `install` target still doesn\'t install them, though.- Add tools subpackage
* Mon Aug 30 2021 Luigi Baldoni - Update to version 61.0.0 New features and enhancements:
* all: IETF BCP 47/RFC 5646 language tags: implemented support for officially registered IANA language tag extensions.
* mkvmerge: track selection: when using language tags for selecting which tracks to keep, mkvmerge will now use component-based language tag matching instead of comparing them verbatim. This means that only those components (language, region etc.) the user specified will be required to exist and be equal. For example, if a file contains three subtitle tracks with languages `es` (generic Spanish), `es-MX` (Spanish as spoken in Mexico) and `es-ES` (Spanish as spoken in Spain), the user can use `--stracks es` to match all three tracks or be more specific with e.g. `--stracks es-MX` which would only match one track. Similarly inverting the selection with e.g. `--stracks !es` would get rid of all three tracks, not just the one for the generic Spanish.
* MKVToolNix GUI: multiplexer: deriving track languages from file names: the GUI can now detect full BCP 47/RFC 5646 language tags in file names.
* MKVToolNix GUI: multiplexer: deriving track languages from file names: the default list of boundary characters now includes `-`.
* MKVToolNix GUI: multiplexer: the GUI now defaults to the \"lower\" process priority setting for new installations in order to leave more room for other applications, especially interactive ones. Up to and including v59 the default was the \"normal\" process priority. v60 changed that to \"lowest\", which turned out to be much slower on Windows for no real gain over \"lower\". The setting will be auto-corrected by the GUI if the settings file were saved last with a version between v60.0.0.0 & v60.0.0.17 & \"lowest\" & it is still set to \"lowest\".
* HEVC dumper development tool: the tool has been renamed to `xvc_dump` and extended to be able to dump AVC/H.264 bitstreams, too. It now also detects the type of bitstream framing (ISO 14496-15 vs. ITU-T H.264/H.265 Annex B). Bug fixes:
* all: IETF BCP 47/RFC 5646 language tags: fixed a corner case of wrongfully allowing scripts/variants not listed in any of the entries in the prefix list when the prefix list contains prefixes restricting scripts/variants and a prefix solely with the language at the same time (example: the variant `ekavsk` with its prefixes `sr`, `sr-Cyrl` and `sr-Latn` where e.g. `sr-ekavsk` and `sr-Cyrl-ekavsk` should be allowed but not `sr-Bali-ekavsk`).
* mkvmerge: HEVC/H.265: the frame type of B frames was often wrongfully signalled as P frames instead, both with `BlockGroup` (missing second references) and `SimpleBlock` (\"discardable\" flag not set) elements.
* mkvmerge: SSA/ASS packetizer: the frame numbers will now be re-calculated when appending SSA/ASS tracks so that frame numbers of appended tracks are always strictly higher than frame numbers of the track they\'re appended to.
* mkvmerge, MKVToolNix GUI\'s chapter editor: BCP 47/RFC 5646 language tags: when BCP 47 language tags are used with a language code that isn\'t part of ISO 639-2, the programs will now write a legacy language element set to `und` (\"undetermined\") instead of not writing such an element at all or writing one with an invalid code.
* mkvmerge, MKVToolNix GUI\'s chapter editor: BCP 47/RFC 5646 language tags: the programs will ensure that the legacy and IETF language elements written will be unique within the scope of the same \"chapter display\" element.
* mkvinfo, MKVToolNix GUI\'s info tool: in summary mode the frame type was reported wrong for `BlockGroup` elements in which the `ReferenceBlock` elements were located behind the `Block` element. Build system changes:
* all: `std::codecvt_utf8` is now used instead of Boost\'s `utf8_codecvt_facet`. The bundled copy the latter in `lib/boost` has therefore been removed.- Drop mkvtoolnix-use-system-boost.patch (no longer necessary)
* Sat Jul 31 2021 Luigi Baldoni - Update to version 60.0.0 New features and enhancements:
* all: IETF BCP 47/RFC 5646 language tags: added support for language families from ISO 639-5 that aren\'t part of 639-2.
* all: IETF BCP 47/RFC 5646 language tags: implemented support for Alpha 2 country codes of the \"user-defined\" category: `AA`, `QM`–`QZ`, `XA`–`XZ` and `ZZ`.
* all: IETF BCP 47/RFC 5646 language tags: updated the various lists of valid subtags from the official specs.
* MKVToolNix GUI: multiplexer: pressing the keyboard shortcut for the track\'s \"Language\" label (Alt+L for English) will now open the language dialog.
* MKVToolNix GUI: multiplexer: added an option in the preferences for turning off the colored boxes indicating which file each track belongs to. Bug fixes:
* all: IETF BCP 47/RFC 5646 language tags: fixed validating extended language & variant subtags against their allowed prefixes (e.g. a valid tag with a country code as in `de-CH-1996` is recognized as valid while two generally known variants that aren\'t allowed together as in `de-1901-1996` is recognized as invalid).
* all: IETF BCP 47/RFC 5646 language tags: when looking up a language for a two- or three-letter code, the programs will no longer compare that code with language names as that was unintended, ambiguous (e.g. the code \"Ga\" could be interpreted as the 639-2 alpha-2 code for \"Irish\" or as the name of the language called \"Ga\") and only worked with languages whose name was at most three letters long.
* mkvmerge: HEVC/H.265: appending Matroska files with HEVC tracks might lead to the loss of the first couple of frames from each of the second and all following files.
* mkvmerge, mkvextract: HEVC/H.265 parser: fixed the programs aborting when parsing VPS or SPS NALUs with invalid content due to unhandled exceptions.
* MKVToolNix GUI: multiplexer: when the option \"use legacy MIME types for font attachments\" is enabled, the GUI will now use `application/x-truetype-font` for font collection files.
* MKVToolNix GUI: multiplexer: when adding multiple files at once, the GUI will sort file names with numbers the way a human would expect it to. For example, `1.mp4`, `9.aac`, `10.srt`, `11.srt` are now sorted exactly that order instead of `1.mp4`, `10.srt`, `11.srt`, `9.aac`.
* MKVToolNix GUI: header editor: the header editor will now honor the \"use legacy MIME types when adding font attachments\" setting when adding new attachments.
* Sat Jul 10 2021 Luigi Baldoni - Update to version 59.0.0 New features and enhancements:
* mkvmerge: WebVTT parser: the parser now follows the specs\' rules for parsing timestamps more closely by being more lenient: it allows arbitrary number of spaces & tabs at the start of the line & around the arrow; it allows any number of digits for the hours.
* MKVToolNix GUI: multiplexer: when adding a Blu-ray playlist without scanning for other playlists the GUI will now look for disc library information & let the user select which one to use if there\'s more than one entry.
* MKVToolNix GUI: multiplexer: added an option for sorting files & tracks by track types when adding them to multiplex settings. The order is: video first followed by audio, subtitles and other types. Files & tracks can still be reordered manually later. The option is enabled by default & can be found in the preferences → \"Multiplexer\" page → \"Adding files\" section.
* MKVToolNix GUI: multiplexer: added an option for recognizing file name sequences such as `movie.001.mp4`, `movie.002.mp4`, `movie.003.mp4` when adding multiple files at once. If a sequence is detected, the only first file will be added while the second and following file names will be appended to the first one. The option is enabled by default & can be found in the preferences → \"Multiplexer\" page → \"Adding files\" section.
* MKVToolNix GUI: multiplexer: added small colored boxes for each file & track in order to indicate from which file each track is read. The colors used can be configured in the preferences → \"Multiplexer\" page → \"File & track colors\" section. Bug fixes:
* build system: fixed compilation with fmt v8. Fixes #3151.
* mkvmerge: SRT subtitle reader: characters that aren\'t valid according to the assumed encoding of the file will now be replaced by the Unicode \"Replacement Character\" U+FFFD instead of keeping the invalid characters, potentially violating the Matroska specs.
* mkvmerge: WebVTT parser: the parser now accepts timestamps with hours larger than 99.
* mkvextract: TTA extraction, only on Windows: fixed removing the temporary file created during extraction.
* mkvmerge, mkvpropedit, MKVToolNix GUI\'s multiplexer & header editor: MIME type detection is now done using Qt instead of the `magic` library. The main impact is the MIME types of TrueType & OpenType fonts are now detected correctly.
* MKVToolNix GUI: multiplexer: when adding files to the multiplexer by running the GUI\'s executable with file names as command line arguments, the source directory will be remembered as the \"last open directory\" again, causing subsequent uses of the \"open file\" dialog to start in the same directory.
* MKVToolNix GUI: multiplexer: the \"default track flag\" column in the track list was missing its icons. Additionally it contained text even for things that aren\'t regular tracks and therefore do not actually have that flag (e.g. chapters or tags).
* MKVToolNix GUI: multiplexer: the default for the dialog asking the user what to do with dragged & dropped files if they\'ve never seen the dialog is back to adding the files to the current multiplex settings instead of \"add as additional parts\" which was an unintentional default.
* MKVToolNix GUI: multiplexer: the \"show command line\" dialog will now always use backward slashes for the \"Windows (cmd.exe)\" mode and forward slashes for the \"Linux/Unix shells\" mode, regardless of the operating system it\'s currently running on. Build system changes:
* The Qt library is now required for building all applications, even the command-line ones, as they use Qt\'s MIME type detection capabilities. In turn this means that you cannot disable the Qt usage anymore; either Qt5 or Qt 6 is required. You can still chose not to build MKVToolNix GUI, though. A new option has been added to `configure` for this purpose: `--disable-gui`.
* The `gmp` library is now required.
* The `magic` library is not used anymore.
* The `PCRE2` & `JPCRE2` libraries are not used anymore. The bundled version of `JPCRE2` was removed.
* Boost\'s \"rational\" library is not used anymore.
* `configure`: the option `--enable-appimage` has been removed. The location of the relevant directories within an AppImage is now detected automatically.
* The bundled `fmt` library was updated to v8.0.0.- Use system version of utfcpp
* Sun Jun 13 2021 Luigi Baldoni - Update to version 58.0.0 New features and enhancements:
* mkvmerge, MKVToolNix GUI\'s multiplexer: the handling of the \"default track\" flag has been changed to match the recent changes to the Matroska specifications. The new semantics are that if it is set, it is supposed to signal to the player that this track is eligible for being played by default, potentially taking other factors such as user preferences regarding languages into account. This implies that more than one track of each type can have this flag set. For example, a Blu-ray disc with three audio tracks might have the main audio in both English and Japanese, whereas the third audio track contains the director\'s comments. In such a case the first two tracks should have the \"default track\" flag set, the third one shouldn\'t. Earlier `mkvmerge` was enforcing that only one track of each type could have the flag set. This restriction has been removed, both in `mkvmerge` and in the GUI\'s multiplexer. `mkvpropedit` and the GUI\'s header editor are unaffected as they\'ve always allowed to set the flag on as many tracks as the user wanted.
* mkvmerge: AVC/H.264 & HEVC/H.265 identification: added the stream\'s pixel dimensions (AVC only; were present for HEVC already) & default duration.
* mkvmerge, mkvextract: HEVC/H.265: added support for reading single-layer Dolby Vision from Annex B type bitstreams (elementary streams, MPEG transport streams).
* mkvinfo: the option `-X`/`--full-hexdump` now affects all binary elements, not just the frame data in `SimpleBlock` and `BlockGroup` elements.
* MKVToolNix GUI: multiplexer: the \"delay\" and \"sync\" options can now be used for chapters in source files, too.
* MKVToolNix GUI: when moving list entries up & down with the optional buttons or the keyboard shortcuts (instead of using drag & drop), the GUI ensures that the top-most selected entry remains visible after the move.
* MKVToolNix GUI: added an option in the preference to use legacy MIME types for font attachments instead of the current standard ones (e.g. \'application/x-truetype-font\' instead of \'font/sfnt\' and \'font/ttf\'). Bug fixes:
* build system: fixed filtering out optimization options when compiling the file `iso639_language_list.cpp` (before only numeric optimization levels were filtered out and only if it wasn\'t the last option in the list of flags).
* build system: when libmagic was detected via `pkg-config`, MKVToolNix was actually compiled without support for libmagic due to a preprocessor symbol not being defined.
* mkvmerge: MP4 reader: fixed an issue with timestamps overflowing when the file\'s or the track\'s time scale is large.
* mkvmerge, mkvextract: fixed key frame handling for `BlockGroup` elements with a forward reference but no backward references.
* mkvmerge, mkvpropedit, MKVToolNix GUI\'s chapter editor: the programs will no longer omit writing mandatory elements set to their default value if other elements of the same type are present in the same master. This affects mostly the \"chapter language\" element which may occur multiple times within the same \"chapter display\" master. If it does occur multiple times and one of them is set to \"English\" (which is that element\'s default value), that element will now be written, too.
* mkvmerge, mkvpropedit, MKVToolNix GUI\'s chapter editor: when parsing chapter files IETF & legacy language elements as well as legacy country elements will now be properly generated depending on which exist already, especially when there\'s more than one language and/or country element in a \"chapter display\" element.
* mkvmerge, mkvpropedit, MKVToolNix GUI\'s chapter editor: fixed reading OGM-style chapter files with timestamps that don\'t have exactly three decimal places. Any number of decimal places between one and nine is now supported for nanosecond precision.
* MKVToolNix GUI: chapter editor: added/fixed support for \"chapter display\" elements with multiple languages or countries. Build system changes:
* Qt 6: added support for building with Qt 6. `configure` will look for Qt 6 first and only continue looking for Qt 5 if Qt 6 isn\'t found or disabled via `--disable-qt6`. Qt 6 detection works by first looking for the `qmake6` binary. Its location can be specified with the `--with-qmake6=…` option. All other Qt 6 related facts (such as compiler & linker flags or the position of the other required tools such as `lconvert`, `moc`, `rcc` and `uic`) will be derived from the output generated by `qmake6`. Note that at this point Qt 6 is not yet supported for the cross-compilation build to Windows, nor is a static Qt 6 build supported yet. Note that the command line options `--enable-static-qt`, `--with-qt-pkg-config-modules` and `--without-qt-pkg-config` only apply to the Qt 5 and have no effect on Qt 6.
* Qt 5: the options for specifying the position of the tools (`--with-moc=…`,`--with-rcc=…` and `--with-uic=…`) have been removed. Their position will now be derived from the output generated by `qmake`.
* `configure`: completely disabling the GUI now requires passing both `--disable-qt6` and `--disable-qt` options.
* Boost\'s multi-precision library is now required.
* Boost v1.66 or newer is now required.
* Sat May 22 2021 Luigi Baldoni - Up date to version 57.0.0 New features and enhancements:
* mkvmerge: MP4 reader: added support for reading Dolby Vision from MP4 files (FourCCs `dvh1` and `dvhe`; configuration records `dvcC`, `dvvC` and `hvcE` will be converted into block addition mappings).
* mkvmerge: SRT subtitles: mkvmerge now accepts empty text files with the extension `.srt` as SRT subtitle files, enabling the creation of empty SRT tracks.
* mkvmerge, mkvextract: HEVC/H.265: access unit delimiter NALUs will no longer be discarded, neither during muxing nor during extraction.
* MKVToolNix GUI: preferences: switched the order & wording of controls in the \"enabling items\" panel to make it clearer that certain controls define exceptions. Bug fixes:
* mkvmerge: HEVC/H.265 parser: several NALU types, notably the Dolby Vision-specific NALUs (\"unspecified 62\" and \"unspecified 63\") and suffix SEI NALUs, are now stored with the frame they belong to instead of with the next frame.
* mkvmerge: HEVC/H.265 packetizer: fixed setting the track\'s default duration when reading HEVC/H.265 from Matroska files that don\'t have a default duration set.
* mkvmerge: HEVC/H.265 packetizer: fixed the calculation of the duration of frames so that `SimpleBlock` elements can be used again instead of `BlockGroups` with `BlockDuration` elements.
* mkvmerge, mkvextract: HEVC/H.265 parser: fixed issues with ordering & duplication of certain NALUs (parameter set & prefix SEI NALUs).
* MKVToolNix GUI: multiplexer: when dragging & dropping files to the multiplexer, the source directory will be remembered as the \"last open directory\" again, causing subsequent uses of the \"open file\" dialog to start in the same directory.
* mkvinfo: fixed the position of frames in block groups containing \"block duration\" elements in summary mode (e.g. for subtitle tracks). Build system changes:
* `configure` will now try to detect `libmagic` via `pkg-config` and fall back to including & linking directly if it cannot be found via `pkg-config`.
* Fri Apr 09 2021 aloisioAATTgmx.com- Update to version version 56.1.0 New features and enhancements:
* mkvmerge: AAC: added support for LOAS/LATM files with channel configuration indexes 9–21 (e.g. channel count 22.2 for index 13) according to Rec. ITU-R BS.1196-7 & ISO/IEC 23008-3:2019. Bug fixes:
* mkvmerge: HEVC/H.265 parser: fixed invalid memory access that could happen when reading certain types of HEVC data (e.g. with changing parameter sets mid-stream) from certain containers (e.g. Matroska). This bug was introduced in release 56.0.0.
* mkvextract: AAC: mkvextract will now abort with an useful error message when the user tries to extract a track whose \'audio-specific config\' element in `CodecPrivate` signals a number of channels of 7 or greater than 8 as that isn\'t supported by the ADTS format. Build system changes:
* configure: the `--enable-ubsan` option hasn\'t actually enabled anything since release 39.0.0.
* Mon Apr 05 2021 Luigi Baldoni - Update to version 56.0.0 New features and enhancements:
* mkvmerge, mkvpropedit: tags: the programs will no longer write tag elements that are mandatory and set to their default value (e.g. \"tag language\" set to `und` = undetermined).
* mkvmerge, mkvpropedit, MKVToolNix GUI chapter editor: chapters: the programs will no longer write chapter elements that are mandatory and set to their default value (e.g. \"chapter language\" set to `eng` = English or \"Chapter flag enabled\" = 1).
* mkvextract: chapters: mkvextract will no longer add a `ChapterLanguage` element set to `eng` to the generated XML content if the source file doesn\'t contain such an element.
* MKVToolNix GUI: multiplexer: when using the \"tab widget below the files & tracks\" layout option for the track properties the elements in the \"general options\" tab will use six rows à four columns instead of twelve rows à two columns, greatly reducing the required height. Bug fixes:
* mkvmerge: AAC reader: fixed mkvmerge aborting to read AAC files bigger than 2 GB with a message about not being able to allocate memory.
* mkvmerge: chapters: `ChapLanguageIETF` elements were still created when the option `--disable-language-ietf` was given after an option leading to the creation of chapters. Now the position doesn\'t matter anymore.
* mkvmerge: chapters: when the option `--disable-language-ietf` is used, `ChapLanguageIETF` elements won\'t be written even when sources are read (Matroska files or XML chapters files) that do contain those elements.
* mkvmerge: tags: when the option `--disable-language-ietf` is used, `TagLanguageIETF` elements won\'t be written.
* mkvmerge: tags: mkvmerge will no longer write language elements for the track statistics tags it creates, making the effective language \"undetermined\" due to `und` being the default value for the legacy tag language element.
* mkvmerge: tags: the XML tag parser will now validate all `` children of `` elements, not just the first for each ``.
* mkvmerge: tags: the XML tag parser now uses the spec-compliant `und` (\"undetermined\") as the default language for `` tags instead of `eng`.
* mkvmerge, mkvpropedit: tags: mkvmerge will no longer set the \"target type\" for track statistics tags (earlier it used `MOVIE`). The \"target type value\" will still be set to `50`.
* mkvmerge, mkvextract: HEVC/H.265: both programs will now normalize the placement of VPS, SPS and PPS NALUs. Each key frame is prefixed with exactly one copy of the currently active parameter sets. This fixes certain classes of bugs related to splitting/appending.
* mkvinfo: when compiled with newer versions of the `fmt` library, certain numbers were not output correctly (e.g. a track\'s audio sampling frequency of 48000 might be output as 48).
* MKVToolNix GUI: multiplexer: deriving the track language from the file name will match languages case insensitively again (like versions prior to v55).
* MKVToolNix GUI: multiplexer: under certain circumstances keyboard shortcuts such as `Ctrl+W` for closing the active tab or `Ctrl+R` for starting to multiplex ceased to work until the user did certain other things (such as switching to a different tool & back to the multiplexer or opening the multiplexer menu). This started with v54.
* MKVToolNix GUI: chapter editor: the editor will no longer create empty `ChapterCountry` elements when adding a chapter name with no default country selected in the preferences. Build system changes:
* The bundled `fmt` library was updated to v7.1.3.
* Sat Mar 06 2021 Luigi Baldoni - Update to version 55.0.0 Bug fixes:
* MKVToolNix GUI: multiplexer: the user can now configure what to do when using the \"Add source files\" button independently of the setting for what happens when files are dragged & dropped onto the GUI. The same options are available, but they\'re distinct settings, allowing for different use cases.
* MKVToolNix GUI: multiplexer: deriving the track language from file names doesn\'t use one big regular expression of all enabled languages anymore. Instead, the file name is split into parts on a list of characters (such as `.` or `(` and `)`; configurable in the preferences). This prevents the regular expression becoming too big for the regular expression library to handle when many languages are enabled.
* MKVToolNix GUI: preferences: the language lists for \"deriving track languages\" and \"enabling items by language\" always included all the ISO 639-3 languages, even if those weren\'t enabled in the \"often-used languages\" pane. Other changes:
* mkvmerge, MKVToolNix GUI multiplexer: the functionality for changing the length of the NALU \"size\" field for AVC/H.264 and HEVC/H.265 tracks has been removed. The corresponding command-line option will continue to be recognized by mkvmerge as not to break existing third-party applications, but it won\'t actually do anything.
* Fri Feb 26 2021 Luigi Baldoni - Update to version 54.0.0 New features and enhancements:
* mkvmerge: added support for using ISO 639-3 language codes in IETF BF47 language tags.
* mkvmerge: AC-3 parser: added support for byte-swapped AC-3 data.
* mkvmerge: Matroska reader: for audio tracks that have the bit depth track header set mkvmerge will now keep that header even for codecs that don\'t require it for decoding.
* mkvmerge: MPEG transport stream reader, PCM audio tracks: mkvmerge will now re-order the channels for 5.1, 7.0 and 7.1 channel tracks from the Blu-ray layout to the WAVEFORMATEXTENSIBLE layout expected in Matroska.
* mkvmerge, mkvinfo, mkvpropedit, MKVToolNix GUI: added support for the following new track header elements: \"hearing impaired\" flag, \"visual impaired\" flag, \"text descriptions\" flag, \"original\" flag, \"commentary\" flag.
* MKVToolNix GUI: added support for using ISO 639-3 language codes in IETF BF47 language tags. As there are several thousand of them, they\'re deactivated by default and must be activated in the preferences (\"GUI\" → \"Often used selections\" → \"Languages\").
* MKVToolNix GUI: multiplexer: when adding Blu-rays the user can select multiple playlists to add simultaneously in the \"select playlist to add\" dialog.
* MKVToolNix GUI: multiplexer: the file name extensions \"eb3\" and \"ec3\" were added for Dolby Digital Plus & \"mpl\" for Dolby TrueHD in the file dialogs.
* MKVToolNix GUI: multiplexer: when adding multiple files the dialog asking the user what to do with them has gained a new checkbox. If enabled, all files containing at least one video track will always be placed in newly created multiplex setting.
* MKVToolNix GUI: multiplexer: added a menu entry in the \"Multiplexer\" for adding all files that are currently in the clipboard. Bug fixes:
* mkvextract: AAC: fixed wrong channel mask field in the ADTS headers for 7.1 channel layouts.
* mkvextract: h.265/HEVC extraction: if the first frame starts with the parameter sets (SPS, PPS & VPS), the ones from CodecPrivate aren\'t written and the ones from the first frame are kept.
* mkvmerge: fixed the calculation of chapter timestamps read from NTSC DVDs.
* MKVToolNix GUI: IETF BCP 47 language widget: the language combo box will now always contain the language code the user enters in the free-form field, even if it isn\'t in the list of often-used languages the user configured in the preferences.
* MKVToolNix GUI: multiplexer: when browsing for the destination file name the default directory is now chosen according to the preferences regarding how the destination file name should be formed. For example, if the policy is set to \"fixed output directory\" then that output directory will be the one initially set when the directory selection dialog is opened.
* MKVToolNix GUI: multiplexer: fixed the removal of appended source files if the \"delete source files\" end-of-job action is enabled.
* MKVToolNix GUI: chapter editor: when importing chapters from DVDs the IETF BCP 47 language elements will be set, too, not just the legacy language elements. Build system changes:
* libEBML v1.4.2 and libMatroska v1.6.3 are now required. The optional, bundled copies of both libraries have been updated to those versions. This bump in requirements fixes several heap overflow bugs in libEBML.
* MKVToolNix is now using the C++17 library feature \"file system library\" instead of Boost\'s \"file system\" and \"system\" libraries. For the GNU Compiler Collection (gcc) libstdc++ this means v8 or newer is required; for clang\'s libc++ it means v7 or newer.
* Sat Jan 30 2021 Luigi Baldoni - Update to version 53.0.0 New features and enhancements:
* mkvmerge: AVI reader: added support for reading the video aspect ratio from the video properties header (`vprp` chunk) if present and setting the display dimensions accordingly.
* mkvmerge: MP4 reader: for h.264/AVC tracks that don\'t have an `AVCConfigurationBox` (`avcC` atom) in their sample description (`stsd`) atom or whose `avcC` atom contains no content `mkvmerge` will now re-derive the `AVCConfigurationBox` from the bitstream.
* mkvextract: mkvextract will now check if any of the destination file names is the same as the source file name and abort with an error if that\'s the case.
* MKVToolNix GUI: when querying the user for a file name for saving things (e.g. multiplexer settings or an attachment in the header editor), the automatically suggested file name will now be based on the situation-specific file names (e.g. the destination file name for multiplexer settings or the attachment\'s name when saving an attachment in the header editor) instead of the directory\'s name.
* MKVToolNix GUI: multiplexer: when deriving track languages from file names the GUI will now select the right-most match instead of the left-most one. For example, \"La.vie.en.rose.(fr).srt\" will now be detected as French (fr) instead of English (en).
* MKVToolNix GUI: preferences: the items in the \"pre-defined …\" lists can now be renamed by double-clicking with the mouse or pressing the F2 key. Bug fixes:
* mkvmerge: stretching chapter timestamps with `--chapter-sync` now works correctly with floating point values including fractions of floating point numbers (e.g. `12.3/45.67`). The tooltips in the GUI have been adjusted accordingly.
* mkvmerge: MPEG 1/2 video handling: the \"default duration\" header field was often half the value it actually should be, resulting in all video frames having an explicit block duration with the correct value.
* mkvmerge: MPEG 1/2 video handling: the data stored in `Codec private` and `Codec state` doesn\'t contain extensions other than sequence & sequence display extensions anymore.
* mkvmerge: tag handling: when remuxing a Matroska file with the `--no-track-tags`, existing `SOURCE_ID` track tags are now skipped, too.
* MKVToolNix GUI: multiplexer: the drop-down boxes with pre-defined track names now follow the order set in the preferences instead of sorting the entries alphabetically.
* Tue Jan 05 2021 aloisioAATTgmx.com- Update to version 52.0.0 New features and enhancements:
* MKVToolNix GUI: job queue: the maximum number of jobs to run concurrently can now be increased in the preferences. The default remains at 1.
* MKVToolNix GUI: the GUI will now add a context-specific default extension to file names selected for saving on platforms that don\'t add one itself (e.g. GNOME). For example, when saving multiplexer settings the extension `.mtxcfg` will be added.
* MKVToolNix GUI: added an option to the preferences for the window to stay on top of other windows. Bug fixes:
* mkvextract: h.265/HEVC extraction: the code for skipping extraction of prefix SEI NALUs in the first frame was skipping two bytes too few, resulting in broken processing of all following bytes.
* libEBML: the optional, bundled version of libEBML was updated to v1.4.1. Build system changes:
* libEBML v1.4.1 is now required due to a bug in libEBML that caused pointers to just-freed memory being returned to the caller under certain invalid data constellations, causing use-after-free errors in all of MKVToolNix\'s programs.
* Sun Oct 04 2020 Luigi Baldoni - Update to version 51.0.0 New features and enhancements:
* mkvmerge, mkvpropedit, MKVToolNix GUI: IETF BCP 47 language tags: added missing support for UN M.49 regions for which there are no corresponding ISO 3166 alpha codes. This enables language tags such as `es-419` = Spanish in Latin America and the Caribbean.
* MKVToolNix GUI: IETF BCP 47 language tags: the text in the widget displaying the current language & the corresponding edit button is now displayed like a link (depending on the theme: different color & underlined), making it clearer that not just the edit button can be clicked but the text, too. Bug fixes:
* mkvmerge: AV1 parser: fixed mkvmerge crashing after uncaught exceptions due to certain data conditions. Found by fuzzying.
* mkvmerge: AV1 packetizer: the duration of frames wasn\'t set properly. When appending AV1 IVF or OBU files this meant that the last frame of the Nth file and the first frame of file N+1 had the same timestamp.
* mkvmerge: DTS reader: fixed handling of buffers with an odd length when byte-swapped DTS is detected so that mkvmerge doesn\'t abort with a failed assertion. Found by fuzzying.
* mkvmerge: h.264/AVC and h.265/HEVC elementary stream readers: mkvmerge will no longer claim to recognize data that looks like AVC or HEVC but with invalid video width/height values as that lead to failed assertions in libEBML later. Found by fuzzying.
* mkvmerge: h.265/HEVC parser: fixed mkvmerge aborting after uncaught exceptions due to certain data constellations found by fuzzying.
* mkvmerge: IVF reader: fixed mkvmerge crashing with a \"division by zero\" error due to certain data conditions. Found by fuzzying.
* mkvmerge: fixed mkvmerge aborting with a \"division by zero\" error due to the timestamp scaling factor being 0 after handling certain data constellations. Found by fuzzying.
* mkvmerge: track statistics: fixed a \"division by zero\" error when the content\'s shorter than 1ms. Found by fuzzying.
* mkvmerge, mkvinfo, mkvextract, mkvpropedit: Matroska access class: fixed an invalid memory access under certain data conditions. Found by fuzzying.
* MKVToolNix GIU: IETF BCP 47/RFC 5646 language tags: the GUI will no longer open the language dialog when clicking on a disabled language display widget.
* MKVToolNix GUI: IETF BCP 47 language tags: the \"variants\" combo-boxes were not populated even when the language tag was valid and contained at a variant.
* MKVToolNix GUI: IETF BCP 47 language tags: when no language is selected, at least one of the other components (extended subtags, region, or variants) has something selected and \"private use\" is not empty, the GUI would claim this to be a valid tag, which it isn\'t.
* MKVToolNix GUI: multiplexer: when the tracks/chapters/tags selection changes from \"at least one entry selected\" to \"no entry selected\", the input controls will be reset to their default state and not just disabled. Build system changes:
* `configure` now checks for the presence of the a system-wide installed copy of the JPCRE2 C++ wrapper library for the PCRE2 library and uses that if it\'s new enough (at least v10.32.1). If not, the bundled version will be used as a fallback.
* Sun Sep 06 2020 aloisioAATTgmx.com- Update to version 50.0.0 New feature: IETF BCP 47 language tags:
* I\'ve written up a [nice FAQ https://gitlab.com/mbunkus/mkvtoolnix/-/wikis/Languages-in-Matroska-and-MKVToolNix about the switch to using IETF BCP 47 language tags, how they interact with legacy language elements, how the programs actually behave and how to disable their use if necessary.
* mkvmerge: IETF BCP 47/RFC 5646 language tags: mkvmerge will now accept full BCP 47 language tags for all options taking a language. mkvmerge will always write \"LanguageIETF\" track header elements. If the language tag contains a valid ISO 639-2 language code it will also set the legacy \"Language\" track header element to the included ISO 639-2 code.
* mkvmerge: IETF BCP 47/RFC 5646 language tags: if present the \"LanguageIETF\" track header element will be reported as the `language_ietf` property in JSON identification mode.
* mkvmerge: IETF BCP 47/RFC 5646 language tags in chapters: mkvmerge will now write \"ChapLanguageIETF\" elements when creating chapter atoms, either when reading the simple chapter format or when generating chapters due to the `--generate-chapters` command line option.
* mkvmerge: IETF BCP 47/RFC 5646 language tags in tags: mkvmerge will now write \"TagLanguageIETF\" elements when creating \"simple tag\" elements, either when reading tag XML files or when generating them.
* mkvmerge: IETF BCP 47/RFC 5646 language tags: added an option `--disable-language-ietf` that causes mkvmerge to only write the legacy language elements.
* mkvmerge, mkvpropedit, MKVToolNix GUI\'s chapter editor: IETF BCP 47/RFC 5646 language tags in chapters: when reading XML chapter files the programs will now add \"ChapLanguageIETF\" elements for atoms that don\'t contain them. The values are derived from existing \"ChapterLanguage\" elements.
* mkvpropedit: IETF BCP 47/RFC 5646 language tags: setting/deleting the track language now acts on both the old language element as well as the \"LanguageIETF\" track header element.
* mkvpropedit: IETF BCP 47/RFC 5646 language tags: added an option `--disable-language-ietf` that causes mkvpropedit to apply changes to the `language` track header property only to the legacy language track header element.
* mkvinfo: IETF BCP 47/RFC 5646 language tags: added support for the \"LanguageIETF\" track header element.
* MKVToolNix GUI: multiplexer: added full support for IETF BCP 47/RFC 5646 language tags for both track and chapter languages.
* MKVToolNix GUI: chapter: added full support for IETF BCP 47/RFC 5646 language tags for chapter languages.
* MKVToolNix GUI: header editor: added full support for IETF BCP 47/RFC 5646 language tags for track header languages. The header editor allows editing of the legacy language elements and the IETF BCP 47 language elements independent of each other. Other new features and enhancements:
* mkvmerge: the chapter generation mode `when-appending` now also works with the splitting modes `parts:` & `parts-frames:` when using the `…,+…` syntax for appending other sections of the source file to the same destination file.
* MKVToolNix GUI: multiplexer: the file selection dialogs now include the extension `.dtsma` for DTS files.
* mkvmerge: MP4 reader: sped up parsing MP4 DASH files with a lot of segments (`trun` atoms) quite a bit.
* The PCRE2 regular expression library is now used instead of `std::regex` for big performance improvements in all places where regular expressions are used for parsing big chunks of text, e.g. in the subtitle parsers. Bug fixes:
* MKVToolNix GUI: preferences: under certain conditions changing the selected entry in the page tree on the left did not cause the page shown on the right to be updated.
* mkvmerge: splitting text by a fixed string (e.g. `,`) is now done by using `std::string.find()` instead of using a regular-expression-based text splitting function, greatly improving its performance.
* mkvmerge: MP4 reader: fixed handling of `tkhd` atoms of version 1. Build system changes:
* The PCRE2 library (the 8-bit variant) is now required.
* Sun Aug 02 2020 aloisioAATTgmx.com- Update to version 49.0.0 New features and enhancements:
* mkvmerge: added support for copying the new track header elements `BlockAddIDName`, `BlockAddIDType`, `BlockAddIDValue` and `BlockAddIDExtraData` from Matroska files if they exist.
* mkvinfo: added support for the new track header elements `BlockAdditionMapping`, `BlockAddIDName`, BlockAddIDType`, `BlockAddIDValue` and `BlockAddIDExtraData`.
* MKVToolNix GUI: multiplexer: the list of recent directories can now be edited in the preferences → \"Multiplexer\" → \"Destination file name\".
* MKVToolNix GUI: preferences: the values in the various \"predefined values\" lists can now be re-ordered freely by dragging & dropping. Bug fixes:
* mkvmerge: Matroska reader: when reading tracks (e.g. a subtitle track) from Matroska files with their `default track` flag set to `yes`, and when overwriting those via the command line to `no`, `mkvmerge` would not promote additional tracks of the same type from other files (e.g. another subtitle track from an SRT file).
* mkvmerge: SRT reader: empty lines inside entries were doubled.
* mkvmerge: subtitles: when calculating the rounded duration of each entry the error from rounding the corresponding timestamp will be taken into account.
* mkvextract: SSA/ASS extraction: mkvextract is no longer inserting empty lines before the `Dialogue:` lines.
* mkvextract: USF subtitles: start & end timestamps were too high by a factor of 1.000.000.
* MKVToolNix: info tool: when saving to a text file the checkbox \"Save as default for saving output to text files\" did nothing.
* MKVToolNix: info tool: when saving to a text file in \"all elements in a tree-like structure\" mode, the GUI always stopped at the first cluster regardless of the setting of the \"verbosity\" option.
* MKVToolNix GUI: preferences: when tooltips were disabled the dialogs for adding new entries to the various \"predefined values\" lists were missing their texts.
* configure: fixed detection of QtDBus. Fixes #2886. Build system changes:
* libMatroska v1.6.1 is now required. The bundled version has been updated to that version.
* Sun Jun 28 2020 Luigi Baldoni - Update to version 48.0.0 New features and enhancements:
* mkvmerge: AC-3: file identification will report AC-3 tracks encoded in Dolby Surround EX as codec \"AC-3 Dolby Surround EX\".
* MKVToolNix GUI: multiplexer: on new installations the GUI will now recognize all known ISO 639-2 language codes in file names by default instead of only the top 100 of languages by native speakers.
* MKVToolNix GUI: multiplexer: on new installations the list of \"often used languages\" will by default only contain certain agnostic ones (\"multiple languages\", \"no linguistic content\", \"reserved for local use\", \"uncoded languages\"), \"English\" and the default user interface language. The \"list of spoken languages by native speaks\" isn\'t used anymore.
* MKVToolNix GUI: header editor: added an option to remove all attachments to the tree context menu.
* MKVToolNix GUI: while the GUI is running it will remember the last page that was selected when the preferences dialog is closed. Upon re-opening the preferences that page will be selected by default. Bug fixes:
* mkvmerge: fixed a segmentation fault when exiting prematurely due to write errors such as the destination having run out of space.
* mkvmerge: DTS: fixed wrong channel count for DTS tracks with XCh extensions.
* mkvmerge: MPEG TS reader: fixed detecting h.264/AVC and h.265/HEVC tracks that consist of only a single frame.
* mkvmerge: MPEG TS reader: fixed handling of unbounded PES sizes for tracks that consist of only a single PES packet.
* mkvmerge: MPEG TS reader: PGS subtitle tracks are now exempt from the \"detect bogus subtitle timestamps\" heuristic which could lead to some PGS subtitles not being timestamped correctly. Symptoms were that they were shown at the wrong time or that they were shown indefinitely.
* mkvmerge: MPEG TS reader: when reading MPLS playlists the start timestamps of a play items were handled wrong: all the timestamps of packets read were compared to that start timestamp, dropping those packets whose timestamps were smaller than the play item\'s start timestamp. The correct behavior is to accept all packets as soon as the first one with a timestamp equal to or larger than the play item\'s start timestamp is encountered. This could result in PGS subtitle entries located right at the start of the play item being garbled/lost as they consist of multiple PES packets for which some timestamps are often slightly smaller.
* mkvmerge: MPEG TS reader: when reading MPLS playlists mkvmerge will no longer read the whole M2TS files they reference, processing only the packets lying inside the timestamp range given by the playlists\'s play item\'s start & end timestamps. Instead mkvmerge will use the index information present in corresponding clip information (CLPI) files in order to seek to the nearest file position of the play item\'s start timestamp. Additionally mkvmerge will simply stop processing a file once the end timestamp is seen. This change greatly speeds up processing files from which only small portions must be read.
* mkvmerge: WavPack: fixed support for files created by v5 of the program. Checksums, DSD audio data and non-standard sampling rates are handled correctly.
* MKVToolNix GUI: multiplexer: fixed the cursor being positioned wrong after entering or pasting characters that aren\'t allowed in file names into the \"destination file\" control. Build system changes:
* libEBML v1.4.0 and libMatroska v1.6.0 are now required. Other changes:
* The source code repository\'s main development branch was renamed to `main`.
* Tue Jun 02 2020 Michel Normand - Add _constraints file to avoid build error for ppc64/ppc64le
* Sat May 30 2020 Luigi Baldoni - Update to version 47.0.0 New features and enhancements:
* mkvmerge: chapters: mkvmerge can now read chapters from DVDs if the user specifies the path to a DVD folder structure via the `--chapters …` parameter. By default chapters from the first title will be imported. This can be changed by append `:
