Version 51.0.0 "I Wish" 2020-10-04

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. Implements #2919.
  • 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. Fixes #2937.
  • 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. Fixes #2923.
  • 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. Fixes #2924.
  • 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. Fixes #2927.

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. Implements #2929.

Version 50.0.0 "Awakenings" 2020-09-06

New feature: IETF BCP 47 language tags

  • I've written up a nice FAQ entry 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. Part of the implementation of #2419.
  • 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. Part of the implementation of #2419.
  • 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. Part of the implementation of #2419.
  • 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. Part of the implementation of #2419.
  • 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. Part of the implementation of #2419.
  • 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. Part of the implementation of #2419.
  • 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. Part of the implementation of #2419.
  • MKVToolNix GUI: multiplexer: added full support for IETF BCP 47/RFC 5646 language tags for both track and chapter languages. Part of the implementation of #2419.
  • MKVToolNix GUI: chapter: added full support for IETF BCP 47/RFC 5646 language tags for chapter languages. Part of the implementation of #2419.
  • 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. Part of the implementation of #2419.

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. Implements #2898.
  • MKVToolNix GUI: multiplexer: the file selection dialogs now include the extension .dtsma for DTS files. Implements #2901.
  • mkvmerge: MP4 reader: sped up parsing MP4 DASH files with a lot of segments (trun atoms) quite a bit. Part of the fix of #2900.
  • 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. Part of the fix of #2899.

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. Fixes #2895.
  • 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. Part of the fix of #2899.
  • mkvmerge: mkvmerge will now read-buffer file I/O when probing text file formats which increases its speed significantly on Windows. Part of the fix of #2899.
  • mkvmerge: MP4 reader: fixed handling of tkhd atoms of version 1. Fixes #2900.

Build system changes

  • The PCRE2 library (the 8-bit variant) is now required.
