MKVToolNix v28.0.0 发布了，这是首个支持 AV1 的稳定版本。mkvmerge 可从 Matroska/WebM, MP4, IVF 容器文件和原始 OBU 流中读取它。mkvextract 会将其解压到 IVF 文件。除此之外就是一些 bug 修复，以及对可用性进行了改进。

其他一些变更

新特性和功能增强

• mkvmerge: AV1 parser: updated the code for the finalized AV1 bitstream
  specification. Part of the implementation of #2261.

• mkvmerge: AV1 packetizer: updated the code for the finalized AV1-in-Matroska
  & WebM mapping specification. Part of the implementation of #2261.

• mkvmerge: AV1 support: the --engage enable_av1 option has been removed
  again. Part of the implementation of #2261.

• mkvmerge: MP4 reader: added support for AV1. Part of the implementation of
  #2261.

• mkvmerge: DTS: implemented dialog normalization gain removal for extension
  substreams. Implements #2377.

• mkvmerge, mkvextract: simple text subtitles: added a workaround for simple
  text subtitle tracks that don’t contain a duration. Implements #2397.

• mkvextract: added support for extracting AV1 to IVF. Part of the
  implementation of #2261.

• mkvextract: 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.

• mkvmerge: VP9: mkvmerge will now create codec private data according to the
  VP9 codec mapping described in the WebM specifications. Implements #2379.

• MKVToolNix GUI: automatic scaling for high DPI displays is activated if the
  GUI is compiled with Qt ≥ 5.6.0. Fixes #1996 and #2383.

• MKVToolNix GUI: added a menu item ("Help" → "System information") for
  displaying information about the system MKVToolNix is running on in order to
  make debugging easier.

• MKVToolNix GUI: 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. Implements #2230.

Bug 修复

• mkvmerge: JSON identification: fixed a bug when removing invalid UTF-8 data
  from strings before they’re output as JSON. Fixes #2398.

• mkvmerge: MP4/QuickTime reader: fixed handling of PCM audio with FourCC
  in24. Fixes #2391.

• mkvmerge: 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. Fixes #2393.

• mkvextract: 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: 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. Fixes #2406.
