MKVToolnix 跨平台的Matroska处理工具
mkvtoolnix (又叫Matroska toolkit)，是一套功能强大的mkv(Matroska)格式制作和处理的工具，支持将多种视频、音频、字幕等格式封装成mkv格式。mkvtoolnix新版本提供了安装程序。
MKVToolNix v11.0.0 发布了，该版本修复了 HEVC/h.265 和 AVC/h.264 解析器中出现的几个重要错误。在修复的错误中会静默地产生一些无效的文件。建议大家更新。
此版本还包括对 GUI 的一些较小的增强功能。值得注意的是实现的这几个功能是以前被要求的：在当前工作完成后播放声音或关闭计算机。实现是非常灵活的，而且不限于这两个动作。

新特性和增强
mkvmerge: FLAC reader: added support for handling embedded pictures as attachments. Implements #1942.
mkvmerge: MP4 reader: merged pull request #1804 adding support for parsing the "COLR" atom and including its values as track headers.
MKVToolNix GUI: watch jobs: the user can now have the GUI execute an action once as soon as the current job or the whole queue finishes. The actions are the same ones that can be configured to be run automatically after job or queue completion.
MKVToolNix GUI: implemented several built-in actions that can be executed either on special events or once via the "watch jobs" tool. These are: playing an audio file (implemented for all operating systems); hibernating, sleeping and shutting down the computer (only implemented for Windows and for Linux systems using systemd).
MKVToolNix GUI: multiplex tool: added a new option for what to do after starting to multiplex/adding to the job queue: "close current settings" will close the current multiplex settings without opening new ones.
Bug 修复
mkvmerge: AAC parser: fixed mis-detection of certain data as valid ADTS AAC headers resulting in memory allocation failures. Fixes #1941.
mkvmerge: AVC/h.264 parser: mkvmerge will now ignore bogus timing information in the sequence parameter sets (values indicating more than 100000 progressive frames per second). Fixes #1946.
mkvmerge: AVC/h.264 & HEVC/h.265 parsers: all trailing zero bytes will now be removed from NALUs. Fixes #1952.
mkvmerge: HEVC/h.265 parser: fixed copying the `bitstream_restriction_flag` and all dependent fields in the VUI parameters of the sequence parameter sets. Fixes #1924.
mkvmerge: HEVC/h.265 parser: fixed the calculation of the number of parameter set arrays in the HEVCC data structure stored in CodecPrivate. Fixes the video-related part of #1938.
mkvmerge: HEVC/h.265 parser: fixed writing superfluous and uninitialized bytes at the end of the HEVCC data structure stored in CodecPrivate. Another fix for the video-related part of #1938.
mkvmerge: HEVC/h.265 parser: fixed the assumption that the HEVCC data structure always includes arrays for all parameter set types (VPS, SPS, PPS and SEI), and that the order is always VPS → SPS → PPS → SEI. Instead now only the arrays actually present are parsed, and they can be in any order. This fixes mkvinfo’s output for Matroska files created from files such as the one from #1938.
mkvmerge: AVC/h.264 packetizer: when reading a framed track (e.g. from Matroska or MP4 files), specifying a default duration as fields (e.g. `50i`) would result in double the actual duration for each frame and the track’s default duration header field. Fixes #1916.
mkvmerge: Matroska reader: invalid track language elements are now treated as if they were set to `und` = "undetermined". See #1929 for context.
mkvmerge: MPEG TS reader, AAC: mkvmerge will now require five consecutive AAC headers with identical parameters before track type determination is considered valid. This avoids false positives and consequently wrong track parameters. Fixes the audio-related part of #1938.
mkvmerge: fixed an endless loop in certain circumstances when splitting by `parts` or `parts-frames` and the start of the file is discarded. Fixes #1944.
MKVToolNix GUI: multiplexer tool: the "show command line" dialog will no longer include the mkvmerge executable’s location as the first argument for the two "MKVToolNix option files" escape modes. Fixes #1949.
MKVToolNix GUI, header editor: empty track language elements are now treated the same as those set to invalid ISO 639-2 codes: as if they were set to `und` = "undetermined". See #1929 for context.
构建系统更改
bug fix: configure now looks for the `strings` binary by using the `AC_CHECK_TOOL()` autoconf macro. That way it will be found in multiarch setups, too. Fixes #1923.
bug fix: the environment variable USER_CXXFLAGS was accidentally removed from the compiler flags in release 9.8.0. It’s been re-added. Fixes #1925.
The `.desktop` files have been renamed to `org.bunkus.mkvtoolnix-gui.desktop` and `org.bunkus.mkvinfo.desktop`. This allows Wayland compositors to associate the correct icons with running applications for e.g. task switchers. Fixes #1948.
Qt’s multimedia component is required for compilation of the GUIs since version 11.0.0.
