MKVToolnix v30.1.0 Final x86/x64 多语言中文正式版-MKV封装工具

MKV 是一种优秀的多媒体容器格式，它可把多种不同编码的视频及16条或以上不同格式的音频和语言不同的字幕封装到一个 MKV 文件中，而 MKVToolNix 是一款免费开源的 MKV 编辑器和工具集，能够合成、编辑 Matroska MKV 文件。

MKVToolNix 包含了以下几个 MKV 专用处理工具：
*mkvmerge：将多媒体文件封装、合并、混流为 MKV 文件；
*mkvinfo：输出 MKV 文件组件和编码信息；
*mkvextract：从 MKV 文件中提取视频、音频和字幕轨道；
*mkvpropedit：直接修改现有 MKV 文件的属性而无需重混流；
*mmg：mkvmerge GUI，并包含了章节编辑器和头部编辑器。

MKVToolNix 中的 Mkvmerge GUI 允许你导入多个视频、音频、字幕轨道，混流合并一个新的 MKV 文件，并可以设置导出视频的宽高比、显示比例、帧频等等。

MKVToolNix 中的 MKVExtractGUI 则可以从现有的 MKV 文件中提取其中的一个或多个视频、音频或者字幕信息，是专业的 MKV 分离工具。

MKVToolNix 是专用的 MKV 剪辑工具，提供了4种 MKV 切割模式，包括按尺寸、按时长、按特定时间码和按分段，都是无损剪辑、分割 MKV 过程，能够同步切割视频、音频和字幕轨道。比之前介绍的所有支持 MKV 分割的工具都要好用，包括 Boilsoft Video Splitter、SolveigMM AVI Trimmer 等。

更新记录：

# Version 30.1.0 "Forever And More" 2019-01-05

## Bug fixes

* build system: fixed building on non-UTF-8 locales. Fixes #2474.
* MKVToolNix GUI: multiplexer: implemented a workaround for drag & drop not
  working on macOS with Qt 5.12 due to a bug in Qt 5.12. Fixes #2472.
* MKVToolNix GUI: chapter editor: when opening a Matroska/WebM file that
  doesn't contain chapters and later saving chapters back to them, the editor
  was truncating the file down to a couple of KB in size. This was a
  regression introduced with the implementation of #2439 in v30.0.0 Fixes
  #2476.


# Version 30.0.0 "Interstellar" 2019-01-04

## New features and enhancements

* mkvextract: WAV extractor: mkvextract will now write W64 files instead of
  WAV files if the file name extension is `.w64` or if the final file size is
  bigger than 4 GB, the file size limit for WAV files. Implements #2458.
* MKVToolNix GUI: multiplexer: a new button was added next to the "destination
  file" controls. Clicking it shows a menu with the ten most recently used
  output directories. Selecting one of them will change the destination file
  to the selected directory keeping the file name. Implements #2468.
* MKVToolNix GUI: multiplexer (preferences): the ten most recently used values
  for the "relative output directory" and "fixed output directory" settings
  are now saved. The corresponding settings have been changed into combo boxes
  allowing quick access to those recent values.
* MKVToolNix GUI: multiplexer (preferences): the predefined split sizes and
  durations can now be customized in the preferences.
* MKVToolNix GUI: chapter editor: added an option in the "Chapter editor" menu
  for appending chapters from an existing file to the currently open editor
  tab. Part of the implementation of #2439.
* MKVToolNix GUI: chapter editor: added an action in the context menu for
  copying the selected entry and all of its children to another open editor
  tab. Part of the implementation of #2439.

## Bug fixes

* mkvmerge: all files opened for writing will now be flushed once before
  they're closed. This ensures the operating system actually writes all cached
  data to disk preventing data loss in certain situations such as power
  outages or buggy drivers in combination with suspending the computer. Fixes
  #2469.
* mkvmerge: AAC: under certain conditions 8 channel audio files were taken for
  7 channel ones.
* MKVToolNix GUI: multiplexer: removing a file added as an "additional part"
  will no longer cause a crash. Fixes #2461.
* source code: fixed compilation with Boost 1.69.0 after API-breaking change
  to the `boost::tribool` class. Fixes #2460.

# Version 29.0.0 "Like It Or Not" 2018-12-01
## Important notes
* The string formatting library used was switched from `boost::format` to
  [`fmt`](http://fmtlib.net/). See the section "Build system changes" for
  details.

## New features and enhancements
* MKVToolNix GUI: added an option in the preferences for disabling automatic
  scaling for high DPI displays. Implements #2415.
* MKVToolNix GUI: the GUI will now prevent the system from going to sleep
  while the job queue is running. This feature is implemented for macOS,
  Windows and Linux/Unix systems where the `org.freedesktop.login1.Manager`
  D-Bus interface is available. Implements #2411.

## Bug fixes
* mkvmerge: chapter generation: the start timestamps of chapters generated in
  intervals was wrong for files whose smallest video timestamp was bigger than
  0. Fixes #2432.
* mkvmerge: MP4 reader: fixed handling of atoms whose size exceeds the parent
  atom's size. Fixes #2431.
* mkvmerge, MKVToolNix GUI's chapter editor: the chapter name template will
  now also be used when reading Ogg-style chapter files with empty chapter
  names. Fixes #2441.
* mkvextract: AAC: mkvextract will now write the program config element (PCE)
  before the first AAC raw data packet if the PCE is present in the
  `AudioSpecificConfig` structure in the `Codec Private` Matroska element. The
  PCE carries vital information about the number of channels and is required
  in certain cases. Fixes #2205 and #2433.
* mkvpropedit, MKVToolNix GUI's header editor: in situations when a one-byte
  space must be covered by a new EBML void element the following element must
  be moved up instead. If that moved element is a cluster, the corresponding
  cue entries will now be updated to reflect the cluster's new position. Fixes
  #2408.
* MKVToolNix GUI: Windows: the application manifest is now included properly
  so that Windows actually recognizes it. See #2415.

## Build system changes
* Qt's D-Bus implementation is now required for building on systems other than
  macOS and Windows,
* The `boost::format` library is not used anymore.
* The [`fmt` library](http://fmtlib.net/) is now required. Versions 3 and
  newer are supported. As not all Linux distributions include packages for the
  library, its release 5.2.1 comes bundled with MKVToolNix. The `configure`
  script will check for a system version of the library and use it if present
  and recent enough. Otherwise it will fall back to the bundled version and
  link that statically.
