MKVToolnix v38.0.0 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 38.0.0 "The Silent Type" 2019-10-06

## New features and enhancements

* mkvextract: chapters, tags & cue sheets will now be written to standard
  output if no file name is given, same as if `-` is given as the file name.
* MKVToolNix GUI: job queue: added a new setting in the preferences' "job
  queue & job status" section that, when enabled, will cause the GUI to remove
  all output files created by jobs that are either aborted by the user or that
  end in an error. Implements #2614.

## Bug fixes

* all programs: macOS: fixed file access if the file name (including all path
  components) contains any Unicode character where NFC (Normalization Form
  Canonical Composed) and NFD (Normalization Form Canonical Decomposed)
  differ, e.g. German Umlauts. Fixes #2620.
* mkvmerge: when splitting by chapters the user can now split by chapters
  coming from one of the appended files, too. Fixes #2625.
* mkvmerge: AAC reader: fixed reading codec parameters (channels, sample rate)
  if a file starts with garbage that includes valid-but-bogus AAC
  headers. Fixes #2622.
* MKVToolNix GUI: Hebrew was added to the list of often-used languages so that
  it can be selected by default again. Fixes #2610.
* MKVToolNix GUI: when updating the GUI's settings from v37.0.0 or older, the
  GUI checks if the list of often-used languages equals the built-in list from
  v36.0.0. If it does, it will be updated to the built-in list changed in
  v37.0.0. Fixes #2611.

## Build system changes
* Boost's Operators header library is now required.

# Version 37.0.0 "Leave It" 2019-08-24

## New features and enhancements

* MKVToolNix GUI: the list of often used languages now contains those from
  Wikipedia's "List of languages by native speakers" by default. Also by
  default only those languages will be shown in the language drop-down boxes.

## Bug fixes

* MKVToolNix GUI: multiplexer: fixed a bug in the "make destination file names
  unique" logic that caused an existing number-in-parenthesis at the end of
  the file base name to be removed in certain situations (e.g. when the first
  added file was named `m (3).mkv` and both `m (3) (1).mkv` and `m (3)
  (2).mkv` existed already, the GUI was suddenly use `m.mkv` instead of `m (3)
  (3).mkv`).
* MKVToolNix GUI: on Windows the GUI is built with a slightly older version of
  the Qt library again (5.12.4). The Qt version used in release v36.0.0,
  v5.13.0, lead to crashes when doing certain things such as selecting
  multiple tracks in the multiplexer. Fixes #2605 and #26008.

# Version 36.0.0 "Is That Jazz?" 2019-08-10

## New features and enhancements

* mkvmerge: mkvmerge now allows appending AV1, VP8, VP9, H.264/AVC and
  H.265/HEVC tracks whose pixel dimensions differ. Implements #2582.

## Bug fixes

* source code: fixed building with Boost 1.71.0. Fixes #2599.
* all: fixed the spelling of the H.264 & H.265 codec names.
* mkvmerge: Blu-ray MPLS handling: mkvmerge will now find corresponding M2TS
  files even if the `clip_codec_identifier` playlist item field is not set to
  `M2TS` in the MPLS file. Fixes #2601.
* mkvmerge: fixed handling of text files that use both DOS-style and
  Unix-style line endings resulting in problems such as text subtitle files
  not being parsed correctly. Fixes #2594.

# Version 35.0.0 "All The Love In The World" 2019-06-22

## New features and enhancements

* mkvmerge: JSON identification: the "codec name" track property will be
  output as `codec_name`. The JSON schema has been bumped to v12 for this
  change.
* MKVToolNix GUI: job queue: added a new type of action to execute after job
  completion: deleting source files for of multiplexer jobs. As this is a
  destructive operation, the action is disabled by default. Implements #869
  and #2570.

## Bug fixes

* mkvmerge: the "codec name" track property wasn't copied from Matroska
  files. Fixes #2566.
* MKVToolNix GUI: multiplexer: Windows: clearing the destination file name
  will reset the tab name to "\" again. Fixes #2571.
* MKVToolNix GUI: multiplexer: the file types were not re-translated if the UI
  language was changed. Fixes #2572.

# Version 34.0.0 "Sight and Seen" 2019-05-18

## Bug fixes

* mkvmerge: all subtitle frames are now treated as key frames in order to fix
  wrong data in source files. Fixes #2541.
* mkvmerge: AV1: fixed frame timestamp calculation when reading bitstreams
  that lack timing information from IVF files. Fixes #2553.
* mkvmerge: Matroska reader: fixed an infinite loop that could happen with
  large video frames and applied timestamp files due to too much data being
  buffered at the wrong time. Fixes #2550.
# Version 33.1.0 "Primrose" 2019-04-15

## Bug fixes

* MKVToolNix GUI: multiplexer: Windows: using UNC paths
  (e.g. `\\server\Videos`) when the option "automatically set the destination
  file name" was set in the preferences, the GUI would create a destination
  file name with forward slashes (e.g. `//server/Videos/outputfile.mkv`), a
  syntax not supported by `mkvmerge`. Fixes #2533 & #2534.
* build system: the programs were accidentally built without stack protection
  (`-fstack-protector-strong`) on recent versions of gcc and clang.

# Version 33.0.0 "A Little Bit of Madness" 2019-04-12

## Bug fixes

* mkvinfo: when using the `--size` option, mkvinfo will now report the
  correctly if an element has an unknown size. Part of the fix of #2530.
* MKVToolNix GUI: info tool: clusters with an unknown size will now be read
  and displayed correctly. Part of the fix of #2530.
* MKVToolNix GUI: multiplexer: Windows: trying to open Blu-ray index or
  playlist files failed when the path to the files contained symbolic links
  (e.g. when mounting a drive in a sub-folder via Windows' disk management
  utility). Fixes #2522.
* MKVToolNix GUI: multiplexer: if a destination file names ends with a number
  in parenthesis (e.g. a year such as "(2017)"), that number will not be
  stripped anymore during the process of ensuring the destination file name is
  unique. Only those suffixes added automatically in prior attempts to make
  the file name unique will be removed. Fixes #2521.
* MKVToolNix GUI: multiplexer: Windows: the GUI will let the user change the
  drive letter part of the destination file name freely again and only verify
  its validity right before starting to mux/adding to the job queue. Before it
  tried to force that into something valid, often resulting in unintentional
  paths (such as "C:\users\…\DC\files\…"). Fixes #2527.

# Version 32.0.0 "Astral Progressions" 2019-03-12

## New features and enhancements

* mkvinfo: when sizes are output the size of the element's data portion is
  output in addition to the element's total size.
* MKVToolNix GUI: info tool: the element's data portion is
  shown as an extra column.
* MKVToolNix GUI: multiplexer: added column "Delay" to the track list
  containing the additional delay to apply during multiplexing. Implements
  #2506.

## Bug fixes

* all: fixed handling of Unicode code points > U+FFFF. Fixes #2516.
* mkvmerge: Windows: mkvmerge was crashing with an exception when trying to
  identify certain files that can be used on Blu-rays (such as MPEG transport
  streams of MPLS play list files) and when the file name was given as a UNC
  path (e.g. `\\servername\sharename\path\to\file.m2ts`). The GUI emitted
  errors such as "the JSON output could not be parsed" in that case. Fixes
  #2507.
* MKVToolNix GUI: the portable mode wasn't detected correctly when the current
  working directory the GUI was started from wasn't the directory the GUI's
  executable file was located it. Examples for when this is the case are
  Windows' "send to" or "open with" functions. Fixes #2501.
* MKVToolNix GUI: multiplexer: using button to change the current destination
  directory to one of the recently used ones did not update the file name
  according to the "make file name unique" setting. Part of the fix of #2519.
* MKVToolNix GUI: multiplexer: the function "set destination file name from
  selected file's name" will now only change the destination file's name but
  not its path. Part of the fix of #2519.

## Build system changes

* libEBML v1.3.7 and libMatroska 1.5.0 are now required as they fix their
  handling of Unicode code points > U+FFFF (see #2516).
