3月5日更新：MKV视频封装工具 MKVToolnix 54.0.0 中文绿色便携版-百度云

mkv：通用视频文件，有的包含音频，也可以只有视频； Matroska的目标就是要取代旧式的媒体封装格式，其中最主要的目标就是AVI。 AVI已经诞生十几年了，目前它依然还保持着旺盛的生命力，但其在支持新的音视频编码上非常困难，在非微软平台使用也不够方便。而Matroska使用的是一种开放的架构，拥有众多的先进特性，并且能跨平台使用，这是AVI所望尘莫及的。

Due to two nasty bugs in v36 I’m releasing v37 sooner than anticipated. This release fixes both of the bugs; see below for details.

There’ve been no changes regarding packaging since the previous release.

You can download the source code or one of the binaries. The Windows and macOS binaries as well as the Linux AppImage are available already. The other Linux binaries are stil being built and will be available over the course of the next couple of hours.

Here are the NEWS since the previous release:

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.

功能特性

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。
