MKV并不是通常意义上的视频格式，而是一种“容器”。简单的来说，我们可以将所有的视频、音频、字幕乃至各种文件封装进这个“容器”，而解码工作由相应的解码器来完成。由于其“容器”的特性，所以他几乎能够包容所有的的影音文件，即任何的影音文件可以通过封装成为MKV文件。MKVtoolnix 就是这样一种可以修改、检查和合并MKV文件的工具集。

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。

1。MKV封装风头日盛，尤其是那些多声轨、多字幕的高清MKV大片更是倍受青睐，丝丝入扣的影像和逼真震撼的音响让人流连忘返，这也是高清MKV最大的卖点。但在播放高清 MKV及格式转换等方面遇到了不少问题，例如播放迟滞、音画不同步及字幕不匹配等。这种情况要利用 MKV合成工具MKVtoolnix的MKVmerge（mmg）重新封装MKV文件方可解决。

2。很多高清MKV下载网站采取分段处理的方式，这使得我们看电影时不能够“一气呵成”，那么有什么办法可以将分段的部分拼接起来，又不影响观看质量呢？带来利用MKVtoolnix这款小工具将多个MKV格式的影片合并在一起的方法。

# Version 103.0 “The Darkness” 2026-10-18

## New features and enhancements
* mkvmerge: AVC/H.264: the stereo mode is now set from the frame packing
arrangement SEI message in the video stream if neither the command line
nor the container specifies one. This works for MP4, Matroska, AVC
elementary stream and MPEG transport stream input and is already known
during file identification. Implements the AVC part of #6309.
* mkvmerge: HEVC/H.265: the stereo mode is now set from the frame packing
arrangement SEI message in the video stream if neither the command line
nor the container specifies one. This works for MP4, Matroska, HEVC
elementary stream and MPEG transport stream input and is already known
during file identification. Implements the HEVC part of #6309.
* MKVToolNix GUI: multiplexer: added new actions to the tracks context menu
for enabling/disabling all items belonging to the same source file as the
selected item. Implements #6318.

## Bug fixes
* mkvmerge: MP4 reader: fixed losing video frames at the end of the file due
to flushing the packetizers too early (when the first track ends instead of
only when all tracks in the file have ended). Another byproduct is that
`BlockDuration` attributes aren’t set for the last frame when they aren’t
needed anymore. Fixes #6320.
* MKVToolNix GUI: multiplexer: when identification fails due to an
unrecognized or unsupported format, clicking the “Cancel” button in the
error dialog shown no longer locks up the GUI in the state of
“identification is still running”, which disabled most elements. Fixes
#6298.
* MKVToolNix GUI: chapter editor: when adding chapters mandatory elements set
to their default values are removed in the underlying data structures. This
restores consistency to how the chapter editor worked when copying values
from the UI into them for the selected chapter. The result is that those
elements won’t show up in saved XML/Matroska files even if they have never
been selected in the UI. Fixes #6294.
* macOS: GUI: fixed check boxes in lists such as the multiplexer’s track list
being invisible on macOS 27 by patching the Qt bundled with the app. Patch
by corticalcode, based on the fix J.D. Purcell proposed in QTBUG-150017.
Fixes #6307.
