Avidemux 特色

用户友好的界面
在快速安装过程之后，您可能会注意到用户界面是多么简单。 GUI 上填充了一些菜单和一些用于播放功能的控件。

用法：一旦你打开了一个可以使用的视频文件，你可以通过指示一个选择并按下键盘上的 Delete 来裁剪它（你甚至可以裁剪黑条），或者通过选择输出来重新编码它文件格式从下拉列表中保存。

支持各种格式
幸运的是，Avidemux 支持各种视频格式，包括 AVI，FLV 和 MPEG，还支持音频格式，如 MP3，WAV 和 OGG。

此外，您还可以利用解码器选项，处理工具，过滤器，配置帧速率，字形编辑器等等。

当然，就像任何其他应用程序一样，Avidemux 也有其自身的一些缺点。例如，该程序没有内置的帮助文件（对于初次使用的用户来说可能非常麻烦），并且在某些时候它会发生卡和崩溃）。

可靠的应用程序，可让您执行小的调整
事实上，Avidemux 非常强大，大多数用户肯定会爱上它。

Avidemux 2.7.8 : Changelog
New Features
Many new video filters added by courtesy of <a href=”https://github.com/szlldm”>szlldm</a>
A dedicated MOV muxer is now available, replacing silent fallback to MOV muxing mode within the MP4 muxer.
A subset of color info relevant for HDR support is retained in copy mode when both input and output video are stored in Matroska / WebM containers. Settings to add or override color info have been added to MKV and WebM muxers.
The indexer in the MPEG-TS demuxer now detects resolution changes in MPEG-2 and H.264 streams which are entirely unsupported and suggests aborting indexing. If the user chooses to continue, it records file offsets of all resolution changes to the log. This allows advanced users to split the file at these offsets using other tools like head and tail into chunks which can be processed with Avidemux.
YUV varieties of the lossless Ut Video codec are supported now for decoding and encoding via bundled FFmpeg libraries.
Uncompressed 24-bit audio is now supported for a subset of file formats.
Limited support for 7.1 channel layout.
Decode and stream copy support for XLL substream in DTS audio tracks.
Audio properties are now updated on resuming playback. This allows to start saving after an audio format change. When audio format changes during playback, the FFmpeg-based audio decoder will output silence and keep format rather than producing garbage.
An option to keep the identity of markers A and B instead of swapping them automatically has been added to Preferences.
The keyboard shortcut for “Delete” action has been made customizable with alternative keyboard shortcuts enabled.

Other Enhancements
Multi-threaded video decoding is now available for the bundled FFmpeg. On powerful multi-core CPUs, this can drastically improve decoding performance. A maximum of 8 threads can be created, but a conservative custom upper limit of 4 is recommended. Values above 8 cause decoding failures. Multi-threaded decoding and HW accelerated decoding are mutually exclusive, changes require application restart to have effect.
The maximum supported resolution has been increased to 8192×8192
The bundled FFmpeg has been updated to the 4.2.4 release.
Non-standard display aspect ratios can be configured in MP4 muxer by specifying display width.
MP4 muxer accepts now MPEG-1 and MPEG-2.
The configuration dialog of the x265 video encoder plugin enjoyed massive cleanup and refactoring by <a href=”https://github.com/xyzzy42″>Trent Piepho </a>, more Adaptive Quatization Variance methods have been added.
Python interface has been substantially extended, includes now methods to query segment properties, the number and filenames of loaded videos, PTS of keyframes, methods to seek to time with preview updated, to open file dialogs filtered by extension and a built-in method to split filename extension from a given path.
Scripting shell now supports unicode characters.
On macOS, files can be loaded via Finder context menu or by dropping them onto Avidemux icon in the dock.
On Linux, Jobs GUI and the CLI executable can be launched from AppImage by creating a symlink with _jobs or _cli in filename respectively and running the AppImage via this symlink.

Bugfixes
Rate control was broken in some video encoders, especially in VP9 and in NVENC-based encoders, fixed now.
Multiple issues in cut point checks for H.264 and HEVC streams in copy mode, leading to incorrect check results, were identified and resolved.
The first two frames of external AC3 or EAC3 audio tracks are not dropped anymore. This regression from enhanced protection against false positives, added 3 years ago, has been finally identified and fixed.
Indexing of MPEG-TS files with HEVC video was broken when video stream lacked access unit delimiters. The issue was identified and fixed right after 2.7.7 had been tagged as released and is the reason why version 2.7.7 was superseded by 2.7.8.
VU meter was grossly ahead of audio output on Windows, now it is just a tiny little bit ahead.
Numerous other fixes and overall polish.
