关于 Win7DSFilterTweaker

Windows 7 uses its own codecs for decoding several audio and video formats. Using third party DirectShow filters instead of the native filters is not possible without making difficult changes to the Windows Registry.
Windows 7 使用它自己的编解码器（滤镜）来解码某些音频与视频格式。想用第三方滤镜替换系统内置滤镜的话，需要在 Windows 注册表里面作繁难的修改，否则无法实现。

The Win7DSFilterTweaker tool allows you to configure your preferred DirectShow decoders with just a few mouse clicks. It is quick, easy, and changes can always be undone.
Win7DSFilterTweaker 可以让你轻松点击几下鼠标来修改 DirectShow 滤镜偏好设置。快速、容易且所作的修改总是可以撤消。

If you for example prefer to use ffdshow or CoreAVC for decoding H.264 video then you can do so by using this tool.
比如说你想用 ffdshow 或 CoreAVC 来解码 H.264 视频，就可以利用这个工具来达到目的。

This tool is particularly useful for the Microsoft players, namely Windows Media Player and Media Center. Certain advanced third party players, such as Media Player Classic, are already capable of using third party filters without using this tool.
本工具尤其适用于 Windows Media Player 和 Media Center。一些高级的第三方播放器比如 Media Player Classic 本身就能够使用第三方滤镜，不需要借助此工具。


Important NoteThe changes that this tool makes to the preferred filter settings of Windows only have effect when a player uses DirectShow.
Windows Media Player and Media Center use a new framework called Media Foundation instead of DirectShow when playing certain file formats. In that case they will always use the Microsoft decoders, and not any third party DirectShow filters. Examples of file formats that are played using Media Foundation are: .m2ts, .mp4, and .mov.
This tool has the capability to disable the use of Media Foundation for specific file extensions. The only negative side effect of those tweaks is that thumbnails will not be generated in Windows Explorer.
This tool is also capable of completely disabling Media Foundation and other Microsoft playback components by renaming certain files. However, you should be aware that doing so might have noticeable side effects. For example, playback of live TV in Media Center could stop working. But in any case, any change made by the tool can easily be undone to restore the system to its original state.
