Windows 7 Filter Tweaker: Media Player DirectShow Decoder

Did you know that Windows 7 uses it’s own DirectShow filters to decode several audio and video formats? If you want to use third party filters then it is not possible without making changes to the registry, which can be quite a hectic process.

Preferred Filter Tweaker for Windows 7 is a small tool that allows you to quickly configure the preferred DirectShow filters with just a few clicks. Suppose you have K-Lite codec pack or any other third party codec pack installed and want to use ffdshow to decoding H.264 video, then you can do so using this tool.

Once you start the program, choose the preferred DirectShow decoding filters and hit Apply. On the left side you will find 32-bit decoders and on the right, 64-bit decoders. By default the filters are selected to Microsoft, this can be useful in case you want to revert back to Microsoft later.

It can set preferred filter for the following video formats – H.264, MPEG-4(Xvid/DivX/MP4V), MPEG-2, VC-1, AAC, MP3, and MP2. The following third party filters are supported:
