I would like to use the ATI MPEG Video Decoder to decode some MP4 video's I have but the filter refuses to connect. I think this is because I don't know the FourCC code that the filter want's to use.
I have also found something that appears to be a bug. If you use the ATI MPEG Encoder to encode into MP4, you cannot decode it right away. It exposes the pin with a media subtype of mpeg2.
Is there some documentation on the usage of the ATI encoder / decoder filters?
