Just trying to open some h264-encoded MKV's with ffmpegsource/ffmpegsource2, ffvideosource, etc. Whenever I do, it gives me the error "Can't create decompressor: Unsupported compression method".
The files open and play fine with VLC.
So, is there a certain codec/plugin I need to install? Something I'm doing wrong? Any help is appreciated. Thanks.
