If adding gstkrkr works even without this MR, my guess is that those programs tell DirectShow to automatically pick the appropriate decoders, which ends up using CLSID_decodebin_parser instead of CLSID_CMpegVideoCodec; you were missing the codec, but nothing else.

If adding this MR makes it hang or otherwise screw up, that's definitely something I should look into...
