It's certainly possible decoders differ in attributes they use, but here
what matters is compressed/uncompressed distinction, and not whether
it's H264 or not, I think. So turning this in two paths, with
possibility to add more format-specific checks for compressed part, will
make this more compact and easy to follow.
