Hmm, yeah.  Being prompted by the visible problem in ivfenc I didn't really think this through properly.

While they aren't a hard requirement, it seems to me that for h264 and hevc it might be a good idea to have this dependency?  I agree it's not helpful on the others, since they are generally not used.

Updated patch with just the IVF muxer enclosing.

Thanks,
