I see, this is only with 0.11, right? Not with latest GIT (or releases) of
0.10? The pad caps compatibility checks changed there and are stricter (and
more correct) now.


IMHO at least the width/height should always be set inside the MPEG4 streams
and thus be set on the output caps of mpeg4videoparse. Don't know about the
framerate but it seems to be optional, which makes sense. Could you check if
this is correct and prepare a patch that always sets width/height and adds
width/height to the template caps?

The second part would be ffdec_mpeg4 or in general the ffmpeg decoders. They
really shouldn't require a framerate at all on the template caps and most of
the probably shouldn't require width/height either.
