So it looks like there are problems with both approaches. :)

A couple of questions:

(i) Is it only qtdemux that must set fixed src caps before the autoplugger can
link downstream elements, or is this generally true of all demuxers?

(ii) If it's generally true of all demuxers, is there a reason that would make
it fundamentally impossible for an autoplugger to link downstream elements to a
demuxer src pad that has unfixed caps, or is it just that this hasn't been
implemented in decodebin?


I guess what I'm getting at is whether the real issue is with the autoplugger,
and whether that's where we need to be looking for a solution; the above two
approaches both seem to be working around the fact that the autoplugger can't
link downstream elements to src pad caps of qtdemux that are as-yet unfixed.

(Apologies if I've misunderstood caps/autoplugging!)
