Hi,
playbin currently hangs in prerolling in several situations which could all be
triggered by the sample from bug #542646.

a) If the caps on the pad are not a subset of the pad template caps. For this
remove the check in gstmpeg2dec.c:631 and play the file from the above
mentioned bug with playbin. It will simply stuck in prerolling (also mpeg2dec
pushes no buffers because the file is corrupted, maybe that's part of the
problem. OTOH EOS is sent).

b) If the decoder element returns GST_FLOW_ERROR but no output is done yet...
for this just play the file from the bug in playbin with current CVS of
mpeg2dec. The error is properly returned but the pipeline stalls in prerolling.
