It might be that instead all the code below this needs to be inverted for the
GST_PAD_SRC case (flip caps and othercaps). The code was there to make
assumptions about the PAR of caps without explicit PAR. Upstream caps without
PAR are assumed to have 1/1 PAR while downstream caps without PAR are assumed
to have [0,MAX] PAR.

The code below that tries to keep the DAR of the upstream caps and tries to
select downstream caps according to that. For the case of GST_PAD_SRC it
probably has to change "caps" instead of "othercaps". Unfortunately I wasn't
able to get this called with GST_PAD_SRC at all in the last minutes :)

Anyway, I think the patch is wrong
