push frames downstream asap instead of waiting until they're ejected from the
DPB

This patch works for all of the camera sources that I tried, including some
that that produce non-trivial GOP patterns like I(BBrBP)*.  Still, it relies to
some extent on the POC being counted by 2s. So it might need some tweaks to
handle other encodings, for which I didn't have any examples to test against.
