Unfortunately, there is no specific "metadata flag" for this particular purpose
that I know of.

AU = Access Unit, that is, have rtph264depay output AU (access units) rather
than individual NALUs (though that may often coincide).  That way, e.g. SPS and
PPS should get merged into one buffer with other NALUs and some DELTA_UNIT (or
not) ambiguity would be lifted.
