Same as the process virtual function, but slightly more
efficient, since it is passed the rtp buffer structure that has already
been mapped (with GST_MAP_READ) by the base class and thus does not have
to be mapped again by the subclass. Can be used by the subclass to process
incoming rtp packets. If the subclass returns a buffer without a valid
timestamp, the timestamp of the input buffer will be applied to the result
buffer and the output buffer will be pushed out. If this function returns
null, nothing is pushed out. Since: 1.6.
