The boundary of execution for "one frame" is ambiguous to start with. Where
does rtsp protocol handling goes? How do you correlate packets captured as
UDP packet and processed in the jitterbuffer and frames? How do you
seperate cpu usage per frame for element running multiple threads
internally and with buffering like codec/avdec_h264? I think this one of
these simple idea that are just not possible in streaming. This is quite
different from graphics pipeline in this regard.

If possible, i prefer doing this with python, by building the pipeline with
