Thanks for the explanations. I see this in the ticket discussion:

# FFmpeg(AV muxer) ==> APP ==> FFmpeg(RTP muxer)

This looks strange to me: what is the "AV muxer" for exactly? Why not just
five the packets to the RTP muxer?

# This is useful to create verbose statistics about each individual data
# stream in the application.

It seems to me that you could gather the statistics from the AVPackets
before the muxer, could you not?

# this structure is needed to use also proprietary RTP packetizers beside the
# ones from ffmpeg.

This looks interesting. Can you explain what is missing from the API to be
able to use them? And also: what packetizer are missing from FFmpeg?
