Hi all.

I was wondering if anyone could give me an explanation on how FFMPEG
controls the bitrate when its streaming video using rtp protocol.
Seems that the bitrate and fps (frames per second) are controled via the
RTCP receiver reports.
I was wondering how it is done, i.e. which fileds of RTCP RR packet is used
and how is the bitrate (of encoded video) calculated in this matter.
I already have search nearlly the hole ffmpeg code in order to understand
it, but I have not been succeded yet.
Can anyone help?

Thanks alot in advance.
