I've tested it like this: Use ffplay to play back a stream over UDP, e.g.
from feng. libavformat usually sets up 5000 as the first receiving port.
The while receiving this stream, send another stream to the same port:
ffmpeg -re -i <whatever> -vcodec mpeg4 -an -f rtp
You should notice lots of errors/warnings in the ffplay session, due to
new stream messing up the other one. (If the first stream played back from
feng also is mpeg4, you might actually get an quite "interesting" mix of
the both video streams.) With this patchset applied and if playing back
the RTSP stream with ?filter_src at the end, it plays back without any
