I ran into the same issue some time ago and I confirm that your diagnostic is right.
My feeling about this was that this wasn't easily and cleanly fixable without a huge
refactoring of the FFmpeg rtp/rtsp layer (client AND server).

Maybe one day if I found the motivation in me (or if anyone didn't do it before
me ;-), I will try to do this.
