--- Comment #2 from Wim Taymans <wim.taymans at gmail.com> 2013-11-28 16:10:41 UTC ---
The reason is that ffmpeg sends a dummy RTP packet to the RTSP server with SSRC
of 0 (and all other fields 0 too). When you start 2 clients, this causes a
collision on the server because now there are 2 clients with the same SSRC and
different IP:port pairs. There is a bug in the code to deal with the collision
that got fixed with this commit:

    rtpsession: don't unref buffer twice

    Cleaning the packet info will already unref the buffer.
