ffmpeg | branch: master | Can Wu <wu.canus at gmail.com> | Fri Jun 17 13:58:01 2011 +0800| [fc66e231541b91b22f6e0d8257991cc5343db8d5] | committer: Martin Storsjö

udp: Receive on the remote port number, if no local port is set

For a unicast udp stream to localhost:1234, currently
ffplay udp://:1234?localport=1234
works, but
ffplay udp://:1234
doesn't work.
