int | ff_udp_get_local_port (URLContext *h) |
Return the local port used by the UDP connection. | |
static int | udp_get_file_handle (URLContext *h) |
Return the udp file handle for select() usage to wait for several RTP streams at the same time. | |

If no filename is given to av_open_input_file because you want to get the local port first, then you must call this function to set the remote server address.
url syntax: udp://host:port[?option=val...] option: 'ttl=n' : set the ttl value (for multicast only) 'localport=n' : set the local port 'pkt_size=n' : set max packet size 'reuse=1' : enable reusing the socket
