int ff_udp_set_remote_url | ( | URLContext * | h, |
const char * | uri | ||
) |
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 'overrun_nonfatal=1': survive in case of circular buffer overrun
