Function Documentation

int ff_rtp_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.

Parameters

h	media file context
uri	of the remote server

Returns

zero if no error.

url syntax: rtp://host:port[?option=val...] option: 'ttl=n' : set the ttl value (for multicast only) 'rtcpport=n' : set the remote rtcp port to n 'localrtpport=n' : set the local rtp port to n 'localrtcpport=n' : set the local rtcp port to n 'pkt_size=n' : set max packet size 'connect=0/1' : do a connect() on the UDP socket deprecated option: 'localport=n' : set the local port to n

if rtcpport isn't set the rtcp port will be the rtp port + 1 if local rtp port isn't set any available port will be used for the local rtp and rtcp ports if the local rtcp port is not set it will be the local rtp port + 1
