Real-Time Protocol.
The required syntax for an RTP URL is:
rtp://@var{hostname}[:@var{port}][?@var{option}=@var{val}...]
@var{port} specifies the RTP port to use.
The following URL options are supported:
@table @option
@item ttl=@var{n}
Set the TTL (Time-To-Leave) value (for multicast only).
@item rtcpport=@var{n}
Set the remote RTCP port to @var{n}.
@item localrtpport=@var{n}
Set the local RTP port to @var{n}.
@item localrtcpport=@var{n}'
Set the local RTCP port to @var{n}.
@item pkt_size=@var{n}
Set max packet size (in bytes) to @var{n}.
@item connect=0|1
Do a @code{connect()} on the UDP socket (if set to 1) or not (if set
to 0).
@item sources=@var{ip}[,@var{ip}]
List allowed source IP addresses.
@item block=@var{ip}[,@var{ip}]
List disallowed (blocked) source IP addresses.
@item write_to_source=0|1
Send packets to the source address of the latest received packet (if
set to 1) or to a default remote address (if set to 0).
@item localport=@var{n} (DEPRECATED)
Set the local port to @var{n}.
@end table
Important notes:
@enumerate
@item
if @option{rtcpport} is not set the RTCP port will be set to the RTP
port value plus 1.
@item
If @option{localport} (the local RTP port) is not set any available
port will be used for the local RTP and RTCP ports.
@item
If @option{localrtcpport} (the local RTCP port) is not set it will be
set to the the local RTP port value plus 1.
@end enumerate

RTSP is not technically a protocol handler in libavformat, it is a demuxer
