I want to to send RTP packets (RTP header + payload after
packetization) to a serial port.
From my experience with Live I figure that using socket_pair will be a
good solution.
In that way I will be able to use the current code to send the data
into the socket, and on the other side I will write some listener that
will recv from the socket and transmit it using the serial port.
Just a random thought, which might save you having to have this
IP-to-serial conversion process... I don't know whether you've got
control of the other end of the serial line, but could you not just set
up a SLIP interface and send the RTP over that? The Live555 code would
just see it as a normal IP interface. You'd need to do this at both
ends, but you could then have a standard UDP socket listener at the
receiver end to receive the RTP packets.
On Linux, see `man slattach` and

Even if you couldn't do this at the remote end, SLIP is a really simple
protocol which you could implement yourself - see:
