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.<br>

On Linux, see `man slattach` and

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