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:
