<div>Hi All,</div>
<div> </div>
<div>We've tried to use Live555 media server (win32) with various max packet size configurations (we've compiled the server with each change) with an MPEG2 transport stream we've received from a customer over a WAN, and while the same configurations worked flawlessly in a LAN environment, sniffing the RTP stream delivered over a WAN (over ATM + NAT router) with ethereal discovered a lot of lost packets (and as a result - degradation in picture quality, artefacts and smearing where motion occurred).
</div>
<div>We've tried different files with various bitrates, so I am pretty much sure bandwidth is not the issue.</div>
<div>The RTP transport was delivered over TCP, and we've used VLC as the client application.</div>
<div>We've tried the default max packet size, and the following: 1400, 1300, 1350, 1340, 1330 bytes per packet (not including overhead). Interesting is that the stream would not play when max packet size was set below 1330.
</div>
<div> </div>
<div>Could anyone refer me to any resource which would help me to solve the problem? Searching google didn't produce any helpful results, and since we are not experts on RTSP/RTP/MPEG2-TS, digging into the source code didn't help much either...
</div>
<div> </div>
<div>Many thanks,</div>
<div>Ilya</div>
