So far no luck. It works just fine for VLC but not for QuickTime. The problem seems to be that RR packets are not treated the same way: with VLC the noteClientLiveness method is called so the client session does not timeout. With QuickTime noteClientLiveness is not called so after a few seconds I get the message "RTSP client session (id "6F559A12", stream name "proxyStream") has timed out (due to inactivity)". Find attached both logs in verbose and debug mode. Any ideas?<br></div></div></blockquote><div><br></div></div>Hmm, you failed to mention that there are a lot of things different about your two client sessions - apart from just the media player application that they use. <div><br></div><div>You are apparently running VLC on the same computer (192.168.0.26) on which you're running the "LIVE555 Proxy Server". That's OK, but strange.</div><div><br></div><div>On the other hand, you are running QuickTime Player on a different computer: 192.168.0.28. That's also OK (and not strange :-). What *is* strange, however, is that QuickTime Player is requesting RTSP-over-HTTP streaming (using port 8000), even though it seems to be running on the same subnet as the proxy server, and therefore could probably just requested regular RTSP streaming instead.</div><div><br></div><div>The problem seems to be that - for some unknown reason (perhaps an incompatibility in the way that QuickTime Player implements RTSP-over-HTTP streaming?) - the QuickTime Player client is not sending periodic RTCP packets to indicate its liveness.</div><div><br></div><div>The quickest solution would be to stop your QuickTime Player client from requesting RTSP-over-HTTP streaming - something that it probably doesn't need to do.</div><div><br></div><div>Another solution (not recommended) would be to stop the proxy server from timing out clients due to inactivity. You can do that by setting the "reclamationTestSeconds" parameter to 0 in the calls to "RTSPServer::createNew()" in "proxyServer/live555ProxyServer.cpp". I.e., change the calls to</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>RTSPServer::createNew(*env, rtspServerPortNum, authDB);</div><div>to</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>RTSPServer::createNew(*env, rtspServerPortNum, authDB, 0);</div><div>(The disadvantage of this, however, is that TCP connections (and sockets) for clients that die without doing a RTSP "TEARDOWN" will stay around indefinitely, and eventually your proxy server will run out of sockets.)</div><div><br></div><div>The ideal solution would be fix whatever problem is causing QuickTime (when using RTSP-over-HTTP streaming) to apparently not send RTCP "RR" packets correctly. Unfortunately we can't help you with this; however, you should make sure that QuickTime is up-to-date on this computer (which looks like it's running Windows XP).</div><br><br><div apple-content-edited="true">
