I suspect that the problem is (somehow) related to your 'data source' implementation - i.e., your "FramedSource" subclass.</div>
<div><br></div><div>What happens when you don't just 'base' your server on "testOnDemandRTSPServer", but actually use the (original, unmodified) "testOnDemandRTSPServer" code? What happens when two clients request the same stream (from a file)? And do things change at all when you change your server to use a single input source for all concurrent clients - i.e., if you change line 29 of "testOnDemandRTSPServer.cpp" to</div>
