[Live-devel] No RTSP session is currently in progress

[Ross Finlayson]

Because the error occurs with your custom application, it's difficult to say for sure, but most likely it's because your client is sending an operation (such as "PLAY") on a session, without having first sent a "SETUP".  (I'm not sure why your application worked before, though.)

To find out for sure what's going on, please change your application to pass 1 as the "verbosityLevel" parameter to the call to "RTSPClient::createNew()", rerun your application, and send us the diagnostic output (from 'stderr').

Note that the synchronous "RTSPClient" interface is now deprecated, and may be removed sometime in the future.  You should consider upgrading your application to use the asynchronous interface (I suggest using the "testRTSPClient" code as a model).
