Your problem was including the “443” parameter.  This tells the client to attempt RTSP-over-HTTP tunneling on port 443.  This is probably not what you wanted, and it will not work (RTSP-over-HTTP tunneling does not work with TLS).

Instead, leave out that parameter, and just call:
	RTSPClient* rtspClient = ourRTSPClient::createNew(env, rtspURL, RTSP_CLIENT_VERBOSITY_LEVEL, progName);

Note that you don’t need to add this line if your RTSP URL begins with “rtsps://“ (instead of “rtsp://“), or if the RTSP URL specifies a port number of 322 (the port number reserved for RTSP over TLS).

Our existing RTSP client applications - “testRTSPClient” and “openRTSP” will work, provided that you give it a RTSP URL that begins with “rtsps://“, or specifies a port number of 322 - as noted above.  In this case, you should not need to modify any existing code.
