[Live-devel] [Mirasys] Live555 RTSP server questions

[Victor Vitkovskiy]

Hello Ross, 

Thank you for your answers. 
Related to HTTPS support - I have found this method for RTSP server - setTLSState where we need to specify certificate and private keys. 
So, this is not related to HTTPS or this is not working currently? 

Best regards,

Yes.  By default, a RTSP server will support RTP-over-UDP, and RTP-over-RTSP(TCP).  However, if you call
        setUpTunnelingOverHTTP()
(with a non-zero port number) on your “RTSPServer” object - as is done in the “testOnDemandRTSPServer” and “live555MediaServer” applications - then it will also support RTP-over-HTTP(TCP) .

Also, if you call
        disableStreamingRTPOverTCP()
on your “RTSPServer” object, it will not support RTP-over-RTSP(TCP) streams, nor RTP-over-HTTP(TCP) streams.  I.e., it will support RTP-over-UDP only.

In summary, if you want to support only RTP-over-UDP, then call
        disableStreamingRTPOverTCP()

(Note that there is no way to tell your server that to accept *only* RTP-over-TCP (RTSP or HTTP).   Nor will there ever be; RTP-over-TCP is generally discouraged.)


> Also, it is possible to tunnel RTSP session over HTTP / HTTPS, but seems that this can work only in addition for non-HTTP/HTTPS server and we can't host only HTTP / HTTPS, is that true?

I’m not sure I understand this question - but we currently support RTP-over-HTTP in both our client and our server implementation.  However, we currently do not support RTP-over-HTTPS  (for either our client or server), although it’s likely that we will support this sometime in the future.
