How to force client to switch RTP transport from UDP to TCP?

Question

If the client wants to watch a stream that is on my RTSP server, it first tries to setup a stream through the UDP protocol. How can I tell it that my server only supports RT

Answer 1

To expand on the answer for android, For Android clients, they will always attempt to establish a UDP connection first.

For both OpenCore and StageFright I can confirm that if I return "461 Unsupported Transport" from my server in response to the first SETUP request for UDP transfer, both of these clients will then IMMEDIATELY attempt to establish a TCP based connection over the RTSP port.
