Hi Ross,
As per your suggestion, in RTSPServer class, I need to pass the TLS socket
number to RTSPServer constructor.
I am using OpenSSL for creating TLS socket. When I create TLS socket, it
returns SSL type object. How can I pass that SSL type object to RTSPServer
constructor?
I have attached sample code for creating TLS socket using OpenSSL.
Regards,
Gaurav Badhan
