Hi Christian,

The design of RTSP/1.0 is pretty close to that of HTTP/1.0, with very similar security and privacy considerations, but RTSP did not evolve as quickly as HTTP. In particular, I cannot find a profile for running RTSP over SSL or TLS in the RFC series. Is that defined elsewhere?

I don’t think so, but there is an updated version of RTSP 1.0 which is RTSP 2.0 and this is in the RFC editor’s queue ( RTSP 2.0 has support for TLS, actually it is MTI.

It is still in closed environments, such as cable networks, but much less on the public Internet.

Pure HTTP and Dynamic Adaptive Streaming over HTTP (DASH) is what is used across  the public Internet for video streaming by today.
