Yes; however RFC 7826 is the specification for “RTSP version 2.0”, which we do not implement.  (Nor, to my knowledge, does almost anyone else.)

We implement RTSP version 1.0, as described in RFC 2326.  This does not specify “RTP over independent TCP connections”, so we do not implement this.

Note that our RTSP server implementation allows clients to omit the "interleaving=“ field, without returning an error (see “RTSPServer.cpp”, line 1600).  This was to accommodate a buggy version of QuickTime Player (several years ago).
