[Live-devel] QuickTime and RTCP RR packets.

[Bob Bischan]

I wanted to pass on some additional information and findings on this topic.

With RTSP-over-HTTP It appears that If you provide a timeout value..ie
"timeout=60" in the SETUP Response, the QuickTime player will send OPTIONS
requests back to RTSPServer to indicate it's liveness.

Before modifying RTSPServer.cpp to provide this timeout value I was having
the same problems as described in this thread. With this change the
QuickTime player does not timeout anymore!

The best option is for Apple to fix their bug, but this may be a work
around for those that want to use Quicktime.
