I work for Amino, if you want to know how the RTSP works... just ask :)
We're more than happy for people to come up with streaming solutions
that work with our boxes, especially free ones ;)
I'm not sitting in front of code at the moment, so I might be slightly
out, don't take this as gospel.
To that request above an NCube server would respond something like the
RTSP/1.0 200 OK
Then it would start throwing UDP data with TS packets at
126.96.36.199:11111. The ncube server is vaguely intelligent in that
if it gets an ICMP Port-Unreachable for the UDP packets, it'll assume
the client is not listening and send something like:
ANNOUNCE rtsp:/film1 RTSP/1.0
x-notice: 5401 "Downstream Failure" event-date=20030815T200723.897Z
Then drop the RTSP connection.
To change speed, to say trickplay at half speed:
SETUP rtsp:/film1 RTSP/1.0
Then, the server responds with:
RTSP/1.0 200 OK
So, what is the progress of RTSP (especially with trickplay support)
