Tx, I've been away for a while, see if I can pick this up again.

The given setup is this: I have a video server and an rstp server. Clients
request a particular video stream from the rtsp server. The rtsp server
then request that stream from the video server and sends incoming frames to
the client. There's also a controller application. This application gets
information from the rtsp server and uses that to instruct the client
application to get particular video. If the client should not retrieve
video anymore, the controller instructs the client for that. If the
controller can not reach the client to stop streaming it needs to tell the
server to stop streaming. Although this is not normal usage it is very
important that the video stream is stopped.

It's easy to stop the stream, but it would be nice to close the connection
also.
