Adaptive rate

[LarsP]

I was wondering if it was possible to change the quality of a stream without restarting the session. By either using two different rate streams or transcoding.

At the moment I configure vlc with telnet as follows:

channel1 (high Quality file) : #duplicate{dst=display,dst=std{access=udp,mux=ts,dst=127.0.0.1:1234}}
channel2 (low Quality file): #duplicate{dst=display}

When the quality needs to be changed I access the telnet server via a socket. Then change the outputs of the streams. But it seems I need to restart the video so stop and start it again to. This introduces a second delay, which is too much for my purposes.

Anyone an idea on this one?

Thanks!
