Iptv plugin uses VLC to transcode only the stream being currently
received so there really should not be any CPU power wasted on
transcoding inactive streams.

In other words a simple "video on demand" system should already be in
place. At least I can add multiple streams to the channel list and only
the active one is being transcoded. Have you experienced different behavior?

Of course if recording then VDR will keep the stream opened and iptv
plugin has to launch another instance of VLC to keep receiving two
streams at the same time.

BTW. we've actually been looking into adding support for receiving rtsp
streams and while it is more laborous than other protocols I think
implementing it would be entirely possible. Testing is a bit hard since
I'm not aware of suitable mpeg2 rtsp -stream providers. Are there any
publicly available?
