>You have to subscribe to each individually livestream_100 or
livestream_500, its 1-3 multiple streams at once requiring alot of upload
bandwidth ! Just like you said, I'd rather upload the maximum rate possible
, and then let the server degrade it on the fly somehow !
FME 3.0 can publish multiple streams to the FMS application. This will
require a good connection between the computer with FME and the FMS server.
You can upgrade this connection as needed, as opposed to upgrading the
connections of your viewers.
The viewer only subscribes the the appropriate stream, it does not subscribe
too all streams at once!
I find this feature very useful actually. Downsampling on the server side
would be very costly in terms of CPU and DELAY/LATENCY.
