[Opensim-dev] OpenSim Hardware Requeriments

Thu Feb 19 06:15:12 UTC 2009

I always had that on my list to try this, but didn't try it yet :-).

As far as I understood you should be able to divide your region in parcels. Each parcel can have a different media stream.  So what I wanted to try was to divide one big conference room into N parcels each with a media stream of the participant.  This should work with N = not too high :-).

But I don't know if the client can display multiple streams, or whether it just plays the stream of the very parcel you stand in.

Indeed I would expect that
- the number of concurrent streams is limited by the clients connection
- the client probably will have problems displaying more than say 3 streams (wild guess)

Just open several streams in a browser and you will find the practical limit.

Thanks Dirk. But how does one do multiple simultaneous streams cause the
media url can point to only one address? Also, would multiple simultaneous
streams slow down the client?
