SirFrigglesworth, what medium are you intending to stream video with? Are you going to use Flash to broadcast the video from source or something else?
I would say...
If your looking for something technical related to video (like the various formats), use computer hardware and software.
If it's about implementing it on a website (such as using Flash) use the appropriate forum for the language being used.
If it's about the delivery side of things (server to end user or resource usage) then place it in the hosting section.
PS: We have some general development / web design forums which can fit the stuff which doesn't fit elsewhere
