I need to build a server for a website that will stream live audio and video. The functionality will be like www.ustream.tv with channels with one broadcaster and unlimited subscribers (who can only chat via text). The stream will have several bit-rates depending on the connection. For start I need to be able to have 100 broadcasting users with 1000 subscribers.
Which is the best software and hardware combination? I'll start with one server for start and then I'll build more if needed.
I've heard about media servers based on flash media server 3.5 or Red5. But I dont know which one to prefer.
Thanks in advance (and sorry for my English)
