Hello everyone,

My next question. . .

I have 12 Streams which I can successfully stream, with little problem .. They take 240meg/sec of BW .. but it work s.. and CPU usage is rather low ..

So .. My Problem ..

I need to take those 12 feeds , put them into a mosaic , and re-encode them at a lower rate, and stream them out ..

So .. my problem: .. CPU

The way I have it setup .. and i'll post an example, the system (3.1Ghz .) can only handle encoding two HD streams ... I would need a rather large machine to handle 12 ...


I'm thinking I might be doing it wrong ... Isn't here a way to Transcode just the mosaic, instead of transcoding each stream into the mosaic ..

Here is an example of my setup using 7 streams ...( I can only run two - 3 of theses at a time to having it actually work and the CPU not hit 200%)
