Latencies / delay in live streams

Question

I'm doing some tests with FMS and live streaming, but I observe quite long delays.
When the stream is first accessed, the latency is around 3-5 seconds, which is acceptable.
But as we watch the stream for about 30 minutes or more, the latency grows to around 20 seconds, which is just too much.
What settings should I look at to keep the latency / delay minimal?

Answer 1

You're going to want to look at the bandwidth that you're pushing into your FMS system and the bandwidth you're getting out.  Usually when you see evolving live latency it's because there's a bandwidth bottleneck somewhere and you're dropping frames and falling behind as FMS attempts to deliver a stream that's too big for the destination.  If not then perhaps it's something else, but you'll want to eliminate that possibility first as it's the most common.
