Live wirecast to AWS streams fine to some but others get dropped every 5 seconds
We had a very successful live stream to 150 unique viewers on
stagedive.com using the Wowza EC2 AMI instance on Amazon AWS. However we had reports of the stream stopping every 5 seconds for some viewers with the player error of "livestream" not found.
We are confident that some people were able to watch the entire stream without any errors or disconnection. We had a couple of testers verify this. This most likely eliminates live up bandwidth from our local wirecast or any local origin problems. So it seems the feed was getting out fine to Amazon.
The wowza is set up to stream RTMP to flash and repeat for iOS devices. Both were tested and received the feed just fine.
But what happened to the people who got dropped every 5 seconds?
Below is Wowza log from the show that night. Does anyone know where to look for the cause of these errors? The log shows that some people were disconnected and that the streams were stopped. Why? Can anyone tell me how to troubleshoot and find logs to figure out this error.
The small, large and xlarge are known to get about 150, 250 and 350mbs throughput, resp.
You also have a lot incoming streams. I think that is as likely to be the issue. The small should handle 150 1mbs streams just barely. One way or the other, I think the issue was maxed out capacity. A small is not big.
We don't have numbers on the other instance types at this time.
I misread the upstream part. You said you were "pushing less than 1000k up", which is reasonable as far as the EC2 instance is concerned. It could be a lot for the encoder location. There is a UpBWCheck app here:
You also said "150 uniques" which I took to mean 150 concurrent, which is what really matters. If you were at or about 150 concurrent 1mbs streams, you were capping out. In that case what you described makes sense, expected.
