Hi there,
We have a live event that goes out to almost 3000 people every Thursday at 12pm Central US time.
This is an all staff broadcast, and over the past 3 weeks there have always been issues at around the same time in the broadcast, where vmix turns from red to orange for between 10 and 40 seconds.
The interesting thing is it is always around the same time, and I have not seen it at any other time when streaming.
We send a H2.64 1.5mpbs 720p stream up to wowza streaming engine, and it is distributed from there.
Wowza support have found some errors in our setup which they are working on, but everything I have read about in terms of this issue points to a local hardware or internet speed issue. So I wanted to see if that could be the case. I cannot rule out the cause to be Wowza Streaming Engine, My Laptop, Vmix or my internet speed. I am not clear what the logs tell me, so looking at help to decipher the logs.
I have included the relevant parts of the log below to see if that helps.
Thanks in advance
