Tried to get DTMF sender from video sender

[Chris Hemingway]

Hi guys, pretty new to Ant Media, but seems to be working well for us so far. I've noticed these errors in the logs, what do they mean and is it something to be concerned about?

Thanks,

Chris

Hi,

Could you please share the errors you got?

No need to concern about this logs. Do you see any issue on streaming video?

 

 

[Chris Hemingway]

Not for the most part, but after about 2 hours the CPU usage, as seen on the Dashboard, goes up from around 70% to 100% and hangs around there. This causes the stream to fail and I get those entries in the log. What is odd though is that the CPU usage on the Azure VM is still showing around 70%. I thought it was to do with broadcasting @720p, but it did the same @360p.

I've doubled the VM, so the CPU runs at around 30% and will see how that goes.

Thanks for your help.

I have the same issue. High use of CPU and the same log errors.

Hi,

Got the same issue today, but also seeing odd spiking in Azure CPU usage every 6mins.

The logs look like it's trying to do adaptive streaming, but I don't have it active.

I'm also not sure why it lists HLS and webRTC connected viewers, as I don't have HLS active either.
