Why stream has freeze when cpu is low

[Ceren Alptekin]

Hello,

Have a good day.

We are streaming with Antmedia with 2000 participants. CPU values look like below. But loading icon appears on the screen from at intervals. I added the image of the loading icon. Broadcast stops and then resumes after a certain time. We checked logs but there is no error log. Although there is no increase in CPU and memory, why is this case happening?

Best Regards.

Hi @Ceren Alptekin,

Hope you are doing well.

How are you sending the rtmp stream to the Ant Media Server?

If it's some encoder like OBS, can you please share the encoder settings that you are using?

P.S. You can refer to this document to tune the settings for rtmp to webrtc https://resources.antmedia.io/docs/rtmp-publishing-1

Let me know how it goes.

Hi @Ceren Alptekin,

How are you?

I tried to investigate this at my end but I'm not able to completely reproduce the issue.

If it is possible for you, can you please provide me Networking logs from inspect/developer tools.

Also, if it suits to you then you can mark your availability here https://calendly.com/antmedia and we can check these over a meeting.

Thank you
