Laggy stream with WebRTC and adaptive streaming enabled

[radosdaniel]

Hey,

When I turn on adaptive streaming, and stream with WebRTC (using the test WebRTCApp) the stream gets very laggy compared to streaming with adaptive streaming off.
We tested it on a brand new instance on AWS, all default configurations.

On an other server we tried several configurations, but nothing helped.
Streaming with RTMP works fine, but WebRTC is very important for our product.

Thanks for your help!

Are you just testing with one live stream and what server are you using?

Does it look like system resources are getting really high with adaptive bitrates enabled? Typically, as soon as you start using ABR, the system resources do increase and an increase in resources.

Hi guys,
Thank you for your answer @yashtandon113. I think @radosdaniel question is more likely about license transferring. Please correct me if I'm wrong @radosdaniel

Just let me explain it further.

• If you just use AMS GPU from AWS Marketplace, it has its own license no need to transfer any license. You can stop your previous instance or cancel your subscription to antmedia.io if you have a license from antmedia.io

• If you have a license from antmedia.io and would like to use it on an AWS GPU instance, you need to install Ant Media Server to a GPU instance and use the license directly. No need for any transfer because your license is floating and can be used anywhere.
  If you have difficulty with installation, let us know. We can help you with the installation

Please let us know if we can do anything to help and proceed.

Cheers

@mekya we have a FD99739 with same issue from same customer with same issue on GPU instance. Did you manage to find recommended parametres?

[mekya]

Generally, there is no problem for GPU instance in this case. The problem is that CPU is not powerful to encoder in real-time and when we use GPU, it's working well. I think the problem is something else in that ticket.

@mekya I found the customer application setting encoderPreset: slower. I think this is the issue. I changed this preset and tried various combinations on the OBS settings to achieve a better quality of playback. #5464 (comment)
