Identify why WebRTC stream stops after a few seconds

[xiki808]

I have two IP cameras and both streams are configured. I have no problems with one, but with the other, the webrtc stream freezes after just a few seconds. Is it possible to point out if a camera has some settings that might break the webrtc stream?

tru ffprobe to source

[xiki808]

Sorry but I know so much, how can I do that?

[deepch]

it you camera stream rtsp://10.0.0.101:554/onvif1

10.0.0.101 - camera? or server ?

[deepch]

In general, these errors say that your stream is broken.

1) Update camera firmware 2) Try resetting the camera to default settings

[xiki808]

10.0.0.101 is the camera's IP

Firmware is updated, will try resetting

[deepch]

It's definitely a problem with the camera.

[xiki808]

Thanks a lot gave it a reset and it worked fine now!

If there's any possible way with ffmpeg to figure out if a camera has issues with webrtc, I would like to know, to use some kind of validation in my scripts which is setting things up

[xiki808]

because if could have used hlsll as that was working fine
