WebRTC stream freezes

[vuminhkh]

Hello,

I'm writing a react native app using react-native-webrtc to communicate with go2rtc via frigate and home assistant. It works great in webrtc mode on my Tapo C210, Hikvision doorbell, but on my Annke FCD600 cameras with high resolution 3632 x 1632 in H264, the video stream freezes every seconds or even don't start at all (in debug log the stream receive mute event frequently and takes really long time to establish the connection, the bi directional audio stream is ok). If I reduces the bit rate drastically, then it works a little bit better but it still freezes from time to time, in night mode it freezes less than day mode. In the same time on all other cameras, it works great, if you guys have an idea how to debug this, I'll be very thankful. Basically, if i'm not mistaken Annke is just Hikvision rebranded, so I'm not sure what can be different between my Annke stream and Hikvision doorbell streams. I'm using go2rtc 1.8.5. Thank you in advance for your help.

The hikvision doorbell's video in 1920x1080 also freezes from time to time.

It depends if you using WebRTC inside or outside your home network.

I have the same problem inside or outside my network. I checked the stream configuration when i'm inside my network, it's IP v6 UDP which is used. Anyway with Tapo C210 (2304 x 1296), I have the best streaming experience, never freezes inside or outside. For the moment, for my Annke cameras, I get the video stream from home assistant in HLS mode (with 3, 4 seconds lag but no freezing) and audio + microphone stream via WebRTC as a work around. I really wish to be able to use WebRTC though but I don't know how to optimize to avoid freezing.

Have you read recommendations?

Thanks, I prefix the rtsp stream with ffmpeg, it's still 'glitchy'

I don't know how yet, but frigate on safari on my phone works better than react-native-webrtc. It's perhaps the library which has issues, but I still don't know why the tapo stream works well with react-native-webrtc but not the annke streams.

but in the same time, it's glitchy both on ios and android.

Have you tried very glitchy version?
