Webrtc card doesn't always stop/disconnect stream

Open Brumhilde opened this issue 11 months ago • 11 comments

The battery of my Aqara G4 doorbell drained over night after setting up webrtc card.

Home assistant and go2rtc are running in containers on same host.

HA Core version 2024.6.4 WebRTC v3.6.0

go2rtc config:

You can check active streams in the go2rtc WebUI.

AlexxIT avatar Dec 04 '24 07:12 AlexxIT

Yes, the stream was still active after I closed the HA tab with webrtc card. I checked both streams tab and network tab and it was active.

EDIT: Streams and network tabs in go2rtc webui

Brumhilde avatar Dec 04 '24 07:12 Brumhilde

Show stream info

AlexxIT avatar Dec 04 '24 07:12 AlexxIT

I will reproduce and get that for you when I'm back home. Thanks!

Last night I made sure that last print in log was "[rtsp] disconnect" and the doorbell did not drain battery.

Also, when I reproduced it twice yesterday it was solved by restarting go2rtc the first time but the second time go2rtc started the stream directly after restart. The second time it was solved by restarting HA.

Restarted go2rtc and stream is closed.

@AlexxIT I'm experiencing the same issue, this is a serious issue because for battery-powered devices this would lead to battery quickly running out of charge

Suxsem avatar Jan 09 '25 10:01 Suxsem

@AlexxIT I noticed that ws server is instantiated with autoping and autoclose set to false; furthermore no heartbeat is configured. https://github.com/AlexxIT/WebRTC/blob/60ea122871566b0395ace7227c090fa05541c15d/custom_components/webrtc/init.py#L259 How exactly is the ws sessions closed?

Suxsem avatar Jan 09 '25 17:01 Suxsem

You're looking at a part of the code that doesn't relate to the problem at all.

AlexxIT avatar Jan 09 '25 18:01 AlexxIT

Same here. I guess this issue comes from go2rtc, not the WebRTC Camera.

I found that when I closed the WebRTC Camera, my whep source did not stop the connection. I repeatedly opened and closed the HA page and noticed that the data bandwidth kept increasing. As far as I know, WebRTC should trigger a failed event if the client goes down, but it didn’t after we closed the player. It seems that connection peers are not being properly released on the go2rtc side, causing unnecessary network traffic.

Yep, I am also getting the same issue.
