OpenVidu/WebRTC and iOS background processes

[carter...@nexxtgenit.com]

The details:

OpenVidu: 2.11.0

iOS: 13.3 / Xcode: 11.3

Android 10

Web:Chromium 79.0.3945.88

I am using the official OpenVidu Ionic tutorial. https://openvidu.io/docs/tutorials/openvidu-ionic/. I have not modified the source code.

The tutorial works wonderfully on all three platforms. 

But here is the problem, whenever my iOS app goes in the the background the webRTC communication is terminated. Not only that but when I monitor the server webhooks I am able to see a "webrtcConnectionDestroyed" event followed by a "participantLeft" event.

On Android the connection is maintained even when the app is in the background or the screen is locked. Obviously the video goes away but the audio persists (which is the behavior i desire).

So I have a few questions:

1) Is this the intended behavior?

2) If not is there anyway to maintain the webRTC connection when the app goes into the background?

Cheers,

Carter

Hello Carter, 

We have no control on what iOS and Android is doing with the app when it goes to background. The behavior you describe seems to be the standard behavior in both platforms. 

Maybe you can force to iOS to avoid "stopping" the application when it goes to background... but I don't know if it is possible at all. You know... Apple ;)

Best regards
