Video goes black while the other side is uploading a file or switch background mode

[artavdalyan]

Platform and Browser:

Iphone 12 , Safari 14.4.2

SDK Version:

agora-rtc-sdk-ng : "^4.1.0",

To Reproduce

Steps to reproduce the behavior

1. Call the video through Safari to another device.
2. Upload document or switch background mode on Safari.
3. The other side video goes black.
4. We receive no action from Agora on Safari.

Additional context

When the other user has joined the call via Safari and wants to upload a document, the video goes black for the first user. We receive no action from Agora here. The flow is correct with other browsers.

so you will receive action callback for safari?

[artavdalyan]

I need to receive in order to show the corresponding screen.

So, is there a chance that you will send an action callback for mobile safari browser?

SDK can't send action when go to background.
For current status, you may need to rely on "user-left" event after 20 seconds, as remote client didn't send any data

But it is sending action to Android devices. Isn't it possible to do the same with IOS devices?
