I want to scan text page while call is going. What I do is, take frames from local video preview and send it to server for processing.
Before call starts, preview quality and resolution is highest. But when call starts resolution of capturer is decreasing. I can see that onFrameResolutionChanged event is called on local renderer. I'm guessing that Web RTC is changing resolution because of internet speed.
I don't want to change the local display resolution.
I have this issue on IOS and Android WebRTC library.
What can I do to prevent local camera preview resolution from decreasing?
I tried videoSource.adaptOutputFormat function, but it just sets maximum quality and by the time preview still decreases.
Update:
What was I searching was enableCpuOveruseDetection = false. It have be set in
val config = PeerConnection.RTCConfiguration(servers);
config.enableCpuOveruseDetection = false
This works good for android, It does not resize local preview quality.
But in IOS there is no enableCpuOveruseDetection in RTCConfiguration() class. So in IOS problem still remains.
