React-native-webrtc: Video chat volume is too low

[tiensonqin]

First of all, great job, without this component I won't release my app.

Anyone experience this on iphone?
Some of my users told me that they can't hear me, the volume is too low.

My app is on the app store,
https://itunes.apple.com/us/app/lym/id1134985541?ls=1&mt=8
So really need to fix this bug,
RN && webrtc newbie, could anyone help me?

oops, I am experiencing it on Android, iOS works great though.

on android, the default threshold may differ by devices, so you may want to control it according your experiences.

on ios, they officially recommended to implement MPVolumeView

I'm not sure if it is related to webrtc itself, but you try checking/increasing volume to see if it back to normal

@zxcpoiu Me, too. I only got low volume problem on Android. iOS goes well.

@zxcpoiu @oney sorry for the late response,
setForceSpeakerphoneOn works for me on IOS.

(.setForceSpeakerphoneOn incall-manager true)

I think this issue should be renamed: "Use speakerphone by default instead of ear speaker".

Should we advise using setForceSpeakerphoneOn from the react-native-incall-manager module? Or should we implement this directly in react-native-webrtc?

On iOS, this can be implemented with AVAudioSessionModeVideoChat and on Android with setSpeakerphoneOn.

We had discussed this a little bit before and guess maybe it is better to make this library agnostic.
Because there are tons of use cases, some may have it's own logic to audio/video routes or different implementation when to screen on/off and proximity and so on.

given that the complexity to maintain audio/video/screen/locker/proximity, we decide to split these logic in different repository. that's the reason why react-native-incall-manager was born.

I think the best place to have this utils is, for example, RCTWebRTCDemo, which we can implement some simple utils like you described above, or an example how to integrate with react-native-incall-manager for different use cases.

my two cents
