React Native: How to mute volume?

Question

How do you mute the volume in React Native (specifically for Android)?

I am using https://github.com/oney/react-native-webrtc but disabling the audio tracks for that doesn't seem to do anything, so I want to just mute the phone completely.

Answer 1

I used offerToReceiveAudio : false options to tell my PeerConnection that don't capture the audio track , in createOffer method .

For remote PeerConnection muting use this :

const pc = new RTCPeerConnection();
pc.createOffer({offerToReceiveVideo: true , offerToReceiveAudio: false}).then(sdpOffer=>{
    /// 
});

And use these params for the local media stream :

const mediaParams = {
    video : true ,
    audio : false ,
    options:{ muted : true }
};
getUserMedia(mediaParams, (error, stream) => {});

But I guess there's no certain way to mute the RTCView directly .

Answer 2

Inside the video tag use:

<Video ref={this.video} 
isMuted={true} 
source={{ uri: this.state.video_file }}/>.
Hope It would work.
