android – Mute audio on ExoPlayer

Posted by: admin April 23, 2020 Leave a comment

Questions:

I’m using Google new MediaPlayer named ExoPlayer and cannot find a way to mute the sound

Is there an easy way to mute audio track on Google ExoPlayer ? Or changing volume ?

How to&Answers:

Exoplayer 2.x.x

Get the current volume:
int currentvolume = player.getVolume();
Mute: player.setVolume(0f);
Unmute: player.setVolume(currentVolume);


Exoplayer 1.x.x

I found two ways to achieve it by editing DemoPlayer from ExoPlayer.

Good one :

Basicly, you need to get the audioTrackRenderer which is a ExoPlayerComponent and send message to it.
So :

  1. Add audioRenderer member and set it in onRenderers:

    // Complete preparation.  
    this.videoRenderer = renderers[TYPE_VIDEO];  
    this.audioRenderer = renderers[TYPE_AUDIO];  
    
  2. Add public method :

    public void setMute(boolean toMute){
        if(toMute){
            player.sendMessage(audioRenderer, MediaCodecAudioTrackRenderer.MSG_SET_VOLUME, 0f);
        } else {
            player.sendMessage(audioRenderer, MediaCodecAudioTrackRenderer.MSG_SET_VOLUME, 1f);
        }
    }
    

Usage :
mute : player.setMute(true);
unmute : player.setMute(false);

The other one :

This is not a good solution has the player will need to rebuffer when unmuting.
Consist of changing the audio track to an empty one:

// mute
player.selectTrack(FullPlayer.TYPE_AUDIO, ExoPlayer.TRACK_DISABLED);

// Unmute
player.selectTrack(FullPlayer.TYPE_AUDIO, ExoPlayer.TRACK_DEFAULT);

Answer:

The new way to mute and unmute volume as of version 2.3.1 can be done as follows:

int currentvolume = player.getVolume();

make sure to call the line above after starting the player otherwise you will get a nullpointerexception

to mute volume:

player.setVolume(0f);

to unmute volume:

player.setVolume(currentVolume);

Answer:

In ExoPlayer 2.x.x:

get the current volume:

int currentVolume = player..getAudioComponent().getVolume();

mute:

player.getAudioComponent().setVolume(0f);

unmute:

player.getAudioComponent().setVolume(currentVolume);

Answer:

try

player.setSelectedTrack(DemoPlayer.TYPE_AUDIO, DemoPlayer.TRACK_DISABLED);

analogous to this line of code

Answer:

Just simply use player.setVolume(0) will silent the video.

Answer:

I will recommend get the current volume first and then mute it. When you will unmute you can give user same volume.

float currentvolume;
currentvolume = player.getVolume();
player.setVolume(0.0f);
