Mute audio on ExoPlayer

Question

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 ?

Cherida

player.volume = 0f – Hoenack

Answer 1

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);

Great solution! I was using "selectTrack" way but the video stream rebuffed every time I selected different audio track. – Durkheim

In ExoPlayer 2.5 you can do the track selection solution. "In ExoPlayer 2.5 this rebuffering has been eliminated, allowing audio and text track selections to be made in a seamless way." medium.com/google-exoplayer/… – Wallow

Is it possible for the ExoPlayer to play something at a volume that is independent from any system volume level? – Wherewith

@androiddeveloper I doubt that this is not an expected behavior for the User. As stated in the doc: Android uses separate audio streams for playing music, alarms, notifications, the incoming call ringer, system sounds, in-call volume, and DTMF tones. This allows users to control the volume of each stream independently. Plus: Unless your app is an alarm clock, you should play audio using the STREAM_MUSIC stream. Ref: developer.android.com/guide/topics/media-apps/… – Cherida

@HugoGresse Sometimes it's important to play a sound that the user will hear. I wanted to avoid changing global volume levels just for that. – Wherewith

probably worth another stackoverflow search like #4071649 – Cherida

There is a problem when an incoming call occurs, on some devices volume restores to default but ExoPlayer tells me volume is zero, which is false. github.com/google/ExoPlayer/issues/3923 – Invade

Answer 2

The new way to mute and unmute volume as of version 2.X.X 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 3

Easily you can do it with ExoPlayer:

Java Code:

float currentVolume = player.getVolume();
if (currentVolume == 0f) {
      player.setVolume(1f);
} else {
      player.setVolume(0f);
}

Kotlin Code:

val curentVol = player?.volume
if (curentVol == 0f) {
     player?.volume = 1f
} else {
     player?.volume = 0f
}

Answer 4

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 5

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);

Answer 6

try

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

analogous to this line of code

Bobwhite

which is exactly the same as player.selectTrack(FullPlayer.TYPE_AUDIO, -1); with ExoPlayer.TRACK_DEFAULT. This is totaly not a good solution as unmuting the sound will have major delay – Cherida

exactly the same but different. Anyway there are situations in which you want to completely disable the audio track (e.g. testing purpose) – Bobwhite

it's exactly my second case in the accepted answer 'The other one" – Cherida

Answer 7

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

Copolymerize

Answer 8

Returns the audio volume, with 0 being silence and 1 being unity gain (signal unchanged).

You should use new version: implementation 'com.google.android.exoplayer:exoplayer:2.18.5'

• Mute volume:

    exoPlayer.volume = 0f    

• Unmute volume value:

    exoPlayer.volume = 1f

Answer 9

Mute ExoPlayer using Kotlin

player.audioComponent?.volume = 0f
