AVPlayer Volume Control

Question

I want to create a button that mutes the audio from an AVPlayer.

Why can´t I use .volume with AVPlayer, only with AVAudioPlayer? Is there another way to change the v

Check out this link

apple documentation for muting audio

Below is the code

 AVURLAsset *asset = [AVURLAsset URLAssetWithURL:[self myAssetURL] options:nil];
NSArray *audioTracks = [asset tracksWithMediaType:AVMediaTypeAudio];

// Mute all the audio tracks
NSMutableArray *allAudioParams = [NSMutableArray array];
for (AVAssetTrack *track in audioTracks) {
    AVMutableAudioMixInputParameters *audioInputParams =[AVMutableAudioMixInputParameters audioMixInputParameters];
    [audioInputParams setVolume:0.0 atTime:kCMTimeZero];
    [audioInputParams setTrackID:[track trackID]];
    [allAudioParams addObject:audioInputParams];
}
AVMutableAudioMix *audioZeroMix = [AVMutableAudioMix audioMix];
[audioZeroMix setInputParameters:allAudioParams];

// Create a player item
AVPlayerItem *playerItem = [AVPlayerItem playerItemWithAsset:asset];
[playerItem setAudioMix:audioZeroMix]; // Mute the player item

// Create a new Player, and set the player to use the player item
// with the muted audio mix
AVPlayer *player = [AVPlayer playerWithPlayerItem:playerItem];

// assign player object to an instance variable
self.mPlayer = player;

// play the muted audio
[mPlayer play];
