从iOS7开始,您可以将AVPlayer isMuted
属性设置为true
。
在Objective C中,该属性称为muted
。

这应该会看到你...
AVURLAsset *asset = [[avPlayer currentItem] asset];
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];
[[avPlayer currentItem] setAudioMix:audioZeroMix];

SWIFT 2.0和SWIFT 3.0 (截至2017年7月5日)
对于那些对Swift充满好奇的人来说,这只是:
self.avPlayer.muted = true
OBJECTIVE-C的最简单方法:
self.avPlayer.muted = true;
答案 3 :(得分:0)
您需要在视频处于播放状态时将false设置为false。
添加侦听器:
[itemPlayer addObserver:self
forKeyPath:kStatusKey
options:NSKeyValueObservingOptionInitial | NSKeyValueObservingOptionNew
context:@"AVPlayerStatus"];
代码:
-(void)observeValueForKeyPath:(NSString *)path ofObject:(id)object change:(NSDictionary *)change context:(void *)context {
if (context == @"AVPlayerStatus") {
AVPlayerStatus status = [[change objectForKey:NSKeyValueChangeNewKey] integerValue];
switch (status) {
case AVPlayerStatusReadyToPlay: {
if (isMuted) {
layerPlayer.player.muted = true;
}
}
default:
break;
}
}
}

要使上述Swift 4使AVPlayer视频静音
self.player.isMuted = true
答案 5 :(得分:0)
player.isMuted = true
对我不起作用。
就我而言,我需要视频永久静音。所以我用下面的代码实现了这一点。
self.player.volume = 0.0
