Question

Answer 1

从iOS7开始,您可以将AVPlayer isMuted属性设置为true.

在Objective C中,调用该属性muted.

Answer 2

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];

对于上面的 Swift 4 使 AVPlayer 视频静音

self.player.isMuted = true

Answer 4

SWIFT 2.0 和 SWIFT 3.0 （截至 2017 年 7 月 5 日）

对于那些对 Swift 感到好奇的人，它只是：

self.avPlayer.muted = true

实现目标-C 的最简单方法：

self.avPlayer.muted = true;
