问题 I am trying to play partially downloaded file (I want the audio to start when it has enough downloaded data).

I tested to see if the avplayer was playing by the first code snippet below and it prints out "Playing" which means the player is playing but no audio. I also tried setting the volume for avplayer and that didn't help. Don't understand why it won't play if anyone would like to help me out. Audio File URL: http://files

问题 I'm playing songs in AVPlayer . I have created a separate view controller for my media player and initialization, and all the methods that I'm using for the player (play, pause, repeat, shuffle) are there in the same view controller. I update a slider like this: [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(sliderUpdate:) userInfo:nil repeats:YES];` - (void) sliderUpdate:(id) sender{ int currentTime = (int)((song.player.currentTime.value)/song.player.currentTime

问题 I’m trying add inline videos to my UITableViewCells a la Instagram, Twitter, Vine…etc. I’m testing out the UI with a local video file using AVPlayerController and a custom cell (see sample code below). I wait for the status of the AVPlayer to be ReadyToPlay and then play the video.

This effect is made worse when there are multiple video

I connected the player Layer and it works fine. self.avPlayerLayer = [AVPlayerLayer playerLayerWithPlayer:[[PCPlayerManager sharedManager] audioPlayer]]; avPlayerLayer.videoGravity = AVLayerVideoGravityResizeAspect; avPlayerLayer.frame = CGRectMake(0, 0, videoView.frame.size.width, videoView.frame.size.height); [videoView.layer addSublayer:avPlayerLayer]; But how can I check if there is Video
