iphone - iPhone 自定义媒体播放器

Question

我想创建一个 iphone 应用程序，它可以使用我自己的播放/暂停切换按钮和缓冲屏幕（或缓冲状态，然后我可以制作缓冲屏幕）播放在线广播流。任何建议或任何示例代码？

Answer 1

您可以像这样使用MPMoviePlayerController：

NSURL *mediaURL = [NSURL URLWithString:@"yourStraminglink"];
MPMoviePlayerController *streamingPlayer = [[MPMoviePlayerController alloc] initWithContentURL:mediaURL];
[streamingPlayer setControlStyle:MPMovieControlStyleFullscreen];
[streamingPlayer setMovieSourceType:MPMovieSourceTypeStreaming];
[self.view addSubview:[streamingPlayer view]];
[streamingPlayer prepareToPlay];
[streamingPlayer play];

并在后台播放音频会话：

AVAudioSession *audioSession = [AVAudioSession sharedInstance];
[audioSession setCategory:AVAudioSessionCategoryPlayback error:nil];
[audioSession setActive:YES error:nil];

您可以尝试使用此代码。

 - (void)startPlaying
{
   if (streamer)  
   {
           return;
   }

   [self stopPlaying];

   //radio channal url
   streamer = [[AudioStreamer alloc] initWithURL:cgf.streamURL];
  //NSLog(@"%@",cgf.streamURL);

   // Hard coded URL
   //NSURL *url = [NSURL URLWithString:@"http://www.freeproxyserver.ca/index.php?btxmnercdeqt=aHR0cDovLzE5OC41MC4xNTIuNzM6ODAwNC9yaHl0aG0%3D"];
   //streamer = [[AudioStreamer alloc] initWithURL:url];

      [[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(playbackStateChanged:) name:ASStatusChangedNotification
object:streamer];

    //play radio continuously when screen is locked
    UInt32 sessionCategory=kAudioSessionCategory_MediaPlayback;
    AudioSessionSetProperty(kAudioSessionProperty_AudioCategory, sizeof(sessionCategory), &sessionCategory);
    AudioSessionSetActive(true);

}
