NSURL *movieURL = [NSURL fileURLWithPath:moviePath];
moviePlayer=[[MPMoviePlayerController alloc] initWithContentURL:movieURL];
moviePlayer.useApplicationAudioSession=NO;
[[moviePlayer view] setFrame: CGRectMake(30,70,385,225)];
[self.view addSubview:moviePlayer.view];
[moviePlayer setContentURL:movieURL];
moviePlayer.shouldAutoplay=NO;
}
请帮忙。为什么我没有得到输出。
谢谢， 萨钦

我是OpenEars开发人员。您不能与PocketsphinxController同时使用AVPlayer，MPMoviePlayer或MPMusicPlayerController。您应该能够使用它们，停止它们，释放它们，然后使用AudioSessionManager重置音频会话设置，然后然后实例化并启动PocketsphinxController。据我所知，低延迟音频单元驱动程序所需的太多音频会话设置被AVPlayer，MPMoviePlayer和MPMusicPlayerController对象自动覆盖，并且不允许它们被AudioSessionManager重新覆盖。对象仍然在使用（这似乎意味着：仍然实例化）。这不是AVAudioPlayer的问题。
很多人目前正在OpenEars forums讨论这个问题，我现在处于初步阶段，找出可能做些什么，所以也许你想过来添加你的数据，所以我可以确保我可以在文档中提供有关此问题的正确指导和/或可能发现变通方法或基础错误。
编辑：我已经找到了一个让这个问题变得不那么强大的问题，我刚刚发布了包含修复功能的.912。现在不需要释放媒体播放器对象，它应该足以停止播放并再次运行[audioSessionManager startAudioSession]并且（仅当它被中断时，在每种情况下都不需要）重启PocketsphinxController监听循环
