影片开始，但与MPMoviePlayerViewController

Question

几秒钟后崩溃

我用它来播放视频的方法是：

-(void)playVideo:(NSString*)title { 

NSLog(@"NAME: %@", title); 
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *moviePath = [[paths objectAtIndex:0] stringByAppendingPathComponent:[NSString stringWithFormat:@"%@.mp4", title]]; 

MPMoviePlayerViewController *mp = [[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL fileURLWithPath:moviePath]]; 

mp.moviePlayer.scalingMode = MPMovieScalingModeAspectFit; 

[self presentMoviePlayerViewControllerAnimated:mp]; 

[mp release]; 
} 

约4秒或5秒的视频停止后，先前的屏幕显示和我得到以下错误：

_itemFailedToPlayToEnd: { 
AVPlayerItemFailedToPlayToEndTimeErrorKey = "Error Domain=AVFoundationErrorDomain Code=-11800 \"The operation could not be completed\" UserInfo=0xb19a220 {NSLocalizedDescription=The operation could not be completed, NSUnderlyingError=0xb17fac0 \"The operation couldn\U2019t be completed. (OSStatus error -12551.)\", NSLocalizedFailureReason=An unknown error occurred (-12551)}"; 

Answer 1

尝试简单的步骤：

第1步：进口MediaPlayer的框架 #import <MediaPlayer/MediaPlayer.h>

第2步：在.h文件中集委托 UIViewController<MPMediaPlayback>

第3步：

- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 
    NSBundle *bundle = [NSBundle mainBundle]; 
    NSString *fileLocation= [bundle pathForResource:@"file_video" ofType:@"m4v"]; 
    NSURL *vedioURL =[NSURL fileURLWithPath:fileLocation]; 
    MPMoviePlayerViewController *videoPlayerView = [[MPMoviePlayerViewController alloc] initWithContentURL:vedioURL]; 
    [self presentMoviePlayerViewControllerAnimated:videoPlayerView]; 
    [videoPlayerView.moviePlayer play]; 
} 

-(void)endSeeking 
{ 
    [self.navigationController popViewControllerAnimated:NO]; 
} 

-(void)stop 
{ 
    [self.navigationController popViewControllerAnimated:NO]; 
} 

Answer 2

试试这个代码一次：

-(void)playVideo 
{ 
MPMoviePlayerViewController *mp = [[MPMoviePlayerViewController alloc] initWithContentURL:VideoURL]]; 
] 
[self presentMoviePlayerViewControllerAnimated:mp]; 
[mp.moviePlayer play]; 
} 

，并确保那

1. 已包含MediaPlayer.framework
2. 进口的MediaPlayer/MediaPlayer.h文件在你的类
