使用 MPMoviePlayerViewController 视频开始播放但几秒钟后崩溃答案

【问题标题】：Videos start but crash after a few seconds with MPMoviePlayerViewController使用 MPMoviePlayerViewController 视频开始播放但几秒钟后崩溃

【问题描述】：

我用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];
}

视频停止大约 4 或 5 秒后，显示前一个屏幕，我收到以下错误：

_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)}";

原来我尝试播放的视频已损坏，下次我会先检查一下。

【解决方案1】：

尝试简单的步骤：

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

第 2 步： 在 .h 文件中设置委托 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];
}

【解决方案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

您已包含 MediaPlayer.framework
在您的班级中导入了 MediaPlayer/MediaPlayer.h 文件
