Question

我需要使用“MPMoviePlayerViewController”播放视频，当我从库中选择一个视频并将其URL传递给播放器时，它播放约2秒钟并停止响应（根本没有交互），并在控制台中找到这些行< / p>

[MPAVController] Autoplay: Enabling autoplay

我已经尝试过“stackoverflow”中的所有内容，但没有用，任何人都可以向我推荐解决方案。

设备：iPad-3，版本：6.1

请建议

以下是我在播放视频时使用的代码

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    NSString* mediaType = [info objectForKey:UIImagePickerControllerMediaType];

    if([mediaType isEqualToString:(NSString*)kUTTypeMovie])
    {
        [self playVideoWithURL:[info objectForKey:UIImagePickerControllerMediaURL]];
    }
}


- (void)playVideoWithURL:(NSURL*)fileURL
{
    if(!self.playerViewController)
    {
        self.playerViewController = [[MPMoviePlayerViewController alloc] initWithContentURL:fileURL];
        [self.moviePlayerContainer addSubview:self.playerViewController.view];
        self.playerViewController.moviePlayer.scalingMode = MPMovieScalingModeNone;
        self.playerViewController.moviePlayer.movieSourceType = MPMovieSourceTypeFile;
        [self.playerViewController.moviePlayer stop];
    }
    else
    {
        self.playerViewController.moviePlayer.contentURL = fileURL;
    }

    CGRect movieFrame = self.moviePlayerContainer.frame;
    movieFrame.origin = CGPointZero;
    self.playerViewController.view.frame = movieFrame;
}

Answer 1

这种情况的发生仅仅是因为该电影不是本地存储的，而是试图通过iCloud逐步下载。

您的网络带宽（针对iCloud）无法应对该视频，因为其需求过高。

如果没有您的日志，您会看到如下行：

可能跟上或完全缓冲：0

这就像玩家的早期警告，告诉你它很可能不会足够快地加载数据以便流畅播放。

另一个重要的部分是这一行

[MPCloudAssetDownloadController]请求媒体的优先级料品ID：0

那个告诉你系统正在远程下载电影。它试图确保其他可能的并行下载应该等待这个，但显然没有足够的带宽（因为没有更多的可用）。

我担心，你无法直接做些什么。

您需要先从iCloud下载该视频，否则您需要降低其质量（重新编码）。
