无法在 AVPlayer 中播放 mp4 视频

Question

我正在使用 AVPlayer 播放视频。我无法播放 .mp4 videos.I 出现黑屏。这是我的代码。

`NSString *filePath = [self.videoArray objectAtIndex:index];
NSString *soundFilePath = [[NSBundle mainBundle] pathForResource:filePath ofType: @"mp4];
url = [[NSURL alloc] initFileURLWithPath: soundFilePath];
playerViewController = [[AVPlayerViewController alloc] init];
playerViewController.videoGravity = AVLayerVideoGravityResize;
playerViewController.view.frame = self.view.bounds;
playerViewController.showsPlaybackControls = NO;
video=[AVPlayer playerWithURL:url];
playerViewController.player = _video;
playerViewController.view.userInteractionEnabled = false;
[video play];
[self.view addSubview:playerViewController.view];`

Answer 1

尝试此代码，我认为它对您有用，因为您的 URL 似乎不适用于从网络捆绑它。

// your filepath which is may be "http" type
NSString *filePath = [self.video_Array objectAtIndex:index];
// http to NSURL using string filepath
NSURL *url= [[NSURL alloc] initWithString:filePath];
AVPlayerViewController *playerViewController = [[AVPlayerViewController alloc] init];
playerViewController.videoGravity = AVLayerVideoGravityResize;
playerViewController.view.frame = self.view.bounds;
playerViewController.showsPlaybackControls = NO;
video=[AVPlayer playerWithURL:url];
playerViewController.player = _video;
playerViewController.view.userInteractionEnabled = false;
[video play];
[self.view addSubview:playerViewController.view];
