ios MPMoviePlayerController can't play local files on simulator
提问by Robertas Uldukis
I'm new here. I'm already 2 days browsing for solutions, but unhappy.
我是新来的。我已经 2 天浏览解决方案了，但不满意。
Here is my code:
这是我的代码：
NSString *docPath = [NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *docaPathFull = [docPath stringByAppendingPathComponent:@"/IMG_0003.m4v"];
self.videoURL = [NSURL fileURLWithPath:docaPathFull];
MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL:videoURL];
UIImage *thumbnail = [player thumbnailImageAtTime:4.0 timeOption:MPMovieTimeOptionExact];
player = nil;
self.imageView.image = thumbnail;
Problem is, i can't make video file visible for MPMoviePlayerController. I can't get thumbnail and I can't play it, just black player and loading infinity.
问题是，我无法使 MPMoviePlayerController 的视频文件可见。我无法获得缩略图，也无法播放，只有黑色播放器和无限加载。
I did try:
我确实尝试过：
NSString*thePath=[[NSBundle mainBundle] pathForResource:@"IMG_0003" ofType:@"m4v"];
self.videoURLtheurl=[NSURL fileURLWithPath:thePath];
and this
和这个
self.videoURL = [[NSBundle mainBundle] URLForResource:@"IMG_0005" withExtension:@"mov"];
and this
和这个
NSString *filePath = @"/Users/[user]/Documents/video/IMG_0004.mov";
self.videoURL = [NSURL fileURLWithPath:filePath];
If you have any ideas how to save my life, please do!!!
如果您有任何想法如何挽救我的生命，请执行！！！

Actually this is my working example from my project. Make sure you added your m4v file to your project. The notification was a need for me, maybe it is not necessary for you.
实际上，这是我项目中的工作示例。确保将 m4v 文件添加到项目中。通知是我需要的，也许你不需要。
theMovie = [[MPMoviePlayerController alloc] initWithContentURL:
[NSURL fileURLWithPath: [[NSBundle mainBundle]
pathForResource:@"yourmovie" ofType:@"m4v"]]];
theMovie.view.frame = CGRectMake(0, 0, 320, 480);
[theMovie setControlStyle:MPMovieControlStyleNone];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(moviePlayBackDidFinish:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:theMovie];
[self.view addSubview:theMovie.view];
[theMovie play];

MPMoviePlayerControlleris Deprecated Now. So I have used AVPlayerViewController. and written the following code:
MPMoviePlayerController现在已弃用。所以我用过AVPlayerViewController。并编写了以下代码：
NSURL *videoURL = [NSURL fileURLWithPath:filePath];
//filePath may be from the Bundle or from the Saved file Directory, it is just the path for the video
AVPlayer *player = [AVPlayer playerWithURL:videoURL];
AVPlayerViewController *playerViewController = [AVPlayerViewController new];
playerViewController.player = player;
//[playerViewController.player play];//Used to Play On start
[self presentViewController:playerViewController animated:YES completion:nil];
Please do not forget to import following frameworks:
请不要忘记导入以下框架：
#import <AVFoundation/AVFoundation.h>
#import <AVKit/AVKit.h>
Hope this Helps..
希望这可以帮助..

You can use following method to get a thumbnail image for a given Video Url,
您可以使用以下方法获取给定视频网址的缩略图，
-(UIImage *) giveThumbofVideoUrl:(NSURL *) url{
NSString *urlString = [url absoluteString];
AVAsset *asset = [AVAsset assetWithURL:url];
AVAssetImageGenerator *imageGenerator = [[AVAssetImageGenerator alloc]initWithAsset:asset];
imageGenerator.appliesPreferredTrackTransform = YES;
//imageGenerator.maximumSize = CGSizeMake(320,480);
CMTime time = CMTimeMake(1, 1);
CGImageRef imageRef = [imageGenerator copyCGImageAtTime:time actualTime:NULL error:NULL];
UIImage *image = [UIImage imageWithCGImage:imageRef];
CGImageRelease(imageRef);
return image;
}
How you can use it ?,
你如何使用它？，
NSString*thePath=[[NSBundle mainBundle] pathForResource:@"IMG_0003" ofType:@"m4v"];
NSURL *movieUrl=[NSURL fileURLWithPath:thePath];
UIImage *thumbnail = [self giveThumbofVideoUrl:movieUrl];
