You can get the path to the document and pass it as a file URL into the MediaPlayer framework to get info about the video file. Here's code to get the duration in seconds of a movie file:
您可以获取文档的路径，并将其作为文件URL传递到MediaPlayer框架中，以获得关于视频文件的信息。以下代码以秒为单位获取电影文件的持续时间:
NSArray *docsPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsFolder = [docsPaths objectAtIndex:0];
NSString *movieFilePath = [documentsFolder stringByAppendingPathComponent:@"Movie.mov"];
MPMoviePlayerController *player = [[[MPMoviePlayerController alloc] initWithContentURL] autorelease];
NSTimeInterval duration = player.duration; // in seconds
