有很多方法可以从视频中获取图像。其中一些是： -

NSURL *videoURL = [NSURL fileURLWithPath:url]; 

MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL:videoURL]; 

UIImage *thumbnail = [player thumbnailImageAtTime:1.0 timeOption:MPMovieTimeOptionNearestKeyFrame]; 

//Player autoplays audio on init 
[player stop]; 
[player release];
