Getting a thumbnail from a video url or data in iOS

Question

I am trying to acquire a thumbnail (of the first frame) from a video taken from iphone 3GS camera so I can display it. How to do this?

Answer 1

-(UIImage *)generateThumbImage : (NSString *)filepath {     NSURL *url = [NSURL fileURLWithPath:filepath];      AVAsset *asset = [AVAsset assetWithURL:url];     AVAssetImageGenerator *imageGenerator = [[AVAssetImageGenerator alloc]initWithAsset:asset];     imageGenerator.appliesPreferredTrackTransform = YES;     CMTime time = [asset duration];     time.value = 0;     CGImageRef imageRef = [imageGenerator copyCGImageAtTime:time actualTime:NULL error:NULL];     UIImage *thumbnail = [UIImage imageWithCGImage:imageRef];     CGImageRelease(imageRef);  // CGImageRef won't be released by ARC      return thumbnail; } 

you can get the frame using the time.value suppose you want to 1 second frame then use the

time.value = 1000 //Time in milliseconds
