First frame of a video using AVFoundation

Question

I\'m trying to get the first frame of a video using the classes in AVFoundation. But it appears to not be getting an image at all.

My code currently looks like this

Answer 1

I used null0pointer solution but in some videos I recieved the first frame rotated. To resolve this issue I set to TRUE the appliesPreferredTrackTransform property of AVAssetImageGenerator. And this code looks like this:

AVURLAsset* asset = [AVURLAsset URLAssetWithURL:fileURL options:nil];
AVAssetImageGenerator* imageGenerator = [AVAssetImageGenerator assetImageGeneratorWithAsset:asset];
[imageGenerator setAppliesPreferredTrackTransform:TRUE];
UIImage* image = [UIImage imageWithCGImage:[imageGenerator copyCGImageAtTime:CMTimeMake(0, 1) actualTime:nil error:nil]];
[self.imageView setImage:image];
