AVAssetImageGenerator provides images rotated

Question

When obtaining a UIImage of a video via AVAssetImageGenerator, I\'m getting back images rotated (well, technically they\'re not) when the video is shot in portrait orientati

Answer 1

Here is the solution in swift version 4:

func thumbnailImageForFileUrl(_ fileUrl: URL) -> UIImage? {
    let asset = AVAsset(url: fileUrl)
    let imageGenerator = AVAssetImageGenerator(asset: asset)
    imageGenerator.appliesPreferredTrackTransform = true

    do {

        let thumbnailCGImage = try imageGenerator.copyCGImage(at: CMTimeMake(1, 60), actualTime: nil)
        return UIImage(cgImage: thumbnailCGImage)

    } catch let err {
        print(err)
    }

    return nil
}
