I'm trying to get video thumbnails with the following code:
let asset = AVAsset(URL: url) let imageGenerator = AVAssetImageGenerator(asset: asset) imageGenerator.appliesPreferredTrackTransform = true do { let cgImage = try imgGenerator.copyCGImageAtTime(CMTimeMake(1, 30), actualTime: nil) let uiImage = UIImage(CGImage: cgImage) imageview.image = uiImage } catch let error as NSError { print("Image generation failed with error \(error)") } Sometimes it works and sometime it doesn't showing the following error:
Error Domain=AVFoundationErrorDomain Code=-11800 "The operation could not be completed" UserInfo={NSLocalizedDescription=The operation could not be completed, NSUnderlyingError=0x14eab520 {Error Domain=NSOSStatusErrorDomain Code=-12792 "(null)"}, NSLocalizedFailureReason=An unknown error occurred (-12792)}
I have tried to figure out what is Domain=NSOSStatusErrorDomain Code=-12792 but I don't understand how I can get more details about this error code. How can I convert this error code into a string to get relevant information about what this error means?
