We have "video-replated" app and using writeVideoAtPathToSavedPhotosAlbum:completionBlock: from ALAssetsLibrary to save videos into camera roll. Most of the time it works very well, but sometimes completionBlock:^(NSURL *assetURL, NSError *error) called with BOTH parameters equal to nil.
Documentation states that in case error is nil - no error occurred during write operation, so assetURL should not be nil. But still we get assetURL == nil and error == nil at the same time, sometimes
In what cases this is possible? Any help welcome.
