Issue: Occurs when i export the video. The rotation/transform seems to be taken in to consideration only when a filter from the SCSwipeableFilter is applied. "emptyFilter" doesnt change the preffered transform.
I set the the rotation transform both to AVMutableCompositionTrack, and AVMutableVideoCompositionLayerInstruction.
Reproduce:
// Exporting code
self.mutableComposition.tracksWithMediaType(AVMediaTypeVideo)[0].preferredTransform = self.storedPrefferedTransform
let playerItem = AVPlayerItem(asset: self.mutableComposition)
exportSession = SCAssetExportSession(asset: playerItem.asset )
if let currentFilter = self.videoDisplay.selectedFilter?.copy() as? SCFilter{
exportSession.videoConfiguration.filter = currentFilter
}
let documentsPath = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0] as NSString
let formatter = NSDateFormatter()
formatter.dateFormat = "yyyy'-'MM'-'dd'T'HH':'mm':'ss'Z'"
let date = NSDate()
let outputPath = "\(documentsPath)/\(formatter.stringFromDate(date)).mp4"
let outputURL = NSURL(fileURLWithPath: outputPath)
exportSession.videoConfiguration.preset = SCPresetHighestQuality
exportSession.audioConfiguration.preset = SCPresetHighestQuality
exportSession.videoConfiguration.affineTransform = self.storedPrefferedTransform
exportSession.videoConfiguration.keepInputAffineTransform = false
exportSession.videoConfiguration.maxFrameRate = 35
exportSession.outputFileType = AVFileTypeMPEG4
exportSession.outputUrl = outputURL
exportSession.delegate = self
exportSession.contextType = .Auto
exportSession.exportAsynchronouslyWithCompletionHandler({
