スウィフトでGPUImageを使用してビデオを録画/保存する

Question

私は自分のビデオを録画するために「録画」ボタンを使用しています。ユーザーが「録画」ボタンを押したままにすると、録画したビデオを写真アルバムに保存したいと思います。私はUISaveVideoAtPathToSavedPhotosAlbum関数でちょっと固まっています。これまでのコード：

@IBAction func RecordAction(sender: UIButton) { 
    // User is holding down record button 
    if (!isRecording) { 
     do { 
      self.isRecording = true 
      let documentsDir = try NSFileManager.defaultManager().URLForDirectory(.DocumentDirectory, inDomain:.UserDomainMask, appropriateForURL:nil, create:true) 
      let fileURL = NSURL(string:"test.mp4", relativeToURL:documentsDir)! 
      do { 
       try NSFileManager.defaultManager().removeItemAtURL(fileURL) 
      } catch { 
      } 
      movieOutput = try MovieOutput(URL:fileURL, size:Size(width:400, height:645), liveVideo:true) 
      camera.audioEncodingTarget = movieOutput 
      filter --> movieOutput! 
      movieOutput!.startRecording() 
     } catch { 
      fatalError("Couldn't initialize movie, error: \(error)") 
     } 
    } 
} 

@IBAction func RecordDone(sender: UIButton) { 
    // After user stops holding down the button, save video to gallery 
    if isRecording == true { 
     movieOutput?.finishRecording { 
      self.isRecording = false 
      self.camera.audioEncodingTarget = nil 
      self.movieOutput = nil 
      UISaveVideoAtPathToSavedPhotosAlbum(pathToMovie, nil, nil, nil) 
     } 
    } 
} 

何か助けていただければ幸いです。

は、ビデオを保存するためにこれを使用してみてください：

func StartWritingvideo() 
{ 
    player.pause() 

    filters.removeAllObjects() 

    var paths: [AnyObject] = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true) 

    let filePath : String! 

    if trim == true 
    { 
     filePath = paths[0].stringByAppendingString("/output/outPut.mov") 
    } 
    else 
    { 
     filePath = paths[0].stringByAppendingString("/image.mov") 
    } 
    self.movieFile = GPUImageMovie(URL: NSURL(fileURLWithPath: filePath)) 
    self.movieFile.runBenchmark = true 
    self.movieFile.playAtActualSpeed = false 
    filters = [GPUImageAmatorkaFilter(),GPUImageMissEtikateFilter(),GPUImageSoftEleganceFilter(),FIIIN()] 

    let indexpaths = self.collectionView!.indexPathsForSelectedItems()! 
    let indexpath = indexpaths[0] as NSIndexPath 


    self.movieFile.addTarget(self.filters[indexpath.row] as! GPUImageInput) 
    let pathToMovie = paths[0].stringByAppendingPathComponent("IMG_filtered.MOV") 
    do 
    { 
     try NSFileManager.defaultManager().removeItemAtPath(pathToMovie) 
    } 
    catch 
    { 
     error as NSError 
    } 
    let Data = NSData(contentsOfURL: NSURL(fileURLWithPath: filePath)) 
    print(Data?.length) 
    let anAsset = AVAsset(URL: NSURL(fileURLWithPath: filePath)) 

    let videoAssetTrack = anAsset.tracksWithMediaType(AVMediaTypeVideo)[0] 
    var naturalSize = CGSize() 

    print(naturalSize) 
    naturalSize = videoAssetTrack.naturalSize 
    self.movieWriter = GPUImageMovieWriter(movieURL: NSURL(fileURLWithPath:pathToMovie), size: naturalSize) 
    let input = self.filters[indexpath.row] as! GPUImageOutput 
    input.addTarget(self.movieWriter) 
    self.movieWriter.shouldPassthroughAudio = true 
    if anAsset.tracksWithMediaType(AVMediaTypeAudio).count > 0 { 
     self.movieFile.audioEncodingTarget = self.movieWriter 
    } 
    else 
    { 
     self.movieFile.audioEncodingTarget = nil 
    } 

    self.movieFile.enableSynchronizedEncodingUsingMovieWriter(self.movieWriter) 
    self.movieWriter.startRecording() 
    self.movieFile.startProcessing() 
    self.movieWriter.completionBlock = 

    {() -> Void in 

     self.stop = false 
     self.movieWriter.finishRecording() 
     self.movieFile.cancelProcessing() 
     input.removeAllTargets() 
     self.movieFile.removeAllTargets() 


     if self.isLive == false 
     { 
      ALAssetsLibrary().writeVideoAtPathToSavedPhotosAlbum(NSURL(fileURLWithPath: pathToMovie), completionBlock: 
      {_ in 

       self.dismissViewControllerAnimated(false, completion: nil) 
       self.player.pause() 
      }) 
     }else { 


       self.dismissViewControllerAnimated(false, completion: nil) 

     } 

    } 


}
