Ios GPUImage2-如何获取已处理的视频URL以保存在设备中？

在应用视频过滤器后，是否有人可以帮助我从GPUImage2库中获取已处理的视频URL

do {
    let bundleURL = Bundle.main.resourceURL!
    let movieURL = URL(string:"sample_iPod.m4v", relativeTo:bundleURL)!
    movie = try MovieInput(url:movieURL, playAtActualSpeed:true)
    filter = SaturationAdjustment()
    movie --> filter --> renderView
    movie.start()
} catch {
    fatalError("Could not initialize rendering pipeline: \(error)")
}

提前感谢,， 詹姆斯

用法示例

  applyFilters()

  DispatchQueue.main.asyncAfter(deadline:.now()+AVAsset(url:inputVideoUrl).duration.seconds, execute: {
       stopVideoRecording{
            self.saveVideo()
       }
  })

获取URL的原因是将其保存在我们的设备中。请帮忙

  applyFilters()

  DispatchQueue.main.asyncAfter(deadline:.now()+AVAsset(url:inputVideoUrl).duration.seconds, execute: {
       stopVideoRecording{
            self.saveVideo()
       }
  })
