Can use AVCaptureVideoDataOutput and AVCaptureMovieFileOutput at the same time?

I can't answer the specific question put, but I've been successfully recording video and grabbing frames at the same time using: AVCaptureSession and AVCaptureVideoDataOutput to route frames into my own code AVAssetWriter, AVAssetWriterInput and AVAssetWriterInputPixelBufferAdaptor to write frames out to an H.264 encoded movie file That's without investigating audio. I end up getting CMSampleBuffe
