I am writing a metal based camera for recording video which will allow users to pit image overlays on the video. It will also allow them to apply filters to the video (sepia, B&W etc).
I am able to display all of this on an MTKView, but now how do I convert this rendered texture back to video frames so I can write the video to disk?
