title: 60/120fps preview data on an Android device?
body: <p>We would like to process 120 fps  (or 60fps) camera preview data using Neon assembly or GPU shaders to perform a simple image processing operation (eg 3x3 convolution).
  We are NOT interested in displaying the image on the screen so the camera data should go directly to a SurfaceTexture.</p>
  
  <p>We thought we could do this using Camera2 API on a Nexus 5 using CameraConstrainedHighSpeedCaptureSession  but have been unsuccessful. </p>
  
  <p>There is no currently functional code on the internet (at least the part we have scraped) that allows this and yet it seems probable that the functionality exists.</p>
  
  <p>The best example of using the Camera2 API for highspeed recording is here: <a href="https://github.com/PkmX/lcamera">https://github.com/PkmX/lcamera</a></p>
  
  <p>In order to try to encourage someone to post a solution I am putting a bounty on this question.</p>
