How to Warp an YUV image in Vulkan

Vulkan
1

I need to write a Vulkan app which has a compute shader which takes:

  1. YUV image, each pixel has 3 bytes for Y,U,V components with values between 0…255
  2. warping grid for each pixel a vec2 coordinates floats with values 0.0 … 1.0
    and it returns the output buffer with the warped image.

I was told that I can use texture() for that but I couldnt figure out how to do it.

Any help much appreciated!
Thanks,
Andrei
