Video Image Processing with dynamic image size

Hello amos

You could do the resampling by discarding one chroma sample for each pixel. It should look like this:

-- Input:

-- Y1Cb1Cr1, Y2Cb2Cr2, Y3Cb3Cr3, Y4Cb4Cr4

-- Output:

-- Y1Cb1, Y2Cr2, Y3Cb3, Y4Cr4

You just need to figure some way to synchronize the Cb or Cr order (you should use the sync signals for this) to ensure the resulting image is correct.

Hope this helps

Best regards,
