The tool is generating APSNR for the YUV components for the two input YUV’s. We would like to know the formula used to calculate YUV APSNR in YV12 format. We have individual PSNR’s for Y, U & V separately in the excel file generated (APSNR_curY, APSNR_curU, and APSNR_curV) and also overall YUV PSNR (APSNR_curYUV). We would like to know, what is the formula used to calculate APSNR_curYUV for every frame
