Hi,

How to calculate psnr and ssim? I tried with encoding and getting psnr value but not sure how it is calculating it and with decoding it is not giving any value. With JM I use to calculate PSNR with input.yuv and out.yuv files. If someone can tell, let me know how it is calculating PSNR in ffmpeg. Thanks.
