Is it possible with ffmpeg psnr filter to get a psnr measurement with more than 2 digits?
for example
ffmpeg -i video1.yuv-i video2.yuv -lavfi psnr=stats_file=psnr_stats.txt -f null -
psnr_stats.txt looks like:
n:1 mse_avg:131.63 mse_y:198.03 mse_u:45.96 mse_v:84.51 psnr_avg:38.99 psnr_y:37.23 psnr_u:43.57 psnr_v:40.93
n:2 mse_avg:153.95 mse_y:236.57 mse_u:49.66 mse_v:93.00 psnr_avg:38.31 psnr_y:36.46 psnr_u:43.24 psnr_v:40.51
Is it possible to make it output more than 2 decimal digits?
PS: I need to work with > 8 bits videos, therefore tools that compute PSNR with 255 as max are not suitable
