Remove the pdiff_lut_scale in nlmeans and increase weight_lut table size from 2^9 to 500000, this change will avoid using pdiff_lut_scale in nlmeans_slice() for weight_lut table search, improving the performance by about 12%. (in 1080P size picture case). Use the profiling command like: perf stat -a -d -r 5 ./ffmpeg -i input -an -vf nlmeans=s=30 -vframes 10 \ -f null /dev/null without this change: when s=1.0(default value) 63s s=30.0 72s after this change: s=1.0(default value) 56s s=30.0 63s Reviewed-by: Carl Eugen Hoyos <ceffmpeg@gmail.com> Signed-off-by: Jun Zhao <mypopydev@gmail.com> Signed-off-by: Clément Bœsch <u@pkh.me>
