>-sws_flags +accurate_rnd
sws_flags does not work at all, stop inserting it everywhere, it has no
affect. -vf scale=flags=accurate_rnd is not the real fix for this, even if
it works fine. The better fix is conversion to rgb24 first if you go from
bgr to yuv420p. The reason being accurate_rnd has effect on rgb to yuv420p
too.
Also bmp is very much affected, since it uses bgr24.
