[FFmpeg-devel] [PATCH] Add RSHIFT_POS and ROUNDED_DIV_POS

[Ramiro Polla]

Hi,

Currently there is RSHIFT(a,b) and ROUNDED_DIV(a,b), which work for
both negative and positive values of a. This patch adds variants that
only work on positive values of a, so it may be used on variables
known to be positive.

And another patch uses it in swscale.
