From: Mark Reid <mindmark@gmail.com> if the float pixel * 65535.0f > 2147483647.0f lrintf may overfow and return negative values, depending on implementation. nan and +/-inf values may also be implementation defined clamp the values between 0,1 before scaling, so lrintf always works. values <=0.0f, -inf, nan = 0.0f values >=1.0f, +inf = 1.0f --- libswscale/input.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
