Hi Eli,
if there is an interpolation method that interpolates by nearest
neighbor, than this should even be faster than SWS_FAST_BILINEAR.
All other should take more time than SWS_FAST_BILINEAR.
Best regards

Currently it seems SWS_FAST_BILINEAR is the fastest for this specific use
case.

Hi Eli,
SWS_AREA should be the fastest, if it is considered to be the nearest
neighbor operation.

Hi,
I need to scale down a h.264 from 720/480 to 360/320 (half). Quality is
not
that important as this is for simple preview.
I'm trying to squeeze max performance on an android device.
Can anyone suggest the best flag to use (e.g. SWS_AREA, SWS_BICUBIC etc.)
Thanks
Eli
