The "FRAME_INTERPOLATION" definition IS USED BY THE CURRENT ipp SAMPLE
CODE (H264 encoder) to switch the way how the half pel got interpolated.
But I am not clear about the difference if I turn it on or off. My unstanding
(1) When the FRAME_INTERPOLATION turns on, all the half pel on
the frame will be interpolated once and saved for motion estimation
(2) otherwise, the half pel interpolation is happen on-the-fly per block basis during the sub-pel ME.
Am I right? Thanks and Regards.
