[x264-devel] about motion compensation

[张睿]

in x264, the 3 half-pel planes are interpolated after encoding each frame,
which is implemented in x264_frame_filter().
but I don't understand why more 8 pixels are interpolated than origin image
width, and I wan't to know if the 3 half-pel planes could be just
inpterpolated without dealing with the 8 pixels.
thanks!
