Original commit message from CVS: * gst/deinterlace2/gstdeinterlace2.c: (gst_deinterlace_simple_method_interpolate_scanline), (gst_deinterlace_simple_method_copy_scanline), (gst_deinterlace_simple_method_deinterlace_frame): * gst/deinterlace2/tvtime/greedy.c: (deinterlace_frame_di_greedy): * gst/deinterlace2/tvtime/greedyh.c: (deinterlace_frame_di_greedyh): * gst/deinterlace2/tvtime/scalerbob.c: (deinterlace_scanline_scaler_bob): * gst/deinterlace2/tvtime/tomsmocomp.c: (Fieldcopy): * gst/deinterlace2/tvtime/weave.c: (deinterlace_scanline_weave), (copy_scanline): * gst/deinterlace2/tvtime/weavebff.c: (deinterlace_scanline_weave), (copy_scanline): * gst/deinterlace2/tvtime/weavetff.c: (deinterlace_scanline_weave), (copy_scanline): Use oil_memcpy() instead of memcpy() as it's faster for the sizes that are usually used here.
