[FFmpeg-user] Extract motion vectors and visualize as actual picture data

Hey guys. I'd like to extract motion vectors out of a video file, but I
don't want those little arrows superimposed over the picture as is done by
the codecview=mv_type=fp video filter. I'd prefer to have the vectors
output directly as either the luminance channel or one or more of the RGB
channels. Is that possible with ffmpeg?
