NAME

       ppmtoyuvsplit - convert a portable pixmap into 3 subsampled raw YUV files

SYNOPSIS

       ppmtoyuvsplit basename [ppmfile]

DESCRIPTION

       Reads  a portable pixmap as input.  Produces 3 raw files basename.Y, basename.U and basename.V as output.
       These files are the subsampled raw YUV representation of the input pixmap, as required  by  the  Stanford
       MPEG  codec.  The  subsampling is done by arithmetic mean of 4 pixels colors into one. The YUV values are
       scaled according to CCIR.601, as assumed by MPEG.
