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.
