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 col-
       ors into one. The YUV values  are  scaled  according  to  CCIR.601,  as
       assumed by MPEG.
