PPMTOYUVSPLIT

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.
