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
1993 by Andre Beck. (Andre_Beck[:at:]IRS.Inf[:dot:]TU-Dresden.de)
