Quick slideshow, part II

Quick slideshow, but not too quick. I decided just to guess at the number of frames to hold each photo. Five, about 5 photos/sec, was too quick. Half that fast is okay for us. We have lots of duplicates. Laziness gave me this:

#!/bin/bash
for item in `ls ${1}/dsc[0-9]*.jpg`
do
  convert $item /tmp/`basename ${item} .jpg`.ppm
done

rm /tmp/list.photos
touch /tmp/list.photos
for j in `ls /tmp/*.ppm`
do
        for i in 1 2 3 4 5 6 7 8 9 10
        do
                echo $j >> /tmp/list.photos
        done
done

cat /tmp/list.photos | xargs -n1 cat | ppmtoy4m | mpeg2enc -o $2.m1v

I wonder if it's worth rewriting for configurability. Takes longer to run the script than to write it. The first MPEG compilation is diane.m1v (16 MB).
