Next: -35- I want to capture a still image from video using a shell script. The Capture tool doesn't seem to be appropriate because it waits for the user to click the mouse button. How can I accomplish this?
Previous: -33- I want to write a program which can create a JPEG- compressed movie file compatible with the Cosmo Compress board, SGI's hardware JPEG accelerator. How do I do this?
Subject: -34- I simply want to create a JPEG-compressed movie which is
compatible with the Cosmo Compress board. I don't want
to write my own program. How do I do this?

In IRIX 5.3, there are three ways to do this:
1) Use the dmrecord utility to record live video from the Galileo
or Indy Video options.
2) Use the Capture tool to record live video from the Galileo
or Indy Video options.
3) Use the makemovie utility to generate a cosmo-compatible movie
from a collection of still images. Here is an excerpt from the
manual page:
To make an odd interlaced, 640x480, JPEG compressed movie with
top-to- bottom orientation (of the sort that can be played back on
the Cosmo compression board) from image files img1.rgb, img2.rgb,
and img3.rgb:
makemovie -o movie3.mv -c jpeg -s 640,480 -i odd -t \
img1.rgb img2.rgb img3.rgb
In IRIX 6.2, you should use the dmconvert utility to accomplish this
task. (makemovie has been retained as a compatibility layer atop
dmconvert). See the manual page for dmconvert.
