I have a bunch of 30 second AVI files generated by my Canon S30 camera:

mvi_1329.avi: RIFF (little-endian) data, AVI, 320 x 240, ~15 fps,
video: Motion JPEG, audio: uncompressed PCM (mono, 11024 Hz)

Many of these files were taken with the camera rotated 90 degrees, and
it can be a bit jarring to watch them sideways on the screen.  Can
anybody suggest a program that can rotate these movies 90 degrees into
the correct orientation?

http://sourceforge.net/projects/mplayer/

mplayer -vf rotate filename.avi

I always thought mplayer was just a playing program, but a look at the
docs revealed that there is a companion program, mencoder, which does
exactly what I need.  Thanks for the pointer.

So my tentative solution is:

mencoder -oac copy mvi_3202.avi -ovc lavc -lavcopts vcodec=mpeg4 -vf
rotate -o test2.mpg

(The files are half as big after this process as well, perhaps another
benefit?)
