[PlanetCCRMA] scrolling screen credits

[Tom Poe]

Is anyone creating scrolling screen credits for videos?  Is there a neat 
way to do this?  I tried creating a .png image, using mencoder to create 
a small .avi, then running ffmpeg with vhook, but can't get it to go.  
Here's the error message:
$ ffmpeg -sameq -i input.avi -vhook 'imlib2.so -x 0 -y -1.0*N -i 
credits.png' output.avi FFmpeg version SVN-r6005, Copyright (c)

I don't know what "Failed to Configure imlib2.so means.  Any help or 
pointers to something that works.
Thanks, Tom
