Comment (by ryandesign@…):

 So far, I have not figured out how to tell ImageMagick to use ffmpeg. The
 delegates.xml file is created at build time, and the placeholder
 "`@MPEGDecodeDelegate@`" is replaced with the mpeg decode delegate program
 name. I don't know how to tell ImageMagick's configure script what program
 name it should use there.
