Have you tried the 'video' package from Octave-Forge? I've never used
it, but I'm under the impression that it works with fairly recent
versions of ffmpeg.

Whenever I need to make animations, I use 'print' to generate a file for
each frame in the animation. Then I call ffmpeg from the shell to
generate a video from these files. Not an elegant solution, but it
works...
