Thanks for the suggestion. I'm still using DirectFB 1.0 where I seem to have something called dfblayer; is it the same thing? I guess not; I can't make it do anything. Anyway I have thrown together some code using the v4l2 API directly and it seems to work. The more complex bit was working out how to decode the mjpeg stream, as this format doesn't actually seem to be documented anywhere...
