Having an AVStream object how should I reliably distinguish whether this is video or image stream?

I've tried to use duration. If it's 0 - we are having image (system constraints allows for such assumption). But it turns out that duration have special meaning for images - the number of images stored in file.

Is there any tricks to detect image stream more reliably?
