What is the purpose of these parameters? How do they interact with the maxHeight and maxWidth parameters?

    Aspect ratioX and aspect ratioY have nothing to do with maxHeight/Width. This field is related to pixel aspect ratio and communicates the display charecteristics. For details please refer to notes after 4.2.2.2 IH264VENC_DynamicParams table of the H.264 encoder user guide. By default, 1:1 ratio is choosen for H.264 encoder. It follows the definition as described in section E.1.3 of H.264 standard.
