Use smaller dimension for resolution height

Previously the code assumed the height was always the second value in the "WxH" resolution string. This change splits the resolution into parts, verifies there are two components, and uses the smaller dimension (min) as the height to correctly classify vertical videos. Also avoids potential index errors when the resolution string is malformed.
