Macroblock height of video sequence
Returns the macroblock height of encoded video sequence from sequence header.
Generally the macroblock height will be height/16, but if height is not a multiple of 16, macroblock height will be the minimum valid macroblock height that can accomodate the height. The value of pixels that are outside of height but within the encoded macroblock height is not defined.
