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