The ///< or /**< form of doxygen comments are only to be used when the documentation follows the member and the comment block starts on the same line as the member. This commit fixes wrong uses of them; in particular, this fixes the comment for mb_height in H.264 SPS's structure which was wrongly added to mb_width.
