The :ref:`h264` currently expands to "ITU H.264", which means in the documentation, in the case above, it ends up as The bitstream parameters are defined according to ITU H.264. Unless there=E2=80=99s a specific comment, refer to the specification for the documentation of these fields, section 7.4.2.1.1 =E2=80=9CSequence Paramet= er Set Data Semantics=E2=80=9D. I could change the reference to have "ITU-T Rec. H.264 Specification (04/2017 Edition)". Would that work for you?
