You modified the tags for BitRate and ProfileAndLevel, but didn´t adapt the
mxf_write_mpegvideo_desc function. The other UIDs you added aren´t used
elsewhere.
They could be used within the mxf_write_mpegvideo_desc function function,
as Maksym did in his patch.

This seems unrelated. In any case AVC Baseline support should not be
dropped.

This looks wrong to me. Is it intended to write continuity count twice?
But I´m not an mxf expert.
Someone with more experience should have a look at this patch.
