applied the case for DNxHD, for the more general case, please
explain which case(s) and software need them, and how to reproduce
that
I dont see where the text would allow one to add such padding by
ones own choice. I just see a note that says that parsers need to
cope with it. Thats not the same as saying its ok to add it in all
cases.
But maybe iam missing something, i didnt read the whole document
