Ok; I was looking at the wrong place ;-) (I started by looking at the impact
of this change on ff_isom_write_avcc()).

I now see how your idea can simplify the code. Unfortunately, I got
sidetracked by some other issues, and I've not been able to test these
changes. I attach a patch, to show how the final result will look like,
but be aware that the patch is only compile-tested.
I am not sure I like the way I changed ff_isom_write_avcc()... I'll have
to think about it a little bit more.

I'll probably have a tested patch next week.


				Thanks,
