If you think there is something that is needed by this profile and cannot be
set through the existing options, you have to be more specific.
Copy and pasting some text from some encoder implementation is not usefull,
you will have to obtain a recent copy of the mpeg4 spec and read it.

With that you can then either implement it and send a patch together with a
quote from the spec proofing that the patch is correct or open a feature
request, again with a quote from the spec listing the limitations needed
by this profile.
