I'm going to guess that your comment is Cehoyosese for "your command is
wrong".

No. (On the contrary, my comment meant that I - still - don't know what
your original command line is meant to do or show.)
I believe `-f null` is a very useful debug feature, including for both
crashes and performance tests.
Imo, it - generally - can not be used to show that encoding doesn't work
though: It never produces any output which in this specific case is
exactly the relevant difference: If I use the same options you used for
`fdkaac` (which defaults to `-f ipod`) with `ffmpeg`, I get no error. The
error you see with `-f null` can also be reproduced with `-f adts` which
allows to be translated into an `fdkaac` command line which again shows
the identical error - imo indicating the only thing we can fix is being
more verbose.
An additional issue is of course that since your command line made the
implicit assumption that it ''always fails'' for the given profile (esp.
because of the comparison with the fdk cli), it took me considerable more
time to understand the issue.
