Perhaps everyone here needs to read the docs better.

While looking at the code to try to understand just what this thing is
(it isn't metadata and should not be in AVMetadata), I came across the
private option for mov-like files named "-brand" which is described as
"Override major brand".

You should try -brand 3gp4 or 3gp6 or whichever you needed.
