Wow, you're opening a can of worms in a world of incompatibility. Have
you seen this (perhaps outdated, perhaps slightly incorrect) table,
just for iOS?
(Other sources for this information can also be found.)

And then check for websites which recommend how to encode for the web
for compatibility with iOS AND other mobile devices AND desktop, and tell you how
many variants of your video you need to provide, for "sufficient"
coverage. (Perhaps those days are over since a few years? Dunno.)

With iOS obsoleting itself every few years, few << 5. ;) (May be
exaggerated, I don't have enough data.)

I think you're deep into "wrapper" land, which needs to maintain
knowledge (and requirements like yours) outside of an encoder.

Just my $0.02,
