You cannot use AVCodecTag to achieve this, library users are not
supposed to access it.

FFmpeg does not export information about supported codecs in containers, this
information is not even always available within libavformat, users are allowed
to abuse the library.

I believe you - as gui author - are responsible to offer compatible
combinations to
your users.
