A good container format can use any codecs. Bad ones are limited to
small sets of compatible codecs, for practical purposes anyway.
(FFmpeg can normally put any codec in any container, but the results
most likely won't be playable on most players.)

FFmpeg does not provide any tables to identify which codecs a
container supports. :(
