autoplug_select ?? or autoplug_factories 

and only sort this small list by our metrics (number of common
> caps features, etc). Gives us the lookup advantage plus a small extra cost for
> sorting a list with less than 10 elements (which is basically for free)
> 3) We would use lookup there and then take the first iterator to the used
> decoder factory, and continue iterating from there on until the decoder factory
> changes. Gives us the lookup advantage and no extra costs
