In general topology is need for every AVStream minidriver. For Stream Class
based topology was not usually used (I don't know what happened to it with
Stream Class 2.0)
In practise however only a very few applications require topology.
Something that builds complex graph or builds generic graph (MS VidControl,
for example) relies on topology to make intelligent decisions about graph
building logic.
Simple apps usually don't care about topology at all.
