Yes, it basically amounts to that, but there are various questions.
For example if there's a filter that can't change parameters without
losing frames (due to internal buffering latency), should you
completely reset this filter and give bad output? Or should you insert
scale on one or both sides of it to hide the format/size changes from
it? I don't know what the best answer is...
