[FFmpeg-devel] Exposing CrystalHD's hardware scaling?

One of the CrystalHD's features is that it can scale frames before
back over to system memory. While any modern system can accelerate
using Xv or similar, letting the CrystalHD do it means that you don't
to copy as many bytes, and sometimes this will make the difference
playable and unplayable.
So, my question is what's a way to expose this concept? You need to
modify decoder state (setting the scaling flag and the desired size)
decoder option seems clunky - you'd much rather set the size the usual
and then have it 'accelerated'. Is that practical? Could it be done
