Success! Was: Testing the new i915 driver (HD Graphics 4400)

I am glad I was able to be of assistance :)

Does Vimb use multimedia/gstreamer1 or multimedia/gstreamer as codec backend?

If it uses multimedia/gstreamer, then there's nothing you can do, since multimedia/gstreamer does NOT have VAAPI plugin. multimedia/gstreamer has only VDPAU plugin (for nVidia GPUs), but not VAAPI.

On the otherhand, multimedia/gstreamer1 has multimedia/gstreamer1-vaapi plugin, which should enable hardware decoding. 

So, if Vimb uses multimedia/gstreamer1, then just install multimedia/gstreamer1-vaapi package and you should get proper hardware decoding. If this does not help, then the fault is in GStreamer1 filter priorities.
