The problem is that Totem is using the videobalance element, which is a
pure software element. Using software element prevent using hardware
acceleration like libva or VDPAU.

I suggested a while ago to add color balance interface to clutter-gst,
and change totem code to use that instead, which end up with the
conclusion that clutter should provide effects to implement this
feature. I haven't look at the status of it since.
