I noticed a while back already, that nouveau handles 4k video not that well
currently.

I tried it out with the cactus-4k video from here:
http://www.elementaltechnologies.com/resources/4k-test-sequences

Nvidia doesn't have any problem playing that video at full speed, but on my
kepler nve6 card even full reclocked nouveau only handles this at 45% speed and
the PVLD engine is at max load (only around 80% with nvidia)
