            Bug ID: 93573
           Summary: bad performance with 4k h264 video
           Product: xorg
           Version: git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
          Assignee: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
          Reporter: freedesktop-lIBOoy2+GI7scQ4cX5LuPg@public.gmane.org
        QA Contact: xorg-team-go0+a7rfsptAfugRpC6u6w@public.gmane.org

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)

screenshot of the video

also I noticed that the output is total garbage. so I assume something else is
fishy here.

crash while playing reencoded video

I just reencoded this video just to test if special encoding flags would let
nouveau play that video, but I got a crash instead

side note: slightly smaller videos (3840x2100) are working much better, so
maybe there is only a tiny issue somewhere
