           Summary: Fix from bug 4686 for Xv corruption needed in Nouveau
           Product: xorg
           Version: git
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau at lists.freedesktop.org
        ReportedBy: sb476 at cam.ac.uk
         QAContact: xorg-team at lists.x.org


Current git version of Nouveau DDX has video corruption when the video is
larger than the screen res. This can be triggered by playing Elephants Dream in
HD in mplayer, or taking some smaller movie and using -vf scale=something:big.

The issue has only been observed when using YV12 output and the overlay (as is
the default) - use of the blitter port, or using -vf yuy2 does not display the
problem. Applying the two line fix from bug 4686 used in nv to Nouveau results
in correct playback.

Hardware is a NV31M [GeForce FX Go5600] (10d3:031a) in a laptop.
