[Bug 15065] New: xv overlay when rotated is fail

           Summary: xv overlay when rotated is fail
           Product: xorg
           Version: unspecified
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
        ReportedBy: sb476-KWPb1pKIrIJaa/9Udqfwiw@public.gmane.org
         QAContact: xorg-team-go0+a7rfsptAfugRpC6u6w@public.gmane.org


The overlay does not work when the output is rotated (under randr12)

To reproduce:
1) Start nouveau, using randr12
2) xrandr -o 2
3) mplayer foo.avi
4) cry

Since rotation is commonly used for projectors (where there's a reasonable
chance of Xv being used), this is not a made up problem :)

Someone fixing the coordinate-fu would be awesome, but falling back to the
blitter is probably far far easier.

Very superficial investigation confirms the bug and suggests the overlay cannot
do rotation.

Blitter fallback would appear as the only solution.

If you have time to test with the binary blob and see how it deals with
rotation and overlay, the data would be greatly appreciated (mmiotrace).

From the nvidia README:

"        Option "RandRRotation" "boolean"
                Enable rotation support for the XRandR extension.  This
                allows use of the XRandR X server extension for
                configuring the screen orientation through rotation.
                This feature is supported on GeForce2 or better hardware
                using depth 24.  This requires an XOrg 6.8.1 or newer
                X server.  This feature does not work with hardware overlays,
                emulated overlays will be used instead at a substantial
                performance penalty.  See APPENDIX W for details.
                Default: off."

Testing with the nvidia driver confirms that even for the non-rotated case the
overlay is not used (when the above option is set), so it would seem falling
back to blitter is the answer.

Fixed in commit c8cec9b2 "randr12, xv: no overlay when the crtc is transformed"
