           Summary: r600g: gl output in mplayer have no colors if used
                    with a fragment program with additional lookup and
                    bicubic B-spline filtering
           Product: Mesa
           Version: git
          Platform: All
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r600
        AssignedTo: dri-devel at lists.freedesktop.org
        ReportedBy: virtuousfox at gmail.com


when i try to play video in mplayer with option 'gl:yuv=4,lscale=1,cscale=1'
and r600g in use, it displays no colors. if it's 'gl:yuv=3', colors are ok.
'gl:yuv=5' seems also ok.
sorry, i  haven't tested yuv=4 without 'lscale=1,cscale=1' and immediately
rebuilded mesa without gallium, so i don't know which of those to blame
actually. my bet is 'yuv=4' and "a fragment program with additional lookup".

by the way, what yuv and *scale options do you recommend for use with ATI/AMD
>=r600 cards in terms of performance and quality ?
