          Priority: medium
            Bug ID: 66450
          Assignee: dri-devel at lists.freedesktop.org
           Summary: JUNIPER UVD accelerated  playback of MPEG 1/2 streams
                    does not work
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: eugene.shalygin at gmail.com
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: unspecified
         Component: DRM/Radeon
           Product: DRI

When playing MPEG 1 or 2 streams using mplayer (or mplayer2 or ffplay or mpv)
there is no output, only black rectangle. 

$vdpauinfo declares MPEG support:

MPEG1                16  9216  2048  1152
MPEG2_SIMPLE         16  9216  2048  1152
MPEG2_MAIN           16  9216  2048  1152


Output from ffmpeg shows:
Unsupported PixelFormat xvmcidct (16)
Unsupported PixelFormat xvmcmc (15)

acceleration of h264 works fine, so I conclude that UVD is initialized
succesfully

Radeon Mobility HD 5850

Kernel 3.10.0, libdrm and mesa are from git master (30.06.2013)
