installing VDPAU on Fedora 20 ??

[sean darcy]

On F20:

mesa-vdpau-drivers-10.1.5-1.20140607.fc20.x86_64
libvdpau-0.7-1.fc20.x86_64
vdpauinfo-0.1-1.fc20.x86_64

/usr/lib64/vdpau/libvdpau_radeonsi.so.1
/usr/lib64/vdpau/libvdpau_radeonsi.so.1.0.0

Xorg.0.log:  RADEON(0): Chipset: "KAVERI" (ChipID = 0x1318)

dmesg:
[drm] UVD initialized successfully.
...
[drm] VCE initialized successfully.

But

export VDPAU_DRIVER=radeonsi; vdpauinfo
display: :0.0   screen: 0
Error creating VDPAU device: 23

and X log has no reference to vdpau:

# grep -i vdpau /var/log/Xorg.0.log
#

What am I missing?
