[mythtv-users] VDPAU failing on an ION

[Brian J. Murrell]

Hi,

Using mythtv fixes/0.27 [v0.27.6-27-g3783dc8 on an ION which has
previously had no troubles with VDPAU, I'm getting the following
errors:

Nov 20 12:17:26 pvr-lr mythfrontend.real: mythfrontend[3468]: E CoreContext mythrender_vdpau.cpp:1581 (CreateDevice) VDPAU: Error at mythrender_vdpau.cpp:1581 (#1, Unknown)

The machine does have a working VDPAU:

The MythFE binary does seem to be finding the VDPAU library:

# lsof -n -p 3468 | grep vdpau
mythfront 3468 mythtv  mem    REG       0,30  1867288    34498 /usr/lib/nvidia-304/vdpau/libvdpau_nvidia.so.304.132 (server:/usr)
mythfront 3468 mythtv  mem    REG       0,30    13792     2431 /usr/lib/i386-linux-gnu/libvdpau.so.1.0.0 (server:/usr)

Anyone got any ideas what's stopping MythFE from using VDPAU given that
vdpauinfo doesn't seem to have a problem?

Cheers,
