vdpauinfo log with va_gl back-end on Intel GMA HD3000 none

Description carasin 2013-08-21 07:03:28 UTC 
Description of problem:

There is a VDPAU va_gl back-end that allows using VAAPI for the hardware accelerated video playback over the VDPAU. Now libvdpau tries to choose libvdpau_nvidia.so instead libvdpau_i965.so when using Intel HD Graphics. It happens because intel driver does not report its name correctly over DRI. There is a patch to fix this issue:

I've applied the patch and built the package. I've updated xorg-x11-drv-intel on my laptop with F19 installed. Now vdpauinfo says:
>>> $ vdpauinfo 
>>> display: :0   screen: 0
>>> Failed to open VDPAU backend libvdpau_i965.so: cannot open shared object file: No such file or directory
>>> Error creating VDPAU device: 1
And if I install libvdpau-va-gl then vdpauinfo says that HW-accelerated video playback exists! Now there is no need for VDPAU_DRIVER=i965 option!
