VDPAU troubles, "Trying to open /usr/lib64/dri/nvidia_drv_video.so" [14.1,current]

I'm marking the thread solved for now.
It turned out that the package "libvdpau-va-gl-0.3.4-x86_64-1ponce" created some scrips in /etc/profile.d/ that set the VDPAU_DRIVER environment variable to va_gl and these files did not get removed on package uninstallation.
I am now merely running libvdpau-1.1 and the proprietary NVIDIA driver.

vdpauinfo now shows progress.

Original post:
I am not very experienced with VDPAU so I can't give much info from myself, if there is something I should post, please tell me.

The error I am getting:
[VS] Software VDPAU backend library initialized
libva info: VA-API version 0.37.0
libva info: va_getDriverName() returns 0
libva info: Trying to open /usr/lib64/dri/nvidia_drv_video.so
libva info: va_openDriver() returns -1

vdpauinfo dump:
http://pastebin.com/qt96c8H0

The VDPAU tab in the nvidia-settings tool reports API version 1, with no supported codecs listed.

I'm on Slackware 14.1 current, 64 bit, multilib.
I'm using an Nvidia GTX 750Ti card.
I'm using the proprietary nvidia driver version 352.30, straight from the *.run package, not the slackbuild one.
I have the following libraries installed:
libva-1.5.1-x86_64-1
libva-compat32-1.5.1-x86_64-1compat32
libva-intel-driver-1.5.1-x86_64-1
libva-intel-driver-compat32-1.5.1-x86_64-1compat32

libvdpau-1.1-x86_64-1
libvdpau-va-gl-0.3.4-x86_64-1ponce
vdpauinfo-0.9-x86_64-1ponce

The ponce packages have been built via sbopkg and the current sBO repo.

I have not been able to build the vdpau-video package.
http://pastebin.com/ypmWmWF7
is the build failure dump.

I have tried removing the packages and reinstalling the driver, it offered to install (some deprecated?) wrappers that come with the driver package for me.
That didn't solve the problem. I was prompted to supply the libvdpau-va-gl library in that case.

Is this something that can be fixed? Or did I perhaps buy a card that doesn't support VDPAU under Linux? (Edit: Internet searches suggest it has support for it, some reviewers actually calling it excellent.https://www.phoronix.com/scan.php?pa...50linux&num=13 )

Maybe, as a quick try, grab Alien Bob's vlc package as that has vdpau built in and see if it works.

I can't access pastebin at work, so I am unable to help you with your compile error, but hopefully someone else can chime in.

Hm, playback withAlien Bobs VLC seems accellerated. The file I tried playing back with mplayer, which had the video lag behind the audio is playing correctly. Thank you for pointing me into that direction.

The rest of the log is mostly about warnings and notes about various macros.

I have tried building the 14.1 version of the package but it doesn't compile either. Don't have the log for that on hand right now though. I can add it, if it might be helpful.
