This might be a problem with the Nvidia 304.132 driver, according https://devtalk.nvidia.com/default/topic/974456/f24-permission-problems-/?offset=2 . Apparently Direct Rendering and VDPAU playback only works for the root user when using that driver version.

The problem is also being reported at http://unix.stackexchange.com/q/321185/49753 and many other places. Apparently the only solution at the moment is to downgrade to the previous driver version (304.131).
