Comment 12 for bug 432172

libvdpau explicitly searches for /usr/lib/vdpau/libvdpau_${driver}.so.1. So, the files must exist there. There is a fallback in libvdpau to just search for libvdpau_${driver}.so (with no path) which will rely on ldconfig, but that's only to support older drivers that put the VDPAU driver directly in /usr/lib instead of in /usr/lib/vdpau. There shouldn't be any libvdpau_nvidia.so (i.e. without .1) in the new scheme. The files shouldn't be in the ldconfig search path, because applications don't directly link against them.
