That should be right. Check that libvidpau.so (it's in /usr/lib) points
to something meaningful. On this box tracing /usr/lib/gcc/x86 etc
points to /usr/lib and I have this:
[root at tor1 lib]# ls -al libvd*
lrwxrwxrwx 1 root root 34 2010-03-17 13:40 libvdpau_nvidia.so ->
lrwxrwxrwx 1 root root 13 2010-03-17 13:40 libvdpau.so -> libvdpau.so.1
lrwxrwxrwx 1 root root 21 2010-03-17 13:40 libvdpau.so.1 ->
-rwxr-xr-x 1 root root 3624 2010-03-17 13:40 libvdpau.so.195.36.08
lrwxrwxrwx 1 root root 33 2010-03-17 13:40 libvdpau_trace.so ->
In your case it should point to libvdpau.so.173.14.25.
Another thing to check, I have found, is the listing order in
Mine looks like this:
Your setup may be choking on /usr/lib/libvdpau.so because it needs to
find/see the 64bit files first. (Don't know: just guessing here! I build
trunk svn with vdpau on Fedora 12 x86_64 without seeing this so it's
got to be a setup problem of some sort.
One thing to try *before* nuking things, would be to edit xorg.conf to
use the vesa driver, reboot and then remove all the nvidia/vdpau stuff
using yum and then re-install. (I presume, from rpmfusion).
Please let me know if anything I say offends you.
I may wish to offend you again in the future.
