I want to try this VAAPI backend for VDPAU. I have compiled mplayer with vdpau in Gentoo Linux (amd64) but I get this error:Failed to open VDPAU backend libvdpau_nvidia.so: cannot open shared object file: No such file or directory[vdpau] Error when calling vdp_device_create_x11: 1 The same error appears when I run vdpauinfo. The library seems to be linked:$ ldd /usr/bin/mplayer | grep vdpau    libvdpau.so.1 => /usr/lib64/libvdpau.so.1 (0x00007f8242fda000) And libraries exist:$ ls -l /usr/lib64/libvdpau.so*lrwxrwxrwx 1 root root    17 jul  8 22:24 /usr/lib64/libvdpau.so -> libvdpau.so.1.0.0lrwxrwxrwx 1 root root    17 jul  8 22:24 /usr/lib64/libvdpau.so.1 -> libvdpau.so.1.0.0-rwxr-xr-x 1 root root 14560 jul  8 22:24 /usr/lib64/libvdpau.so.1.0.0 $ ls -l /usr/lib64/vdpau/total 156lrwxrwxrwx 1 root root     23 jul  8 22:24 libvdpau_trace.so -> libvdpau_trace.so.1.0.0lrwxrwxrwx 1 root root     23 jul  8 22:24 libvdpau_trace.so.1 -> libvdpau_trace.so.1.0.0-rwxr-xr-x 1 root root  51032 jul  8 22:24 libvdpau_trace.so.1.0.0lrwxrwxrwx 1 root root     19 jul 12 21:34 libvdpau_va_gl.so -> libvdpau_va_gl.so.1-rwxr-xr-x 1 root root 105360 jul 12 21:34 libvdpau_va_gl.so.1
