We recently added the libvdpau driver for GPU aided HW acceleration. It builds fine and other applications link to it appropriately. However, when running something like MPlayer that uses it, I get a message:
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 My searches seemed to indicate that the libvdpau_nvidia.so library is loaded with the nvidia proprietary drivers. I also found the comment: Nvidia devs recommend packagers to separate libvdpau from the proprietary nvidia kernel and driver installers as vdpau will we removed "real soon now" but that comment is about a year old. http://www.linuxquestions.org/questions/slackware-14/fresh-installation-of-slackware-14-rc2-libvdpau_nvidia-so-not-built-4175423181/ I also found: http://lists.freedesktop.org/archives/xorg-announce/2009-September/001036.html where it says: To actually use a VDPAU device, you need a vendor-specific implementation library. Currently, this is always libvdpau_nvidia. You can override the driver name by setting the VDPAU_DRIVER environment variable. My video is "NVIDIA Corporation NV37GL [Quadro PCI-E Series]", but it does noot seem that libvdpau is doing anything for me. Should this be removed from the book? Or, perhaps a note saying it is only useful in conjunction with the proprietary nvidia drivers? -- Bruce -- http://linuxfromscratch.org/mailman/listinfo/blfs-dev FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
