    VDPAU not working in 12.04?

    I just upgraded from 11.10 because VDPAU wasn't working there hoping that things were fixed in the next release. The system seems to work ok in general, but I get a lot of jumpy, stuttering video with quite a bit of tearing. When I select any VDPAU option in MythTV video playback setup screen, I get the "Failed to Initialize Video Playback" error message if I attempt to watch a recording.

    I tried installing from the edgers ppa as described in this thread, but I'm still getting the same error. Here's some output that seems to say that there's no nvidia driver found (same output before and after installing the edgers ppa code):
    Code:
    $ vainfo
    libva: VA-API version 0.32.0
    libva: va_getDriverName() returns 0
    libva: Trying to open /usr/lib/i386-linux-gnu/dri/nouveau_drv_video.so
    libva: va_openDriver() returns -1
    vaInitialize failed with error code -1 (unknown libva error),exit

    vainfo has nothing to do with vdpau. What video card do you have?

    Thanks. It's nvidia built into the motherboard. This is what lspci gives:
    VGA compatible controller: NVIDIA Corporation C68 [GeForce 7050 PV / nForce 630a] (rev a2)

    I must have misunderstood the thread that mentioned using vainfo to determine if the nvidia driver was in use and VDPAU was working. Regardless, VDPAU doesn't seem to work. This is from the front end log:
    Code:

    I have 3 machines running Myth FE on 12.04 and VDPAU works fine. Make sure that you have the Nvidia hardware drivers enabled.

    Your adapter doesn't support vdpau. Support began in the 8xxx series.
    If you ask for help, please have the courtesy to check for responses and thank the people who helped you.

    I can't believe the card isn't supported! I've been using it for years and on at least a couple of installs I think VDPAU setting worked, though apparently it wasn't getting any benefit of the VDPAU acceleration. Oh well...Thanks.
