    Nvidia VDPAU & VLC

    So I have not been in my 14.10 install for a wile .........I came hear to see what ver. of VLC I had hear because I was trying to get VDPAU hardware exelarated video decoding working in 14.04 (VLC ver to low in 14.04) .

    I opened VLC (hear in 14.10) and in tools>preferences>input/codecs the VDPAU video decoder is their in the hardware-accelerated decoding dropdown and it dose work ,,,,,the Nvidia xserver settings window>video engine utilization % shows it's being used wile playing a H264 MPEG-4 in VLC

    NOW hers the Quirk wile the video is playing it appears as the background in all terminal windows (Konsole or yakuake) the background of all application windows and the background of the desktop cube effect .

    BUT it will not be captured in a screenshot ,,,,,,even though the video is playing in the background of dolphin for instance when you take the screenshot and then save and open in Gwenview the saved pick is just dolphin as it would look normaly ,,,,,,,,,,,strange

    after playing with this I ran off updates (dist-upgrade) 124 of them including Nvidia ,,,,this is the nvidia driver from the repo,,,,,,,,,,,,but still the same.

        just adding that the ver.of VLC in 14.04 dose not seem to have VDPAU support like in 14.10 .

        But Qmplay2 from http://ppa.launchpad.net/samrog131/ppa/ubuntu dose use it in 14.04 ........with the FFMPEG VDPAU

          yes , yes I know ,,,,,this is posted in 14.10 ,,,,,but sence it's hear .

          the older VLC (older than in 14.10) in 14.04 only has an option in preferences>input/codecs>hardware-accelerated decoding for "video acceleration (VA) API" and not VDPAU like in 14.10's ver. of VLC

          installing the

          Code:
          Start-Date: 2015-01-25  12:56:22
Commandline: apt-get install vainfo
Install: vainfo:amd64 (1.3.0-2), libva-wayland1:amd64 (1.3.0-2, automatic), libva-drm1:amd64 (1.3.0-2, automatic)
End-Date: 2015-01-25  12:56:25

Start-Date: 2015-01-25  13:05:40
Commandline: apt install vdpau-va-driver
Install: vdpau-va-driver:amd64 (0.7.3-2ubuntu1.2)
End-Date: 2015-01-25  13:05:41
          in 14.04 then lets VLC use the hardware-accelerated decoding with the Nvidia-GPU

          Code:
