Hi All,

I have installed vdpau with the hopes of enabling the G-streamer VAAPI based
plugins on my graphics card. When I type in vainfo in the terminal I get:

vainfo

libva info: VA-API version 0.39.0
libva info: va_getDriverName() returns 0
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/nvidia_drv_video.so
libva info: Found init function __vaDriverInit_0_39
libva info: va_openDriver() returns 0
vainfo: VA-API version: 0.39 (libva 1.7.0)
vainfo: Driver version: Splitted-Desktop Systems VDPAU backend for VA-API -

      VAProfileMPEG4Simple            : VAEntrypointVLD
      VAProfileMPEG4AdvancedSimple    : VAEntrypointVLD
      VAProfileH264Baseline           : VAEntrypointVLD
      VAProfileH264Main               : VAEntrypointVLD
      VAProfileH264High               : VAEntrypointVLD
      VAProfileVC1Simple              : VAEntrypointVLD
      VAProfileVC1Main                : VAEntrypointVLD
      VAProfileVC1Advanced            : VAEntrypointVLD

I then installed gstreamer1.0-vaapi plugins however when I go to run a
pipeline with a vaapi plugin, for example:

gst-launch-1.0 v4l2src device=/dev/video0 do-timestamp=true !
video/x-raw,format=I420,width=1920,height=1080,framerate=60/1 ! vaapijpegenc
! rtpjpegpay ! multiudpsink clients=192.168.0.15

I get:

Setting pipeline to PAUSED ...

libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/nvidia_drv_video.so
libva info: Found init function __vaDriverInit_0_39
libva info: va_openDriver() returns 0

When I run this same pipeline with jpegenc the software encoder instead of
vaapijpegenc it runs fine. How can I fix this? I would like to be able to
use the G-Streamer VAAPI plugins.
