Maybe expected/normal, but when launching two pipelines in parallel doesn't
work:
libva info: VA-API version 0.34.0
libva info: va_getDriverName() returns 1
libva error: va_getDriverName() failed with operation failed,driver_name=i965
ERROR: Pipeline doesn't want to pause.
ERROR: from element
/GstPipeline:pipeline0/GstVaapiEncodeH264:vaapiencodeh264-0: Could not
initialize supporting library.
Additional debug info:
gstvideoencoder.c(1426): gst_video_encoder_change_state ():

The latest libva has supported drm render node, the application should open /dev/dri/renderD128 instead of /dev/dri/card0.

I checked gst-vaapi 0.5.9 and 0.5.10.  gst-vaapi 0.5.9 fails however gst-vaapi 0.5.10 works fine. So there is nothing to do in the driver.
