Gstreamer VAAPI plugins don't run on Nvidia GTX 1080

Hi Nicolas,
Thanks a lot for checking into that. It seems JPEG encoding and decoding is
not realistic to do on the GTX 1080. Do you know if it is possible to run
the VAAPI plugins on the Intel hardware (i7-8700k) while a GTX 1080 is
being used to drive displays?
Thanks
