--- Comment #2 from Víctor Manuel Jáquez Leal <vjaquez at igalia.com> ---
That's odd. It works for me (intel vaapi driver with skylake):

gst-launch-1.0 -v videotestsrc !  vaapih264enc  ! video/x-h264 ! fakesink
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
Got context from element 'vaapiencodeh264-0': gst.vaapi.Display=context,

if I recall correctly, by default it is chosen the high profile. Does your
driver support high profile?
