--- Comment #6 from KJ Liew <liewkj-/E1597aS9LQAvxtiuMwx3w@public.gmane.org> ---
I don't know how you had verified VDPAU to make sure it is working. Running
vdpauinfo is not enough. I used the VA-API translation layer for VDPAU backend
since my goal is to get VA-API. I had also verified that the VA-API translation
layer worked with nvidia-390xx propriety blobs and Chromium-vaapi accelerated
H264 playback.

The change *ONLY* fixed "vainfo & vdpauinfo SIGSEGV due to NULL pointer".

There was a long pause, I think the GPU process crashed and then restarted with
more lengthy logs spit until Chromium was killed
