--- Comment #1 from Scott D Phillips <scott.d.phillips at intel.com> ---
This behavior starts with the commit:

75a20de vaapidecode: Use video format derived from decoded surface as
default...

That commit exposes some deficiencies in gstreamer-vaapi and vaapi/intel-driver
regarding GRAY8 (Y800) videos. When you vaDeriveImage() with a surface from the
failing video you get back an image with fourcc==Y800 (even though that format
isn't returned by vaQueryImageFormats()).

The only change I see needed to gstreamer-vaapi to work with this video is
adding GRAY8 to all the caps. Some changes in vaapi/intel-driver will be
required though, see:
