vainfo shows the supported entry points base on VAAPI. It doesn't mean
vulkan also support them. You may use ffmpeg-vaapi to decode if you
want:
https://trac.ffmpeg.org/wiki/Hardware/VAAPI
And more supported codec/formats can be found in intel media-driver's
wiki:
https://github.com/intel/media-driver
Thanks

Is there a way to list the video formats supported by Vulkan?
