You can use any sample, samples are irrelevant. just report resolution used.
Also compare with CPU solution with just v360 filter.

For yuv420p inputs:

ffmpeg -init_hw_device vulkan=vulkan -i INPUT -filter_hw_device vulkan
-vf hwupload,v360_vulkan=fisheye:e:ih_fov=180:iv_fov=180:w=2048:h=1024,hwdownload,format=yuv420p
-f null -

ffmpeg -i INPUT -vf v360=fisheye:e:ih_fov=180:iv_fov=180:w=2048:h=1024 -f null -

Just make sure that you get same output resolution in both cases. If
not, adjust w/h accordingly.
