 Summary of the bug: using nlmeans_vulkan replaces the first frame with a
 green frame and also does not seem to do any nlmeans stuff at all. Playing
 around with the variables does not change the output in any way. (Tested
 with other files.)
 How to reproduce:
 First I created a testsrc file
 {{{
 ffmpeg -f lavfi -i testsrc=duration=10:size=1280x720:rate=30 -c:v
 av1_nvenc -preset p7 -pix_fmt p010le -cq 20 testsrc.mp4
 }}}

 Then I took the minimum command to get nlmeans_vulkan to work.
 {{{
 ffmpeg -init_hw_device vulkan=vk:0 -filter_hw_device vk -i testsrc.mp4 -vf
 "hwupload,nlmeans_vulkan,hwdownload,format=yuv420p10le" -y -c:v av1_nvenc
 -cq 20 nlmeans.mp4
 }}}
