Comment (by XuGuangxin):

 Hi aphysically,
 Your steps 2 proved vaapi encoder is ok.
 and your step 3 is not related to vaapi, right?

 could you use the following command line to prove it's a vulkan filter's
 issue?

 LIBVA_DRIVER_NAME=i965 ffmpeg -loglevel debug -hide_banner
 "${vulkanvaapi_flags[@]}" -i vaapiencode.mkv -c:v libx264 -r:v 30
 -profile:v high -preset veryfast -y vaapiouts.mkv

 thanks
