 Summary of the bug:
 How to reproduce:
 {{{
 ffmpeg -init_hw_device vulkan=vul:0 -filter_hw_device vul -i
 /home/wenbin/workplace/test_video/1080P_THE_HOBIT3_1920x1080_2700frames.264
 -vf "hwupload=extra_hw_frames=16,scale_vulkan=w=1920:h=1080" -f null -
 }}}
 Error occurs at
 https://github.com/FFmpeg/FFmpeg/blob/2fac1e370c9cf48b2e9d4a7f2c0d7236017f9bbe/libavutil/hwcontext_vulkan.c#L1018
 The CreateCommandPool function is not loaded, so the function pointer is
 NULL.

 I think the code in
 https://github.com/FFmpeg/FFmpeg/blob/2fac1e370c9cf48b2e9d4a7f2c0d7236017f9bbe/libavutil/hwcontext_vulkan.c#L1352
 should be changed to
 {{{
 err = load_functions(ctx, 1, 1);
 }}}
