* [FFmpeg-devel] [PATCH 1/2] Add dirac vulkan hwaccel usage to diracdec.c

  To: ffmpeg-devel; +Cc: Petro Mozil

This patch adds a vc2 hwaccel to ffmpeg.
Tested on ffmpeg vc encoder and vc2-conformance software.

Here is a set of commands to verify correctness

# Encode vid as vc2
ffmpeg -i <in-file> -vcodec vc2 input.vc2

# Decode with hwaccel
ffmpeg -init_hw_device "vulkan=vk:0" -hwaccel vulkan -i input.vc2 output.mkv

# Decode without hwaccel
ffmpeg -i input.vc2 output.mkv

RE: [PATCH] Move vulkan_spirv.h and deps to lavutil

Moved spirv_compiler into lavutil to avoid any linking errors.
It's now used in lavc and lavfi, should probably be moved to lavutil
