libavfilter: add a gblur_vulkan filter
This commit adds a powerful and customizable gblur Vulkan filter, which provides a maximum 127x127 kernel size of Gaussian Filter. The size could be adjusted by requirements on quality or performance. The following command is on how to apply gblur_vulkan filter: ffmpeg -init_hw_device vulkan -i input.264 -vf hwupload=extra_hw_frames=16,gblur_vulkan,hwdownload,format=yuv420p output.264 Signed-off-by: Wu Jianhua <jianhua.wu@intel.com>
