avfilter/vf_gblur_vulkan: add sizeV option
This commit added a sizeV option, integrated some identical operations to a separate function, and updated the CGS for horizontal and vertical respectively. The following command is on how to apply sizeV option: ffmpeg -init_hw_device vulkan -i input.264 -vf \ hwupload,gblur_vulkan=size=127:sigma=20:sizeV=3:sigmaV=0.5,hwdownload,format=yuv420p \ -y out.264 Signed-off-by: Wu Jianhua <jianhua.wu@intel.com>
