Hello, ffmpeg experts...
I have 720x480 mpeg2 video. I'd like to upscale this video to 1920x1080, using
Anime4k shader. The ffmpeg command I run is the following:
$ caffeinate -di ffmpeg -init_hw_device vulkan -i C2_t04.mkv -vf
format=yuv420p,hwupload,libplacebo=w=1920:h=1080:custom_shader_path=Anime4K_Clamp_Highlights.glsl,libplacebo=custom_shader_path=Anime4K_Restore_CNN_M.glsl,libplacebo=custom_shader_path=Anime4K_Upscale_CNN_x2_M.glsl,libplacebo=custom_shader_path=Anime4K_AutoDownscalePre_x2.glsl,libplacebo=custom_shader_path=Anime4K_AutoDownscalePre_x4.glsl,libplacebo=custom_shader_path=Anime4K_Upscale_CNN_x2_S.glsl,hwdownload,format=yuv420p
-c:v libx264 -preset medium -crf 18 -level 5.1 -c:a copy -c:s copy
C2_t04_ffmpeg_Anime4K_1080.mkv
And I got "[mvk-error] VK_ERROR_OUT_OF_DEVICE_MEMORY..." message several times
at very first of encoding, but I get resulting output and it seems to be fine...

Is this "[mvk-error] VK_ERROR_OUT_OF_DEVICE_MEMORY..." error can be safely
ignored or is this error harmful?
