Just following-up to my post... Firstly, my ffmpeg command initializing vulkan was completely wrong. I used: -init_hw_device vulkan but, it should be: -init_hw_device "vulkan=vk:0" -hwaccel vulkan -hwaccel_output_format vulkan or: -init_hw_device "vulkan=vk:0" -filter_hw_device vk Secondarily, l used libplacebo custom shader multiple times, but it seems accept only one, single shader. And this might be the cause of "[mvk-error] VK_ERROR_OUT_OF_DEVICE_MEMORY..." message... Then, I just concatenate each shader using cat command. This seems like worked, but resulting output video have unacceptable artifacts... I confirmed my concatenated shader with mpv player, then found those artifacts exists. They exists even though the shader applied as independent glsl file. So I suspect that Anime4K shader is not usable because of my poor hardware, Apple M2. Or my poor understandings with shader and so on... I'm now trying to use ewa_lanczos to scaling up my input video... If those follow-up have any misunderstandings or any wrong, kindly teach me...
