 Summary of the bug: not happens with all videos, but in this specifc one
 the ffmpeg crashes with out of memory, my personal GPU has 4GB of VRAM but
 other user reported me that had the same problem with his 12GB VRAM card
 with some videos.
 How to reproduce:
 {{{
 ffmpeg.exe -y -i "test.mkv" -init_hw_device vulkan -vf
 format=yuv420p,hwupload,libplacebo=w=3840:h=2160:upscaler=ewa_lanczos,hwdownload,format=yuv420p
