Using the command:
time -p ffmpeg -init_hw_device vulkan=vulkan -filter_hw_device vulkan
-hwaccel vulkan -i hdr_02.mp4 -vf
libplacebo=format=yuv444p:w=1920:h=1080:force_original_aspect_ratio=decrease:normalize_sar=true:upscaler=ewa_lanczos:downscaler=ewa_lanczos:colorspace=bt709:color_primaries=bt709:color_trc=bt709:range=tv
-c:a copy -c:v libx264 -f mp4 -benchmark 2k.mp4

It's all OK.

But this is a command I had already tried.
I don't want to put ffmpeg-git on my system. Is it useless to compile
ffmpeg-git in CinGG? Can ffv1_vulkan be made to work inside CinGG?

I can confirm the same "Unrecognized option 'slices_v' " message from my current ffmpeg-7- 7.1.1-1699.4.pm.2 (Packman) on openSUSE Slowroll.
And the ffv1_vulkan encoder is not available:

ffmpeg -hide_banner -encoders | grep vulkan
V....D h264_vulkan H.264/AVC (Vulkan) (codec h264)
V....D hevc_vulkan H.265/HEVC (Vulkan) (codec hevc)
