I have problems with slice_v:

RADV_PERFTEST=video_decode,video_encode (doesn't work inline with ffmpeg command, don't know why) 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 ffv1_vulkan -slicecrc 0 -level 4 -strict -2 -async_depth 5 -slices_v 32 -slices_h 32 -f matroska -benchmark /dev/null

Unrecognized option 'slices_v'. Error splitting the argument list: Option not found real 0,05 user 0,02 sys 0,01

Eliminating the options slice_ e slice_h ottengo:

[vost#0:0 @ 0x593c19344240] Unknown encoder 'ffv1_vulkan' [vost#0:0 @ 0x593c19344240] Error selecting an encoder Error opening output file /dev/null. Error opening output files: Encoder not found bench: maxrss=158204KiB real 0,09 user 0,04 sys 0,01

I guess you have a preset that I don't have? Did you use ffmpeg-git?

yes, this line was done with ffmpeg git. You can delete those options and see if it runs

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.

replace -c:v x264 with -c:v ffv1_vulkan , if you want to test this specific encoder, only in ffmpeg.git. Or just do not test anything if you do not want ;) I am trying to get multithreaded swscale working but it keep segfaulting, so sorry .... 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 think encoders are simpler to get working, but you can try to recompile cingg with ffmpeg git and see if ffv1_vulkan appears in thirdparty/ffmpeg.git/ffmpeg -encoders | grep vulkan do not forgot to patch cingg with my ffmpeg8 patch, and remove two thirdparty/src/ffmpeg.git patches that fail to compile (patch2 for sure and another one). Again, you can just compile and run ffmpeg from git in your home directory, no need to install it system wide.
