[Cin] Tried ffv1_vulkan ....

[Andrea paz]

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

Eliminating the options slice_ e slice_h ottengo:

[vost#0:0 @ 0x593c19344240] Unknown encoder 'ffv1_vulkan'
[vost#0:0 @ 0x593c19344240] Error selecting an encoder

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