Issue calculating VMAF using libvmaf_cuda

[a-ayad]

I have CUDA 12.8 installed and latest build of VMAF and ffmpeg from source on WSL Ubuntu 22.04

I use the following command

ffmpeg -hwaccel cuda -hwaccel_output_format cuda -codec:v av1_cuvid -i test1.y4m -hwaccel cuda -hwaccel_output_fo rmat cuda -codec:v av1_cuvid -i output.mp4 -filter_complex " [0:v]scale_cuda=format=yuv420p[dis]; \ [1:v]scale_cuda=format=yuv420p[ref]; \ [dis][ref]libvmaf_cuda=log_fmt=json:log_path=output.json " -f null -

and i get the following error:

ffmpeg -hwaccel cuda -hwaccel_output_format cuda -codec:v av1_cuvid -i test1.y4m -hwaccel cuda -hwaccel_output_fo
rmat cuda -codec:v av1_cuvid -i output.mp4 -filter_complex "
