With ffmpeg encoded video (HEVC or H264) : VMAF nan
3 juin 2020, par ringola27I am able to calculate VMAF for the videos encoded with VP9 but not for the videos encoded with HEVC and H264.



I am getting the output :



VMAF score: nan


For the Command Line : 

ffmpeg -i netflix200kHEVC.mp4 -i netflixboxing.y4m -lavfi "libvmaf=model_path=/usr/local/share/model/vmaf_v0.6.1.pkl" -f null -


Do you know this kind of problem ? How can I solve it ?



ffmpeg -i netflix200kHEVC.mp4 -i netflixboxing.y4m -lavfi "libvmaf=model_path=/usr/local/share/model/vmaf_v0.6.1.pkl" -f null -

[libvmaf @ 0x7ff05a61b300] VMAF score: nan

Calculate VMAF for HEVC or H264 with ffmpeg
3 juin 2020, par ringola27I am able to calculate VMAF for the videos encoded with VP9 but not for the videos encoded with HEVC and H264.



I am getting the output :



VMAF score: nan


For the Command Line : 

ffmpeg -i netflix200kHEVC.mp4 -i netflixboxing.y4m -lavfi "libvmaf=model_path=/usr/local/share/model/vmaf_v0.6.1.pkl" -f null -


Do you know this kind of problem ? How can I solve it ?

create an Json file as an output from a ffmpeg command line
22 juin 2020, par ringola27I am trying to put the output I get from a ffmpeg command into a json file.
So I tried :


ffmpeg -i 2.y4m -i netflixboxing.y4m -lavfi "libvmaf=model_path=/usr/local/share/model/vmaf_v0.6.1.pkl" -f null - > out.json 


I get an empty json file. Do i have to specify which information I need in my json file ?


I hope someone can help me.
