Thank you for all the support. Please can you help with this
I am getting the following error when I run with .y4m
ffmpeg_quality_metrics.ffmpeg_quality_metrics.FfmpegQualityMetricsError: Your ffmpeg version does not have the filter 'libvmaf'

I verified while building ffmpeg that enable libvmaf

Please refer the output ffmpeg -h

You have not provided the debug output (with -v). Please edit your issue to include it, or post it as a comment.

---

Are you sure you do not have multiple ffmpeg versions installed on your system?

Please check:

which -a ffmpeg

This program chooses the first ffmpeg in your $PATH.

Also check that ffmpeg -filters lists libvmaf.

[kanlions]

I updated the comment. Now I have removed ffmpeg and this git again and still facing the same issues. Dp you recommend a clean build of ffmpeg. I am using the latest one I guess

[slhck]

I don't quite understand why you would remove this project. As I described above, ffmpeg-quality-metrics simply looks for ffmpeg in your $PATH and executes that. Please answer the questions I asked above to help me troubleshoot this:

1. Did you check which -a ffmpeg — and what did it output?
2. Did running ffmpeg -filters print libvmaf?

To get an ffmpeg build with libvmaf support, you have several options. You just say you are using “the latest one” but it's unclear from where you obtained it. My recommendation for a simple setup would be to download the one from here and place the ffmpeg executable in /usr/local/bin:

wget -q https://johnvansickle.com/ffmpeg/builds/ffmpeg-git-amd64-static.tar.xz && \
  tar --strip-components 1 -xf ffmpeg-git-amd64-static.tar.xz && \
  sudo cp ffmpeg /usr/local/bin/ffmpeg && \
  sudo cp -R model /usr/local/share/ && \
  rm ffmpeg-git-amd64-static.tar.xz

Then check that $PATH contains /usr/local/bin. If it does not, edit your ~/.bashrc and add:

export PATH="/usr/local/bin:$PATH"

After changing the path, reload your shell, then try again.

Apologies but since I thought its a standard procedure to install ffmpeg and ffmpeg-quality-metrics so tried installing again. I never expected to run into troubles when command line vmaf works.
also i have /usr/local/bin/ffmpeg deom which -a ffmpeg.
I will follow your guidelines now. For installation I followed the following link.

https://github.com/Netflix/vmaf/blob/master/resource/doc/ffmpeg.md

I appreciate all the support from your.

The VMAF docs you linked are not quite complete, as they don't tell you that you should move the built ffmpeg executable somewhere into your PATH.

Just go with the static johnvansickle builds if you don't care about getting the absolutely latest VMAF version.

Or copy the bulit ffmpeg executable (after the make) step into a directory in the PATH.
