It calculates a score.... You have 2 clips, the score tells you by how much the the seconds clips differs from the first one. The VMAF algo tries take the human perception into account. https://en.wikipedia.org/wiki/Video_...essment_Fusion

Very timely for me. Thanks.

I've had mixed results getting yuv422p10le to work correctly with vmafossexec and/or ffmpeg builds with libvmaf. That's probably my fault for trying on Windows, but I was too lazy to try on a Linux VM at the time.

Request: is it possible to print out the aggregate psnr, ssim, ms_ssim scores ? (Currently it's only aggregate vmaf)

Update r2.
  • Scale 10-bit pixel values to 8-bit range for correct score calculation.
  • Use stricter linear frame request since VMAF score will change if frame order is different.
  • Report aggregate PSNR, SSIM, and MS-SSIM scores in addition to VMAF score.

Not possible with the exposed API of libvmaf. Only when all frames are deliverd and processed does the library print the aggregate scores and optionally write the log file. There is no way to access the library's internal data to get the per-frame score and add that to the frame property.
