Crate viser_quality 

Video quality measurement for the viser video-encoding-optimizer workspace.

Computes VMAF, PSNR, SSIM, SSIMULACRA2, and butteraugli scores between a reference and a distorted video. VMAF/PSNR/SSIM use FFmpeg’s libvmaf filter, while SSIMULACRA2 and butteraugli shell out to their CLI tools on extracted PNG frames. See measure for the entry point.
