Feature Request: MS-SSIM #89

Closed ls-milkyway closed 2 years ago

ls-milkyway commented 2 years ago

MS-SSIM is better evaluation than SSIM hence please include it in FFmetrics, It is available in ffmpeg as ffmpeg -i distorted.mpg -i reference.mpg -lavfi libvmaf='feature=name=ms_ssim' -f null -

You can keep PSNR; SSIM; MS-SSIM & VMAF OR I guess PSNR; MS-SSIM; VMAF because MS-SSIM is greater form of a SSIM type video quality evaluation...thanks.

I'd say I do not like the libvmaf implementation at all. They've already changed their API a few times over relatively short period of time and do not have some very basic features (for example: feature detection and output to stdout). So at this stage I do not have plans to support MS-SSIM through libvmaf. May be later. Sorry.

P.S. if the MS-SSIM output format is the same, one may re-define "Filter" in FFMetrics.conf and calculate MS-SSIM instead of VMAF.

Yep, I understand .......even I have faced huge problems in maintaining some projects...specially when their json input structure was changed by the third party API without notice ...literally made my life ..hell...
