psnr (ssim) use pipe #90

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago

When evaluating the quality of webp, a tool that can measure quality is useful.
At google we use psnr, which does ssim and others.  But it requires 2 yuv files.
When the 2 yuv files exceed your disk space, its not possible
Can you make psnr tool, or something like it, accept a piped input?

We're talking files approaching 1 TB and multiple transcodes, so today, thats a 
size and performance limitation.

I think this was misplaced.
libyuv now provides this tool:
