[FFmpeg-devel] [PATCH] avfilter: add ANSNR filter

Fri Mar 31 00:06:36 EEST 2017
A new filter ANSNR is added. libavfilter/Makefile is changed.
Run 'ffmpeg -i input1 -i input2 -lavfi ansnr -f null -' to get an overall score while per-frame value is stored but not printed.
This implementation is for constructing the vmaf filter later since ANSNR is one of individual tools used in vmaf.
