maybe you can add a fate test
I understand my colleague (who supports me on this) right, he's still looking into how to do that. But to have some quick progress on your other comments:
libavfilter/vf_xpsnr.c:38:10: fatal error: internal.h: No such file or directory 38 | #include "internal.h"
Thanks, fixed in v4 (attached).
the casts are unneeded
Thanks, fixed in v4.
av_free*(NULL) is safe
Thanks, fixed in v4.

This is a continuation of last year's version of this filter patch, see also
https://ffmpeg.org/pipermail/ffmpeg-devel/2023-January/305517.html
It includes a fix in one of the stride variables and some cleanup in order
to adhere even more to the FFmpeg coding guidelines.
