Dear all,
I made a new build, took the rc5 branch which was finally vs2019 friendly. I was so happy upon that that I put some effort into implementing new color spaces in the core. (after having my Avisynth filter work again on this new codebase)
https://github.com/pinterf/xy-VSFilt.../tag/3.2.0.804
Tested only from Avisynth TextSub filter, as my primary goal was this. Supports native YV16, YV24, and 10 and 16 bit 4:2:2 formats (internally P210 and P216). What ever it does outside Avisynth, I don't know.
