[INFO] HLSL Shaders for Avisynth+

[mogobime]

DGDecNV doesn't support high color depth and isn't useful for AMD users

Are you sure? iirc it should support high bit depth on Avisynth+ and Vapoursynth iirc. (not sure whether there are some old restrictions in Hybrid)

I've meant chroma subsampling above yuv420, 10 bit is supported.

c. aside from a few filters (like InpaintDelogo, RemoveDirt,.. ) I don't really thing it's worth using AviSynth nowadays.

I would think about that. It seems so, that avs2yuv64 0.30 and probably ffmpeg, too often perform much better, if AviSynth+ scripts with correctly placed filter prefetches are used, than VapourSynth/Vspipe. I don't know, if these are the best times to trash a potentially more efficient tool (at least at older non high end systems which get fully utilized by AviSynth+).
But I can also understand that you want to focus on one frame server and don't want to realize every filter in the VapourSynth section in the AviSynth section, too.
But since there are - except of FFT3DGPU and KNLMeansCL - almost no GPU filters available, getting a bunch of GPU filters which might all get usable by implementing only one plugin in a clever way (e.g. a possibility to submit the parameters to HLSL filters via a custom field) sounds alluring

Have you actually tried the filter and some of the hslsl filters from https://github.com/zachsaw/MPDN_Extensio...derScripts?

No, not yet. Also no time atm   But there is no hurry...
