Topic: Possible to use AviSynthFilter with DeoVR or Whirligig?

Is it possible to use AviSynthFilter (instead of ffdshow) with DeoVR or Whirlgig?

Also, do I need to use DXVA2 (copy-back) with LAV Video?  ...or can I use DXVA2 (native)?

Re: Possible to use AviSynthFilter with DeoVR or Whirligig?

You need DXVA2 (copy-back) to return frames from GPU to system memory. Otherwise SVP can't get them.
DXVA2 (native) process frames inside GPU and do not copy them to memory.

About DeoVR and Vhirlgig. These players needs Codec Tweak Tool for tuning: https://www.svp-team.com/wiki/SVP:Whirligig
And Codec Tweak Tool can't give you ability to select AviSynth Filter instead ffdShow.
So, for now answer is NO. But I think it is possible to find another way to select AviSynth Filter. We need some searching and investigating...

not possible until the Whirligig author add Avisynth filter as an option
if you're paid Whirligig user you can ask nim nicely from your side wink

Thanks for the replies.

@Mag79 - I don't think Codec Tweak Tool works for AviSynth Filter because it's not a video decoder?  ffdshow appears in the list because it's a video decoder (and filter), but please correct me if I'm wrong.

Also, what is required to process or playback 8K video files?

If I use copy-back (DXVA2 or D3D11) the video stutters even without SVP.  My system is an i7-8700k @ 5 GHz with an GTX 3080.
