Right. This filter can do any arbitrary target frame rate, so you shouldn't need to use any other mechanisms. Eg: you can do 24->60 with it and, in theory, you...

I have [added](https://github.com/FFmpeg/FFmpeg/commit/297c36a647cad0f8399ac5f4b533701eb67831fb) support for `source_fps` expressions.

Actually, I'm reopening this just to improve visibility for anyone who wants to use this.

I cannot provide a detailed guide on how to ensure you have all the required dependencies, but for this specific case, you must place `NvOFFRUC.h` in the `libavfilter/` directory next...

Yes, you do need to modify it, as documented in the code: https://github.com/philipl/FFmpeg/blob/nvoffruc/libavfilter/vf_nvoffruc.c#L42

That suggests you might have mangled something. Line 215 in the original flle in innocuous. make sure you didn't actually delete something else.

I'm afraid I don't know enough about the windows build to help with that. Certainly you should modify NvOFFRUC.h rather than rename the file - which might cause problems elsewhere....

No, but unfortunately, I am reminded of https://github.com/philipl/FFmpeg/blob/nvoffruc/libavfilter/vf_nvoffruc.c#L318 There is no logic for doing dynamic symbol loading on Windows.It's not particularly difficult as you can use `compat/w32dlfcn.h` to probably make...

> I think another approach was the vapoursynth route which reminds me of an old project with the legacy NV Optical Flow [vapoursynth-nvof](https://bitbucket.org/mystery_keeper/vapoursynth-nvof/src/master/) but the maintainer @mystery-keeper never upgraded that...

I get this with mpv. It seems harmless in that context but here's what I see (not much it seems) ``` $ NVD_LOG=1 mpv /storage/video/test-patterns/juddertest_60.mp4 --profile=nvidia-vaapi --pause [auto_hwdec] Applying profile:...
