FFmpeg deinterlacing filter yadif_cuda not available?

Question

FFmpeg reports "No such filter: 'yadif_cuda" for both the release build and the static build. FFmpeg Documentation has no stipulations.

$ ffmpeg -loglevel debug -ss 01:16:20 -i Hi8_02.dv -t 10 -vf "yadif_cuda, scale=hd720:flags=bilinear" -c:v dnxhd -profile:v dnxhr_sq Hi8_02test.mov

Answer 1

The static build doesn't have that filter, as it requires linking against the NVIDIA SDK, which is nonfree software, so it cannot be redistributed. Also it wouldn't much sense to bundle it for users without an NVIDIA GPU.

You therefore have to:

• install the NVIDIA SDK
• build FFmpeg yourself

to get support for that filter plus other NVENC/NVDEC features.
