Feature Request: yadif_cuda and vamf support

[alturismo]

Hi, may a chance to get those features enabled by default ?

mainly cuda-llva to get yadif_cuda and scale_cuda up and running.

vamf would be "nice to have" ;)

thanks ahead

Hello !

Not familiar how to get those features added ? Are they flag on the ffmpeg compile step, do you have any documentation ?

good morning, i thought this had been already covered here as its a main nice feature, as sample the yadif_cuda is ~ 2x faster then yadif with no real loss in quality.

https://github.com/jrottenberg/ffmpeg/pull/319

now i saw the flag wasnt set, --enable-cuda-llvm, but i guess there is a bit more todo ... when i try to build with this flag.

about vamf support, just a neat feature to compute a quality score from the encoded video's, not really a major thing

as sample https://ottverse.com/vmaf-ffmpeg-ubuntu-compilation-installation-usage-guide/

thanks for taking a look
