Created attachment 586114 [details, diff] ffmpeg-cuda-support.patch ffmpeg 4.2 (and 9999) recently gained support for building CUDA Kernels for various filters via clang. This patch adds the respective useflag and dependency.
Ideally, clang would be in BDEPEND here, since it is run during compilation only. But the ebuild is still EAPI 6.
