Hello. Currently ffmpeg doesn't provide a way to enable its CUDA support. AFAIU CUDA support is not even automagic, but have to be enabled explicitly. This is bad for users with such hardware, since they cannot get hwaccel and other nice things with stock ebuild even through automagic. CUDA support in ffmpeg can be optionally used by media-video/mpv starting with the next release. Currently this mpv feature has to be forcibly disabled. Please provide 'cuda' USE to control ffmpeg's CUDA support.
Hi, FFMPEG 3.2.2 has '--enable-cuda' configure option, which is disabled by default, and there's no USE flag to enable it. Is it possible to add a USE or something for CUDA? Regards, Alex
a tested patch would definitely help there (I dont have capable hw available I think atm), even better if this is a github pr for 3.2.x and 9999
I have gotten CUDA decoding to work with both ffmpeg and mpv locally via the following changes: 1. EXTRA_FFMPEG_CONF="--enable-cuda --enable-cuvid --enable-nonfree" in package.env 2. CFLAGS="${CFLAGS} -I/opt/cuda/include" for both mpv and ffmpeg Adding the former as use flags should be trivial, but the more concerning issue is the fact that dev-utils/nvidia-cuda-toolkit does not seem to add itself to the include path correctly.

Hi, I took a stab at it and got it working incl. support for hardened(pax). https://startux.de/git/quarks.git/blob/327e47e33028181c62e5ff58363dd59fcb1e8548:/media-video/ffmpeg/ffmpeg-3.2.2-r1.ebuild Diff to upstream 3.2.2 ebuild. --- /usr/portage/media-video/ffmpeg/ffmpeg-3.2.2.ebuild 2017-01-06 01:17:31.000000000 -0800 +++ ffmpeg/ffmpeg-3.2.2-r1.ebuild 2017-01-09 13:13:06.167430284 -0800 @@ -21,7 +21,7 @@ EGIT_REPO_URI="git://source.ffmpeg.org/ffmpeg.git" fi -inherit eutils flag-o-matic multilib multilib-minimal toolchain-funcs ${SCM} +inherit eutils flag-o-matic multilib multilib-minimal pax-utils toolchain-funcs ${SCM} DESCRIPTION="Complete solution to record, convert and stream audio and video.

If someone could make a full patched 9999.ebuild -- I could test it with GTX 660 (and probably 1060 too). Regards, Alex
