Description Lori 2015-03-09 17:44:37 UTC 
Version 2.6 of ffmpeg supports hardware accelerated H.264 encoding with nVidia card from the Fermi and Kepler architectures, see [1].  However, the current ebuild doesn't offer a USE flag to optionally turn this feature on (default off).

Reproducible: Always
Comment 1 Alexis Ballier gentoo-dev 2015-03-11 08:37:45 UTC 
good, but where can i find nvEncodeAPI.h ?
Comment 2 Lori 2015-03-11 12:50:47 UTC 
Hmmm, I guess we need a new ebuild for https://developer.nvidia.com/nvidia-video-codec-sdk :(

ffmeg with nvenc support
Comment 4 Jam 2015-03-31 17:47:55 UTC 
This one seems to work. User needs to manually download sdk from https://developer.nvidia.com/nvidia-video-codec-sdk unpack and place nvEncodeAPI.h  in the ebuild's catalogue.

This is only a temporary solution of course...

    media-video/ffmpeg: Add nvenc useflag to live ebuild. Bug #542726.


finally took time to add nvenc ebuild!
Comment 6 Timo Rothenpieler 2015-10-25 11:05:12 UTC 
The hard dependency on the cuda-toolkit in the new nvenc ebuild seems unneccesary. It only copies some headers around, and ffmpeg doesn't have any external dependencies for nvenc except for a single header.
Comment 7 George Kranis 2015-10-27 15:16:52 UTC 
nvenc use requires --enable-nonfree, otherwise configure fails with
"nvenc is nonfree and --enable-nonfree is not specified"
Comment 8 om3i 2016-01-13 11:06:13 UTC 
Are there plans to add nvenc to non-live ebuilds starting from 2.6? ffmpeg-2.8.4 is out and that's annoying to have so many packages in local overlay.
Comment 9 om3i 2016-01-13 11:08:31 UTC 
Also ffmpeg is famous for breaking api compatibility, so can't really use 9999 version.
