Quoting: KithopI'm still trying to get the NVENC support to work. Rather, to detect. Managed to hackily build a .deb for Ubuntu 16.04 off the master tree for ffmpeg with --enable-nonfree and --enable-nvenc tacked on the end. Have the required toolkit installed from nVidia, headers symlinked in /usr/local/include ... a bit of futzing around later with it not detecting libva properly (maybe just an issue from when I cloned master?), and I have working ffmpeg .debs!

I installed them! 'ffmpeg --codecs' shows nvenc in the list!

OBS still mocks me with 'Software (x264)' as the only encoder drop down. :( So now I'm thinking, great, do I have to actually build OBS from source too, so it detects my new custom build of ffmpeg? Oh, right, I need all the -dev packages that OBS depends on if I want to bui-

*fliptable* I'm not a developer, but a SysAdmin. This is one time I will say: BSD's ports system makes this so much easier. You pick your poison at configure time, and it always rebuilds from source.

If anyone figures it out, I'd love to know... and no, I can't redistribute the .deb files legally - hence the requirement for non-free. ;/ This is why we can't have nice things, like a PPA with NVENC-enabled ffmpeg builds, unless nVidia relicenses the required libraries.

95%+ sure that my next card (and potentially my next CPU!) are going to be AMD, so here's hoping for some love in the form of, say, AMD VCE support in OBS Studio? ^.^ Especially if it's exposed through the new-and-upcoming open source AMDGPU drivers. I'm so, so sick of binary blobs and stupid license incompatibility issues.

You many need to rebuild OBS. If you have the OBS ppa set up, make sure you have build-essential and debhelper packages installed, then try:
apt-get build-dep obs
This may replace your custom ffmpeg. If it does, reinstall your custom ffmpeg deb package.
apt-get source obs
I don't remember if this will unpack the source tarball for you. If not, unpack it.
Then, navigate to the directory where you just downloaded the OBS source.
dpkg-buildpackage
Assuming all goes well, you should find a .deb package in the source code's parent directory. Install it.

If this doesn't work, you probably need to rebuild ffmpeg, with the "--enable-shared" option. Good luck! If you rebuild ffmpeg, you may need to rebuild OBS, too.

I had this working previously, but after some recent upgrades, everything broke. Rather than fix it, I just switched to Arch, where all the necessary goodies were in the AUR, and it built and compiled effortlessly. I'm serious. Switching to Arch was actually less hassle for me than getting it working on Ubuntu.

(NOTE: I'm not interested in getting involved in any distro wars. They're both good distros, with their own strengths and weaknesses, and I use each of them regularly. Manjaro is a nice compromise. It feels like reminiscent of Mint, but it's a rolling release and uses Arch's package management.)
