This is obs-studio compiled with a few extra add-ons:

(1) browser source plugin: https://github.com/obsproject/obs-browser

(2) hevc-vaapi encoder support: https://github.com/obsproject/obs-studio/pull/2246

(3) game-capture plugin: https://github.com/nowrep/obs-vkcapture/

Note, you -will- need additional packages from here for game-capture to work:

https://copr.fedorainfracloud.org/coprs/gloriouseggroll/obs-studio-gamecapture/

If you do not want to build this, I host a fedora-compatible repository for it here:

sudo vim /etc/yum.repos.d/obs-studio-nobara.repo

[nobara-obs-studio]
name=nobara-obs-studio
#baseurl=https://www.nobaraproject.org/repo/fedora/$releasever/$basearch/obs-studio-nobara
mirrorlist=https://www.nobaraproject.org/mirrorlist-nobara-obs-studio
type=rpm-md
skip_if_unavailable=True
gpgcheck=1
gpgkey=https://www.nobaraproject.org/repo/nobara/pubkey.gpg
repo_gpgcheck=0
enabled=1
enabled_metadata=1

Then update with:

sudo dnf update obs-studio --refresh

or install with:

sudo dnf install obs-studio

Build instructions:

$ sudo dnf install mock pykickstart
$ sudo usermod -a -G mock <user>
$ mock -r /etc/mock --init
$ sudo setenforce 0
$ mock -r nobara-36-x86_64.cfg --rebuild --enable-network *.src.rpm
$ mv /var/lib/mock/nobara-36-x86_64/result/*.rpm /path/to/some/folder/
$ exit
$ mock -r ./nobara-36-x86_64.cfg --scrub=all
$ sudo setenforce 1

Finished! Packages will be in whatever folder you chose for /path/to/some/folder/

Install instructions:

$ cd /path/to/some/folder/
$ yum install obs-studio-2*.rpm

Upgrade instructions:

$ cd /path/to/some/folder/
$ yum upgrade *.rpm

IMPORTANT NOTES:

• Game capture does -not- work without the additional obs-studio-gamecapture package. You will need this:

https://copr.fedorainfracloud.org/coprs/gloriouseggroll/obs-studio-gamecapture/

• Once the gamecapture packages have been installed, you can capture most games using:

obs-gamecapture somegame

For example with steam games in the launch options for the game:

obs-gamecapture %COMMAND%

Then add 'Game Capture' as a source in OBS.

This works for vulkan + opengl and 64 + 32 bit games.

Known Issues

• The vulkan capture -only- works on AMD due to Nvidia not having VK_EXT_external_memory_dma_buf in their drivers.

Troubleshooting

Cannot create EGLImage: Arguments are inconsistent

If you get this error with Vulkan capture, try starting the game with OBS_VKCAPTURE_LINEAR=1 environment variable.

No Game Capture source available in OBS

If you are on X11, make sure you run OBS with EGL enabled: OBS_USE_EGL=1 obs.
