OBS Studio is free software for video recording and live streaming.
Built with Qt, C and C++ and maintained by the OBS Project, the software provides real-time device capture, scene composition, recording, broadcasting and source capture functions with presets for streaming to popular services such as YouTube, Twitch, Instagram and Facebook.
In 2014, development started on a rewrite of the software, known as OBS Multiplatform, which included a larger feature set, multi-platform support and broader plugin support. As of 2016, the software was rebranded as OBS Studio, with the older OBS Classic being deprecated.

For a standard streaming setup that uses a webcam, PulseAudio, has a NVIDIA graphics card and integrates with major streaming services one might add to /etc/portage/package.use :
media-video/obs-studio lua nvenc pulseaudio speex v4l
emerge --ask media-video/obs-studio
OBS Studio can be paired with JACK, Pulseaudio or PipeWire for audio.
OBS Studio supports integration with VLC media player services. VLC support behaves much like the ordinary media source, however in addition it accepts a list of files to play as well as provides a way to play every path, URL or media source that VLC is able to play.
OBS Studio can be invoked from the command line as follows:
--help, -h: Get list of available commands. --startstreaming: Automatically start streaming. --startrecording: Automatically start recording. --startreplaybuffer: Start replay buffer. --startvirtualcam: Start virtual camera (if available). --collection <string>: Use specific scene collection. --profile <string>: Use specific profile. --scene <string>: Start with specific scene. --studio-mode: Enable studio mode. --minimize-to-tray: Minimize to system tray. --portable, -p: Use portable mode. --multi, -m: Don't warn when launching multiple instances. --verbose: Make log more verbose. --always-on-top: Start in 'always on top' mode. --unfiltered_log: Make log unfiltered. --disable-updater: Disable built-in updater (Windows/Mac only) --disable-high-dpi-scaling: Disable automatic high-DPI scaling --version, -V: Get current version.
emerge --ask --depclean --verbose media-video/obs-studio
If OBS Studio isn't able to record windows or the fullscreen on a Wayland compositor, set the appropriate USE flags and emerge gui-libs/xdg-desktop-portal-wlr.
screencast USE flag for the dependency sys-apps/xdg-desktop-portal, and
pipewire for media-video/obs-studio:
sys-apps/xdg-desktop-portal screencast media-video/obs-studio pipewire
emerge --ask gui-libs/xdg-desktop-portal-wlr
Re-emerge media-video/obs-studio to apply the USE flag change:
emerge --ask media-video/obs-studio
For virtual camera support within OBS Studio, emerge the v4l2loopback kernel module:
emerge --ask media-video/v4l2loopback
For OBS Studio to initialize the kernel module, give it the appropriate permissions, this can be done by running it as root or using a polkit agent.
