OBS Studio 27.2 is now available for streaming, compositing and video recording. The code is written in C/C++ and distributed under the GPLv2 license. Builds are generated for Linux, Windows and macOS.
The development goal of OBS Studio was to create a portable version of the Open Broadcaster Software (OBS Classic) application that is not tied to the Windows platform, supports OpenGL and is extensible through plugins. The difference is also the use of a modular architecture, which implies the separation of the interface and the core of the program. Supports transcoding of source streams, capturing video during games and streaming to Twitch, Facebook Gaming, YouTube, DailyMotion, Hitbox and other services. To ensure high performance, hardware acceleration mechanisms (eg NVENC and VAAPI) can be used.
Support is provided for compositing with building a scene based on arbitrary video streams, data from web cameras, video capture cards, images, text, the contents of application windows or the entire screen. During the broadcast, switching between several predefined scene options is allowed (for example, to switch views with an emphasis on the screen content and the image from the webcam). The program also provides tools for audio mixing, filtering with VST plugins, volume leveling and noise suppression.
In the new version:
- Integration with AJA devices is provided, which can now be used as a source and output device for video.
- The version of the Chromium engine has been updated (from version 75 to 95) in the implementation of the broadcast source based on the browser (Browser Source).
- Added the ability to set different mixing modes of broadcast sources through the context menu called by right-clicking the mouse.
- Added experimental AOM AV1 and SVT-AV1 encoders for AV1 format.
- Added hotkeys for updating the broadcast source based on the browser, searching for filters and identifying duplicates.
- Added support for RIST (Reliable Internet Stream Transport) protocol.
- Added a framework to provide background processing of hotkeys in Wayland-based environments.
- Improved stability of PipeWire screen capture on multi-GPU systems.
- Added a setting to automatically hide OBS program interface elements when capturing screen content.
- For the Linux platform, official support for Flatpak packages has been provided.
