OBS Studio 28.1, the streaming, compositing and video recording suite, is now available. 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.
Key changes:
- Added the ability to use the NVENC encoders provided in NVIDIA video cards for hardware acceleration of video encoding in AV1 format on the Windows platform. The encoder supports NV12 and P010 color formats and is available for NVIDIA RTX 40 series graphics cards.
- Updated presets for NVENC encoders. Presets are divided into three different classes: Preset, Tuning and Multipass. The Preset class offers settings for quality levels P1-P7 (the lower the level, the lower the quality). The Tuning class is used to prioritize between delays and quality (suggested modes are high quality, low delays, and very low delays). The Multipass class determines whether to use the second pass when encoding (proposed modes: disable the second pass, quarter resolution and full resolution).
- The "Always on Top" option has been moved to the View menu.
- Provided the ability to select a specific source for the virtual camera.
- Fixed crashes when manipulating the virtual camera.
- In studio mode, mixing has been adjusted.
- Fixed screen capture issues with Direct3D 9 games on Windows 11 22H2.
