Open Broadcaster Software (also known as OBS) is a free and open source streaming and recording program maintained by the OBS Project. The program has support for Windows 7 and later, OS X 10.8 and later, and Linux Ubuntu 14.04 and later.

Overview

Open Broadcaster Software is a free and open source software suite for recording and live streaming. Written in C and C++, OBS provides real-time source and device capture, scene composition, encoding, recording and broadcasting. Transmission of data is primarily done via the Real Time Messaging Protocol and can be sent to any RTMP supporting destination (e.g. YouTube) including many presets for streaming websites such as Twitch.tv and DailyMotion.[5][6]

For video encoding, OBS is capable of using the x264 free software library,[7] Intel Quick Sync Video, Nvidia NVENC and the AMD Video Coding Engine to encode video streams into the H.264/MPEG-4 AVC format and the H.265/HEVC format. Audio can be encoded using either the MP3 or AAC codecs. Advanced users can choose to use any codecs and containers available in libavcodec / libavformat as well as output the stream to a custom ffmpeg URL.

History

Open Broadcaster Software started out as a small project created by Hugh "Jim" Bailey, but quickly grew with the help of many online collaborators working both to improve OBS and spread the knowledge about the program. In 2014,[8] development started on a rewritten version known as OBS Multiplatform (later renamed OBS Studio) for multiplatform support, a more thorough feature set, and a more powerful API.[9] As of v18.0.1 of OBS Studio, OBS Classic is no longer supported due to the former reaching near-full feature parity with the latter, though the download for Classic is still available.[10]

Plug-ins

Open Broadcaster Software supports a variety of plug-ins[3] to extend its functionality. Plug-ins are loaded as native code DLL files,[11] although a wrapper plug-in[12] is available that allows hosting of plug-ins written in the .NET Framework.
