Scenes are groups of sources like live and recorded video, text and audio. The main user interface is organized into five sections: scenes, sources, audio mixer, transitions, and controls. Advanced users can choose to use any codecs and containers available in libavcodec and libavformat, as well as output the stream to a custom FFmpeg URL. Multiple tracks of audio can be encoded using the AAC codec. įor video encoding, OBS Studio is capable of using the x264 free software library, 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. Transmission of data is primarily done via the Real Time Messaging Protocol (RTMP) and can be sent to any RTMP supporting destination, including many presets for streaming websites such as YouTube, Twitch, Instagram and Facebook. Written in C, C++ and Qt, OBS provides real-time source and device capture, scene composition, encoding, recording, and broadcasting.
