Open Broadcaster Software







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 (RTMP) and can be sent to any RTMP supporting destination, including many presets for streaming websites such as Youtube Twitch.tv and Facebook.[5]
For video encoding, OBS is capable of using the x264 free software library,[6] Intel Quick Sync VideoNvidia 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.
The main user interface is organized into 4 sections: Scenes, Sources, Audio mixer, Transitions and Controls. Scenes are groups of sources like live and recorded video, text and audio. The mixer panel lets the user mute the audio, and adjust the volume through virtual faders, and apply effects by pressing the cogwheel next to the mute button. The control panel has options for starting/stopping a stream or recording, a button to transform OBS to a more professional Studio Mode (see below), a button for opening the settings menu and a button to exit the program. The upper section has a live video preview, used to monitor and edit the current scene. The user interface can be switched to dark or light theme depending on what the user prefers.
When in studio mode, There are 2 scene preview windows, the left one for modifying and preview of non-active scenes, while the right window is for preview of the active scene. in the middle there is a secondary transition button, allowing for transitioning to the non active scene in the left window.
