OBS Studio (also Open Broadcaster Software or OBS, for short) is a free and open-source app for screencasting and live streaming. Written in C/C++ and built with Qt, OBS Studio provides real-time capture, scene composition, recording, encoding, and broadcasting via Real Time Messaging Protocol (RTMP), HLS, SRT, RIST or WebRTC. It can stream videos to any RTMP-supporting destination, including YouTube, Twitch, Instagram and Facebook.[11]
For video encoding, OBS Studio can use the x264 transcoder,[12] Intel Quick Sync Video, Nvidia NVENC and the AMD Video Coding Engine to encode video streams into the H.264/MPEG-4 AVC or H.265/HEVC formats.[13] It can encode multiple tracks of audio in the AAC format. More experienced users can choose any codecs and containers available in libavcodec and libavformat, or output the stream to a custom FFmpeg URL.[14]
OBS Studio also supports plug-ins to extend its functionality.[15]
