Linux
Any installation directions marked Unofficial are not maintained by the OBS Studio author and may not be up to date or stable.
Linux portable mode (all distros)
You can build in portable mode on Linux, which installs all the files to an isolated directory:
mkdir build && cd build
cmake -DUNIX_STRUCTURE=0 \
-DCMAKE_INSTALL_PREFIX="${HOME}/obs-studio-portable" ..
make -j4 && make install
After that you should have a portable install in ~/obs-studio-portable. Change to bin/64bit or bin/32bit and then simply run: ./obs
NOTE: OpenGL 3.2 or later is required to use OBS Studio on Linux. You can check what version of OpenGL is supported by your system by typing the following into the terminal:
glxinfo | grep "OpenGL"
Ubuntu Installation
FFmpeg is required. If you do not have the FFmpeg installed (if you're not sure, then you probably don't have it), you can get it with the following commands:
For Ubuntu 14.04 LTS, FFmpeg is not officially included so you will need a specific PPA:
sudo add-apt-repository ppa:kirillshkrogalev/ffmpeg-next
sudo apt-get update && sudo apt-get install ffmpeg
For Ubuntu 15.04 and following versions, FFmpeg is officially included:
sudo apt-get install ffmpeg
Then you can install OBS with the following commands:
sudo add-apt-repository ppa:obsproject/obs-studio
sudo apt-get update && sudo apt-get install obs-studio
