Install OBS-Studio in Ubuntu via PPA:

The software is available in a PPA repository for Ubuntu and derivatives users. Ubuntu 15.10 and Ubuntu 14.04 LTS are supported so far.

1. Add the PPA

Open terminal from Unity Dash, App Launcher, or via Ctrl+Alt+T shortcut keys. When it opens, paste below command and hit enter:

sudo add-apt-repository ppa:obsproject/obs-studio

Type in your password when it asks, no visual feedback so just type in mind, and hit Enter to continue.

2. For Ubuntu 14.04 LTS and derivatives only.

The Software requires ffmpeg which is not included in 14.04’s official repositories. If you don’t have ffmpeg installed, add below PPA via command:

sudo add-apt-repository ppa:kirillshkrogalev/ffmpeg-next

3. After that, search for and install obs-studio via Synaptic Package Manager after clicking the Refresh button.

Or run below commands one by one in terminal:

sudo apt-get update

sudo apt-get install obs-studio

How to Uninstall:

You may remove both PPAs by launching Software & Updates and navigating to Other Software tab, and remove the broadcaster software via Synaptic Package Manager or by running below command in terminal:

sudo apt-get remove obs-studio && sudo apt-get autoremove
