OBS Studio, free and open-source live streaming and screen recording software, reached 21.1 release a day ago. Here’s how to install it in Ubuntu 18.04, Ubuntu 17.10, Ubuntu 16.04, and/or Ubuntu 14.04.

Changes OBS Studio 21.1 include:

• Updated the Browser source to Chromium 63 with a few fixes and APNG (animated PNG) image files support.
• Dockable windows can now be nested.
• Updated the program to use the latest Microsoft development toolchain (Visual Studio 2017) for the Windows version.
• Changed log file uploading to hastebin (for now) instead of anonymous github gists due to github removing anonymous gist support.
• Fixed an issue where the AMD encoder wouldn’t show up for some people since 21.0.
• And various other fixes. See the release page.
