OBS Studio (a rewrite of the original Open Broadcaster) is a comprehensive open-source package for video recording and live streaming.
The program supports multiple sources, including media files, games, web pages, application windows, webcams, your desktop, microphone and more.
These sources can be combined. For example, you could include a web development tool, a browser window with a live preview of the site you're updating, and a microphone to tell the viewers what you're doing.
A Record option can save your show/ demonstration/ game/ presentation as an FLV/ MP4/ MOV/ TS/ M3U8 video with your choice of encoder and settings.
Alternatively, there's support for live streaming via Twitch, YouTube, hitbox.tv, DailyMotion, beam.tv, Livecoding.tv, Facebook Live or Restream.io.
The program doesn't make much of an effort to lead you through all this, but it doesn't take long to figure out the basics. Add a source, explore the settings, click Start Recording and check the video results.
What's new in 25.0.1 (see changelog for more)?
- Fixed some FLV files not playing back properly with the media source
- Fixed two crashes with the browser source
- Fixed the names of monitors not showing up when using projectors
- Fixed a crash with window capture
- Fixed an issue where the preview would be stuck as disabled when starting the program minimized to tray
- Fixed an issue where NVENC wasn't showing up for users on Linux (sorry about that, that was my fault -Jim)
- Fixed a bug where certain games (particularly "Don't Starve Together") wouldn't capture with game capture anymore
OBS Studio could be easier to use, but you'll soon learn the basics, and overall it offers plenty of video recording/ streaming power.
