OBS Studio (Open Broadcaster Software) is a free, open-source recording and live-streaming software available for Windows, Mac, and Linux. It's one of the most popular tools for creating high-quality live streams on Uscreen.
OBS acts like a switchboard, allowing you to control multiple audio and video sources. It gives you greater control over your live event, including features like:
Overlays and transitions
Multiple camera angles
Screen sharing with audio
Custom graphics and text
Advanced audio mixing

📝 NOTE: Uscreen provides the stream key, player, and CDN delivery. Your encoding setup (OBS settings), audio/video equipment, and internet connection are your responsibility. Our support team can help with Uscreen-side issues (event setup guide, stream key, player behavior), but cannot configure or troubleshoot OBS Studio or other third-party streaming software.

Test your Stream
Before going live, it's crucial to test your stream:
In OBS, click Start Streaming
In Uscreen, navigate to Content > Live Streaming
Select your event and Edit
In the RTMP section, click Test Player
Wait at least 60 seconds to see your content in the test player
💡 TIP: It's a good practice to set up a test stream a day or a few hours before your actual event to troubleshoot any potential issues.
Go Live
Once you've tested your stream and are ready to Go Live:
In OBS Studio, click Start Streaming
In Uscreen, click Start Live Stream
Your stream is now live and visible to your audience
💡 TIP: Start your stream in OBS 30-60 seconds before your actual start time to prevent viewers from seeing a black screen.
End the Stream
When your event is complete:
In Uscreen, click Finish Event
In OBS Studio, click Stop Streaming
⚠️ WARNING: Make sure to stop the stream in both OBS and Uscreen. If you only stop one, the system will continue to create recording fragments.
