Running a Test Stream:

1. Set Up a Test Scene:

  • Use OBS Studio or your chosen software encoder to create a test scene with various sources (video, audio, overlays).

2. Check Settings:

  • Ensure your output settings (resolution, bitrate, FPS) are optimized for streaming.
  • Confirm your audio sources are properly configured and balanced.

3. Start Streaming in Test Mode:

  • In OBS Studio, use the "Start Streaming" option but select "Start Streaming (Studio Mode)" or a test mode if available in your software.
  • This sends your stream to the platform but doesn't make it public, allowing you to verify without your audience seeing.

4. Monitor Stream Health:

  • Use the streaming platform's dashboard or a separate device to view your test stream.
  • Check for issues like video quality, audio clarity, and overall stream stability.

Troubleshooting Common Issues:

1. Dropped Frames:
