Connect OBS (recommended)
In your Live Room on the Seller Portal, choose OBS Integration and follow the steps shown there.
Manual setup
Only use this if the integration doesn't work for you:
In OBS, go to Settings → Stream and choose Custom as the service.
Copy the Stream URL and Stream Key from your Live Room in the Seller Portal.
Copy the highlighted video and output settings below exactly.
Go live
Click Start Streaming in OBS.
Click Stop Streaming when you're done.
Tips for a stable stream
Keep your setup simple: fewer cables, adapters and devices means fewer things can go wrong.
Use direct cables, for example Micro HDMI to HDMI, and avoid adapters. They can cause lag, sync issues and overheating.
Use a powered hub that plugs into the mains, for example the ATEM Mini Pro.
Use a powerful computer. Lower-spec machines can drop frames or crash.
Use good lighting, and set exposure and white balance before you go live.
Turn on OBS noise suppression if needed, and don't capture the same audio source twice.
