Streaming software configuration

Agora recommends using one of the following stream-pushing software to push streams to Broadcast Streaming:

• OBS (Open Broadcaster Software), which supports macOS, Windows, and Linux.
• XSplit Broadcaster, which supports Windows.

This page takes OBS as an example to show the configuration of the stream-pushing software.

• OBS is installed.
• The stream-pushing domain name and the stream-playing domain name are configured. The domain name configuration function is in beta. Contact support@agora.io before using it.

Following these steps to configure stream-pushing settings:

1. Get the URL for pushing a stream, see URL Construction.
2. Open OBS, and click the Settings button in the widget list in the bottom right corner.
3. Click Stream in the left navigation menu in the Settings window, and choose Custom... in Service.
4. Fill in the Server and Stream key in accordance with the URL for pushing a stream, as shown in the following figure: For example, if the URL is rtmp://push.agora.io/live/test?ts=1635004800&sign=95b0a9970c593819, the settings are as follows:
   • Server: rtmp://push.agora.io/live
   • Stream key: test?ts=1635004800&sign=95b0a9970c593819
5. Click OK to save the settings.
