To show a live broadcast in your app, use the streaming service's supported embed player. The service handles the stream; your app provides the page around it.
Add the player
Get the provider's embed instructions for the broadcast. Ask the builder to add the player to one page, with a useful message when the stream is offline. Share the public embed URL or snippet, not the account's secret credentials.
Check playback on your live app address after publishing. If you use a custom domain, add that address to any allowed-domain list required by the video provider. See Videos blocked on your custom domain.
What this does not set up
Embedding a player does not create a broadcasting studio, video-call service, recording service or private streaming subscription. Availability, recording, viewer limits and charges depend on the provider and your account there. Verify those before choosing it.
If the stream is paid content, protecting the surrounding page alone may not protect a shareable video URL. Use the provider's access controls as well as your app's server-side membership checks.
Builder changes use credits. The streaming provider bills its own service.
