Build a UGC Live Streaming App with Amazon IVS: Displaying Stream Credentials (Lesson 3.1)
Welcome to Lesson 3.1 in this series where we're looking at building a web based user-generated content live streaming application with Amazon IVS. This entire series is available in video format on the AWS Developers YouTube channel and all of the code related to the sample application used in this series can be viewed on GitHub. Refer to the links at the end of the post for more information.

In this lesson, we will look at how StreamCat retrieves and displays a user's
Channel credentials. These credentials allow a user to live stream directly to their dedicated Amazon IVS channel from third-party streaming software.If you recall from lesson 2.3, each
Channel has a property called ingestEndpoint and another called streamKey. 
These two properties are used by third-party streaming software to broadcast a live stream. For example, here's a dialog from the popular program OBS showing the required inputs.
So in order to stream to this Amazon IVS channel, we have to retrieve and display these two values from the user's channel.
When we created the
Channel model, we persisted the ingestEndpoint directly into the database. Because this value represents the endpoint for both RTMP and WebRTC ingest, it lacks a protocol prefix. Here's an example of the value that is persisted for each channel: f99084460c35.global-contribute.live-video.net. To display an rtmps URL - the format most commonly accepted by third-party streaming software - we can add a computed property to the Channel.Within the user's dashboard, we can retrieve the current user's channel information, and render it to the view.
At this point, a StreamCat user can copy and paste the ingest endpoint and stream key into third-party broadcasting software and start a live stream. We'll see how to create a playback experience (IE: the user's public facing "channel") in a future lesson in this course.
In this lesson, we learned how to retrieve and display a user's
ingestEndpoint and streamKeyAny opinions in this post are those of the individual author and may not reflect the opinions of AWS.
