Build a Live Broadcasting Web App

In a previous post we built a group video chat app similar to a Google Hangouts/Meet. Now we want to build something more akin to Instagram Live. When building a live broadcasting web-app, the architecture is similar to that of a communication web-app, except with a slight twist.To get more news about moonlive, you can visit official website.
For the sake of simplicity, this tutorial will walk through the process of creating a “one-to-many” live broadcasting web-app similar to Facebook and Youtube Live. The web-app will allow a single broadcaster to stream their video feed to a multi-person audience. This project can be extended to support “many-to-many” broadcasting, where multiple broadcasters are streaming to the same audience.In “Building a Group Video Chat Web-App,” the build conformed to the communication scenario, where every user in the channel has the ability to broadcast their audio and video streams.
In this project we will be implementing a broadcasting scenario, where there is a mix of users. Some users in the channel are broadcasting (broadcasters) their camera streams and other users that will be watching the content streamed by the “broadcasters” (audience).
In this case we need to limit the broadcasting capability to specific users while allowing all other users are in the audience they will only consume the broadcaster stream(s).
The graphic above helps us to visualize the flow of our broadcaster web-app. We can see we have to implement two different clients, one for broadcasters and one for the audience. Each client will have a unique interface for each of the user roles (broadcaster/audience) and both will connect to the Agora.io Software Defined Real-Time Network (SD-RTN).
The broadcaster client is almost identical to the client we built for our communication web-app. The main difference being we won’t need to account for other broadcasters, since we’re building this as a one-to-many broadcast.
The above code should look very familiar with a few minor differences — we’ve added some comments to add drop down selectors for the camera and microphone buttons. Along with the button comments there are also two rows of comments for some modal windows that we need to add in.
Let’s start with the camera/mic buttons. We can use button groups to create simple containers for each and we’ll use Agora.io’s SDK to get the input devices and populate these containers. This will give the broadcaster the ability to switch their camera and microphone to any media device connected to their computer/tablet/phone.
Now we are ready to add in our models for configuring the settings for pushing our broadcast stream to RTMP servers. I’ll dive into pushing the stream to external servers a little later in the article, for now lets add the modals and input elements.
