Media Extensions

A Media Extension is a JavaScript application that is executed within a Twilio MediaProcessor. The Media Extension application can perform specific actions commonly used in a Twilio Live streaming solution, such as joining a Twilio Video Room and formatting the participants' videos in a grid layout.

Twilio currently hosts two Media Extensions: a Video Composer and an Audio Mixer. The Video Composer can be used to stream the contents of a Twilio Video Room in an adaptive video grid layout. The Audio Mixer can be used for an audio-only stream from a Twilio Video Room.

In a future version of Twilio Live, you will be able to create your own Media Extension, which will allow you to customize the layout and content that your streaming audience sees.
