Audio description - React Native
On React Native, the React-Native-Video package has support for switching audio tracks. This allows you to offer users a way to switch to an audio description track.
Note: The audio tracks must be encoded in the file, this is not something you add programmatically.
import Video from 'react-native-video';
<Video
selectedAudioTrack={{
type: "audio-description",
value: "en"
}}
/>
