Both iOS & Android offer Settings to enable Captions for hearing impaired people. If "system" is selected and the Captions Setting is enabled, iOS/Android will look for a caption that matches that customer's language and display it.

Both iOS & Android (only 4.4 and higher) offer Settings to enable Captions for hearing impaired people. If "system" is selected and the Captions Setting is enabled, iOS/Android will look for a caption that matches that customer's language and display it. 

If a track matching the specified Type (and Value if appropriate) is unavailable, no text track will be displayed. If multiple tracks match the criteria, the first match will be used.

Platforms: Android MediaPlayer

#### textTracks

Load one or more "sidecar" text tracks. This takes an array of objects representing each track. Each object should have the format:

Property | Description

--- | ---

title | Descriptive name for the track

language | 2 character [ISO 639-1 code](https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes) representing the language

type | Mime type of the track<br> * TextTrackType.SRT - .srt SubRip Subtitle<br> * TextTrackType.TTML - .ttml TTML<br> * TextTrackType.VTT - .vtt WebVTT

uri | URL for the text track. Currently, only tracks hosted on a webserver are supported

Example:

```

import { TextTrackType }, Video from 'react-native-video';

textTracks={[

  {

    title: "English CC",

    language: "en",

    type: "text/vtt", TextTrackType.VTT,

    uri: "https://bitdash-a.akamaihd.net/content/sintel/subtitles/subtitles_en.vtt"

  },

  {

    title: "Spanish Subtitles",

    language: "es",

    type: "application/x-subrip", TextTrackType.SRT,

    uri: "https://durian.blender.org/wp-content/content/subtitles/sintel_es.srt"

  }

]}

```

This isn't support on iOS because AVPlayer doesn't support it. Text tracks must be loaded as part of an HLS playlist.

Platforms: Android ExoPlayer

#### useTextureView

Output to a TextureView instead of the default SurfaceView. In general, you will want to use SurfaceView because it is more efficient and provides better performance. However, SurfaceViews has two limitations:

* It can't be animated, transformed or scaled
