| "index"          | number | Play the video track with the index specified as the value, e.g. 0           |

If a track matching the specified Type (and Value if appropriate) is unavailable, ABR will be used.

### `shutterColor`

<PlatformsList types={['Android']} />

Apply color to shutter view, if you see black flashes before video start then set

```javascript
shutterColor = 'transparent';
```

- black (default)

### `source`

Sets the media source. You can pass an asset loaded via require or an object with a uri.

Setting the source will trigger the player to attempt to load the provided media with all other given props. Please be sure that all props are provided before/at the same time as setting the source.

Rendering the player component with a null source will init the player, and start playing once a source value is provided.

Providing a null source value after loading a previous source will stop playback, and clear out the previous source content.

The docs for this prop are incomplete and will be updated as each option is investigated and tested.

#### Asset loaded via require

> ⚠️ on iOS, you file name must not contain spaces eg. `my video.mp4` will not work, use `my-video.mp4` instead

Example:

```javascript
const sintel = require('./sintel.mp4');

source = {sintel};
```

#### URI string

A number of URI schemes are supported by passing an object with a `uri` attribute.

All uri string shall be url encoded.
For exemple 'www.myurl.com/blabla?q=test uri' is invalid, where 'www.myurl.com/blabla?q=test%20uri' is valid

##### Web address (http://, https://)

<PlatformsList types={['All']} />

Example:

```javascript
source={{uri: 'https://www.sample-videos.com/video/mp4/720/big_buck_bunny_720p_10mb.mp4' }}
```

##### File path (file://)

<PlatformsList types={['Android']} />

Example:

```javascript
source={{ uri: 'file:///sdcard/Movies/sintel.mp4' }}
```

Note: Your app will need to request permission to read external storage if you're accessing a file outside your app.

##### iPod Library (ipod-library://)

<PlatformsList types={['iOS']} />

Path to a sound file in your iTunes library. Typically shared from iTunes to your app.

Example:

```javascript
source={{ uri: 'ipod-library:///path/to/music.mp3' }}
```

Note: Using this feature adding an entry for NSAppleMusicUsageDescription to your Info.plist file as described [here](https://developer.apple.com/library/archive/documentation/General/Reference/InfoPlistKeyReference/Articles/CocoaKeys.html)

##### Explicit mimetype for the stream

Provide a member `type` with value (`mpd`/`m3u8`/`ism`) inside the source object.
Sometimes is needed when URL extension does not match with the mimetype that you are expecting, as seen on the next example. (Extension is .ism -smooth streaming- but file served is on format mpd -mpeg dash-)

Example:

```javascript
source={{ uri: 'http://host-serving-a-type-different-than-the-extension.ism/manifest(format=mpd-time-csf)',
type: 'mpd' }}
```

##### Other protocols

The following other types are supported on some platforms, but aren't fully documented yet:
`content://, ms-appx://, ms-appdata://, assets-library://`

#### Start playback at a specific point in time

<PlatformsList types={['Android', 'iOS']} />

Provide an optional `startPosition` for video. Value is in milliseconds. If the `cropStart` prop is applied, it will be applied from that point forward.
(If it is negative or undefined or null, it is ignored)

#### Playing only a portion of the video (start & end time)

<PlatformsList types={['Android', 'iOS']} />

Provide an optional `cropStart` and/or `cropEnd` for the video. Value is in milliseconds. Useful when you want to play only a portion of a large video.

Example

```javascript
source={{ uri: 'https://bitdash-a.akamaihd.net/content/sintel/hls/playlist.m3u8', cropStart: 36012, cropEnd: 48500 }}

source={{ uri: 'https://bitdash-a.akamaihd.net/content/sintel/hls/playlist.m3u8', cropStart: 36012 }}

source={{ uri: 'https://bitdash-a.akamaihd.net/content/sintel/hls/playlist.m3u8', cropEnd: 48500 }}
```

#### Overriding the metadata of a source

<PlatformsList types={['tvOS']} />

Provide an optional `title`, `subtitle`, `customImageUri` and/or `description` properties for the video.
Useful when to adapt the tvOS playback experience.

Example:

```javascript
source={{
    uri: 'https://bitdash-a.akamaihd.net/content/sintel/hls/playlist.m3u8',
    title: 'Custom Title',
    subtitle: 'Custom Subtitle',
    description: 'Custom Description',
    customImageUri: 'https://pbs.twimg.com/profile_images/1498641868397191170/6qW2XkuI_400x400.png'
  }}
```

### `subtitleStyle`

| Property      | Description                                                             | Platforms |
| ------------- | ----------------------------------------------------------------------- | --------- |
| fontSize      | Adjust the font size of the subtitles. Default: font size of the device | Android   |
| paddingTop    | Adjust the top padding of the subtitles. Default: 0                     | Android   |
| paddingBottom | Adjust the bottom padding of the subtitles. Default: 0                  | Android   |
| paddingLeft   | Adjust the left padding of the subtitles. Default: 0                    | Android   |
| paddingRight  | Adjust the right padding of the subtitles. Default: 0                   | Android   |

Example:

```javascript
subtitleStyle={{ paddingBottom: 50, fontSize: 20 }}
```

### `textTracks`

<PlatformsList types={['Android', 'iOS', 'visionOS']} />

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

> ⚠️ This feature does not work with HLS playlists (e.g m3u8) on iOS

| Property | Description                                                                                                                                                                      |
| -------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| title    | Descriptive name for the track                                                                                                                                                   |
| language | 2 letter [ISO 639-1 code](https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes) representing the language                                                                       |
| type     | Mime type of the track _ TextTrackType.SRT - SubRip (.srt) _ TextTrackType.TTML - TTML (.ttml) \* TextTrackType.VTT - WebVTT (.vtt)iOS only supports VTT, Android supports all 3 |
| uri      | URL for the text track. Currently, only tracks hosted on a webserver are supported                                                                                               |

On iOS, sidecar text tracks are only supported for individual files, not HLS playlists. For HLS, you should include the text tracks as part of the playlist.

Note: Due to iOS limitations, sidecar text tracks are not compatible with Airplay. If textTracks are specified, AirPlay support will be automatically disabled.

Example:

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

textTracks={[
  {
    title: "English CC",
    language: "en",
    type: TextTrackType.VTT, // "text/vtt"
    uri: "https://bitdash-a.akamaihd.net/content/sintel/subtitles/subtitles_en.vtt"
  },
  {
    title: "Spanish Subtitles",
    language: "es",
    type: TextTrackType.SRT, // "application/x-subrip"
    uri: "https://durian.blender.org/wp-content/content/subtitles/sintel_es.srt"
  }
]}
```

### `trackId`

<PlatformsList types={['Android']} />

Configure an identifier for the video stream to link the playback context to the events emitted.

### `useTextureView`

<PlatformsList types={['Android']} />

Controls whether to output to a TextureView or SurfaceView.

SurfaceView is more efficient and provides better performance but has two limitations:

- It can't be animated, transformed or scaled
- You can't overlay multiple SurfaceViews

useTextureView can only be set at same time you're setting the source.

- **true (default)** - Use a TextureView
- **false** - Use a SurfaceView

### `useSecureView`

<PlatformsList types={['Android']} />

Force the output to a SurfaceView and enables the secure surface.

This will override useTextureView flag.

SurfaceView is is the only one that can be labeled as secure.

- **true** - Use security
- **false (default)** - Do not use security

### `volume`

<PlatformsList types={['All']} />

Adjust the volume.

- **1.0 (default)** - Play at full volume
- **0.0** - Mute the audio
- **Other values** - Reduce volume

### `localSourceEncryptionKeyScheme`

<PlatformsList types={['iOS']} />

Set the url scheme for stream encryption key for local assets

Type: String

Example:

```
localSourceEncryptionKeyScheme="my-offline-key"
```
