```
Note: You need enable IMA SDK in gradle or pod file - [enable client side ads insertion](/installation)
### `allowsExternalPlayback`
Indicates whether the player allows switching to external playback mode such as AirPlay or HDMI.
- **true (default)** - allow switching to external playback mode
- **false** - Don't allow switching to external playback mode
### `audioOutput`

### `automaticallyWaitsToMinimizeStalling`
A Boolean value that indicates whether the player should automatically delay playback in order to minimize stalling. For clients linked against iOS 10.0 and later
- **false** - Immediately starts playback
- **true (default)** - Delays playback in order to minimize stalling
### `bufferConfig`
Adjust the buffer settings. This prop takes an object with one or more of the properties listed below.
| Property | Type | Description |
| --------------------------------- | ------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| minBufferMs | number | The default minimum duration of media that the player will attempt to ensure is buffered at all times, in milliseconds. |
| maxBufferMs | number | The default maximum duration of media that the player will attempt to buffer, in milliseconds. |
| bufferForPlaybackMs | number | The default duration of media that must be buffered for playback to start or resume following a user action such as a seek, in milliseconds. |
| bufferForPlaybackAfterRebufferMs | number | The default duration of media that must be buffered for playback to resume after a rebuffer, in milliseconds. A rebuffer is defined to be caused by buffer depletion rather than a user action. |
| backBufferDurationMs | number | The number of milliseconds of buffer to keep before the current position. This allows rewinding without rebuffering within that duration. |
| maxHeapAllocationPercent | number | The percentage of available heap that the video can use to buffer, between 0 and 1 |
| minBackBufferMemoryReservePercent | number | The percentage of available app memory at which during startup the back buffer will be disabled, between 0 and 1 |
| minBufferMemoryReservePercent | number | The percentage of available app memory to keep in reserve that prevents buffer from using it, between 0 and 1 |
| cacheSizeMB | number | Cache size in MB, enabling this to prevent new src requests and save bandwidth while repeating videos, or 0 to disable. Android only. |
| live | object | Object containing another config set for live playback configuration, see next table |
Description of live object:
| Property | Type | Description |
| --------------------------------- | ------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| maxPlaybackSpeed | number | The maximum playback speed the player can use to catch up when trying to reach the target live offset. |
| minPlaybackSpeed | number | The minimum playback speed the player can use to fall back when trying to reach the target live offset. |
| maxOffsetMs | number | The maximum allowed live offset. Even when adjusting the offset to current network conditions, the player will not attempt to get above this offset during playback. |
| minOffsetMs | number | The minimum allowed live offset. Even when adjusting the offset to current network conditions, the player will not attempt to get below this offset during playback. |
| targetOffsetMs | number | The target live offset. The player will attempt to get close to this live offset during playback if possible. |
For android, more informations about live configuration can be find [here](https://developer.android.com/media/media3/exoplayer/live-streaming?hl=en)
Example with default values:
```javascript
bufferConfig={{

backBufferDurationMs: 120000,
cacheSizeMB: 0,
live: {
targetOffsetMs: 500,
},
}}
```
Please note that the Android cache is a global cache that is shared among all components; individual components can still opt out of caching behavior by setting cacheSizeMB to 0, but multiple components with a positive cacheSizeMB will be sharing the same one, and the cache size will always be the first value set; it will not change during the app's lifecycle.
### `bufferingStrategy`

### `renderLoader`
Allows you to create custom components to display while the video is loading.
If `renderLoader` is provided, `poster` and `posterResizeMode` will be ignored.
renderLoader is either a component or a function returning a component.
It is recommended to use the function for optimization matter.
`renderLoader` function be called with parameters of type `ReactVideoRenderLoaderProps` to be able to adapt loader
```typescript
interface ReactVideoRenderLoaderProps {
source?: ReactVideoSource; /// source of the video
style?: StyleProp; /// style to apply
resizeMode?: EnumValues; /// resizeMode provided to the video component
}
````
Sample:
```javascript
````
### `repeat`
Determine whether to repeat the video when the end is reached
- **false (default)** - Don't repeat the video
- **true** - Repeat the video
### `reportBandwidth`
Determine whether to generate onBandwidthUpdate events. This is needed due to the high frequency of these events on ExoPlayer.

### `selectedAudioTrack`
Configure which audio track, if any, is played.
```javascript
selectedAudioTrack={{
type: Type,
value: Value
}}
```
Example:
```javascript
selectedAudioTrack={{
type: "title",
value: "Dubbing"
}}
```
| Type | Value | Description |
| ------------------ | ------ | ------------------------------------------------------------------------------------------- |
| "system" (default) | N/A | Play the audio track that matches the system language. If none match, play the first track. |
| "disabled" | N/A | Turn off audio |
| "title" | string | Play the audio track with the title specified as the Value, e.g. "French" |
| "language" | string | Play the audio track with the language specified as the Value, e.g. "fr" |
| "index" | number | Play the audio track with the index specified as the value, e.g. 0 |
If a track matching the specified Type (and Value if appropriate) is unavailable, the first audio track will be played. If multiple tracks match the criteria, the first match will be used.
### `selectedTextTrack`
Configure which text track (caption or subtitle), if any, is shown.
```javascript
selectedTextTrack={{
type: Type,
value: Value
}}
```
Example:
```javascript
selectedTextTrack={{
type: "title",
value: "English Subtitles"
}}
```
| Type | Value | Description |
| ------------------ | ------ | ----------------------------------------------------------------------------- |
| "system" (default) | N/A | Display captions only if the system preference for captions is enabled |
| "disabled" | N/A | Don't display a text track |
| "title" | string | Display the text track with the title specified as the Value, e.g. "French 1" |
| "language" | string | Display the text track with the language specified as the Value, e.g. "fr" |
| "index" | number | Display the text track with the index specified as the value, e.g. 0 |
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.
### `selectedVideoTrack`
Configure which video track should be played. By default, the player uses Adaptive Bitrate Streaming to automatically select the stream it thinks will perform best based on available bandwidth.
```javascript
selectedVideoTrack={{
type: Type,
value: Value
}}
```
Example:
```javascript
selectedVideoTrack={{
type: "resolution",
value: 480
}}
```
| Type | Value | Description |
| ---------------- | ------ | ---------------------------------------------------------------------------- |
| "auto" (default) | N/A | Let the player determine which track to play using ABR |
| "disabled" | N/A | Turn off video |
| "resolution" | number | Play the video track with the height specified, e.g. 480 for the 480p stream |
| "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`
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:
Pass directly the asset to play (deprecated)
```javascript
const sintel = require('./sintel.mp4');
source = {sintel};
```
Or by using an uri (starting from 6.0.0-beta.6)
```javascript
const sintel = require('./sintel.mp4');
source={{ uri: 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://)
Example:
```javascript
source={{uri: 'https://www.sample-videos.com/video/mp4/720/big_buck_bunny_720p_10mb.mp4' }}
```
##### File path (file://)
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.
##### File from asset folder (asset://)
Allows to play a video file from the asset folder from the application
Example:
```javascript
source={{ uri: 'asset:///sintel.mp4' }}
```
##### iPod Library (ipod-library://)
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://`
#### Using DRM content
To setup DRM please follow [this guide](/component/drm)
Example:
```javascript
{
description: 'WV: Secure SD & HD (cbcs,MP4,H264)',
uri: 'https://storage.googleapis.com/wvmedia/cbcs/h264/tears/tears_aes_cbcs.mpd',
drm: {
type: DRMType.WIDEVINE,
licenseServer:
'https://proxy.uat.widevine.com/proxy?provider=widevine_test',
},
},
```
#### Start playback at a specific point in time
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)
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
Provide an optional `title`, `subtitle`, `artist`, `imageUri` and/or `description` properties for the video.
Useful when using notification controls on Android or iOS or to adapt the tvOS playback experience.
Example:
```javascript
source={{
uri: 'https://bitdash-a.akamaihd.net/content/sintel/hls/playlist.m3u8',
metadata: {
title: 'Custom Title',
subtitle: 'Custom Subtitle',
artist: 'Custom Artist',
description: 'Custom Description',
imageUri: 'https://pbs.twimg.com/profile_images/1498641868397191170/6qW2XkuI_400x400.png'
}
}}
```
#### `contentStartTime`
The start time in ms for SSAI content. This determines at what time to load the video info like resolutions. Use this only when you have SSAI stream where ads resolution is not the same as content resolution.
Note: This feature only works on DASH streams
#### `textTracksAllowChunklessPreparation`
AllowChunklessPreparation for hls media source.
see: [disabling-chunkless](https://developer.android.com/media/media3/exoplayer/hls?#disabling-chunkless) in android documentation.
Default value: true.
```javascript
source={{
uri: 'https://bitdash-a.akamaihd.net/content/sintel/hls/playlist.m3u8',
textTracksAllowChunklessPreparation: false,
}}
```
#### `textTracks`
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"
},
{

### `subtitleStyle`
| Property | Platform | Description | Platforms |
| ------------- | -------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------ |
| fontSize | Android | Adjust the font size of the subtitles. Default: font size of the device | Android |
| paddingTop | Android | Adjust the top padding of the subtitles. Default: 0 | Android |
| paddingBottom | Android | Adjust the bottom padding of the subtitles. Default: 0 | Android |
| paddingLeft | Android | Adjust the left padding of the subtitles. Default: 0 | Android |
| paddingRight | Android | Adjust the right padding of the subtitles. Default: 0 | Android |
| opacity | Android, iOS | Adjust the visibility of subtitles with 0 hiding and 1 fully showing them. Android supports float values between 0 and 1 for varying opacity levels, whereas iOS supports only 0 or 1. Default: 1. | Android, iOS |
| subtitlesFollowVideo | Android | Boolean to adjust position of subtitles. Default: true |
Example:
```javascript
subtitleStyle={{ paddingBottom: 50, fontSize: 20, opacity: 0 }}
```
Note for `subtitlesFollowVideo`
`subtitlesFollowVideo` helps to determine how the subtitles are positionned.
To understand this prop you need to understand how views management works.
The main View style passed to react native video is the position reserved to display the video component.
It may not match exactly the real video size.
For exemple, you can pass a 4:3 video view and render a 16:9 video inside.
So there is a second view, the video view.
Subtitles are managed in a third view.
First react-native-video resize the video to keep aspect ratio (depending on `resizeMode` property) and put it in main view.
* When putting subtitlesFollowVideo to true, the subtitle view will be adapt to the video view.
It means that if the video is displayed out of screen, the subtitles may also be displayed out of screen.
* When putting subtitlesFollowVideo to false, the subtitle view will keep adapting to the main view.
It means that if the video is displayed out of screen, the subtitles may also be displayed out of screen.
This prop can be changed on runtime.
### `textTracks`
> [!WARNING]
> deprecated, use source.textTracks instead. changing text tracks will restart playback
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"
}
]}
```
### `showNotificationControls`
Controls whether to show media controls in the notification area.
For Android each Video component will have its own notification controls and for iOS only one notification control will be shown for the last Active Video component.
On android this will also allow for external controls, Google Assistant session and other benefits of MediaSession.
You propably want also set `playInBackground` to `true` to keep the video playing when the app is in the background or `playWhenInactive` to `true` to keep the video playing when notifications or the Control Center are in front of the video.
To customize the notification controls you can use `metadata` property in the `source` prop.
- **false (default)** - Don't show media controls in the notification area
- **true** - Show media controls in the notification area
**To test notification controls on iOS you need to run the app on a real device, as the simulator does not support it.**
**For Android you have to add the following code in your `AndroidManifest.xml` file:**
```xml
...
...
...
```
### `useSecureView`
> [!WARNING]
> deprecated, use viewType instead
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
### `useTextureView`
> [!WARNING]
> deprecated, use viewType instead
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
### `viewType`
Allow to explicitly specify view type.
This flag replace `useSecureView` and `useTextureView` fields.
There are 3 available values:
- 'textureView': The video is rendered in a texture view. it allows mapping the view on a texture (useful for 3D).
DRM playback is not supported on textureView, if drm prop is provided, the suface will be transformed to a SurfaceView.
- 'surfaceView' (default): The video is rendered in a surface. take less resources to be rendered.
- 'secureView': The video is rendered in a surface which disallow taking screenshot of the video
### `volume`
Adjust the volume.
- **1.0 (default)** - Play at full volume
- **0.0** - Mute the audio
- **Other values** - Reduce volume
### `cmcd`
Configure CMCD (Common Media Client Data) parameters. CMCD is a standard for conveying client-side metrics and capabilities to servers, which can help improve streaming quality and performance.
For detailed information about CMCD, please refer to the [CTA-5004 Final Specification](https://cdn.cta.tech/cta/media/media/resources/standards/pdfs/cta-5004-final.pdf).
- **false (default)** - Don't use CMCD
- **true** - Use default CMCD configuration
- **object** - Use custom CMCD configuration
When providing an object, you can configure the following properties:
| Property | Type | Description |
|----------|-------------------------|----------------------------------------------------|
| `mode` | `CmcdMode` | The mode for sending CMCD data |
| `request` | `CmcdData` | Custom key-value pairs for the request object |
| `session` | `CmcdData` | Custom key-value pairs for the session object |
| `object` | `CmcdData` | Custom key-value pairs for the object metadata |
| `status` | `CmcdData` | Custom key-value pairs for the status information |
Note: The `mode` property defaults to `CmcdMode.MODE_QUERY_PARAMETER` if not specified.
#### `CmcdMode`
CmcdMode is an enum that defines how CMCD data should be sent:
- `CmcdMode.MODE_REQUEST_HEADER` (0) - Send CMCD data in the HTTP request headers.
- `CmcdMode.MODE_QUERY_PARAMETER` (1) - Send CMCD data as query parameters in the URL.
#### `CmcdData`
CmcdData is a type representing custom key-value pairs for CMCD data. It's defined as:
```typescript
type CmcdData = Record<`${string}-${string}`, string | number>;
```
Custom key names MUST include a hyphenated prefix to prevent namespace collisions. It's recommended to use a reverse-DNS syntax for custom prefixes.
Example:
```javascript
```
