## react-native-video
|
||
|
||
A `<Video>` component for react-native, as seen in
|
||
[react-native-login](https://github.com/brentvatne/react-native-login)!
|
||
|
||
Requires react-native >= 0.40.0, for RN support of 0.19.0 - 0.39.0 please use a pre 1.0 version.
|
||
|
||
### Add it to your project
|
||
|
||
Run `npm i -S react-native-video`
|
||
|
||
#### iOS
|
||
|
||
Run `react-native link` to link the react-native-video library.
|
||
|
||
If you would like to allow other apps to play music over your video component, add:
|
||
|
||
**AppDelegate.m**
|
||
|
||
```objective-c
|
||
#import <AVFoundation/AVFoundation.h> // import
|
||
|
||
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
|
||
{
|
||
...
|
||
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryAmbient error:nil]; // allow
|
||
...
|
||
}
|
||
```
|
||
Note: you can also use the `ignoreSilentSwitch` prop, shown below.
|
||
|
||
#### tvOS
|
||
|
||
Run `react-native link` to link the react-native-video library.
|
||
|
||
`react-native link` don’t works properly with the tvOS target so we need to add the library manually.
|
||
|
||
First select your project in Xcode.
|
||
|
||
<img src="./docs/tvOS-step-1.jpg" width="40%">
|
||
|
||
After that, select the tvOS target of your application and select « General » tab
|
||
|
||
<img src="./docs/tvOS-step-2.jpg" width="40%">
|
||
|
||
Scroll to « Linked Frameworks and Libraries » and tap on the + button
|
||
|
||
<img src="./docs/tvOS-step-3.jpg" width="40%">
|
||
|
||
Select RCTVideo-tvOS
|
||
|
||
<img src="./docs/tvOS-step-4.jpg" width="40%">
|
||
|
||
That’s all, you can use react-native-video for your tvOS application
|
||
|
||
#### Android
|
||
|
||
Run `react-native link` to link the react-native-video library.
|
||
|
||
Or if you have trouble, make the following additions to the given files manually:
|
||
|
||
**android/settings.gradle**
|
||
|
||
```gradle
|

|
||
```
|
||
|
||
**android/app/build.gradle**
|
||
|
||
```gradle
|
||
dependencies {

|
||
protected List<ReactPackage> getPackages() {
|
||
return Arrays.asList(
|
||
new MainReactPackage(),

||
new ReactVideoPackage()
|
||
);
|
||
}
|
||
```
|
||
|
||

...
|
||
```
|
||
|
||
## Usage
|
||
|
||
```javascript
|
||
// Within your render function, assuming you have a file called
|
||
// "background.mp4" in your project. You can include multiple videos
|
||
// on a single screen if you like.
|
||
|
||
<Video source={{uri: "background"}} // Can be a URL or a local file.
|
||
poster="https://baconmockup.com/300/200/" // uri to an image to display until the video plays
|
||
ref={(ref) => {
|
||
this.player = ref
|
||
}} // Store reference
|
||
rate={1.0} // 0 is paused, 1 is normal.
|
||
volume={1.0} // 0 is muted, 1 is normal.
|
||
muted={false} // Mutes the audio entirely.
|
||
paused={false} // Pauses playback entirely.
|
||
resizeMode="cover" // Fill the whole screen at aspect ratio.*
|
||
repeat={true} // Repeat forever.
|
||
playInBackground={false} // Audio continues to play when app entering background.
|
||
playWhenInactive={false} // [iOS] Video continues to play when control or notification center are shown.
|
||
ignoreSilentSwitch={"ignore"} // [iOS] ignore | obey - When 'ignore', audio will still play with the iOS hard silent switch set to silent. When 'obey', audio will toggle with the switch. When not specified, will inherit audio settings as usual.
|
||
progressUpdateInterval={250.0} // [iOS] Interval to fire onProgress (default to ~250ms)
|
||
onLoadStart={this.loadStart} // Callback when video starts to load
|
||
onLoad={this.setDuration} // Callback when video loads
|
||
onProgress={this.setTime} // Callback every ~250ms with currentTime
|
||
onEnd={this.onEnd} // Callback when playback finishes
|
||
onError={this.videoError} // Callback when video cannot be loaded
|
||
onBuffer={this.onBuffer} // Callback when remote video is buffering
|
||
onTimedMetadata={this.onTimedMetadata} // Callback when the stream receive some metadata
|
||
style={styles.backgroundVideo} />
|
||
|
||
// Later to trigger fullscreen
|
||
this.player.presentFullscreenPlayer()
|
||
|
||
// To set video position in seconds (seek)
|
||
this.player.seek(0)
|
||
|
||
// Later on in your styles..
|
||
var styles = StyleSheet.create({
|
||
backgroundVideo: {
|
||
position: 'absolute',
|
||
top: 0,
|
||
left: 0,
|
||
bottom: 0,
|
||
right: 0,
|
||
},
|
||
});
|
||
```
|
||
|
||
- * *For iOS you also need to specify muted for this to work*
|
||
|
||
To see full list of available props, you can check [the propTypes](https://github.com/react-native-community/react-native-video/blob/master/Video.js#L246) of the Video.js component.
|
||
|
||
## Android Expansion File Usage
|
||
|
||
```javascript
|
||
// Within your render function, assuming you have a file called
|
||
// "background.mp4" in your expansion file. Just add your main and (if applicable) patch version
|
||
<Video source={{uri: "background", mainVer: 1, patchVer: 0}} // Looks for .mp4 file (background.mp4) in the given expansion version.
|
||
poster="https://baconmockup.com/300/200/" // uri to an image to display until the video plays
|
||
rate={1.0} // 0 is paused, 1 is normal.
|
||
volume={1.0} // 0 is muted, 1 is normal.
|
||
muted={false} // Mutes the audio entirely.
|
||
paused={false} // Pauses playback entirely.
|
||
resizeMode="cover" // Fill the whole screen at aspect ratio.
|
||
repeat={true} // Repeat forever.
|
||
onLoadStart={this.loadStart} // Callback when video starts to load
|
||
onLoad={this.setDuration} // Callback when video loads
|
||
onProgress={this.setTime} // Callback every ~250ms with currentTime
|
||
onEnd={this.onEnd} // Callback when playback finishes
|
||
onError={this.videoError} // Callback when video cannot be loaded
|
||
style={styles.backgroundVideo} />
|
||
|
||
// Later on in your styles..
|
||
var styles = Stylesheet.create({
|
||
backgroundVideo: {
|
||
position: 'absolute',
|
||
top: 0,
|
||
left: 0,
|
||
bottom: 0,
|
||
right: 0,
|
||
},
|
||
});
|
||
```
|
||
|
||
### Load files with the RN Asset System
|
||
|
||
The asset system [introduced in RN `0.14`](http://www.reactnative.com/react-native-v0-14-0-released/) allows loading image resources shared across iOS and Android without touching native code. As of RN `0.31` [the same is true](https://github.com/facebook/react-native/commit/91ff6868a554c4930fd5fda6ba8044dbd56c8374) of mp4 video assets for Android. As of [RN `0.33`](https://github.com/facebook/react-native/releases/tag/v0.33.0) iOS is also supported. Requires `react-native-video@0.9.0`.
|
||
|
||
```
|
||
<Video
|
||
repeat
|
||
resizeMode='cover'
|
||
source={require('../assets/video/turntable.mp4')}
|
||
style={styles.backgroundVideo}
|
||
/>
|
||
```
|
||
|
||
### Play in background on iOS
|
||
|
||
To enable audio to play in background on iOS the audio session needs to be set to `AVAudioSessionCategoryPlayback`. See [Apple documentation][3] for additional details. (NOTE: there is now a ticket to [expose this as a prop]( https://github.com/react-native-community/react-native-video/issues/310) )
|
||
|
||
## Static Methods
|
||
|
||
`seek(seconds)`
|
||
|
||
Seeks the video to the specified time (in seconds). Access using a ref to the component
|
||
|
||
`presentFullscreenPlayer()`
|
||
|
||
Toggles a fullscreen player. Access using a ref to the component.
|
||
|
||
## Examples
|
||
|
||
- See an [Example integration][1] in `react-native-login` *note that this example uses an older version of this library, before we used `export default` -- if you use `require` you will need to do `require('react-native-video').default` as per instructions above.*
|
||
- Try the included [VideoPlayer example][2] yourself:
|
||
|
||
```sh
|
||
git clone git@github.com:react-native-community/react-native-video.git
|
||
cd react-native-video/example
|
||
npm install
|
||
open ios/VideoPlayer.xcodeproj
|
||
|
||
```
|
||
|
||
Then `Cmd+R` to start the React Packager, build and run the project in the simulator.
|
||
|
||
- [Lumpen Radio](https://github.com/jhabdas/lumpen-radio) contains another example integration using local files and full screen background video.
|
||
|
||
## TODOS
|
||
|
||
- [ ] Add support for captions
|
||
- [ ] Add support for playing multiple videos in a sequence (will interfere with current `repeat` implementation)
|
||
- [x] Callback to get buffering progress for remote videos
|
||
- [ ] Bring API closer to HTML5 `<Video>` [reference](http://devdocs.io/html/element/video)
