## 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 >= 0.19.0
|
|
|
|
### Add it to your project
|
|
|
|
Run `npm i -S react-native-video`
|
|
|
|
#### iOS
|
|
|
|
Install [rnpm](https://github.com/rnpm/rnpm) and run `rnpm link react-native-video`.
|
|
|
|
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
|
|
...
|
|
}
|
|
```
|
|
|
|
#### Android
|
|
|
|
Install [rnpm](https://github.com/rnpm/rnpm) and run `rnpm link react-native-video`
|
|
|
|
Or if you have trouble using [rnpm](https://github.com/rnpm/rnpm), make the following additions to the given files manually:
|
|
|
|
**android/settings.gradle**
|
|
|
|
```
|
|
include ':react-native-video'
|
|
project(':react-native-video').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-video/android')
|
|
```
|
|
|
|
**android/app/build.gradle**
|
|
|
|
```
|
|
dependencies {
|
|
...
|
|
compile project(':react-native-video')
|
|
}
|
|
```
|
|
|
|
**MainActivity.java**
|
|
|
|
On top, where imports are:
|
|
|
|
```java
|
|
import com.brentvatne.react.ReactVideoPackage;
|
|
```
|
|
|
|
Under `.addPackage(new MainReactPackage())`:
|
|
|
|
```java
|
|
.addPackage(new ReactVideoPackage())
|
|
```
|
|
|
|
### Note: In react-native >= 0.29.0 you have to edit `MainApplication.java`
|
|
|
|
**MainApplication.java** (react-native >= 0.29.0)
|
|
|
|
On top, where imports are:
|
|
|
|
```java
|
|
import com.brentvatne.react.ReactVideoPackage;
|
|
```
|
|
|
|
Under `.addPackage(new MainReactPackage())`:
|
|
|
|
```java
|
|
.addPackage(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.
|
|
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 aentering background.
|
|
playWhenInactive={false} // [iOS] Video continues to play whcontrol or notification center are shown.
|
|
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 `0.32` iOS should also be 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.
|
|
|
|
## Static Methods
|
|
|
|
`seek(seconds)`
|
|
|
|
Seeks the video to the specified time (in seconds). 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:brentvatne/react-native-video.git
|
|
cd react-native-video/Examples/VideoPlayer
|
|
npm install
|
|
open 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)
|
|
- [ ] Callback to get buffering progress for remote videos
|
|
- [ ] Bring API closer to HTML5 `<Video>` [reference](http://devdocs.io/html/element/video)
