## 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

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
  ...
}
```

#### 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**

```
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())
```

#### Windows

Make the following additions to the given files manually:

**windows/myapp.sln**

Add the `ReactNativeVideo` project to your solution.

1. Open the solution in Visual Studio 2015
2. Right-click Solution icon in Solution Explorer > Add > Existing Project...
3. Select `node_modules\react-native-video\windows\ReactNativeVideo\ReactNativeVideo.csproj`

**windows/myapp/myapp.csproj**

Add a reference to `ReactNativeVideo` to your main application project. From Visual Studio 2015:

1. Right-click main application project > Add > Reference...
2. Check `ReactNativeVideo` from Solution Projects.

**MainPage.cs**

Add the `ReactVideoPackage` class to your list of exported packages.
```cs
using ReactNative;
using ReactNative.Modules.Core;
using ReactNative.Shell;
using ReactNativeVideo; // <-- Add this
using System.Collections.Generic;
...

        public override List<IReactPackage> Packages
        {
            get
            {
                return new List<IReactPackage>
                {
                    new MainReactPackage(),
                    new ReactVideoPackage(), // <-- Add this
                };
            }
        }

...
```

## 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.
       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.
       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
       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,
  },
});
```


## 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.
       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: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)
- [x] Callback to get buffering progress for remote videos
- [ ] Bring API closer to HTML5 `<Video>` [reference](http://devdocs.io/html/element/video)
