## 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.

## Installation
|
||
|
||
Using npm:
|
||
|
||
```shell
|
||
npm install --save react-native-video
|
||
```
|
||
|
||
or using yarn:
|
||
|
||
```shell
|
||
yarn add react-native-video
|
||
```
|
||
|
||
<details>
|
||
<summary>iOS</summary>
|
||
|
||
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.
|
||
</details>
|
||
|
||
<details>
|
||
<summary>tvOS</summary>
|
||
|
||
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%">

<summary>Android</summary>
|
||
|
||
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**
|
||
|
||
The newer ExoPlayer library will work for most people.
|
||
|
||
```gradle
|
||
include ':react-native-video'
|
||
project(':react-native-video').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-video/android-exoplayer')
|
||
```
|
||
|
||
If you need to use the old Android MediaPlayer based player, use the following instead:
|
||
|
||
```gradle
|
||
include ':react-native-video'
|
||
project(':react-native-video').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-video/android')
|
||
```
|
||
|
||
|
||
**android/app/build.gradle**
|
||
|
||
```gradle
|
||
dependencies {
|
||
...
|
||
compile project(':react-native-video')
|
||
}
|
||
```
|
||
|
||
**MainApplication.java**
|
||
|
||
On top, where imports are:
|
||
|
||
```java
|
||
import com.brentvatne.react.ReactVideoPackage;
|
||
```
|
||
|
||
Add the `ReactVideoPackage` class to your list of exported packages.
|
||
|
||
```java
|
||
@Override
|
||
protected List<ReactPackage> getPackages() {
|
||
return Arrays.asList(
|
||
new MainReactPackage(),
|
||
new ReactVideoPackage()
|
||
);
|
||
}
|
||
```
|

|
||
|
||
#### selectedTextTrack
|
||
Configure which text track (caption or subtitle), if any, is shown.
|
||
|
||
```
|
||
selectedTextTrack={{
|
||
type: Type,
|
||
value: Value
|
||
}}
|
||
```
|
||
|
||
Example:
|
||
```
|
||
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 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.
|
||
|
||
Platforms: Android ExoPlayer, iOS
|
||
|
||
#### stereoPan
|
||
Adjust the balance of the left and right audio channels. Any value between –1.0 and 1.0 is accepted.
|
||
* **-1.0** - Full left
|
||
* **0.0 (default)** - Center
|
||
* **1.0** - Full right
|
||
|
||
Platforms: Android MediaPlayer
|
||
|
||
#### useTextureView
|
||
Output to a TextureView instead of the default SurfaceView. In general, you will want to use SurfaceView because it is more efficient and provides better performance. However, SurfaceViews 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.
|
||
|
||
* **false (default)** - Use a SurfaceView
|
||
* **true** - Use a TextureView
|
||
|
||
Platforms: Android ExoPlayer
|
||
|
||
#### volume
|
||
Adjust the volume.
|
||
* **1.0 (default)** - Play at full volume
|
||
* **0.0** - Mute the audio
|
||
* **Other values** - Reduce volume
|
||
|
||
Platforms: all
|
||
|
||
### Additional props
|
||
|
||
To see the 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.
|
||
|
||
- By default, iOS 9+ will only load encrypted HTTPS urls. If you need to load content from a webserver that only supports HTTP, you will need to modify your Info.plist file and add the following entry:
|
||
|
||
<img src="./docs/AppTransportSecuritySetting.png" width="50%">
|
||
|
||
For more detailed info check this [article](https://cocoacasts.com/how-to-add-app-transport-security-exception-domains)
|
||
</details>
|
||
|
||
### Android Expansion File Usage
|
||
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}}
|
||
/>
|
||
```
|
||
This will look for an .mp4 file (background.mp4) in the given expansion version.
|
||
|
||
### 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
|
||
source={require('../assets/video/turntable.mp4')}
|
||
/>
|
||
```
|
||
|
||
### 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) )
|
||
|
||
## 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)
