|
||
|
||
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.
|
||
|
||
### Version 3.0 breaking changes
|
||
Version 3.0 features a number of changes to existing behavior. See [Updating](#updating) for changes.

|
||
## 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` doesn’t work 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%">
|
||
</details>
|
||
|
||
<details>
|
||
<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()
|
||
);
|
||
}
|
||
```
|
||
</details>
|
||
|
||
<details>
|
||
<summary>Windows</summary>
|
||
|
||
Make the following additions to the given files manually:
|
||
|
||
**windows/myapp.sln**
|
||
|
||
Add the `ReactNativeVideo` project to your solution.
|
||
|
||

||
|
||
Add a reference to `ReactNativeVideo` to your main application project. From Visual Studio 2015:
|
||
|
||
1. Right-click main application project > Add > Reference...
|
||
* UWP: 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

#### 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 (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.
|
||
|
||
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.

* **0.0 (default)** - Center
|
||
* **1.0** - Full right
|
||
|
||
Platforms: Android MediaPlayer
|
||
|
||
#### textTracks
|
||
Load one or more "sidecar" text tracks. This takes an array of objects representing each track. Each object should have the format:
|
||
|
||
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<br> * TextTrackType.SRT - .srt SubRip Subtitle<br> * TextTrackType.TTML - .ttml TTML<br> * TextTrackType.VTT - .vtt WebVTT
|
||
uri | URL for the text track. Currently, only tracks hosted on a webserver are supported
|
||
|
||
Example:
|
||
```
|
||
import { TextTrackType }, Video from 'react-native-video';
|
||
|
||
textTracks={[
|
||
{
|
||
title: "English CC",
|
||
language: "en",
|
||
type: "text/vtt", TextTrackType.VTT,
|
||
uri: "https://bitdash-a.akamaihd.net/content/sintel/subtitles/subtitles_en.vtt"
|
||
},
|
||
{
|
||
title: "Spanish Subtitles",
|
||
language: "es",
|
||
type: "application/x-subrip", TextTrackType.SRT,
|
||
uri: "https://durian.blender.org/wp-content/content/subtitles/sintel_es.srt"
|
||
}
|
||
]}
|
||
```
|
||
|
||
This isn't support on iOS because AVPlayer doesn't support it. Text tracks must be loaded as part of an HLS playlist.
|
||
|
||
Platforms: Android ExoPlayer
|
||
|
||
#### 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
|
||

{ value: 'Internet Stream', identifier: 'TRSO' },
|
||
{ value: 'Any Time You Like', identifier: 'TIT2' }
|
||
]
|
||
}
|
||
```
|
||
|
||
Platforms: Android ExoPlayer, iOS
|
||
|
||
### Methods
|
||
Methods operate on a ref to the Video element. You can create a ref using code like:
|
||
```
|
||
return (
|
||
<Video source={...}
|
||
ref => (this.player = ref) />
|
||
);
|
||
```
|
||
|
||
#### seek()
|
||
`seek(seconds)`
|
||
|
||
Seek to the specified position represented by seconds. seconds is a float value.
|
||
|
||
`seek()` can only be called after the `onLoad` event has fired.
|
||
|
||
Example:
|
||
```
|
||
this.player.seek(200); // Seek to 3 minutes, 20 seconds
|
||
```
|
||
|
||
Platforms: all
|
||
|
||
##### Exact seek
|
||
|
||
By default iOS seeks within 100 milliseconds of the target position. If you need more accuracy, you can use the seek with tolerance method:
|
||
|
||
`seek(seconds, tolerance)`
|
||
|
||
tolerance is the max distance in milliseconds from the seconds position that's allowed. Using a more exact tolerance can cause seeks to take longer. If you want to seek exactly, set tolerance to 0.
|
||
|
||
Example:
|
||
```
|
||
this.player.seek(120, 50); // Seek to 2 minutes with +/- 50 milliseconds accuracy
|
||
```
|
||
|
||
Platforms: iOS
|
||
|
||
|
||
### 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%">
|
||
|
||

|
||
|
||
### Android Expansion File Usage
|
||
Expansions files allow you to ship assets that exceed the 100MB apk size limit and don't need to be updated each time you push an app update.
|
||
|
||
This only supports mp4 files and they must not be compressed. Example command line for preventing compression:
|
||
```bash
|
||
zip -r -n .mp4 *.mp4 player.video.example.com
|
||
```
|
||
|
||
```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.
|
||
resizeMode="cover" // Fill the whole screen at aspect ratio.
|
||
style={styles.backgroundVideo} />
|
||
|
||
### 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.
|
||
|
||
## Updating
|
||
|
||
### Version 3.0
|
||
|
||
#### All platforms now auto-play
|
||
Previously, on Android ExoPlayer if the paused prop was not set, the media would not automatically start playing. The only way it would work was if you set `paused={false}`. This has been changed to automatically play if paused is not set so that the behavior is consistent across platforms.
|
||
|
||
#### All platforms now keep their paused state when returning from the background
|
||
Previously, on Android MediaPlayer if you setup an AppState event when the app went into the background and set a paused prop so that when you returned to the app the video would be paused it would be ignored.
|
||
|
||
Note, Windows does not have a concept of an app going into the background, so this doesn't apply there.
|
||
|
||
#### Use Android SDK 27 by default
|
||
Version 3.0 updates the Android build tools and SDK to version 27. React Native is in the process of [switchting over](https://github.com/facebook/react-native/issues/18095#issuecomment-395596130) to SDK 27 in preparation for Google's requirement that new Android apps [use SDK 26](https://android-developers.googleblog.com/2017/12/improving-app-security-and-performance.html) by August 2018.
|
||
|
||
You will either need to install the version 27 SDK and version 27.0.3 buildtools or modify your build.gradle file to configure react-native-video to use the same build settings as the rest of your app as described below.
|
||
|
||
##### Using app build settings
|
||
You will need to create a `project.ext` section in the top-level build.gradle file (not app/build.gradle). Fill in the values from the example below using the values found in your app/build.gradle file.
|
||
```
|
||
// Top-level build file where you can add configuration options common to all sub-projects/modules.
|
||
|
||
buildscript {
|
||
... // Various other settings go here
|
||
}
|
||
|
||
allprojects {
|
||
... // Various other settings go here
|
||
|
||
project.ext {
|
||
compileSdkVersion = 23
|
||
buildToolsVersion = "23.0.1"
|
||
|
||
minSdkVersion = 16
|
||
targetSdkVersion = 22
|
||
}
|
||
}
|
||
```
|
||
|
||
If you encounter an error `Could not find com.android.support:support-annotations:27.0.0.` reinstall your Android Support Repository.
|
||
|
||
## TODOS
|
||
|
||
- [ ] 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)
