react-native-video

A <Video> component for react-native, as seen in 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 for changes.

TOC

Installation

Using npm:

npm install --save react-native-video

or using yarn:

yarn add 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

#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 doesnt work properly with the tvOS target so we need to add the library manually.

First select your project in Xcode.

After that, select the tvOS target of your application and select « General » tab

Scroll to « Linked Frameworks and Libraries » and tap on the + button

Select RCTVideo-tvOS

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

The newer ExoPlayer library will work for most people.

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:

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')
}

MainApplication.java

On top, where imports are:

import com.brentvatne.react.ReactVideoPackage;

Add the ReactVideoPackage class to your list of exported packages.

@Override
protected List<ReactPackage> getPackages() {
    return Arrays.asList(
            new MainReactPackage(),
            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
  • UWP: Select node_modules\react-native-video\windows\ReactNativeVideo\ReactNativeVideo.csproj
  • WPF: Select node_modules\react-native-video\windows\ReactNativeVideo.Net46\ReactNativeVideo.Net46.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...
  • UWP: Check ReactNativeVideo from Solution Projects.
  • WPF: Check ReactNativeVideo.Net46 from Solution Projects.

MainPage.cs

Add the ReactVideoPackage class to your list of exported packages.

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

// Load the module

import Video from 'react-native-video';

// 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
       onBuffer={this.onBuffer}                // Callback when remote video is buffering
       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,
  },
});

Platforms: Android ExoPlayer, Android MediaPlayer, iOS, Windows UWP

selectedAudioTrack

Configure which audio track, if any, is played.

selectedAudioTrack={{
  type: Type,
  value: Value
}}

Example:

selectedAudioTrack={{
  type: "title",
  value: "Dubbing"
}}
Type Value Description
"system" (default) N/A Play the audio track that matches the system language. If none match, play the first track.
"disabled" N/A Turn off audio
"title" string Play the audio track with the title specified as the Value, e.g. "French"
"language" string Play the audio track with the language specified as the Value, e.g. "fr"
"index" number Play the audio track with the index specified as the value, e.g. 0

If a track matching the specified Type (and Value if appropriate) is unavailable, the first audio track will be played. If multiple tracks match the criteria, the first match will be used.

Platforms: Android ExoPlayer, iOS

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.

  • -1.0 - Full left
  • 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 representing the language
type Mime type of the track
* TextTrackType.SRT - SubRip (.srt)
* TextTrackType.TTML - TTML (.ttml)
* TextTrackType.VTT - WebVTT (.vtt)
iOS only supports VTT, Android ExoPlayer supports all 3
uri URL for the text track. Currently, only tracks hosted on a webserver are supported

On iOS, sidecar text tracks are only supported for individual files, not HLS playlists. For HLS, you should include the text tracks as part of the playlist.

Example:

import { TextTrackType }, Video from 'react-native-video';

textTracks={[
  {
    title: "English CC",
    language: "en",
    type: TextTrackType.VTT, // "text/vtt"
    uri: "https://bitdash-a.akamaihd.net/content/sintel/subtitles/subtitles_en.vtt"
  },
  {
    title: "Spanish Subtitles",
    language: "es",
    type: TextTrackType.SRT, // "application/x-subrip"
    uri: "https://durian.blender.org/wp-content/content/subtitles/sintel_es.srt"
  }
]}

Platforms: Android ExoPlayer, iOS

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

loadControl

Adjust the load control parameters: minBufferMs, maxBufferMs, bufferForPlaybackMs and playbackAfterRebufferMs.

Property Description
minBufferMs The default minimum duration of media that the player will attempt to ensure is buffered at all times, in milliseconds.
maxBufferMs The default maximum duration of media that the player will attempt to buffer, in milliseconds.
bufferForPlaybackMs The default duration of media that must be buffered for playback to start or resume following a user action such as a seek, in milliseconds.
playbackAfterRebufferMs The default duration of media that must be buffered for playback to resume after a rebuffer, in milliseconds. A rebuffer is defined to be caused by buffer depletion rather than a user action.
loadControl={{
  minBufferMs: number,
  maxBufferMs: number,
  bufferForPlaybackMs: number,
  bufferForPlaybackAfterRebufferMs: number,
}}

Example with default values:

loadControl={{
  minBufferMs: 15000,
  maxBufferMs: 50000,
  bufferForPlaybackMs: 2500,
  bufferForPlaybackAfterRebufferMs: 5000,
}}

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) />
);

dismissFullscreenPlayer

dismissFullscreenPlayer()

Take the player out of fullscreen mode.

Example:

this.player.dismissFullscreenPlayer();

Platforms: Android ExoPlayer, Android MediaPlayer, iOS

FullscreenPlayer

presentFullscreenPlayer()

Put the player in fullscreen mode.

On iOS, this displays the video in a fullscreen view controller with controls.

On Android ExoPlayer & MediaPlayer, this puts the navigation controls in fullscreen mode. It is not a complete fullscreen implementation, so you will still need to apply a style that makes the width and height match your screen dimensions to get a fullscreen video.

Example:

this.player.presentFullscreenPlayer();

Platforms: Android ExoPlayer, Android MediaPlayer, iOS

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 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:

For more detailed info check this article

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:

zip -r -n .mp4 *.mp4 player.video.example.com
// 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 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 to SDK 27 in preparation for Google's requirement that new Android apps use SDK 26 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)
  • Callback to get buffering progress for remote videos
  • Bring API closer to HTML5 <Video> reference
