source
Sets the media source. You can pass an asset loaded via require or an object with a uri.
Setting the source will trigger the player to attempt to load the provided media with all other given props. Please be sure that all props are provided before/at the same time as setting the source.
Rendering the player component with a null source will init the player, and start playing once a source value is provided.
Providing a null source value after loading a previous source will stop playback, and clear out the previous source content.
The docs for this prop are incomplete and will be updated as each option is investigated and tested.
Asset loaded via require
Example:
const sintel = require('./sintel.mp4');
source={sintel}
URI string
A number of URI schemes are supported by passing an object with a uri attribute.
Web address (http://, https://)
Example:
source={{uri: 'https://www.sample-videos.com/video/mp4/720/big_buck_bunny_720p_10mb.mp4' }}
Platforms: all
File path (file://)
Example:
source={{ uri: 'file:///sdcard/Movies/sintel.mp4' }}
Note: Your app will need to request permission to read external storage if you're accessing a file outside your app.
Platforms: Android, possibly others
iPod Library (ipod-library://)
Path to a sound file in your iTunes library. Typically shared from iTunes to your app.
Example:
source={{ uri: 'ipod-library:///path/to/music.mp3' }}
Note: Using this feature adding an entry for NSAppleMusicUsageDescription to your Info.plist file as described here
Platforms: iOS
Explicit mimetype for the stream
Provide a member type with value (mpd/m3u8/ism) inside the source object.
Sometimes is needed when URL extension does not match with the mimetype that you are expecting, as seen on the next example. (Extension is .ism -smooth streaming- but file served is on format mpd -mpeg dash-)
Example:
source={{ uri: 'http://host-serving-a-type-different-than-the-extension.ism/manifest(format=mpd-time-csf)',
type: 'mpd' }}
Other protocols
The following other types are supported on some platforms, but aren't fully documented yet:
content://, ms-appx://, ms-appdata://, assets-library://
Playing only a portion of the video (start & end time)
Provide an optional startTime and/or endTime for the video. Value is in milliseconds. Useful when you want to play only a portion of a large video.
Example
source={{ uri: 'https://bitdash-a.akamaihd.net/content/sintel/hls/playlist.m3u8', startTime: 36012, endTime: 48500 }}
source={{ uri: 'https://bitdash-a.akamaihd.net/content/sintel/hls/playlist.m3u8', startTime: 36012 }}
source={{ uri: 'https://bitdash-a.akamaihd.net/content/sintel/hls/playlist.m3u8', endTime: 48500 }}
Platforms: iOS, Android
Overriding the metadata of a source
Provide an optional title, subtitle and/or description properties for the video.
Useful when to adapt the tvOS playback experience.
Example:
source={{
uri: 'https://bitdash-a.akamaihd.net/content/sintel/hls/playlist.m3u8',
title: 'Custom Title',
subtitle: 'Custom Subtitle',
description: 'Custom Description'
}}
Platforms: tvOS

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 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.
Note: Due to iOS limitations, sidecar text tracks are not compatible with Airplay. If textTracks are specified, AirPlay support will be automatically disabled.
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"

Methods
Methods operate on a ref to the Video element. You can create a ref using code like:
return (
<Video source={...}
ref={ref => (this.player = ref)} />
);
dismissFullscreenPlayer
dismissFullscreenPlayer()
Take the player out of fullscreen mode.
Example:
this.player.dismissFullscreenPlayer();
Platforms: Android, iOS
presentFullscreenPlayer
presentFullscreenPlayer()
Put the player in fullscreen mode.
On iOS, this displays the video in a fullscreen view controller with controls.
On Android, 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, iOS
save
save(): Promise
Save video to your Photos with current filter prop. Returns promise.
Example:
let response = await this.player.save();
let path = response.uri;
Notes:
- Currently only supports highest quality export
- Currently only supports MP4 export
- Currently only supports exporting to user's cache directory with a generated UUID filename.
- User will need to remove the saved video through their Photos app
- Works with cached videos as well. (Checkout video-caching example)
- If the video is has not began buffering (e.g. there is no internet connection) then the save function will throw an error.
- If the video is buffering then the save function promise will return after the video has finished buffering and processing.
Future:
- Will support multiple qualities through options
- Will support more formats in the future through options
- Will support custom directory and file name through options
Platforms: iOS
restoreUserInterfaceForPictureInPictureStopCompleted
restoreUserInterfaceForPictureInPictureStopCompleted(restored)
This function corresponds to the completion handler in Apple's restoreUserInterfaceForPictureInPictureStop. IMPORTANT: This function must be called after onRestoreUserInterfaceForPictureInPictureStop is called.
Example:
this.player.restoreUserInterfaceForPictureInPictureStopCompleted(true);
Platforms: 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. Once completed, the onSeek event will be called.
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
pause
pause(): Promise<void>
Pause the video.
Example:
this.player.pause();
Platforms: Android, iOS
play
play(): Promise<void>
Play the video.
Example:
this.player.play();
Platforms: Android, iOS
Static methods
Video Decoding capabilities
A module embed in ReactNativeVideo allow to query device supported feature. To use it include the module as following:
import { VideoDecoderProperties } from '@ifs/react-native-video-enhanced'
Platforms: Android
getWidevineLevel
Indicates whether the widevine level supported by device.
Possible results:
- 0 - unable to determine widevine support (typically not supported)
- 1, 2, 3 - Widevine level supported
Platforms: Android
Example:
VideoDecoderProperties.getWidevineLevel().then((widevineLevel) => {
...
}
isCodecSupported
Indicates whether the provided codec is supported level supported by device.
parameters:
- mimetype: mime type of codec to query
- width, height: resolution to query
Possible results:
hardware- codec is supported by hardwaresoftware- codec is supported by software onlyunsupported- codec is not supported
Example:
VideoDecoderProperties.isCodecSupported('video/avc', 1920, 1080).then(
...
}
Platforms: Android
isHEVCSupported
Helper which Indicates whether the provided HEVC/1920*1080 is supported level supported by device. It uses isCodecSupported internally.
Example:
VideoDecoderProperties.isHEVCSupported().then((hevcSupported) => {
...
}
iOS App Transport Security
- By default, iOS will only load encrypted (https) urls. If you want to load content from an unencrypted (http) source, you will need to modify your Info.plist file and add the following entry:
For more detailed info check this article
Audio Mixing
At some point in the future, react-native-video will include an Audio Manager for configuring how videos mix with other apps playing sounds on the device.
On iOS, if you would like to allow other apps to play music over your video component, make the following change:
AppDelegate.m
#import <AVFoundation/AVFoundation.h> // import
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
...
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryAmbient error:nil]; // allow
...
}
You can also use the ignoreSilentSwitch prop.
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 allows loading image resources shared across iOS and Android without touching native code. As of RN 0.31 the same is true of mp4 video assets for Android. As of RN 0.33 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 )
Examples
-
See an [Example integration][1] in
react-native-loginnote that this example uses an older version of this library, before we usedexport default-- if you userequireyou will need to dorequire('react-native-video').defaultas per instructions above. -
Try the included [VideoPlayer example][2] yourself:
git clone git@github.com:react-native-community/react-native-video.git cd react-native-video/example npm install open ios/VideoPlayer.xcodeprojThen
Cmd+Rto 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 6.0.0
iOS
In your project Podfile add support for static dependency linking. This is required to support the new Promises subdependency in the iOS swift conversion.
Add use_frameworks! :linkage => :static just under platform :ios in your ios project Podfile.
See the example ios project for reference
Version 5.0.0
Probably you want to update your gradle version:
gradle-wrapper.properties
- distributionUrl=https\://services.gradle.org/distributions/gradle-3.3-all.zip
+ distributionUrl=https\://services.gradle.org/distributions/gradle-5.1.1-all.zip
android/app/build.gradle
From version >= 5.0.0, you have to apply this changes:
dependencies {
...
compile project(':react-native-video')
+ implementation "androidx.appcompat:appcompat:1.0.0"
- implementation "com.android.support:appcompat-v7:${rootProject.ext.supportLibVersion}"
}
android/gradle.properties
Migrating to AndroidX (needs version >= 5.0.0):
android.useAndroidX=true
android.enableJetifier=true
Version 4.0.0
Gradle 3 and target SDK 26 requirement
In order to support ExoPlayer 2.9.0, you must use version 3 or higher of the Gradle plugin. This is included by default in React Native 0.57.
ExoPlayer 2.9.0 Java 1.8 requirement
ExoPlayer 2.9.0 uses some Java 1.8 features, so you may need to enable support for Java 1.8 in your app/build.gradle file. If you get an error, compiling with ExoPlayer like:
Default interface methods are only supported starting with Android N (--min-api 24)
Add the following to your app/build.gradle file:
android {
... // Various other settings go here
compileOptions {
targetCompatibility JavaVersion.VERSION_1_8
}
}
ExoPlayer no longer detaches
When using a router like the react-navigation TabNavigator, switching between tab routes would previously cause ExoPlayer to detach causing the video player to pause. We now don't detach the view, allowing the video to continue playing in a background tab. This matches the behavior for iOS.
useTextureView now defaults to true
The SurfaceView, which ExoPlayer has been using by default has a number of quirks that people are unaware of and often cause issues. This includes not supporting animations or scaling. It also causes strange behavior if you overlay two videos on top of each other, because the SurfaceView will punch a hole through other views. Since TextureView doesn't have these issues and behaves in the way most developers expect, it makes sense to make it the default.
TextureView is not as fast as SurfaceView, so you may still want to enable SurfaceView support. To do this, you can set useTextureView={false}.
Version 3.0.0
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 target 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 = 31
buildToolsVersion = "30.0.2"
minSdkVersion = 21
targetSdkVersion = 22
}
}
If you encounter an error Could not find com.android.support:support-annotations:27.0.0. reinstall your Android Support Repository.
