Expo Video (expo-video)A library that provides an API to implement video playback in apps.
expo-video is a cross-platform, performant video component for React Native and Expo with Web support.
Known issues Android
When two VideoView components are overlapping and have the contentFit prop set to cover, one of the videos may be displayed out of bounds. This is a known upstream issue. To work around this issue, use the surfaceType prop and set it to textureView.
Installation
- npx expo install expo-videoIf you are installing this in an existing React Native app, make sure to install expo in your project.
Configuration in app config
You can configure expo-video using its built-in config plugin if you use config plugins in your project (Continuous Native Generation (CNG)). The plugin allows you to configure various properties that cannot be set at runtime and require building a new app binary to take effect. If your app does not use CNG, then you'll need to manually configure the library.
Example app.json with config plugin
{ "expo": { "plugins": [ [ "expo-video", { "supportsBackgroundPlayback": true, "supportsPictureInPicture": true } ] ], } }
Configurable properties
| Name | Default | Description |
|---|---|---|
supportsBackgroundPlayback | undefined | Only for: iOS A boolean value to enable background playback on iOS. If |
supportsPictureInPicture | undefined | A boolean value to enable Picture-in-Picture on Android and iOS. If |
Usage
Here's a simple example of a video with a play and pause button.
import { useEvent } from 'expo'; import { useVideoPlayer, VideoView } from 'expo-video'; import { StyleSheet, View, Button } from 'react-native'; const videoSource = 'https://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4'; export default function VideoScreen() { const player = useVideoPlayer(videoSource, player => { player.loop = true; player.play(); }); const { isPlaying } = useEvent(player, 'playingChange', { isPlaying: player.playing }); return ( <View style={styles.contentContainer}> <VideoView style={styles.video} player={player} allowsFullscreen allowsPictureInPicture /> <View style={styles.controlsContainer}> <Button title={isPlaying ? 'Pause' : 'Play'} onPress={() => { if (isPlaying) { player.pause(); } else { player.play(); } }} /> </View> </View> ); } const styles = StyleSheet.create({ contentContainer: { flex: 1, padding: 10, alignItems: 'center', justifyContent: 'center', paddingHorizontal: 50, }, video: { width: 350, height: 275, }, controlsContainer: { padding: 10, }, });
Receiving events
The changes in properties of the VideoPlayer do not update the React state. Therefore, to display the information about the current state of the VideoPlayer, it is necessary to listen to the events it emits.
The event system is based on the EventEmitter class and hooks from the expo package. There are a few ways to listen to events:
useEvent hook
Creates a listener that will return a stateful value that can be used in a component. It also cleans up automatically when the component unmounts.
import { useEvent } from 'expo'; // ... Other imports, definition of the component, creating the player etc. const { status, error } = useEvent(player, 'statusChange', { status: player.status }); // Rest of the component...
useEventListener hook
Built around the Player.addListener and Player.removeListener methods, creates an event listener with automatic cleanup.
import { useEventListener } from 'expo'; // ...Other imports, definition of the component, creating the player etc. useEventListener(player, 'statusChange', ({ status, error }) => { setPlayerStatus(status); setPlayerError(error); console.log('Player status changed: ', status); }); // Rest of the component...
Player.addListener method
Most flexible way to listen to events, but requires manual cleanup and more boilerplate code.
// ...Imports, definition of the component, creating the player etc. useEffect(() => { const subscription = player.addListener('statusChange', ({ status, error }) => { setPlayerStatus(status); setPlayerError(error); console.log('Player status changed: ', status); }); return () => { subscription.remove(); }; }, []); // Rest of the component...
Playing local media from the assets directory
expo-video supports playing local media loaded using the require function. You can use the result as a source directly, or assign it to the assetId parameter of a VideoSource if you also want to configure other properties.
import { VideoSource } from 'expo-video'; const assetId = require('./assets/bigbuckbunny.mp4'); const videoSource: VideoSource = { assetId, metadata: { title: 'Big Buck Bunny', artist: 'The Open Movie Project', }, }; const player1 = useVideoPlayer(assetId); // You can use the `asset` directly as a video source const player2 = useVideoPlayer(videoSource);
Preloading videos
While another video is playing, a video can be loaded before showing it in the view. This allows for quicker transitions between subsequent videos and a better user experience.
To preload a video, you have to create a VideoPlayer with a video source. Even when the player is not connected to a VideoView, it will fill the buffers. Once it is connected to the VideoView, it will be able to start playing without buffering.
In some cases, it is beneficial to preload a video later in the screen lifecycle. In that case, a VideoPlayer with a null source should be created. To start preloading, replace the player source with a video source using the replace() function.
Here is an example of how to preload a video:
import { useVideoPlayer, VideoView, VideoSource } from 'expo-video'; import { useState, useCallback } from 'react'; import { StyleSheet, Text, TouchableOpacity, View } from 'react-native'; const bigBuckBunnySource: VideoSource = 'https://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4'; const elephantsDreamSource: VideoSource = 'https://commondatastorage.googleapis.com/gtv-videos-bucket/sample/ElephantsDream.mp4'; export default function PreloadingVideoPlayerScreen() { const player1 = useVideoPlayer(bigBuckBunnySource, player => { player.play(); }); const player2 = useVideoPlayer(elephantsDreamSource, player => { player.currentTime = 20; }); const [currentPlayer, setCurrentPlayer] = useState(player1); const replacePlayer = useCallback(async () => { currentPlayer.pause(); if (currentPlayer === player1) { setCurrentPlayer(player2); player1.pause(); player2.play(); } else { setCurrentPlayer(player1); player2.pause(); player1.play(); } }, [player1, currentPlayer]); return ( <View style={styles.contentContainer}> <VideoView player={currentPlayer} style={styles.video} nativeControls={false} /> <TouchableOpacity style={styles.button} onPress={replacePlayer}> <Text style={styles.buttonText}>Replace Player</Text> </TouchableOpacity> </View> ); } const styles = StyleSheet.create({ contentContainer: { flex: 1, padding: 10, alignItems: 'center', justifyContent: 'center', paddingHorizontal: 50, }, button: { alignItems: 'center', justifyContent: 'center', borderRadius: 3, paddingVertical: 8, paddingHorizontal: 12, backgroundColor: '#4630ec', }, buttonText: { fontSize: 12, fontWeight: 'bold', color: '#eeeeee', textAlign: 'center', }, video: { width: 300, height: 168.75, marginVertical: 20, }, });
Using the VideoPlayer directly
In most cases, the useVideoPlayer hook should be used to create a VideoPlayer instance. It manages the player's lifecycle and ensures that it is properly disposed of when the component is unmounted. However, in some advanced use cases, it might be necessary to create a VideoPlayer that does not get automatically destroyed when the component is unmounted.
In those cases, the VideoPlayer can be created using the createVideoPlayer function. You need be aware of the risks that come with this approach, as it is your responsibility to call the release() method when the player is no longer needed. If not handled properly, this approach may lead to memory leaks.
import { createVideoPlayer } from 'expo-video'; const player = createVideoPlayer(videoSource);
On Android, mounting multipleVideoViewcomponents at the same time with the sameVideoPlayerinstance will not work due to a platform limitation.
Caching videos
If your app frequently replays the same video, caching can be utilized to minimize network usage and enhance user experience, albeit at the cost of increased device storage usage. expo-video supports video caching on Android and iOS platforms. This feature can be activated by setting the useCaching property of a VideoSource object to true.
The cache is persistent and will be cleared on a least-recently-used basis once the preferred size is exceeded. Furthermore, the system can clear the cache due to low storage availability, so it's not advisable to depend on the cache to store critical data.
The cache functions offline. If a portion or the entirety of a video is cached, it can be played from the cache even when the device is offline until the cached data is exhausted.
Due to platform limitations, the cache cannot be used with HLS video sources on iOS. Caching DRM-protected videos is not supported on Android and iOS.
Managing the cache
- The preferred cache size in bytes can be defined using the
setVideoCacheSizeAsyncfunction. The default cache size is 1GB. - The
getCurrentVideoCacheSizecan be used to get the current storage occupied by the cache in bytes. - All cached videos can be cleared using the
clearVideoCacheAsyncfunction.

VideoPlayerClasses
Type: Class extends SharedObject<VideoPlayerEvents>
A class that represents an instance of the video player.
VideoPlayer Properties
boolean • Default: trueDetermines whether the player should allow external playback.
AudioMixingMode • Default: 'auto'Determines how the player will interact with other audio playing in the system.
union • Default: nullSpecifies the audio track currently played by the player. null when no audio is played.
Acceptable values are: null | AudioTrack
AudioTrack[]An array of audio tracks available for the current video.
SubtitleTrack[]An array of subtitle tracks available for the current video.
VideoTrack[]An array of video tracks available for the current video.
On iOS, when using a HLS source, make sure that the uri contains
.m3u8extension or that thecontentTypeproperty of theVideoSourcehas been set to'hls'. Otherwise, the video tracks will not be available.
numberFloat value indicating how far the player has buffered the video in seconds.
This value is 0 when the player has not buffered up to the current playback time. When it's impossible to determine the buffer state (for example, when the player isn't playing any media), this value is -1.
BufferOptionsSpecifies buffer options which will be used by the player when buffering the video.
You should provide a
BufferOptionsobject when setting this property. Setting individual buffer properties is not supported.
unionThe exact timestamp when the currently displayed video frame was sent from the server,
based on the EXT-X-PROGRAM-DATE-TIME tag in the livestream metadata.
If this metadata is missing, this property will return null.
Acceptable values are: null | number
unionFloat value indicating the latency of the live stream in seconds.
If a livestream doesn't have the required metadata, this will return null.
Acceptable values are: null | number
numberFloat value indicating the current playback time in seconds.
If the player is not yet playing, this value indicates the time position
at which playback will begin once the play() method is called.
Setting currentTime to a new value seeks the player to the given time.
Note that frame accurate seeking may incur additional decoding delay which can impact seeking performance.
Consider using the seekBy function if the time does not have to be set precisely.
numberFloat value indicating the duration of the current video in seconds.
booleanIndicates whether the player is currently playing back the media to an external device via AirPlay.
booleanBoolean value indicating whether the player is currently playing a live stream.

Acceptable values are: null | VideoTrack
VideoPlayer Methods
| Parameter | Type |
|---|---|
| times | number | number[] |
| options(optional) | VideoThumbnailOptions |
Generates thumbnails from the currently played asset. The thumbnails are references to native images,
thus they can be used as a source of the Image component from expo-image.
Promise<VideoThumbnail[]>| Parameter | Type |
|---|---|
| source | VideoSource |
| disableWarning(optional) | boolean |
Replaces the current source with a new one.
On iOS, this method loads the asset data synchronously on the UI thread and can block it for extended periods of time. Use
replaceAsyncto load the asset asynchronously and avoid UI lags.
This method will be deprecated in the future.
void| Parameter | Type |
|---|---|
| source | VideoSource |
Replaces the current source with a new one, while offloading loading of the asset to a different thread.
On Android and Web, this method is equivalent to
replace.
Promise<void>| Parameter | Type |
|---|---|
| seconds | number |
Seeks the playback by the given number of seconds. The time to which the player seeks may differ from the specified requested time for efficiency,
depending on the encoding and what is currently buffered by the player. Use this function to implement playback controls that seek by specific amount of time,
in which case, the actual time usually does not have to be precise. For frame accurate seeking, use the currentTime property.
voidType: Class extends SharedRef<'image'>
Represents a video thumbnail that references a native image.
Instances of this class can be passed as a source to the Image component from expo-image.
VideoThumbnail Properties
