Expo Video

GitHub

npm

A library that provides an API to implement video playback in apps.

Android

iOS

Web

expo-video is a new, experimental library that aims to replace the Video component from expo-av with a more modern and reliable implementation. If you are looking for a more stable API, use expo-av until this library has stabilized.

To provide quicker updates, expo-video is currently unsupported in Expo Go and Snack. To use it, create a development build.

expo-video is a cross-platform, performant video component for React Native and Expo with Web support.

Installation

Terminal

- npx expo install expo-video

If you are installing this in an existing React Native app (bare workflow), start by installing expo in your project. Then, follow the additional instructions as mentioned by library's README under "Installation in bare React Native projects" section.

Usage

Here's a simple example of a video with a play and pause button.

Video

import { useVideoPlayer, VideoView } from 'expo-video';
import { useEffect, useRef, useState } from 'react';
import { PixelRatio, StyleSheet, View, Button } from 'react-native';

const videoSource =
  'https://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4';

export default function VideoScreen() {
  const ref = useRef(null);
  const [isPlaying, setIsPlaying] = useState(true);
  const player = useVideoPlayer(videoSource, player => {
    player.loop = true;
    player.play();
  });

  useEffect(() => {
    const subscription = player.addListener('playingChange', isPlaying => {
      setIsPlaying(isPlaying);
    });

    return () => {
      subscription.remove();
    };
  }, [player]);

  return (
    <View style={styles.contentContainer}>
      <VideoView
        ref={ref}
        style={styles.video}
        player={player}
        allowsFullscreen
        allowsPictureInPicture
      />
      <View style={styles.controlsContainer}>
        <Button
          title={isPlaying ? 'Pause' : 'Play'}
          onPress={() => {
            if (isPlaying) {
              player.pause();
            } else {
              player.play();
            }
            setIsPlaying(!isPlaying);
          }}
        />
      </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,
  },
});

Classes

`VideoPlayer`

Type: Class extends _default<VideoPlayerEvents>

A class that represents an instance of the video player.

VideoPlayer Properties

`currentTime`

Type: number

Float 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.

`duration`

Type: number

Float value indicating the duration of the current video in seconds.

This property is get-only

`isLive`

Type: boolean

Boolean value indicating whether the player is currently playing a live stream.

This property is get-only

`loop`

Type: boolean

Determines whether the player should automatically replay after reaching the end of the video.

`muted`

Type: boolean

Boolean value whether the player is currently muted. Setting this property to true/false will mute/unmute the player.

`playbackRate`

Type: number

Float value between 0 and 16 indicating the current playback speed of the player.

`playing`

Type: boolean

Boolean value whether the player is currently playing.

This property is get-only, use play and pause methods to control the playback.

Only for:

Android

iOS

`preservesPitch`

Type: boolean

Boolean value indicating if the player should correct audio pitch when the playback speed changes.
