React Native makes it possible to build mobile apps for iOS and Android using a single JavaScript codebase. This flexibility has made it a popular choice among developers who want to streamline their workflow and reach users across platforms. Still, adding and managing video in React Native can be a challenge. Developers often run into issues with performance, file size, and ensuring smooth playback on different devices.
Playing video in a React Native application is most commonly accomplished using the react-native-video library, which provides a versatile Video component for rendering local files, remote URLs, and streaming formats like HLS or DASH.
This article will guide you through installing and linking the library, importing and using the Video component, and configuring key props, handling both local and remote video sources, working with streaming protocols, and highlight considerations for DRM-protected content and permissions. For those needing more advanced or custom controls, we’ll mention react-native-video-controls and show how to handle playback events.

What Is React Native?
React Native is an open-source framework that enables developers to create mobile applications using JavaScript. It supports both iOS and Android, making it possible to have a single codebase for both. React Native combines native app development with React, a JavaScript library for building user interfaces. This approach enables a faster development cycle and a high-quality user experience across both platforms.
The framework leverages native components for rendering and offers access to platform-specific functionalities, ensuring that apps built with React Native perform as well as native apps. React Native also supports the concept of “hot reloading,” where changes in the code are immediately visible in the app without a full rebuild, significantly speeding up development.
What Is the React-Native-Video Library?
The react-native-video library is an open-source project that extends React Native’s capabilities for handling video playback. It provides a unified, easy-to-use API for integrating video playback in iOS and Android applications. This library supports a range of video formats and offers features such as playback control, track selection, volume control, and fullscreen playback.
The react-native-video library also offers advanced features such as adaptive bitrate streaming (HLS and MPEG-DASH), which optimizes video quality for various network conditions and device capabilities. The library’s support for closed captions and subtitles helps ensure accessibility, while its event hooks enable developers to create custom controls and interactions.
Key Features of react-native-video
- Supports Local and Remote Sources: Play videos from local files (using require()) or remote URLs.
- Streaming Support: Handles all video formats that are supported by Android and iOS, including HLS and DASH.
- Customizable Controls: Use the built-in controls prop for basic playback controls, or integrate react-native-video-controls for more advanced/custom UI.
- Playback Events: Respond to events like onBuffer and onError for improved user feedback and error handling.
- DRM Support: With additional setup, supports DRM-protected content (e.g., Widevine, FairPlay).
Adding Videos to React Native with the react-native-video Library
Before adding videos to your React Native app, you need to know whether you’re aiming to develop for Android or iOS. In this tutorial, we’ll assume we’re building an application for iOS.
Install the Package
First, you need to integrate the react-native-video library into your project. Navigate to the root directory of your project and execute the following command:
npm install --save react-native-video
This command fetches and installs the react-native-video package, adding it as a dependency to your project. If you are on a Mac, there’s an additional step to ensure the native dependencies are properly linked. Run:
npx pod-install
Linking Native Dependencies
For React Native versions 0.60 and above, autolinking should handle native dependencies automatically. If you are using an older version or encounter issues, you may need to link manually:
npx react-native link react-native-video
How to Use react-native-video
We’ll use react-native-video to create a login screen that features a background video. Start by importing the Video
component from the react-native-video library into your React Native component:
import Video from 'react-native-video'; import video from '../my-video.mp4'; const MyComponent = () => { return ( <Video source={video} paused={false} style={styles.backgroundVideo} repeat={true} /> ); };
A few things to note about this code:
- By setting the
source
prop, you link the video file to be played. - The
paused
prop is set tofalse
for the video to play automatically - The
style
prop enables look and feel customization Repeat
is set totrue
to loop the video in the background
Use Other Component Props in react-native-video
While the example above showcases a basic setup, the react-native-video library has many other props to tailor the video experience to your needs. Some noteworthy props include:
allowsExternalPlayback
– enables control over the video through external devices like AirPlay or HDMI (iOS only).playInBackground
allows the audio to continue playing when the app is not in the foreground. This can be useful when you need to maintain audio playback in the background.poster
– sets a thumbnail image to display before the video plays.controls
– displays video controls, allowing users to interact with the playback. Note that on iOS, controls are available in fullscreen mode regardless of this setting.
Create Custom Video Controls
React Native allows you to customize video playback controls. Using React state, properties like paused
and muted
can be dynamically controlled. Let’s see how to create a custom playback control interface:
import React, { useState } from 'react'; import { View, Button, StyleSheet } from 'react-native'; import Video from 'react-native-video'; const MyVideoComponent = () => { const [paused, setPaused] = useState(true); // Control playback state const [muted, setMuted] = useState(false); // Control sound state return ( <View style={styles.container}> <Video source={require('../path/to/your/video.mp4')} // Can be a URL or a local file. paused={paused} // Control playback muted={muted} // Control sound style={styles.video} // Other props /> <View style={styles.controls}> <Button title={paused ? 'Play' : 'Pause'} onPress={() => setPaused(!paused)} /> <Button title={muted ? 'Unmute' : 'Mute'} onPress={() => setMuted(!muted)} /> </View> </View> ); }; const styles = StyleSheet.create({ container: { flex: 1, justifyContent: 'center', alignItems: 'center', }, video: { width: '100%', height: 300, }, controls: { flexDirection: 'row', justifyContent: 'center', alignItems: 'center', marginTop: 20, }, }); export default MyVideoComponent;
Note: You must add MyComponent
in the App.js
of your video application project.
This example demonstrates a straightforward way to create a play/pause and mute/unmute toggle. Here’s a breakdown of how it works:
- State management –
useState
is used to manage the paused and muted states. Thepaused
state controls whether the video is playing or paused, while themuted
state controls the sound. - Video component – the
Video
component is used to display the video. Itspaused
andmuted
props are controlled by the component’s state. - Control buttons – Two buttons are used to toggle the paused and muted states. These buttons control the playback and sound of the video.
Advanced Controls with react-native-video-controls
If you need more customizable controls than the built-in controls prop provides, consider using the react-native-video-controls package, which builds on top of react-native-video and offers a customizable UI for play, pause, seek, and more.
Invoke Methods in the Video
For an even more controlled video experience, the react-native-video library allows the invocation of several methods in the video element. This enables actions like entering fullscreen mode on demand. Here’s how:
const MyComponent = () => { const videoPlayer = React.useRef(); const goFullScreen = () => { if (videoPlayer.current) { videoPlayer.current.presentFullscreenPlayer(); } }; return ( <Video ref={ref => (videoPlayer.current = ref)} source={video} paused={false} style={styles.backgroundVideo} repeat={true} /> ); };
You can directly manipulate the video element by creating a reference to it, offering a seamless integration of video functionalities within your React Native application.
DRM and Permissions Considerations
In the event that you need to play videos that are protected by DRM, for example, Widevine or FairPlay, you might need to do some extra configuration and integrate with DRM providers. If you want your app to play videos stored on the device, don’t forget to request the necessary file system permissions on iOS and Android.
