Mux Data Integration with react-native-video

This is a package for using Mux Data for video QoS monitoring with a react-native-video player.

View the DemoApp/ directory to see a demo application that implements this library.

Requirements

1. A functioning react-native application that uses react-native-video.
2. react-native ~> 16.9
3. react-native-video ~> 5.0.2

Installation

Install from github in your package.json (when this is officially released then it will be availble on npm).

yarn add "https://github.com/muxinc/mux-stats-sdk-react-native-video"

OR

npm install "https://github.com/muxinc/mux-stats-sdk-react-native-video" --save

Usage

This package works by wrapping your Video component in a higher order component.

For more information about what keys can be passed into the data key in the muxOptions prop see the javascript docs.

import app from './package.json' // this is your application's package.json
import Video from 'react-native-video'; // import Video from react-native-video like you normally would
import muxReactNativeVideo from 'mux-react-native-video-sdk';

// wrap the `Video` component with Mux functionality
const MuxVideo = muxReactNativeVideo(Video);

// Pass the same props to `MuxVideo` that you would pass to the
// `Video` element. All of these props will be passed through to your underlying react-native-video component
// Include a new prop for `muxOptions`
<MuxVideo
  style={styles.video}
  source={{
    uri:
      'https://bitdash-a.akamaihd.net/content/sintel/hls/playlist.m3u8',
  }}
  controls
  muted
  muxOptions={{
    application_name: app.name,            // (required) the name of your application
    application_version: app.version,      // the version of your application (optional, but encouraged)
    data: {
      env_key: 'YOUR_ENVIRONMENT_KEY',     // (required)
      player_software_version: '5.0.2'     // (optional, but encouraged) the version of react-native-video that you are using
      player_name: 'React Native Player',  // See metadata docs for available metadata fields https://docs.mux.com/docs/web-integration-guide#section-5-add-metadata
      video_id: 'My Video Id',
      video_title: 'My awesome video',
    },
  }}
/>

Known Issues

1. The paused property does not behave as expected on Android when using the default player controls. (the onProgress event, which is something the Mux SDK needs to hook into does not fire): https://github.com/react-native-community/react-native-video/issues/1979. If you are using the paused property it will work on iOS with the default controls but if you need to use it on Android you will have to implement your own controls and set/unset the paused property yourself.
2. The player_is_fullscreen property is not reported as expected on iOS. The react-native-video callbacks for fullscreen status onFullscreenPlayerDidPresent and onFullscreenPlayerDidDismiss do not get called when entering fullscreen using the native controls: https://github.com/react-native-video/react-native-video/issues/552

Caveats

1. Upscale and downscale % metrics are not calculated because we are unable to get player width and player height measurments from react-native-video.
2. Even if we could get player width and height, we still wouldn't be able to calculate upscale and downscale % metrics for HLS sources is because of this open issue related to getting the video source width & height: https://github.com/react-native-community/react-native-video/issues/1194.
3. This library is intended for use with react-native-video when targeting iOS and Android platforms. For targeting web platforms we have other SDKs that will work better for monitiring the HTML5 video element.
4. If you are overriding react-native-video's default of 250ms for progressUpdateInterval this library will: (1) ignore your setting and revert back to 250ms (2) log a warning. This library depends on a progressUpdateInterval of 250ms in order to correctly calculate rebuffering
5. 'Seeking' events are not tracked by this SDK because of inconsistent onSeek callback behavior between iOS and Android: https://github.com/react-native-community/react-native-video/issues/1977
