MuxVideo

Video element for Mux-hosted HLS streams

Video element for playing Mux-hosted HLS streams. Built on hls.js with Mux-specific optimizations.

Import

pnpm add @videojs/react @videojs/mux-video

import { MuxVideo } from '@videojs/react/media/mux-video';

Load a source

The source param builds the URL for you from a playback ID, an optional custom domain, and playback params. Playback params are just camelCased Mux playback query params; for example, max_resolution becomes maxResolution.

<MuxVideo
  source={{ 
    playbackId: 'BV3YZtogl89mg9VcNBhhnHm02Y34zI1nlMuMQfAbl3dM',
    customDomain: 'media.example.com',
    playback: { maxResolution: '1080p' }
  }} 
/>

If for some reason you need a bit more control, you can use the src param with a plain ’ol URL, too:

<MuxVideo
  src="https://stream.mux.com/BV3YZtogl89mg9VcNBhhnHm02Y34zI1nlMuMQfAbl3dM.m3u8"
/>

MuxVideo ignores the same source object when it is assigned again. A new object fires sourcechange even when its values are equal, although an equivalent playback source does not reload.

MuxVideo takes Mux content two ways: a stream URL through src, or a structured source object.

<mux-video src="https://stream.mux.com/BV3YZtogl89mg9VcNBhhnHm02Y34zI1nlMuMQfAbl3dM.m3u8"></mux-video>

The source object builds the URL for you from a playback ID, an optional custom domain, and playback params. Playback params are just camelCased Mux playback query params; for example, max_resolution becomes maxResolution.

const video = document.querySelector('mux-video')!;
video.source = {
  playbackId: 'BV3YZtogl89mg9VcNBhhnHm02Y34zI1nlMuMQfAbl3dM',
  customDomain: 'media.example.com',
  playback: { maxResolution: '1080p' },
};

MuxVideo ignores the same source object when it is assigned again. A new object fires sourcechange even when its values are equal, although an equivalent playback source does not reload.

Posters and storyboards

MuxVideo derives a poster image and a storyboard from the playback ID. source.poster and source.storyboard configure the generated URLs.

When MuxVideo is inside a player, it supplies the poster for the skin to display. Set poster on the player when you want to use your own image instead.

A generated poster becomes available after MuxVideo mounts. Pass poster to the player when the image must appear in server-rendered HTML.

MuxVideo injects the derived storyboard <track> automatically and removes it when the media detects a live stream. Configure the derived URLs through the source object:

<MuxVideo
  source={{
    playbackId: 'BV3YZtogl89mg9VcNBhhnHm02Y34zI1nlMuMQfAbl3dM',
    poster: { time: 2, width: 1280 },
    storyboard: { format: 'webp' },
  }}
/>

const video = document.querySelector('mux-video')!;
video.source = {
  playbackId: 'BV3YZtogl89mg9VcNBhhnHm02Y34zI1nlMuMQfAbl3dM',
  poster: { time: 2, width: 1280 },
  storyboard: { format: 'webp' },
};

For declarative HTML, poster-time="2" reflects to source.poster.time after the src attribute is parsed.

The storyboard lives on a Mux domain, so MuxVideo has to be CORS-enabled for that cross-origin <track> to load at all. Thumbnail then fetches the sprite sheets its cues point at the same way:

<MuxVideo
  source={{ playbackId: 'BV3YZtogl89mg9VcNBhhnHm02Y34zI1nlMuMQfAbl3dM' }}
  crossOrigin="anonymous"
/>

Signed playback

For signed playback, put the playback token on source.playback.token. The token replaces every other playback param, so bake modifiers like resolution and time bounds into the token when you sign it.

Signed playback needs a separate token for each image URL. Put the thumbnail token (aud: 't') at source.poster.token and the storyboard token (aud: 's') at source.storyboard.token. If either token is missing or has the wrong audience, MuxVideo does not generate the corresponding URL.

<MuxVideo
  source={{
    playbackId: 'BV3YZtogl89mg9VcNBhhnHm02Y34zI1nlMuMQfAbl3dM',
    playback: { token: playbackToken },
    poster: { token: posterToken },
    storyboard: { token: storyboardToken },
  }}
/>

const video = document.querySelector('mux-video')!;
video.source = {
  playbackId: 'BV3YZtogl89mg9VcNBhhnHm02Y34zI1nlMuMQfAbl3dM',
  playback: { token: playbackToken },
  poster: { token: posterToken },
  storyboard: { token: storyboardToken },
};

Analytics and casting

MuxVideo plays Mux streams. It doesn’t monitor them or cast them — Mux Data and Google Cast are separate extensions you add to the player alongside it. Mux Data needs no environment key here, since Mux attributes the views to the environment that owns the playback ID:

Add @videojs/mux-data to the installation before using the telemetry component below:

pnpm add @videojs/mux-data

import { createPlayer } from '@videojs/react';
import { GoogleCast } from '@videojs/react/extensions/google-cast';
import { MuxData } from '@videojs/react/extensions/mux-data';
import { MuxVideo } from '@videojs/react/media/mux-video';
import { videoFeatures } from '@videojs/react/video';

const { Player } = createPlayer({ features: videoFeatures });

export function MuxPlayer() {
  return (
    <Player>
      <MuxVideo source={{ playbackId: 'BV3YZtogl89mg9VcNBhhnHm02Y34zI1nlMuMQfAbl3dM' }} playsInline />
      <MuxData playerSoftwareName="mux-video" />
      <GoogleCast />
    </Player>
  );
}

API Reference

Props

Accepts the standard React props for a native <video>, plus these Video.js-specific props:

Prop	Type	Default
`disableRemotePlayback`	`unknown`	`false`
Description Whether remote playback (AirPlay, Google Cast) is disabled for this media.
`preload`	`MediaPreloadType`	`'metadata'`
Description Preload type (`'none'` / `'metadata'` / `'auto'`).
`source`	`{ drm?: MuxDrmParams } \| null`	`null`
Description Structured Mux source. Setting it derives `src` from the playback ID, custom domain, and `playback` params (appended as `snake_case` query params). A `playback.token` replaces all other params — signed URLs bake them into the token. Engine options live under `engine`. A `drm.token` fills in `drm` itself: Mux's FairPlay, Widevine, and PlayReady license servers for this playback ID, so protected media plays whichever path the browser takes. License servers named alongside the token win, key by key, for content Mux does not license. `playback.maxResolution` and `playback.minResolution` are server-side: they decide which renditions Mux puts in the manifest at all. The inherited `maxAutoResolution` and `minAutoResolution` only look like their pair — those are client-side and bound which of the renditions that do arrive adaptive selection reaches for. The two halves are independent.
`src`	`string`	`''`
Description Media source URL. Setting a Mux stream URL (`https://stream.mux.com/<playback-id>.m3u8?...`) extracts the playback ID and query params into `source`; other URLs are kept as a plain `source.src`. Only playback options carry over. Mux identity comes from the URL, and the signed `poster`, `storyboard`, and `drm` tokens are scoped to a playback ID, so carrying them onto a different source would build rejected URLs.
`streamType`	`MediaStreamType`	`"unknown"`
Description Current stream type (`'on-demand'` / `'live'` / `'unknown'`).

Option	Type	Details
`drmSystems`	`DrmSystemsConfig \| undefined`
Description License servers for protected content, keyed by EME key system id. An escape hatch for licensing native playback differently from every other path: naming it replaces `source.drm` here, and nowhere else.

Ref

Forwards its ref to the rendered <video>. The ref is an HTMLVideoElement and exposes its complete native property and method API.

Events

Handle standard media events with React event props such as onPlay and onTimeUpdate. For native events without a React prop, attach a listener through the ref with addEventListener.
