sources:

interface sources {
  [key in ('ld' | 'sd' | 'hd' | 'fhd')]: {
    bitrate?: number
    duration?: number
    format?: string
    height?: number
    width?: number
    play_url: string
    size?: number
  }
}

progressDots:

type ProgressDots = ProgressDotItem[]

interface ProgressDotItem {
  startTime: number (second)
}

Standalone mode

The standalone mode indicates that the player is the only content of the document and is generally used as an internal page of the iframe.

The behavior in standalone mode is:

• Will set the title of the document to the title of the video.
• Enable shortcut support (listen to the keydown event on document).
• Will send a message to the parent page, the parent page can listen to these events and then communicate with the player.

Cross-window message with player

use griffith-message

Build Options

We rely on hls.js to play M3U8 format video. If you don't want to build hls.js into your app, you can use the following methods:

Use the external option of webpack

Add the following options to your webpack configuration:

externals: {
  'hls.js/dist/hls.light.min': 'Hls',
},

Then manually load hls.js in html:

<script src="https://unpkg.com/hls.js@0.7.11/dist/hls.light.min.js"></script>

Remove M3U8 support

If you are sure that you will not support M3U8 video, you may not use hls.js.

Add the following options to your webpack configuration:

resolve: {
  alias: {
    'griffith-hls': false,
  },
},

Note: In this case, an error warning is issued if an attempt is made to play an M3U8 video.

technical details

format	parse	Media Source Extension (MSE)
M3U8	HLS	hls.js
mp4	griffith-mp4	griffith-mp4.js

Confirm whether HLS is supported

document.createElement('video').canPlayType('application/vnd.apple.mpegURL')

Currently supported browsers are: Safari, Edge, Chrome, Chrome for Android.

Confirm whether MSE is supported

hls.js's Hls.isSupported() method is used to determine whether MSE is supported.

Code

function getMediaSource() {
  if (typeof window !== 'undefined') {
    return window.MediaSource || window.WebKitMediaSource
  }
}

function isSupported() {
  const mediaSource = getMediaSource()
  const sourceBuffer = window.SourceBuffer || window.WebKitSourceBuffer
  const isTypeSupported =
    mediaSource &&
    typeof mediaSource.isTypeSupported === 'function' &&
    mediaSource.isTypeSupported('video/mp4; codecs="avc1.42E01E,mp4a.40.2"')

  // if SourceBuffer is exposed ensure its API is valid
  // safari and old version of Chrome doe not expose SourceBuffer globally so checking SourceBuffer.prototype is impossible
  const sourceBufferValidAPI =
    !sourceBuffer ||
    (sourceBuffer.prototype &&
      typeof sourceBuffer.prototype.appendBuffer === 'function' &&
      typeof sourceBuffer.prototype.remove === 'function')
  return !!isTypeSupported && !!sourceBufferValidAPI
}

Video quality switching

The API returns multiple quality URLs, users can manually switch video quality, and the player can automatically switch video quality.
