Captions

Captions are intended for deaf and hard-of-hearing audiences. Captions are usually in the same language as the audio. Please, read the differences between captions and subtitles.

The following example uses an excerpt from the Sintel open movie, created by the Blender Foundation.

import { useState } from 'react';
import { Box, Video } from 'gestalt';

export default function Example() {
  const [playing, setPlaying] = useState(false);
  const [volume, setVolume] = useState(1);

  return (
    <Box
      alignItems="center"
      display="flex"
      height="100%"
      justifyContent="center"
      padding={8}
    >
      <Box width={1000}>
        <Video
          aspectRatio={1024 / 435}
          captions="https://iandevlin.github.io/mdn/video-player-with-captions/subtitles/vtt/sintel-en.vtt"

        />
      </Box>
    </Box>
  );
}

Localization

Be sure to localize all text strings. Note that localization can lengthen text by 20 to 30 percent.

Video depends on DefaultLabelProvider for internal text strings. Localize the texts via DefaultLabelProvider. Learn more

import { useState } from 'react';
import { Box, DefaultLabelProvider, Video } from 'gestalt';

export default function Example() {
  const [playing, setPlaying] = useState(false);
  const [volume, setVolume] = useState(1);

Autoplay and error detection

Autoplay or automatically starting the playback of the video requires the autoplay prop. While autoplay of media serves a useful purpose, it should be used carefully and only when needed. In order to give users control over this, browsers often provide various forms of autoplay blocking.

Autoplay blocking is not applied to video elements when the source media doesn't have an audio track or is muted.

Gestalt Video provides a comprehensive API to handle gracefully autoplay blocking and prevent UI and/or client errors. The example below shows how to correctly handle autoplay error detection.

If autoplay is set, use onPlay to detect when the video starts playing and display the pause control accordingly. In case autoplay gets blocked, onPlay would never get triggered and controls will still display the play control.

onPlayError is another error-handling callback. In this case, onPlayError detects if the HTMLMediaElement.play() method fails. HTMLMediaElement.play() returns a Promise and onPlayError catches the error if the Promise is rejected. Display the pause control if any error is detected.

If autoplay is set, don't set the initial playing state to true as both will attempt to autoplay the video. We recommend setting autoplay, using onPlay to detect when the video is played and setting playing to true. If the initial playing state is set to true, don't set autoplay. If both autoplay and the initial playing state are set to true, autoplay has preference.

For more information about autoplay, check the MDN Web Docs: video, MDN Web Docs: HTMLMediaElement.autoplay, and the MDN Web Docs: Autoplay guide for media and Web Audio APIs.

import { useState } from 'react';
import { Box, Video } from 'gestalt';

export default function Example() {
  const [playing, setPlaying] = useState(false);
  const [volume, setVolume] = useState(1);

  return (
    <Box
      alignItems="center"
      display="flex"
      height="100%"
      justifyContent="center"
      padding={8}
    >
      <Box width={300}>
        <Video
          aspectRatio={540 / 960}
          autoplay
          controls
          loop
          onControlsPause={() => setPlaying(false)}
          onControlsPlay={() => setPlaying(true)}
          onEnded={() => setPlaying(false)}
          onPlay={() => setPlaying(true)}
          onPlayError={({ error }) => error && setPlaying(false)}
          onVolumeChange={(e) => setVolume(e.volume)}
          playing={playing}
          src="https://v1.pinimg.com/videos/mc/expMp4/c8/37/71/c83771d856bc1ee12e2d2f81083df9d4_t1.mp4"
          volume={volume}
        />
      </Box>
    </Box>
  );
}

Video controls

Video components can show a control bar to users in order to allow them access to certain features such as play/pause, timestamps, mute, and fullscreen. Pass in the controls prop to make them appear. The Video controls are custom; they aren't the native video controls.

import { useState } from 'react';
import { Box, Flex, IconButton, Label, Switch, Text, Video } from 'gestalt';

export default function Example() {
  const [showControls, setShowControls] = useState(false);
  const [playing, setPlaying] = useState(false);
  const [volume, setVolume] = useState(1);

  return (
    <Box
      alignItems="center"
      display="flex"
      height="100%"
      justifyContent="center"
      padding={8}
    >
      <Flex alignItems="center" direction="column" gap={{ column: 2, row: 0 }}>
        <Flex alignItems="center" gap={{ row: 2, column: 0 }}>
          <Box paddingX={2}>
            <Label htmlFor="video">
              <Text>Show built-in Video controls</Text>
            </Label>
          </Box>
          <Switch
            id="video"
            onChange={() => setShowControls((value) => !value)}
            switched={showControls}
          />
        </Flex>
        <Box width={300}>
          <Video
            aspectRatio={540 / 960}
            controls={showControls}
            onControlsPause={() => setPlaying(false)}
            onControlsPlay={() => setPlaying(true)}
            onEnded={() => setPlaying(false)}
            onPlay={() => setPlaying(true)}
            onPlayError={({ error }) => error && setPlaying(false)}
            onVolumeChange={(e) => setVolume(e.volume)}
            playing={playing}
            poster="https://i.pinimg.com/videos/thumbnails/originals/c8/37/71/c83771d856bc1ee12e2d2f81083df9d4.0000000.jpg"
            src="https://v1.pinimg.com/videos/mc/expMp4/c8/37/71/c83771d856bc1ee12e2d2f81083df9d4_t1.mp4"
            volume={volume}
          >
            {!showControls ? (
              <Box
                alignItems="center"
                dangerouslySetInlineStyle={{
                  __style: { backgroundColor: 'rgb(0 0 0 / 0.3)' },
                }}
                display="flex"
                height="100%"
                justifyContent="center"
                width="100%"
              >
                <IconButton
                  accessibilityLabel="Play video"
                  bgColor="white"
                  icon="play"
                  size="lg"
                />
              </Box>
            ) : null}
          </Video>
        </Box>
      </Flex>
    </Box>
  );
}

With children

Video component can show components in the children prop on top of the html video element, while under the controls.
The children of Video aren't same as the children of the html video element; they're "outside" the html video element.

import { useState } from 'react';
import { Box, IconButton, Video } from 'gestalt';

export default function Example() {
  const [playing, setPlaying] = useState(false);
  const [volume, setVolume] = useState(1);

  return (
    <Box
      alignItems="center"
      display="flex"
      height="100%"
      justifyContent="center"
      padding={8}
    >
      <Box width={300}>
        <Video
          aspectRatio={540 / 960}
          controls
          onControlsPause={() => setPlaying(false)}
          onControlsPlay={() => setPlaying(true)}
          onEnded={() => setPlaying(false)}
          onPlay={() => setPlaying(true)}
          onPlayError={({ error }) => error && setPlaying(false)}
          onVolumeChange={(e) => setVolume(e.volume)}
          playing={playing}
          src="https://v1.pinimg.com/videos/mc/expMp4/c8/37/71/c83771d856bc1ee12e2d2f81083df9d4_t1.mp4"
          volume={volume}
        >
          <Box
            alignItems="center"
            dangerouslySetInlineStyle={{
              __style: { backgroundColor: 'rgb(0 0 0 / 0.3)' },
            }}
            display="flex"
            height="100%"
            justifyContent="center"
            width="100%"
          >
            <IconButton
              accessibilityLabel="Delete video"
              bgColor="white"
              icon="trash-can"
              size="lg"
            />
          </Box>
        </Video>
      </Box>
    </Box>
  );
}

Video updates

Video is robust enough to handle any updates, such as changing the source, volume, or speed.

import { useState } from 'react';
import { Box, Button, Flex, Label, Text, TextField, Video } from 'gestalt';

export default function Example() {
  const [input, setInput] = useState(
    'https://v1.pinimg.com/videos/mc/expMp4/ce/b4/cc/ceb4cc8c4889a86432a65884c147021f_t1.mp4'
  );
  const [playbackRate, setPlaybackRate] = useState(1);
  const [playing, setPlaying] = useState(false);
  const [src, setSrc] = useState(
    'https://v1.pinimg.com/videos/mc/expMp4/c8/37/71/c83771d856bc1ee12e2d2f81083df9d4_t1.mp4'
  );
  const [volume, setVolume] = useState(1);

  return (
    <Box display="flex" height="100%" justifyContent="center" padding={8}>
      <Flex direction="column" gap={{ column: 2, row: 0 }} width="100%">
        <Label htmlFor="video-source">
          <Text>Video source URL</Text>
        </Label>
        <Flex alignItems="center" gap={{ row: 2, column: 0 }} width="100%">
          <Flex.Item flex="grow">
            <TextField
              id="video-source"
              onChange={({ value }) => setInput(value)}
              value={input}
            />
          </Flex.Item>
          <Button color="red" onClick={() => setSrc(input)} text="Submit" />
        </Flex>
        <Flex gap={{ column: 0, row: 2 }}>
          <Button
            onClick={() => setVolume(volume === 0 ? 1 : 0)}
            text={volume === 0 ? 'Unmute' : 'Mute'}
          />
          <Button
            onClick={() =>
              setPlaybackRate((value) => (value >= 1 ? value / 2 : 0.5))
            }
            text="Playback x0.5"
          />
          <Button
            onClick={() =>
              setPlaybackRate((value) => (value < 8 ? value * 2 : 16))
            }
            text="Playback x2"
          />
        </Flex>
        <Box width={300}>
          <Video
            aspectRatio={540 / 960}
            controls
            loop
            onControlsPause={() => setPlaying(false)}
            onControlsPlay={() => setPlaying(true)}
            onPlay={() => setPlaying(true)}
            onPlayError={({ error }) => error && setPlaying(false)}
            onVolumeChange={(e) => setVolume(e.volume)}
            playbackRate={playbackRate}
            playing={playing}
            src={src}
            volume={volume}
          />
        </Box>
      </Flex>
    </Box>
  );
}

Multiple video sources

Not all browsers support the same video encoding types. If you have multiple video file sources, you can pass them as a list to Video in the order you want the HTML video tag to use as fallbacks.

import { useState } from 'react';
import { Box, Video } from 'gestalt';

export default function Example() {
  const [playing, setPlaying] = useState(false);
  const [volume, setVolume] = useState(1);

  return (
    <Box
      alignItems="center"
      display="flex"
      height="100%"
      justifyContent="center"
      padding={8}
    >
      <Box width={500}>
        <Video
          aspectRatio={426 / 240}
          controls
          onControlsPause={() => setPlaying(false)}
          onControlsPlay={() => setPlaying(true)}
          onEnded={() => setPlaying(false)}
          onPlay={() => setPlaying(true)}
