Promise based zero dependency webcam library for React. Select video and audio input for one or multiple concurrent recordings using any mix of video and audio source.
DEMO
Note version 1.0 is a complete rewrite so you will need to make some changes if updating.
Add package
npm i react-record-webcam
Usage
import { useRecordWebcam } from 'react-record-webcam'
...
const {
activeRecordings,
createRecording,
openCamera,
startRecording,
stopRecording,
} = useRecordWebcam()
const example = async () => {
try {
const recording = await createRecording();
if (!recording) return;
await openCamera(recording.id);
await startRecording(recording.id);
await new Promise((resolve) => setTimeout(resolve, 3000));
await stopRecording(recording.id);
} catch (error) {
console.error({ error });
}
};
return (
<div>
<button onClick={example}>Start</button>
{activeRecordings.map(recording => (
<div key={recording.id}>
<video ref={recording.webcamRef} autoPlay muted />
<video ref={recording.previewRef} autoPlay muted loop />
</div>
))}
</div>
)
...

Passing options
Pass options either when initializing the hook or at any point in your application logic using applyOptions
.
const options = { fileName: string, fileType: string, mimeType: string }
const { ... } = useRecordWebcam(options)
const { applyOptions } = useRecordWebcam()
applyOptions(recording.id: string, options)
Option | default value |
---|
fileName | timestamp |
fileType | webm |
mimeType | video/webm;codecs=vp9 |
If you want to use a specific video/audio codec you can pass this in the mimeType
. For example:
'video/webm;codecs=vp9'
'video/webm;codecs=vp8'
'video/webm;codecs=h264'
'video/x-matroska;codecs=avc1'
Please check that the browser supports the selected codec.
Passing recorder options
Pass recorder options when initializing the hook.
const recorderOptions: { audioBitsPerSecond: number, videoBitsPerSecond: number }
const { ... } = useRecordWebcam(recorderOptions)
Link to MDN for supported MediaOptions.
Passing recording constraints
const constraints: { aspectRatio: number, height: number, width: number }
const { ... } = useRecordWebcam(constraints)
const { applyConstraints } = useRecordWebcam()
applyConstraints(recording.id: string, constraints)
Link to MDN for supported MediaConstraints.
