const RecordView = () => {
    const {status, error, startRecording, stopRecording, mediaBlobUrl, mediaBlob} = useReactMediaRecorder({audio:true})

  return (
        <div>
          <p>{status}</p>
          <button onClick={startRecording}>Start Recording</button>

Options / Props

audio

Can be either a boolean value or a MediaTrackConstraints object.

type: boolean or object
default: true

blobPropertyBag

From MDN:
An optional BlobPropertyBag dictionary which may specify the following two attributes (for the mediaBlob):

• type, that represents the MIME type of the content of the array that will be put in the blob.
• endings, with a default value of "transparent", that specifies how strings containing the line ending character \n are to be written out. It is one of the two values: "native", meaning that line ending characters are changed to match host OS filesystem convention, or "transparent", meaning that endings are stored in the blob without change

type: object
default:
if video is enabled,

{
   type: "video/mp4"
}

if there's only audio is enabled,

{
  type: "audio/wav"
}

mediaRecorderOptions

An optional options object that will be passed to MediaRecorder. Please note that if you specify the MIME type via either audio or video prop and through this mediaRecorderOptions, the mediaRecorderOptions have higher precedence.

type: object
default: {}

onStop

A function that would get invoked when the MediaRecorder stops. It'll provide the blob url as its param.

type: function(blobUrl: string)
default: () => null

render

A function which accepts an object containing fields: status, startRecording, stopRecording andmediaBlob. This function would return a react element/component.

type: function
default: () => null

screen

A boolean value. Lets you to record your current screen. Not all browsers would support this. Please check here for the availability. Please note that at the moment, the MediaRecorder won't record two alike streams at a time, if you provide both screen and video prop, the screen capturing will take precedence than the video capturing. But, you can provide the video prop (as the MediaTrackConstraints) which will then utilized by screen capture (for example, height, width etc..)

video

Can be either a boolean value or a MediaTrackConstraints object.

type: boolean or object
default: false

• media_in_use
• invalid_media_constraints
• no_constraints
• recorder_error

• media_aborted
• permission_denied
• no_specified_media_found
• media_in_use
• invalid_media_constraints
• no_constraints
• recorder_error
• idle
• acquiring_media

startRecording

A function, which starts recording when invoked.

pauseRecording

A function, which pauses the recording when invoked.
