MediaRecorder: isTypeSupported() static method

The isTypeSupported() static method of the MediaRecorder interface returns a Boolean which is true if the MIME media type specified is one the user agent should be able to successfully record.

Syntax

js
MediaRecorder.isTypeSupported(mimeType)

Parameters

mimeType

The MIME media type to check.

Return value

A Boolean, true if the MediaRecorder implementation is capable of recording Blob objects for the specified MIME type. Recording may still fail if there are insufficient resources to support the recording and encoding process. If the value is false, the user agent is incapable of recording the specified format.

Examples

js
const types = [
  "video/webm",
  "audio/webm",
  "video/webm;codecs=vp8",
  "video/webm;codecs=daala",
  "video/webm;codecs=h264",
  "audio/webm;codecs=opus",
  "video/mpeg",
];

for (const type of types) {
  console.log(
    `Is ${type} supported? ${
      MediaRecorder.isTypeSupported(type) ? "Maybe!" : "Nope :("
    }`,
  );
}
