MediaRecorder.isTypeSupported

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

Syntax

var canRecord = MediaRecorder.isTypeSupported(mimeType)

Parameters

mimeType
The MIME media type to check.

Return value

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.

Example

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

for (var i in types) {
  console.log( "Is " + types[i] + " supported? " + (MediaRecorder.isTypeSupported(types[i]) ? "Maybe!" : "Nope :("));
}
