The MediaRecorder.isMimeTypeSupported()
method returns a Boolean which is true
if the MIME type specified is one the user agent can record.
Syntax
var canRecord = MediaRecorder.isMimeTypeSupported
(mimeType)
Parameters
mimeType
- The mimeType 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 :(")); }
