constructorcljs

Constructor.

The MediaRecorder() constructor creates a new web.audio.MediaRecorder object that will record a specified web.streams.MediaStream.

stream The web.streams.MediaStream that will be recorded. This source media can come from a stream created using navigator.mediaDevices.getUserMedia() or from an <audio>, <video> or <canvas> element.

options Optional

A dictionary object that can contain the following properties:

mimeType: A MIME type specifying the format for the resulting media; you may simply specify the container format (the browser will select its preferred codecs for audio and/or video), or you may codecs and/or the profiles parameter to provide detailed information about which codecs to use and how to configure them. Applications can check in advance if a mimeType is supported by the user agent by calling MediaRecorder.isTypeSupported(). audioBitsPerSecond: The chosen bitrate for the audio component of the media. videoBitsPerSecond: The chosen bitrate for the video component of the media. bitsPerSecond: The chosen bitrate for the audio and video components of the media. This can be specified instead of the above two properties. If this is specified along with one or the other of the above properties, this will be used for the one that isn't specified.

If bits per second values are not specified for video and/or audio, the default adopted for video is 2.5Mbps, while the audio default is adaptive, depending upon the sample rate and the number of channels.
