> A new enumeration (BitrateMode) has been added for specifying either constant or variable bitrate for audio encoding, MediaRecorderOptions has an extra field called audioBitrateMode for requesting a specific bitrate mode from the MediaRecorder and a field was added to MediaRecorder for retrieving the bitrate mode being used for encoding.
