Hello WebKit-dev,

I'd like to ask for Webkit's official position on a change to the
editors draft of the mediacapture-record specification to make it
possible to request either constant or variable bitrate audio encoding
from the MediaRecorder.

   - Specification: https://w3c.github.io/mediacapture-record/#mediarecorder-api
   - Pull request & discussion of additions:
   - Explainer:
   - Chromestatus entry: https://chromestatus.com/feature/5730124735447040

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.
