Request for position on MediaRecorder constant bitrate audio encoding
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: w3c/mediacapture-record#185 <https://github.com/w3c/mediacapture-record/pull/185> - Explainer: https://docs.google.com/document/d/10OheBob6lP7v-fO89g0A5F9BYnsMEU5Nkh4p-Bk0... - 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. Thanks, Simon
Hi Simon, I think CBR for MediaRecorder is fine. It also got consensus within the WebRTC WG. Le ven. 31 juil. 2020 à 10:53, Simon Jackson <simon.jackson@sonocent.com> a écrit :

Great, thanks! I will update the Chrome status with a positive signal for webkit. Thanks again, Simon On Mon, 3 Aug 2020 at 21:55, youenn fablet <youennf@gmail.com> wrote:
