The writable property of the MediaStreamTrackGenerator interface returns a WritableStream. This allows the writing of media frames to the MediaStreamTrackGenerator. The frames will be audio or video. The type is dictated by the kind of MediaStreamTrackGenerator that was created.



In the following example video frames are transformed then written to the WritableStream accessed with MediaStreamTrackGenerator.writable.

const trackProcessor = new MediaStreamTrackProcessor({ track: videoTrack });
const trackGenerator = new MediaStreamTrackGenerator({ kind: 'video' });
