VideoTrackGenerator: writable property

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The writable property of the VideoTrackGenerator interface returns a WritableStream. This allows the writing of VideoFrames to the VideoTrackGenerator.track.
