isVideoAutoplayAllowed

Whether a video may start itself.

Defaults to true — the historical behaviour, where a shape carrying props.playing starts as soon as it is on screen. An app that sets options.allowVideoAutoplay: false gets the opposite: no video ever starts on its own, and one only plays once someone presses play in its controls. The shape's playing prop is left alone either way, so the setting is a property of this editor rather than an edit to the document.
