Methods

(private, static) getVideoElement_() → (non-null) {HTMLVideoElement}

For some of this polyfill's implementation, we need to query a video element. But for some embedded systems, it is memory-expensive to create multiple video elements. Therefore, we check the document to see if we can borrow one to query before we fall back to creating one temporarily.
