The dequeue event of the VideoDecoder interface fires to signal a decrease in VideoDecoder.decodeQueueSize.
This eliminates the need for developers to use a setTimeout() poll to determine when the queue has decreased, and more work should be queued up.
Use the event name in methods like addEventListener(), or set an event handler property.
addEventListener("dequeue", (event) => { })
ondequeue = (event) => { }
videoDecoder.addEventListener("dequeue", (event) => {
// Queue up more encoding work
});
