VideoDecoder: dequeue event
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.
Note: This feature is available in Dedicated Web Workers.
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.
Syntax
Use the event name in methods like addEventListener(), or set an event handler property.
js
addEventListener("dequeue", (event) => {});
ondequeue = (event) => {};
Example
js
videoDecoder.addEventListener("dequeue", (event) => {
// Queue up more encoding work
});
