{{APIRef("Media Source Extensions")}}{{AvailableInWorkers("window_and_dedicated")}}
The endstreaming event of the {{domxref("ManagedMediaSource")}} interface is fired when the {{domxref("ManagedMediaSource.streaming", "streaming")}} property changes from true to false. This indicates that the user agent has enough data buffered to ensure uninterrupted playback, and the application can stop fetching new media segments.
Use the event name in methods like {{domxref("EventTarget.addEventListener", "addEventListener()")}}, or set an event handler property.
addEventListener("endstreaming", (event) => {});
onendstreaming = (event) => {};
A generic {{domxref("Event")}}.
This example creates a {{domxref("ManagedMediaSource")}}, attaches it to a {{htmlelement("video")}} element, and uses the startstreaming and endstreaming events to control when media segments are fetched.
const videoUrl =
"https://mdn.github.io/shared-assets/videos/flower-fragmented.mp4";
const mediaType = 'video/mp4; codecs="avc1.64001F, mp4a.40.2"';
if (ManagedMediaSource.isTypeSupported(mediaType)) {
const video = document.createElement("video");
const source = new ManagedMediaSource();
video.controls = true;
video.disableRemotePlayback = true;
video.src = URL.createObjectURL(source);
document.body.appendChild(video);
let shouldFetch = false;
source.addEventListener("sourceopen", () => {
const sourceBuffer = source.addSourceBuffer(mediaType);
source.addEventListener("startstreaming", async () => {
console.log("startstreaming — fetching media data");
shouldFetch = true;
const response = await fetch(videoUrl);
const data = await response.arrayBuffer();
if (shouldFetch) {
sourceBuffer.appendBuffer(data);
}
});
source.addEventListener("endstreaming", () => {
console.log("endstreaming — enough data buffered");
shouldFetch = false;
});
});
}
