Restricting buffer size in HTML5 video for an MP4 file

Can the HTML5 Video tag be utilized to load an MP4 file while managing the amount of data downloaded/buffered from the server (assuming byte ranges are supported)?

In essence, I would like to specify "only download 60 seconds ahead" in order to prevent the browser from downloading a full 2 GB file when the user is likely to leave before watching the entire video.

Answer №1

Origin:

To inform the browser about which part of the media to play, you can utilize the media-fragment syntax in the URL.

document.querySelector("button").onclick = ({target}) => {
  target.remove();
  document.querySelector("video").play();
};
video { max-height: 100vh; }
<button>play</button>
<video muted src="https://upload.wikimedia.org/wikipedia/commons/2/22/Volcano_Lava_Sample.webm#t=0,60"></video>

Answer №2

Response: Browsers are designed to buffer only the necessary data, rather than downloading an entire file. There is no need to manually adjust buffering from a customized HTML5 player perspective.
