preload
A DOMString value that gives a hint to the browser how much of the media should be fetched when the webpage is loaded.
Declaration
attribute DOMString preload;Discussion
Possible values are auto, metadata, and none. The attribute defaults to auto, suggesting to the browser the server is able to provide the media for immediate and agressive downloading. The metadata value suggests minimal server interaction to retrieve only metadata and the first frames of the media resource, while none suggests no server interaction is needed. These preload values can be changed dynamically. There is no guarantee that you get the behavior that you request.
