A Boolean attribute; if specified, the video will automatically begin buffering even if it's not set to automatically play.
A Boolean attribute; if specified, the video will automatically begin buffering even if it's not set to automatically play. This should be used for cases in which it is considered likely that the video will be played (for example, if the user navigated to the page specifically to play the video, not if there happens to be a video embedded along with other content). The video is buffered until the media cache is full.
Implementation note: though part of the early drafts of the HTML5 specification, the
autobuffer attribute has been removed in later releases. It has been removed from Gecko 2.0 and other browsers, and never implemented in some. The spec defines a new enumerated attribute,
preload, to replace the
autobuffer attribute, with a different syntax.
