Implemented by the <video> element, the HTMLVideoElement interface provides special properties and methods for manipulating video objects. It also inherits properties and methods of HTMLMediaElement and HTMLElement.

The list of supported media formats varies from one browser to the other. You should either provide your video in a single format that all the relevant browsers supports, or provide multiple video sources in enough different formats that all the browsers you need to support are covered.

Instance properties

HTMLVideoElement.poster

A string that reflects the poster HTML attribute, which specifies an image to show while no video data is available.

HTMLVideoElement.videoHeight Read only

Returns an unsigned integer value indicating the intrinsic height of the resource in CSS pixels, or 0 if no media is available yet.

HTMLVideoElement.videoWidth Read only

Returns an unsigned integer value indicating the intrinsic width of the resource in CSS pixels, or 0 if no media is available yet.

Firefox-specific properties

HTMLVideoElement.mozParsedFrames Read only

Instance methods

Inherits methods from its parent interface, HTMLMediaElement, and HTMLElement.

HTMLVideoElement.cancelVideoFrameCallback()
