HTMLVideoElement

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.

Properties

Inherits properties from its ancestor interfaces, HTMLMediaElement, and HTMLElement.

HTMLVideoElement.height: Is a DOMString that reflects the height HTML attribute, which specifies the height of the display area, in CSS pixels.
HTMLVideoElement.poster: Is a DOMString 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 long containing the intrinsic height of the resource in CSS pixels, taking into account the dimensions, aspect ratio, clean aperture, resolution, and so forth, as defined for the format used by the resource. If the element's ready state is HAVE_NOTHING, the value is 0.
HTMLVideoElement.videoWidth Read only: Returns an unsigned long containing the intrinsic width of the resource in CSS pixels, taking into account the dimensions, aspect ratio, clean aperture, resolution, and so forth, as defined for the format used by the resource. If the element's ready state is HAVE_NOTHING, the value is 0.
HTMLVideoElement.width: Is a DOMString that reflects the width HTML attribute, which specifies the width of the display area, in CSS pixels.

HTMLVideoElement.mozDecodedFrames Read only: Returns an unsigned long with the count of parsed video frames that have been decoded into images.
HTMLVideoElement.mozPresentedFrames Read only: Returns an unsigned long with the count of decoded frames that have been presented to the rendering pipeline for painting.
HTMLVideoElement.mozPaintedFrames Read only: Returns an unsigned long with the count of presented frames which were painted on the screen.
HTMLVideoElement.mozFrameDelay Read only: Returns an double with the time which the last painted video frame was late by, in seconds.
