Tag Minimization

The start-tag is required for this element. The end-tag is optional, if your SGML declaration allows minimization.

Description

This element points to an external entity containing video data.

Processing expectations

May be formatted inline or as a displayed block, depending on context. Rendering a video is usually accomplished by reserving a rectangular area on the display and "running" the video in that frame.

There are two ways to provide content for VideoData: EntityRef or FileRef. It is best to use only one of these methods. However, if multiple sources are provided, EntityRef will be used in favor of FileRef.

Parents

These elements contain VideoData: VideoObject.

Children

In some contexts, the following elements are allowed anywhere: BeginPage, IndexTerm.

Attributes

Align

Align specifies the horizontal alignment of the image data on the page or within the element that frames it.

Depth

Depth specifies the desired depth (vertical distance, at least in horizontal writing systems) of the video data.

EntityRef

EntityRef identifies the general entity which points to the content of the video data.

FileRef

FileRef specifies the name of the file which contains the content of the video data.

Format

Format identifies the format of the video data. The Format must be a defined notation.

Scale

Scale specifies integer representing a percentage scaling factor (retaining the relative dimensions of the original video frame). If unspecified, the value 100 (100%) is assumed.

Scalefit

If ScaleFit has the value 1 (true), then the video frame is to be scaled (uniformly) to the specified width or depth. The default value of 0 (false) indicates that the image will not be scaled to fit (although it may still be scaled by the Scale attribute).

SrcCredit

SrcCredit contains details about the source of the video data.

Width

Width indicates the width of the graphic.
