action : list([And(numeric,nonnegative),string]):= [] ; A list of lists. Each entry is a list containing a nonnegative time position and a string of Maple Notation Action code which will execute when the player reaches that position.

defaultdimensions : truefalse:=true ; Indicates whether the default player dimensions should be used.

height : posint:=400 ; The height in pixels of the component, which is not used if the default dimensions are enabled.

hidecontrols : truefalse:=false ; Indicates whether the player controls are hidden.

identity : {name,string}; The reference name of the component.

loop : truefalse:=false ; Indicates whether the playback stops upon reaching the stopping time, or loops back to the starting time.

showcontrols : truefalse:=true ; Indicates whether the player controls are shown when the mouse pointer hovers over the component.

startindex : nonnegint:=0 ; The starting time, representing seconds.

stopindex : nonnegint:=0 ; The stopping time, representing seconds.

width : posint:=600 ; The width in pixels of the component, which is not used if the default dimensions are enabled.

The VideoPlayer command in the Component Constructors package returns an XML function call which represents a VideoPlayer Component.

The generated XML may be used with the results of commands in the Layout Constructors package to create an entire Worksheet or Document in XML form. Such a representation of a Worksheet or Document may be inserted into the current document using the InsertContent command.
