The video annotation object (ANNOBJECT_VIDEO) is a rectangle containing a scaled image that can be activated to play an AVI file or capture a multimedia file. With the automated functions, in design mode, the user clicks and drags to specify the rectangle in the current window. A dialog box then lets the user specify the preferred options. In run mode, clicking on the icon plays the AVI file.
For playing the video, you must have DirectX installed.
To capture an AVI file from a video card, LTCAP15u.dll is required.
With low-level functions, you must define the size and position of the rectangle. Other applicable properties have the following defaults, which you can change:
