The LEAD Video Image Overlay filter is a DirectShow transform filter that enables overlaying images on a video stream. The filter has a single video input which must be connected in order for the filter to work.
Each instance of the filter supports three layers: Video, Overlay image, and a solid background color. The three supported layers can be ordered as needed. Supported layers can be customized through a set of properties that include a mask image, transparency, and positioning.
The dimensions of the output stream match the input video stream. The overlay image layer does not contribute to the output dimensions.
The filter exposes its functionality through both user and programming interfaces.
You must unlock the LEAD Video Image Overlay Filter in order to use it. For more information, refer to Evaluation Mechanism Overview.
