Overlay Mixer 2 Filter

The Overlay Mixer 2 filter is identical to the Overlay Mixer filter, except:

• It supports only VIDEOINFOHEADER2 formats.
• It has a higher merit, which enables it to be added to a filter graph automatically.

The Overlay Mixer 2 is provided so that the Filter Graph Manager will add it to the graph when it renders non-DVD MPEG-2 video. The choice of whether to use the Overlay Mixer or the Overlay Mixer 2 is handled by the component that builds the graph, either the Filter Graph Manager, the Capture Graph Builder, or the DVD Graph Builder. From an application perspective, they are the same filter, with the same interfaces and functionality.

The following table contains information specific to the Overlay Mixer 2. For all other filter data, refer to the documentation for the Overlay Mixer.
