SGSetVideoDigitizerComponent

The SGSetVideoDigitizerComponent function allows the sequence grabber component to assign a video digitizer component to your video channel.

pascal ComponentResult SGSetVideoDigitizerComponent 
                           (SGChannel c, ComponentInstance vdig);

c

Identifies the channel connection for this operation.

vdig

Contains a component instance that identifies a connection to a video digitizer component. Your video channel component should use this video digitizer component to obtain its source video data.

DESCRIPTION

Typically, your video channel component locates its own video digitizer component. The sequence grabber component calls the SGSetVideoDigitizerComponent function if an application chooses to assign a video digitizer to a video channel.
