WM_CAP_DLG_VIDEOSOURCE

The WM_CAP_DLG_VIDEOSOURCE message displays a dialog box in which the user can control the video source. The Video Source dialog box might contain controls that select input sources; alter the hue, contrast, brightness of the image; and modify the video quality before digitizing the images into the frame buffer. You can send this message explicitly or by using the capDlgVideoSource macro.

Remarks

The Video Source dialog box is unique for each capture driver. Some capture drivers might not support a Video Source dialog box. Applications can determine if the capture driver supports this message by checking the fHasDlgVideoSource member of the CAPDRIVERCAPS structure.
