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.
WM_CAP_DLG_VIDEOSOURCE
wParam = (WPARAM) 0;
lParam = 0L;
Return Values
Returns TRUE if successful or FALSE otherwise.
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.
