capDlgVideoSource
The capDlgVideoSource macro 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 use this macro or
explicitly send the WM_CAP_DLG_VIDEOSOURCE message.
BOOL capDlgVideoSource(
Parameters
hwnd
Handle of a capture window.
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.
