capDlgVideoDisplay
The capDlgVideoDisplay macro displays a dialog box in which the user can set or adjust the video
output. This dialog box might contain controls that affect the hue, contrast, and
brightness of the displayed image, as well as key color alignment. You can use
this macro or explicitly send the WM_CAP_DLG_VIDEODISPLAY message.
BOOL capDlgVideoDisplay(
Parameters
hwnd
Handle of a capture window.
Return Values
Returns TRUE if successful or FALSE otherwise.
Remarks
The controls in this dialog box do not affect digitized video data; they
affect only the output or redisplay of the video signal.
The Video Display dialog box is unique for each capture driver. Some capture
drivers might not support a Video Display dialog box. Applications can determine
if the capture driver supports this message by checking the fHasDlgVideoDisplay member of the CAPDRIVERCAPS structure.
