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.
