WM_CAP_DLG_VIDEOFORMAT
The WM_CAP_DLG_VIDEOFORMAT message displays a dialog box in which the user can
select the video format. The Video Format dialog box might be used to select
image dimensions, bit depth, and hardware compression options. You can send this
message explicitly or by using the capDlgVideoFormat macro.
WM_CAP_DLG_VIDEOFORMAT
wParam = (WPARAM) 0;
lParam = 0L;
Return Values
Returns TRUE if successful or FALSE otherwise.
Remarks
After this message returns, applications might need to update the CAPSTATUS structure because the user might have changed the image dimensions.
The Video Format dialog box is unique for each capture driver. Some capture
drivers might not support a Video Format dialog box. Applications can determine
if the capture driver supports this message by checking the fHasDlgVideoFormat member of CAPDRIVERCAPS.
