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

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.
