The capSetVideoFormat macro sets the format of captured video data. You can use this macro or explicitly call the WM_CAP_SET_VIDEOFORMAT message.

  hwnd,           
  psVideoFormat,  
  wSize           
);
 

Parameters

hwnd

Handle of a capture window.

psVideoFormat

Address of a BITMAPINFO structure.

wSize

Size, in bytes, of the structure referenced by s.
