The capSetVideoFormat macro sets the format of captured video data. You can use this macro or explicitly call the WM_CAP_SET_VIDEOFORMAT message.
BOOL capSetVideoFormat(
hwnd,
psVideoFormat,
wSize
);
Returns TRUE if successful or FALSE otherwise.
Because video formats are device-specific, applications should check the return value from this function to determine if the format is accepted by the driver.
Windows NT: Requires version 3.1 or later.
Windows: Requires Windows 95 or later.
Windows CE: Unsupported.
Header: Declared in vfw.h.
