WM_CAP_FILE_SET_INFOCHUNK
The
WM_CAP_FILE_SET_INFOCHUNK message sets and clears information chunks.
Information chunks can be inserted in an AVI file during capture to embed text
strings or custom data. You can send this message explicitly or by using the capFileSetInfoChunk macro.
WM_CAP_FILE_SET_INFOCHUNK
wParam = (WPARAM)0;
lParam = (LPARAM) (LPCAPINFOCHUNK) (lpInfoChunk);
Parameters
lpInfoChunk
Address of a CAPINFOCHUNK structure defining the
information chunk to be created or deleted.
Return Values
Returns TRUE
if successful or FALSE otherwise.
If an error
occurs and an error callback function is set using the WM_CAP_SET_CALLBACK_ERROR message, the error callback
function is called.
Remarks
Multiple
registered information chunks can be added to an AVI file. After an information
chunk is set, it continues to be added to subsequent capture files until either
the entry is cleared or all information chunk entries are cleared. To clear a
single entry, specify the information chunk in the fccInfoID member and
NULL in the lpData member of the CAPINFOCHUNK structure. To clear
all entries, specify NULL in fccInfoID.
