WM_CAP_SEQUENCE
The
WM_CAP_SEQUENCE message initiates streaming video and audio capture to a file.
You can send this message explicitly or by using the capCaptureSequence macro.
WM_CAP_SEQUENCE
wParam = (WPARAM) 0;
lParam = 0L;
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
If you want
to alter the parameters controlling streaming capture, use the WM_CAP_SET_SEQUENCE_SETUP message prior to starting the capture.
By default,
the capture window does not allow other applications to continue running during
capture. To override this, either set the fYield member of the CAPTUREPARMS structure to TRUE, or
install a yield callback function.
During
streaming capture, the capture window can optionally issue notifications to
your application of specific types of conditions. To install callback
procedures for these notifications, use the following messages:
WM_CAP_SET_CALLBACK_ERROR
WM_CAP_SET_CALLBACK_STATUS
WM_CAP_SET_CALLBACK_YIELD
WM_CAP_SET_CALLBACK_VIDEOSTREAM
WM_CAP_SET_CALLBACK_WAVESTREAM
