capCaptureSequence macro

使用　capCaptureSequence macro　可以將視訊擷取視窗中的視訊與音訊內容儲存成一個 AVI 檔案, 檔案名稱則可以是透過 capFileSetCaptureFile macro 事先設定, 若沒有設定檔案名稱, 則內定為 C:\CAPTURE.AVI。

The capCaptureSequence macro initiates streaming video and audio capture to a file. You can use this macro or explicitly send the WM_CAP_SEQUENCE message.

BOOL capCaptureSequence(
hwnd
);


Parameters

hwnd

Handle of a capture window.

Return Values

Returns TRUE if successful or FALSE otherwise.
If an error occurs and an error callback function is set using the capSetCallbackOnError macro, the error callback function is called.

Remarks

If you want to alter the parameters controlling streaming capture, use the capCaptureSetSetup macro 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 macros:

capSetCallbackOnError
capSetCallbackOnStatus
capSetCallbackOnVideoStream
capSetCallbackOnWaveStream
capSetCallbackOnYield
