You can retrieve the current value of the user-initiated capture flag by using the WM_CAP_GET_SEQUENCE_SETUP message (or the capCaptureGetSetup macro). The value of the flag is stored in the fMakeUserHitOKToCapture member of the CAPTUREPARMS structure. You can provide the user with precise control over when to start a capture session by setting this member to TRUE. AVICap displays a dialog box after allocating all video and audio buffers for a capture session. This lets the user eliminate capture delays because of software initialization. If your application uses a small number of video buffers, this dialog box is probably unnecessary. The default value is FALSE.
