Video Capture Settings

The CAPTUREPARMS structure contains the control parameters for streaming video capture. This structure controls several aspects of the capture process, and allows you to perform the following tasks:

• specify the frame rate.
• specify the number of allocated video buffers.
• disable and enable audio capture.
• specify the time interval for the capture.
• specify whether an MCI device (VCR or videodisc) is used during capture.
• specify keyboard or mouse control for ending streaming.
• specify the type of video averaging applied during capture.

You can retrieve the current capture settings within the CAPTUREPARMS structure by sending the WM_CAP_GET_SEQUENCE_SETUP message (or the capCaptureGetSetup macro) to a capture window. You can set one or more current capture settings by updating the appropriate members of the CAPTUREPARMS structure and then sending the WM_CAP_SET_SEQUENCE_SETUP message (or the capCaptureSetSetup macro) and CAPTUREPARMS to a capture window.
