VideoWrapper_VidCap Details

The VideoWrapper_VidCap API adapter allows VideoWrapper to support cameras driven by the VidCapture API.

The VidCapture SDK is required to build the VideoWrapper_VidCap source and the run-times are required by the VideoWrapper_VidCap binaries. Please visit http://sourceforge.net/projects/vidcapture/ to download.

Supported Operating Systems

• Windows NT/2000/XP

Camera Initialization String

The initialization string for VIDEO_openVideo() takes the following form:

"vc: camNum width frameRate colorMode scale outputMode"

where

• vc is the identifier for the VideoWrapper_VidCap library.
• camNum is a number (starting at 0) representing the camera to open.
• size is the desired width (e.g., 640), or widthxheight (e.g., 640x480). Any width is ok, and if no height is provided, a 4:3 aspect is assumed
• frameRate is the desired frame rate
• colorMode is a string. Specifies the format of the desired mode. Either the exact match (e.g., RGB32, Y411, YUYV, etc) or one of yuv (for any yuv color mode) or rgb (for any color rgb mode) is allowed. Case insensitive.
• scale is 0 or 1. 1 means a mode of 2x or 4x the size can be used, and scaled to the correct size.

Camera Properties Supported

The getting and setting of camera properties are not currently implemented.

Functions Not Supported

The VideoWrapper_VidCap API adapter does not implement the following functions:

• VIDEO_showPropertiesDialog()
