====== SGI O2 Webcam ====== {{:rb:sgianim.gif?direct |}} The SGI O2 workstation has a multimedia card option, fitted in the right hand side rear slot. Two versions of these are available, * An audio only card which is of no use for a webcam as there is no video interface. * An audio and video capture capture card. {{rb:sgi_o2_cam.jpg?200 |}} The combined audio and video card is required for the webcam. It supports video input via the analogue input on a phono connector, or the O2 camera via the SGI specific interface. This looks like a SCSI-3 connector but only supports the the O2 camera. The camera is not particularly good image quality, but good enough for a simple webcam. I have not tried the webcam capture scripts with a video (phono) input. I believe there is a FireWire PCI card option available, but it is not cheap. To produce a working webcam, there are several steps the capture script has to perform:- * Set the camera parameters, chiefly the shutter speed. * Take the picture. * Upload it to a web server.
