Abstract
A system and process for making live digital video feeds simultaneously available to multiple applications running on a computing device. This involves using a live image server that maintains a camera directory file containing the names of available feeds, and the name and location of an image file for each feed. The image file includes image data corresponding to a current frame of the feed and an index indicative of a frame sequence number. Each time a new frame becomes available, image data representing the frame is put into its associated image file, in place of previously stored image data. A client application chooses a feed from the camera directory file, then accesses the associated image file and makes a copy of the image data. When the client wants a new frame, it determines if the image file index has changed. If so, the client copies the new image data.
