libbgrab & webcam

libbgrab is a video4linux grabbing library to facilitate use of framegrabber cards and webcams through a few function calls. To implement constant throughput and to avoid frame loss delays, triple buffering is used through local buffer copying in a separate grabbing thread. The many demo and utility programs included can display live video to X, convert live video to ASCII, smoothly zoom live-video (using Glide), do some image processing (using MMX), and provide a stand-alone webcam image server.
