Ah, now I see. For medical applications you might want to be a little more picky about the board you use. bt848/bt878 are often used in consumer grade products. Don't get me wrong -- these chips work great -- but I wouldn't stake anyone's life on that. As for the API, I think you'll find V4L provides basic initialization of the board and capture to memory. Any image processing, disk or network I/O, timing or synchronization -- all that is pretty much up to you. n --== Sent via Deja.com http://www.deja.com/ ==-- Before you buy.
