The source code is small and relatively simple to modif, and it can run in headless mode. Note though that for many of the webcams, the gspca driver does not have good support for controlling brightness or contrast, which basically means that outdoor pictures tend to come coimpletely white. With the cheap camcorders under $200 (and they have better resolution, optics, zoom), one wonders whether it is worth the trouble of going through USB... Of course it works a lot better for us europeans with the Euro vs USD exchange rate, and firweire-equipped camcorders sell for less than Euro 150 including tax :) > julian > _______________________________________________ > freebsd-multimedia@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-multimedia > To unsubscribe, send any mail to > "freebsd-multimedia-unsubscribe@freebsd.org"
