Your choices: 1. BSD Brooktree 848 (See bktr(4) and meteor(4)) This is *BSD-specific video capture API. So far only Brooktree (Conexant) 848/878 chip is supported by *BSD. Thus, actually this API is BT848/878-specific. 2. Video for Linux 1/2 (See http://v4l2spec.bytesex.org/) These are the video capture APIs for Linux. There are two versions: V4L and V4L2. Supported hardware list: http://linux.bytesex.org/v4l2/drivers.html (V4L2 mainly) http://mxhaard.free.fr/spca5xx.html (V4L) MPlayer supports both kinds of API's. But to gain Linux binary compatibility for FreeBSD, V4L/V4L2 must be introduced to FreeBSD. ------------------------------------------------------------------------ From Beijing, China
