It would be nice to have one (but not so broken by > design as V4L). I'm open to suggestions.... In a past life, I messed about with MMOS/2 (OS/2's multimedia subsystem) but that doesn't qualify me for such a task. As to how such a thing be implemented - does it sound reasonable to create a CAM-like abstraction of which all the video devices may be connected to? It would be great to have something in place which is not so device specific. > ATC>I'm messing about writing a KLD for a OV511 based USB capture device and > ATC>it would be nice if there was some generic interface for all such > ATC>devices.

One is a "Black Widow" branded ISA board (which I have some DOS source code to drive it) and the other is a PCI board with a "Zoran" chip on it. -- Antony T Curtis BSc Unix Analyst Programmer http://homepage.ntlworld.com/antony.t.curtis/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-arch" in the body of the message
