Now I just need to switch from -stable to -current (I'm very unhappy about the stability of -stable anyways, so that's no loss). > c) meteor interface. > I have meteor cards too, and I quite like the common interface.

It's not that the drivers share some of the interface in itself that is the problem, but when there is stuff like "compatibility modes" in the bktr driver, something is wrong. I have plenty of trouble with the bktr driver, and I can't (don't want to) look at such code to figure things out. V4L2 does at least seem better to me than anything else out there. -- Frode Vatvedt Fjeld To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-multimedia" in the body of the message
