For v4l: partly. The v4l API missed some important options for the DC10+ card which required the original author to extend the v4l API a bit with driver-specific ioctl()s. For some purposes, the v4l API still applies (e.g. channel/input switching, video-watching), but for (compressed) capturing, it works differently. There is already software that does this (mjpegtools' lavrec and gstreamer's v4lmjpegsrc plugin). Documentation about the special API can be found in the documentation in the DC10+ driver package. For v4l2, we're aiming at staying 100% to the original v4l2 API and so far, it seems like we'll succeed, so v4l2 should make your life a lot easier. Unfortunately, the driver for v4l2 isn't ready yet, but we're working on it ;-).
