uvcdynctrl binary package in Ubuntu Mantic ppc64el

 This package provides the tools needed to add vendor specific
 controls to uvc devices.
 .
 uvcdynctrl is part of the Webcam Library.
 .
 The Webcam Library libwebcam is designed to simplify
 the development of webcam applications, primarily on Linux but
 with an option to be ported to other platforms, in particular
 Solaris. It realizes part of what the unwritten Video4Linux user
 space library was always supposed to be: an easy to use library
 that shields its users from many of the difficulties and problems
 of using the V4L2 API directly.
