Some interface implementations for video4linux/video4linux2 plugins: a Tuner interface, with which one can select inp... Original commit message from CVS: Some interface implementations for video4linux/video4linux2 plugins: * a Tuner interface, with which one can select inputs and stations. Audio work is underway here, but unfinished. * A Xoverlay interface with which one can do simple overlay. Similar to the API of the v4l/Xv XFree86 extension. Widget implementation for GTK-2.0 coming up in the sandbox. * Colorbalance - for adapting colors (brightness, contrast, etc.) - pretty basic and maybe somewhat overdesigned. But it'll do for now. Apart from these interfaces, there's also a loadable library 'xwindowlistener' that listenes to X for the movement of a window and the overlap of other windows. This is partly copied from xawtv (and thus partly GPL :(), but it's needed for the xoverlay interface implementation in the v4l/v4l2 elements. Lastly, some small changes to remove redundant properties from the v4l/v4l2 elements since these can be done much simpler. Comments appreciated!

Audio work is underway here, but unfinished. * A Xoverlay interface with which one can do simple overlay. Similar to the API of the v4l/Xv XFree86 extension. Widget implementation for GTK-2.0 coming up in the sandbox. * Colorbalance - for adapting colors (brightness, contrast, etc.) - pretty basic and maybe somewhat overdesigned. But it'll do for now. Apart from these interfaces, there's also a loadable library 'xwindowlistener' that listenes to X for the movement of a window and the overlap of other windows. This is partly copied from xawtv (and thus partly GPL :(), but it's needed for the xoverlay interface implementation in the v4l/v4l2 elements. Lastly, some small changes to remove redundant properties from the v4l/v4l2 elements since these can be done much simpler. Comments appreciated!
