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!

sys/v4l/v4lsrc_calls.*: Remove sync-related stuff. Original commit message from CVS: 2005-07-07 Andy Wingo <wingo@pobox.com> * sys/v4l/v4lsrc_calls.h: * sys/v4l/v4lsrc_calls.c: Remove sync-related stuff. (gst_v4lsrc_get_fps_list): Moved here from gstv4lsrc.c. (gst_v4lsrc_buffer_new): Totally derive from GstBuffer. * sys/v4l/v4l_calls.h: Cast to V4lElement. * sys/v4l/v4l_calls.c: Header loc fixen, don't load mjpeg, all v4lelements are sources. * sys/v4l/gstv4lxoverlay.h: * sys/v4l/gstv4lxoverlay.c: * sys/v4l/gstv4ltuner.h: * sys/v4l/gstv4ltuner.c: Header loc fixen. * sys/v4l/gstv4lsrc.h: * sys/v4l/gstv4lsrc.c: Crucial GPL update. Clean up a bit, port to PushSrc/BaseSrc. Removed most sync-related properties, videorate or something should handle that. Made a live source. * sys/v4l/gstv4lelement.h: * sys/v4l/gstv4lelement.c: Derive from GstPushSrc. No more signals. Some cleanups. * sys/v4l/gstv4lcolorbalance.h: Interface header update. * sys/v4l/gstv4l.c: Don't register v4lelement, or the jpeg/mjpeg stuff. * sys/v4l/Makefile.am: Build everything except the jpeg/mjpeg stuff. * sys/Makefile.am (SUBDIRS): Hit the V4L crack pipe.

sys/v4l/gstv4lelement.c (gst_v4lelement_start) Original commit message from CVS: 2005-08-24 Andy Wingo <wingo@pobox.com> * sys/v4l/gstv4lelement.c (gst_v4lelement_start) (gst_v4lelement_stop): Call _start and _stop for xoverlay instead of _open and _close. * sys/v4l/gstv4lxoverlay.h: * sys/v4l/gstv4lxoverlay.c (gst_v4l_xoverlay_set_xwindow_id): Open an Xv connection here, instead of all the time. Make Xv only be loaded if you axe for it. Kindof a workaround for buggy behaviour of Xv when using remote xservers (XvQueryExtension would block). (gst_v4l_xoverlay_stop, gst_v4l_xoverlay_start): New functions, replace the _open and _close public API. Only start the xv connection if necessary. (gst_v4l_xoverlay_open, gst_v4l_xoverlay_close): Made static.
