* XvImageSink renders video frames to a drawable (XWindow) on a local display
* using the XVideo extension. Rendering to a remote display is theoretically
* possible but i doubt that the XVideo extension is actually available when
* connecting to a remote display. This element can receive a Window ID from the
* application through the #GstVideoOverlay interface and will then render
* video frames in this drawable. If no Window ID was provided by the
* application, the element will create its own internal window and render
* into it.

* <title>Events</title>
* <para>
* XvImageSink creates a thread to handle events coming from the drawable. There
* are several kind of events that can be grouped in 2 big categories: input
* events and window state related events. Input events will be translated to
* navigation events and pushed upstream for other elements to react on them.
* This includes events such as pointer moves, key press/release, clicks etc...
* Other events are used to handle the drawable appearance even when the data
* is not flowing (GST_STATE_PAUSED). That means that even when the element is
* paused, it will receive expose events from the drawable and draw the latest
* frame with correct borders/aspect-ratio.

Original commit message from CVS: 2004-01-23 Julien MOUTTE <julien@moutte.net> * gst-libs/gst/play/gstplay.c: (gst_play_pipeline_setup), (gst_play_set_location), (gst_play_seek_to_time), (gst_play_set_audio_sink), (gst_play_set_visualization), (gst_play_connect_visualization), (gst_play_get_sink_element): Reworked the pipeline from scratch. Visualization is back and switch went out as i realized it was not possible to use the way i wanted. * sys/ximage/ximagesink.c: (gst_ximagesink_imagepool_clear), (gst_ximagesink_change_state), (gst_ximagesink_dispose): Move xcontext clearing in state change from READY to NULL. So that one can clean the X ressources keeping the element. * sys/xvimage/xvimagesink.c: (gst_xvimagesink_xcontext_get), (gst_xvimagesink_imagepool_clear), (gst_xvimagesink_change_state), (gst_xvimagesink_colorbalance_set_value), (gst_xvimagesink_colorbalance_get_value), (gst_xvimagesink_set_property), (gst_xvimagesink_dispose), (gst_xvimagesink_init): Same xcontext cleaning than ximagesink in state change from READY to NULL and fixed some stupid bugs in colorbalance get/set values. Also added the following feature : when nobody tries to set some values to the colorbalance levels before the xcontext is grabbed, then when creating channels list from Xv attributes we set the internal values to the Xv defaults. This way we handle buggy Xv drivers that set default hue values far from the middle of the range (Thanks to Jon Trowbridge for pointing that issue). * sys/xvimage/xvimagesink.h: Adding a cb_changed boolean to know if colorbalance levels have been set before xcontext is grabbed.
