/**
* SECTION:element-xvimagesink
*
* <refsect2>
* <para>
* XvImageSink renders video frames to a drawable (XWindow) on a local display
* using the XVideo extension. Rendering to a remote display is theorically
* 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 XOverlay 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.
* </para>
* <title>Scaling</title>
* <para>
* The XVideo extension, when it's available, handles hardware accelerated
* scaling of video frames. This means that the element will just accept
* incoming video frames no matter their geometry and will then put them to the
* drawable scaling them on the fly. Using the
* <link linkend="GstXvImageSink--force-aspect-ratio">force-aspect-ratio</link>
* property it is possible to enforce scaling with a constant aspect ratio,
* which means drawing black borders around the video frame.
* </para>
* <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.
* </para>
* <title>Pixel aspect ratio</title>
* <para>
* When changing state to GST_STATE_READY, XvImageSink will open a connection to
* the display specified in the
* <link linkend="GstXvImageSink--display">display</link> property or the
* default display if nothing specified. Once this connection is open it will
* inspect the display configuration including the physical display geometry and
* then calculate the pixel aspect ratio. When receiving video frames with a
* different pixel aspect ratio, XvImageSink will use hardware scaling to
* display the video frames correctly on display's pixel aspect ratio.
* Sometimes the calculated pixel aspect ratio can be wrong, it is
* then possible to enforce a specific pixel aspect ratio using the
* <link linkend="GstXvImageSink--pixel-aspect-ratio">pixel-aspect-ratio</link>
* property.
* </para>
* <title>Examples</title>
* <para>
* Here is a simple pipeline to test hardware scaling :
* <programlisting>
* gst-launch -v videotestsrc ! xvimagesink
* </programlisting>
* When the test video signal appears you can resize the window and see that
* video frames are scaled through hardware (no extra CPU cost). You can try
* again setting the force-aspect-ratio property to true and observe the borders
* drawn around the scaled image respecting aspect ratio.
* <programlisting>
* gst-launch -v videotestsrc ! xvimagesink force-aspect-ratio=true
* </programlisting>
* </para>
* <para>
* Here is a simple pipeline to test navigation events :
* <programlisting>
* gst-launch -v videotestsrc ! navigationtest ! xvimagesink
* </programlisting>
* While moving the mouse pointer over the test signal you will see a black box
* following the mouse pointer. If you press the mouse button somewhere on the
* video and release it somewhere else a green box will appear where you pressed
* the button and a red one where you released it. (The navigationtest element
* is part of gst-plugins-good.) You can observe here that even if the images
* are scaled through hardware the pointer coordinates are converted back to the
* original video frame geometry so that the box can be drawn to the correct
* position. This also handles borders correctly, limiting coordinates to the
* image area
* </para>
* <para>
* Here is a simple pipeline to test pixel aspect ratio :
* <programlisting>
* gst-launch -v videotestsrc ! video/x-raw-yuv, pixel-aspect-ratio=(fraction)4/3 ! xvimagesink
* </programlisting>
* This is faking a 4/3 pixel aspect ratio caps on video frames produced by
* videotestsrc, in most cases the pixel aspect ratio of the display will be
* 1/1. This means that XvImageSink will have to do the scaling to convert
* incoming frames to a size that will match the display pixel aspect ratio
* (from 320x240 to 320x180 in this case). Note that you might have to escape
* some characters for your shell like '\(fraction\)'.
* </para>
* <para>
* Here is a test pipeline to test the colorbalance interface :
* <programlisting>
* gst-launch -v videotestsrc ! xvimagesink hue=100 saturation=-100 brightness=100
* </programlisting>
* </para>
* </refsect2>

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.

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.
