- * 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>
