+/**
+ * SECTION:gstcamerasrc
+ * @short_description: Base class for camera sources
+ *
+ * <refsect2>
+ * camerasrc is a generic base class for video source elements.
+ * </refsect2>
+ * <refsect2>
+ * <title>Capturing modes</title>
+ * <para>
+ * GstCameraSrc provides three different operating modes: VIEWFINDER, IMAGE and
+ * VIDEO capturing. This mode is selected by using "capture-mode" property.
+ * Viewfinder mode is used for capturing preview frames before performing the
+ * high-quality image capture, or before starting video recording. Image and
+ * video modes should be switched just before starting the corresponding
+ * action. GstCameraSrc itself doesn't make any difference between these modes,
+ * and this setting is mainly targeted for subclasses (see below).
+ * </para>
+ * </refsect2>
+ * <refsect2>
+ * <title>Image capture</title>
+ * <para>
+ * In order to capture and image of higher quality than negotiated in element's
+ * source pad, #GstPhotography's prepare_for_capture() must be called. It
+ * Takes a #GstCaps object as a parameter. These caps will define the desired
+ * high-quality capture resolution. However, this resolution is just a
+ * suggestion; GstCameraSrc uses the given #GstPhotoCapturePrepared callback
+ * to inform the selected capturing resolution back to the application. During
+ * this callback application also has responsibility to adjust image pipeline
+ * capsfilters according to this resolution. After HQ image is captured and
+ * pushed, GstCameraSrc switches automatically back to old viewfinder resolution.
+ * </para>
+ * </refsect2>
+ * <refsect2>
+ * <title>Video capture</title>
+ * <para>
+ * By default GstCameraSrc works just like v4l2src, so it can be used for normal
+ * video stream capturing as well. There is no separate GstPhotography API
+ * function for starting video capturing (in contrary to image capturing), but
+ * the notification is just given by setting the #GstCameraSrc:capture-mode
+ * to video.
+ * </para>
+ * </refsect2>
+ * <refsect2>
+ * <title>Messages</title>
+ * <para>
+ * During capturing process GstCameraSrc sends a bunch of GstMessages to bus:
+ * <itemizedlist>
+ * <listitem>
+ * <para>
+ * GST_PHOTOGRAPHY_AUTOFOCUS_DONE is sent when application has started
+ * autofocus operation and it finishes. This message contains following fields:
+ * "status" is an integer which contains GstFocusStatus enumeration value.
+ * It tells whether the focusing succeeded or failed.
+ * "focus-window-rows" and "focus-window-columns" are integers and they tell
+ * the focus matrix size.
+ * "focus-windows" is a GArray containing a list of integers. They define
+ * window numbers where the focus is. Window numbering starts from one, which
+ * is top-left window, increasing from left-to-right, top-to-bottom order. This
+ * field is only valid when focusing status is SUCCESS.
+ * "focus-window-coverage" field is an integer and it tells the percentage how
+ * big area from wiewfinder window was used for autofocusing.
+ * </para>
+ * </listitem>
+ * <listitem>
+ * <para>
+ * GST_PHOTOGRAPHY_SHAKE_RISK is sent during autofocusing process. It keeps
+ * application updated about the possible risk for shaken image. Sending of
+ * this message is done in subclasses, so it is implementation-specific and
+ * may not be always sent.
+ * </para>
+ * </listitem>
+ * <listitem>
+ * <para>
+ * "photo-capture-start" is sent just before the actual high-quality capture
+ * operation is about to happen.
+ * </para>
+ * </listitem>
+ * <listitem>
+ * <para>
+ * "photo-capture-end" is sent immediately after high-quality image has been
+ * captured. This can be used for example for playing the shutter sound
+ * in sync with the capture operation.
+ * </para>
+ * </listitem>
+ * <listitem>
+ * <para>
+ * "caf-update" messages are sent when camera subsystem supports continuous
+ * autofocusing (CAF). The message contains information about CAF status. It
+ * has one G_TYPE_INT field called "status" and its content is one of the
+ * values defined in GstPhotography API's GstFocusStatus enumeration.
+ * </para>
+ * </listitem>
+ * </itemizedlist>
+ * </para>
+ * </refsect2>
+ * <refsect2>
+ * <title>Supported formats</title>
+ * <para>
+ * Currently GstCameraSrc only supports UYVY and YUY2 color formats.
+ * </para>
+ * </refsect2>
+ * <refsect2>
+ * <title>Subclasses</title>
+ * <para>
+ * Hardware-specific imaging functionalities are implemented in subclasses.
+ * GstCameraSrc provides vmethods for this purpose. Subclasses tasks are to
+ * are handle e.g. autofocusing, flash, image capturing,
+ * post-processing and all other non-V4L2 standard operations. Subclass
+ * can also implement the API only partially; by default GstCameraSrc uses dummy
+ * functions for all vmethods that are not implemented by the subclass.
+ * </para>
