-/**
- * 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" tells whether the focusing succeeded or failed.
- * "focus_window_rows" and "focus_window_columns" tell the focus matrix size.
- * "focus_window_mask" is an integer containing a bitmask. It contains
- * rows x columns bits, which mark the focus points in the focus matrix.
- * Lowest bit (LSB) always represents the top-left corner of the focus matrix.
- * This field is only valid when focusing status is SUCCESS.
- * </para>
- * </listitem>
- * <listitem>
- * <para>
- * GST_PHOTOGRAPHY_SHAKE_RISK is sent during autofocusing process. It keeps
- * application updated about the possible risk for shaken image.
- * </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 it may contain following values:
- * 0 - IDLE, 1 - RUNNING, 2 - SUCCESS, 3 - FAILURE.
- * </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>
