-= Cleanups =
-* often two g_object_set for same object one after the other
-* use GST_*_OBJECT () more often
-* there are two gst_element_set_state() one after each other
-
-= Renaming =
-* internal use of img->image, vid->video
-
-= Refactorisation =
-* gstcamerabin:gst_camerabin_rewrite_tags
- - sounds fishy, should use normal tagsetter method
- - gst_camerabin_rewrite_tags_to_bin(9 why don't we just send a tag-event?
-
-* file-name property
- - supplying an already opened filedeskriptor would be more safe
- - need to check what filesink does if the file exists and cannot be overwritten
-
-* imagbin
- - we want async operation here (especialy for burst mode capture)
- - right now, its a bit fragile as we muck with locked_state
- - main problem is that the location for filesink can only be set in NULL/READY
- and we need to do that sync'ed with the dataflow. we can't use multifilesink
- as it does a file per pad_push
- - one problem of the current approach is that we can't have an image in e.g,
- postprocessing while anotherone is beeing saved
- - we could use a pool of imagebins:
- - configure one (set filename)
- - push_buffer
- - on eos, put it back to the pool
- - for this we need to check that we can have multiple instances of e.g.
- dsp jpeg encoders

-/**
- * SECTION:element-camerabin
- *
- * GstCameraBin is a high-level camera object that encapsulates the gstreamer
- * internals and provides a task based API for the application. It consists of
- * three main data paths: view-finder, image capture and video capture.
- *
- * <informalfigure>
- * <mediaobject>
- * <imageobject><imagedata fileref="camerabin.png"/></imageobject>
- * <textobject><phrase>CameraBin structure</phrase></textobject>
- * <caption><para>Structural decomposition of CameraBin object.</para></caption>
- * </mediaobject>
- * </informalfigure>
- *
- * <refsect2>
- * <title>Example launch line</title>
- * |[
- * gst-launch -v -m camerabin
- * ]|
- * </refsect2>
- * <refsect2>
- * <title>Image capture</title>
- * <para>
- * Image capture is selected by switching #GstCameraBin:mode to %MODE_IMAGE.
- * Taking still images is initiated with the #GstCameraBin::capture-start action
- * signal. Once the image has been captured, "image-captured" gst message is
- * posted to the bus and capturing another image is possible. If application
- * has set #GstCameraBin:preview-caps property, then a "preview-image" gst
- * message is posted to bus containing preview image formatted according to
- * specified caps. Eventually when image has been saved
- * #GstCameraBin::image-done signal is emitted.
- *
- * Available resolutions can be taken from the #GstCameraBin:video-source-caps
- * property. Image capture resolution can be set with
- * #GstCameraBin::set-image-resolution action signal.
- *
- * Some video source elements implement the #GstPhotography interface, which contains
- * functions and properties for setting photography parameters. One can use
- * gst_bin_iterate_all_by_interface() to get a reference to it.
- *
- * </para>
- * </refsect2>
- * <refsect2>
- * <title>Video capture</title>
- * <para>
- * Video capture is selected by switching #GstCameraBin:mode to %MODE_VIDEO.
- * The capture is started with the #GstCameraBin::capture-start action signal
- * too. In addition to image capture one can use #GstCameraBin::capture-pause to
- * pause recording and #GstCameraBin::capture-stop to end recording.
- *
- * Available resolutions and fps can be taken from the
- * #GstCameraBin:video-source-caps property.
- * #GstCameraBin::set-video-resolution-fps action signal can be used to set
- * frame rate and resolution for the video recording and view finder as well.
- * </para>
- * </refsect2>
- * <refsect2>
- * <title>States</title>
- * <para>
- * Elements within GstCameraBin are created and destroyed when switching
- * between NULL and READY states. Therefore element properties should be set
- * in NULL state. User set elements are not unreffed until GstCameraBin is
- * unreffed or replaced by a new user set element. Initially only elements
- * needed for view finder mode are created to speed up startup. Image bin and
- * video bin elements are created when setting the mode or starting capture.
- * GstCameraBin must be in the PLAYING state before #GstCameraBin::capture-start
- * is called.
- * </para>
- * </refsect2>
- * <refsect2>
- * <title>Video and image previews</title>
- * <para>
- * GstCameraBin contains #GstCameraBin:preview-caps property, which is used to
- * determine whether the application wants a preview image of the captured
- * picture or video. When set, a GstMessage named "preview-image" will be sent.
- * This message will contain a GstBuffer holding the preview image, converted
- * to a format defined by those preview caps. The ownership of the preview
- * image is kept in GstCameraBin, so application should ref the preview buffer
- * object if it needs to use it elsewhere than in message handler.
- *
- * Defining preview caps is done by selecting the capturing #GstCameraBin:mode
- * first and then setting the property. Camerabin remembers caps separately for
- * both modes, so it is not necessary to set the caps again after changing the
- * mode.
- * </para>
- * </refsect2>
- * <refsect2>
- * <note>
- * <para>
- * Since the muxers tested so far have problems with discontinous buffers, QoS
- * has been disabled, and then in order to record video, you MUST ensure that
- * there is enough CPU to encode the video. Thus choose smart resolution and
- * frames per second values. It is also highly recommended to avoid color
- * conversions; make sure all the elements involved work with the same
- * colorspace (i.e. rgb or yuv i420 or whatelse).
- * </para>
- * </note>
- * </refsect2>

- * @start_time: running time at which to start the new segment, or -1 to

- *
- * Switch to a new feed. The segment opened by the previously active pad, if
- * any, will be closed, and a new segment opened before data flows again.
- *
- * This signal must be emitted when the element has been blocked via the <link
- * linkend="GstInputSelector-block">block</link> signal.
- *
- * If you have a stream with only one switch element, such as an audio-only
- * stream, a stream switch should be performed by first emitting the block
- * signal, and then emitting the switch signal with -1 for the stop and start
- * time values.
- *
- * The intention of the @stop_time and @start_time arguments is to allow
- * multiple switch elements to switch and maintain stream synchronization.
- * When switching a stream with multiple feeds, you will need as many switch
- * elements as you have feeds. For example, a feed with audio and video will
- * have one switch element between the audio feeds and one for video.
- *
- * A switch over multiple switch elements should be performed as follows:
- * First, emit the <link linkend="GstInputSelector-block">block</link>
- * signal, collecting the returned values. The maximum running time returned
- * by block should then be used as the time at which to close the previous
- * segment.
- *
- * Then, query the running times of the new audio and video pads that you will
- * switch to. Naturally, these pads are on separate switch elements. Take the
- * minimum running time for those streams and use it for the time at which to
- * open the new segment.
- *
- * If @pad is the same as the current active pad, the element will cancel any
- * previous block without adjusting segments.
- *
- * <note><simpara>
- * the signal changed from accepting the pad name to the pad object.
