- * gst-launch -v filesrc location=input.xyz ! giosink location=file:///home/joe/out.xyz

- * The above pipeline will simply copy a local file. Instead of giosink,

- * Another example pipeline:
- * <programlisting>
- * gst-launch -v filesrc location=foo.mp3 ! mad ! flacenc ! giosink location=smb://othercomputer/foo.flac
- * </programlisting>
- * The above pipeline will re-encode an mp3 file into FLAC format and store

- * <programlisting>
- * gst-launch -v audiotestsrc num-buffers=100 ! vorbisenc ! oggmux ! giosink location=file:///home/foo/bar.ogg

- *
- * <refsect2>
- * <para>
- * This plugin writes incoming data to a local or remote location specified

- * Example pipeline:
- * <programlisting>
- * gst-launch -v filesrc location=input.xyz ! gnomevfssink location=file:///home/joe/out.xyz
- * </programlisting>
- * The above pipeline will simply copy a local file. Instead of gnomevfssink,
- * we could just as well have used the filesink element here.
- * </para>
- * <para>
- * Another example pipeline:
- * <programlisting>
- * gst-launch -v filesrc location=foo.mp3 ! mad ! flacenc ! gnomevfssink location=smb://othercomputer/foo.flac
- * </programlisting>
- * The above pipeline will re-encode an mp3 file into FLAC format and store
- * it on a remote host using the Samba protocol.
- * </para>
- * <para>
- * Applications can connect to the allow-overwrite signal to receive a callback when an
- * existing file will be overwritten. The return value of the signal will determine if
- * gnomevfssink will overwrite the resource or abort with an error.

- * SECTION:element-gnomevfssrc
- * @short_description: Read from any GnomeVFS-supported location
- * @see_also: #GstFileSrc, #GstGnomeVFSSink
- *
- * <refsect2>
- * <para>
- * This plugin reads data from a local or remote location specified
- * by an URI. This location can be specified using any protocol supported by
- * the GnomeVFS library. Common protocols are 'file', 'http', 'ftp', or 'smb'.
- * </para>
- * <para>
- * In case the element-gnomevfssrc::iradio-mode property is set and the
- * location is a http resource, gnomevfssrc will send special icecast http
- * headers to the server to request additional icecast metainformation. If
- * the server is not an icecast server, it will display the same behaviour
- * as if the element-gnomevfssrc::iradio-mode property was not set. However,
- * if the server is in fact an icecast server, gnomevfssrc will output
- * data with a media type of application/x-icy, in which case you will
- * need to use the #ICYDemux element as follow-up element to extract
- * the icecast meta data and to determine the underlying media type.
- * </para>

- *
- * gather queue: 5 4
- * decode queue: 6 7 8 9
- *
- * Copy head of the gather queue (5) to decode queue. This is a keyframe so we
- * can start decoding.
- *
- * gather queue: 4
- * decode queue: 5 6 7 8 9
- *
- * Decode frames in decode queue, store raw decoded data in output queue, we
- * can take the head of the decode queue and prepend the decoded result in the
- * output queue:
- *
- * gather queue: 4
- * decode queue:
- * output queue: 9 8 7 6 5
- *
- * Now output all the frames in the output queue, picking a frame from the
- * head of the queue.
- *
- * Copy head of the gather queue (4) to decode queue, we flushed the gather
- * queue and can now store input buffer in the gather queue:
- *
- * gather queue: 1
- * decode queue: 4
- *
- * When we receive EOS, the queue looks like:
- *
- * gather queue: 3 2 1
- * decode queue: 4
- *
- * Fill decode queue, first keyframe we copy is 2:
- *
- * gather queue: 1
- * decode queue: 2 3 4
- *
- * Decoded output:
- *
- * gather queue: 1
- * decode queue:
- * output queue: 4 3 2

- * multiple of 16 pixels in both X and Y direction. It is however perfectly
- * possible to encode images with other dimensions because an arbitrary
- * rectangular cropping region can be set up. This element will automatically
- * set up a correct cropping region if the dimensions are not multiples of 16
- * pixels. The "border" and "center" properties control how this cropping
- * region will be set up.
- * </para>
- * <para>
- * To control the quality of the encoding, the "bitrate" and "quality"
- * properties can be used. These two properties are mutualy exclusive. Setting
- * the bitrate property will produce a constant bitrate (CBR) stream while
- * setting the quality property will produce a variable bitrate (VBR) stream.
- * </para>
- * <title>Example pipeline</title>
- * <programlisting>
- * gst-launch -v videotestsrc num-buffers=1000 ! theoraenc ! oggmux ! filesink location=videotestsrc.ogg
- * </programlisting>
- * This example pipeline will encode a test video source to theora muxed in an
- * ogg container. Refer to the theoradec documentation to decode the create
- * stream.

-/**
- * SECTION:element-theoraparse
- * @short_description: parses theora streams
- * @see_also: theoradec, oggdemux, vorbisparse
- *
- * <refsect2>
- * <para>
- * The theoraparse element will parse the header packets of the Theora
- * stream and put them as the streamheader in the caps. This is used in the
- * multifdsink case where you want to stream live theora streams to multiple
- * clients, each client has to receive the streamheaders first before they can
- * consume the theora packets.
- * </para>
- * <para>
- * This element also makes sure that the buffers that it pushes out are properly
- * timestamped and that their offset and offset_end are set. The buffers that
- * vorbisparse outputs have all of the metadata that oggmux expects to receive,
- * which allows you to (for example) remux an ogg/theora file.
- * </para>
- * <para>
- * In addition, this element allows you to fix badly synchronized streams. You
- * pass in an array of (granule time, buffer time) synchronization points via
- * the synchronization-points GValueArray property, and this element will adjust
- * the granulepos values that it outputs. The adjustment will be made by
- * offsetting all buffers that it outputs by a specified amount, and updating
- * that offset from the value array whenever a keyframe is processed.
- * </para>
- * <title>Example pipelines</title>
- * <para>
- * <programlisting>
- * gst-launch -v filesrc location=video.ogg ! oggdemux ! theoraparse ! fakesink
- * </programlisting>
- * This pipeline shows that the streamheader is set in the caps, and that each
- * buffer has the timestamp, duration, offset, and offset_end set.
- * </para>
- * <para>
- * <programlisting>
- * gst-launch filesrc location=video.ogg ! oggdemux ! vorbisparse \
- * ! oggmux ! filesink location=video-remuxed.ogg
- * </programlisting>
- * This pipeline shows remuxing. video-remuxed.ogg might not be exactly the same
- * as video.ogg, but they should produce exactly the same decoded data.
- * </para>
- * </refsect2>

- * Then we accumulate more buffers:

- * @short_description: parses vorbis streams
- * @see_also: vorbisdec, oggdemux, theoraparse
- *
- * <refsect2>
- * <para>
- * The vorbisparse element will parse the header packets of the Vorbis
- * stream and put them as the streamheader in the caps. This is used in the
- * multifdsink case where you want to stream live vorbis streams to multiple
- * clients, each client has to receive the streamheaders first before they can
- * consume the vorbis packets.
- * </para>
- * <para>
- * This element also makes sure that the buffers that it pushes out are properly
- * timestamped and that their offset and offset_end are set. The buffers that
- * vorbisparse outputs have all of the metadata that oggmux expects to receive,
- * which allows you to (for example) remux an ogg/vorbis file.
- * </para>
- * <title>Example pipelines</title>
- * <para>
- * <programlisting>
- * gst-launch -v filesrc location=sine.ogg ! oggdemux ! vorbisparse ! fakesink
- * </programlisting>
- * This pipeline shows that the streamheader is set in the caps, and that each
- * buffer has the timestamp, duration, offset, and offset_end set.
- * </para>
- * <para>
- * <programlisting>
- * gst-launch filesrc location=sine.ogg ! oggdemux ! vorbisparse \
- * ! oggmux ! filesink location=sine-remuxed.ogg
- * </programlisting>
- * This pipeline shows remuxing. sine-remuxed.ogg might not be exactly the same
- * as sine.ogg, but they should produce exactly the same decoded data.

- * @see_also: #oggdemux, #oggmux, #vorbisparse, #GstTagSetter
- * @short_description: retags vorbis streams
- *
- * <refsect2>
- * <para>
- * The vorbistags element can change the tag contained within a raw
- * vorbis stream. Specifically, it modifies the comments header packet
- * of the vorbis stream.
- * </para>
- * <para>
- * The element will also process the stream as the #vorbisparse element does
- * so it can be used when remuxing an Ogg Vorbis stream, without additional
- * elements.
- * </para>
- * <para>
- * Applications can set the tags to write using the #GstTagSetter interface.
- * Tags contained withing the vorbis bitstream will be picked up
- * automatically (and merged according to the merge mode set via the tag
- * setter interface).
- * </para>
- * <title>Example pipelines</title>
- * <para>
- * This element is not useful with gst-launch, because it does not support
- * setting the tags on a #GstTagSetter interface. Conceptually, the element
- * will usually be used like:
- * <programlisting>
- * gst-launch -v filesrc location=foo.ogg ! oggdemux ! vorbistag ! oggmux ! filesink location=bar.ogg
- * </programlisting>

- * property, calculate the geometry of desired video frames and then check that
- * the peer pad accept those new caps. If it does it will then allocate a buffer
- * in video memory with this new geometry and return it with the new caps.
- * </para>
- * <title>Events</title>
- * <para>
- * XImageSink 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, XImageSink will open a connection to
- * the display specified in the
- * <link linkend="GstXImageSink--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 caps negotiation will occur, the
- * video sink will set the calculated pixel aspect ratio on the caps to make
- * sure that incoming video frames will have the correct pixel aspect ratio for
- * this display. Sometimes the calculated pixel aspect ratio can be wrong, it is
- * then possible to enforce a specific pixel aspect ratio using the
- * <link linkend="GstXImageSink--pixel-aspect-ratio">pixel-aspect-ratio</link>
- * property.
- * </para>
- * <title>Examples</title>
- * <para>
- * Here is a simple pipeline to test reverse negotiation :
- * <programlisting>
- * gst-launch -v videotestsrc ! queue ! ximagesink
- * </programlisting>
- * When the test video signal appears you can resize the window and see that
- * scaled buffers of the desired size are going to arrive with a short delay.
- * This illustrates how buffers of desired size are allocated along the way.
- * If you take away the queue, scaling will happen almost immediately.
- * </para>
- * <para>
- * Here is a simple pipeline to test navigation events :
- * <programlisting>
- * gst-launch -v videotestsrc ! navigationtest ! ffmpegcolorspace ! ximagesink
- * </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.)
- * </para>
- * <para>
- * Here is a simple pipeline to test pixel aspect ratio :
- * <programlisting>
- * gst-launch -v videotestsrc ! video/x-raw-rgb, pixel-aspect-ratio=(fraction)4/3 ! videoscale ! ximagesink
- * </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 videoscale 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>

-/**
- * 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>

- * SECTION:gstcamerabin
- * @short_description: camera capture bin
- *
- * <refsect2>
- * <para>
- * 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.
- * </para>
- * <informalfigure>
- * <mediaobject>
- * <imageobject><imagedata fileref="camerabin.png"/></imageobject>
- * <textobject><phrase>CameraBin structure</phrase></textobject>

- * </programlisting>
- * </para>
- * </refsect2>
- * <refsect2>
- * <title>Image capture</title>
- * <para>
- * Taking still images is initiated with the #GstCameraBin::user-start action
- * signal. Once the image has captured, #GstCameraBin::img-done signal is fired.
- * It allows to decide wheter to take another picture (burst capture, bracketing
- * shot) or stop capturing. The last captured image is shown
- * until one switches back to view finder using #GstCameraBin::user-stop action
- * signal.
- * </para>
- * <para>
- * Available resolutions can be taken from the #GstCameraBin:inputcaps property.
- * Image capture resolution can be set with #GstCameraBin::user-image-res
- * action signal.
- * </para>
- * </refsect2>
- * <refsect2>
- * <title>Video capture</title>
- * <para>
- * Video capture is started with the #GstCameraBin::user-start action signal too.
- * In addition to image capture one can use #GstCameraBin::user-pause to
- * pause recording and #GstCameraBin::user-stop to end recording.
- * </para>
- * <para>
- * Available resolutions and fps can be taken from the #GstCameraBin:inputcaps
- * property. #GstCameraBin::user-res-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>Photography interface</title>
- * <para>
- * GstCameraBin implements gst photography interface, which can be used to set
- * and get different settings related to digital imaging. Since currently many
- * of these settings require low-level support the photography interface support
- * is dependent on video src element. In practice photography interface settings
- * cannot be used successfully until in PAUSED state when the video src has
- * opened the video device.
- * </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.
- * </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>
