- *
- * <refsect2>
- * <para>
- * This plugin writes incoming data to a local or remote location specified
- * by an URI. This location can be specified using any protocol supported by
- * the GIO library or it's VFS backends. Common protocols are 'file', 'ftp',
- * or 'smb'.
- * </para>
- * <para>
- * Example pipeline:
- * <programlisting>
- * gst-launch -v filesrc location=input.xyz ! giosink location=file:///home/joe/out.xyz
- * </programlisting>
- * The above pipeline will simply copy a local file. Instead of giosink,
- * 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 ! giosink 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>
- * Another example pipeline:
- * <programlisting>
- * gst-launch -v audiotestsrc num-buffers=100 ! vorbisenc ! oggmux ! giosink location=file:///home/foo/bar.ogg
- * </programlisting>
- * The above pipeline will encode a 440Hz sine wave to Ogg Vorbis and stores
- * it in the home directory of user foo.

- * data read. Instead of giosrc, we could just as well have used the

- * Another example pipeline:
- * <programlisting>
- * gst-launch -v giosrc location=smb://othercomputer/foo.xyz ! filesink location=/home/joe/foo.xyz
- * </programlisting>
- * The above pipeline will copy a file from a remote host to the local file

- * Yet another example pipeline:
- * <programlisting>
- * gst-launch -v giosrc location=http://music.foobar.com/demo.mp3 ! mad ! audioconvert ! audioresample ! alsasink

- *
- * <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>
- * <para>
- * Example pipeline:
- * <programlisting>
- * gst-launch -v gnomevfssrc location=file:///home/joe/foo.xyz ! fakesink
- * </programlisting>
- * The above pipeline will simply read a local file and do nothing with the
- * data read. Instead of gnomevfssrc, we could just as well have used the
- * filesrc element here.
- * </para>
- * <para>
- * Another example pipeline:
- * <programlisting>
- * gst-launch -v gnomevfssrc location=smb://othercomputer/foo.xyz ! filesink location=/home/joe/foo.xyz
- * </programlisting>
- * The above pipeline will copy a file from a remote host to the local file
- * system using the Samba protocol.
- * </para>
- * <para>
- * Yet another example pipeline:
- * <programlisting>
- * gst-launch -v gnomevfssrc location=http://music.foobar.com/demo.mp3 ! mad ! audioconvert ! audioresample ! alsasink
- * </programlisting>
- * The above pipeline will read and decode and play an mp3 file from a
- * web server using the http protocol.
- * </para>

- * Discont flag: D D D
- *
- * - Each Discont marks a discont in the decoding order.
- * - The keyframes mark where we can start decoding.
- *
- * First we prepend incomming buffers to the gather queue, whenever we receive

- *
- * The above data will be accumulated in the gather queue like this:
- *
- * gather queue: 9 8 7
- * D
- *
- * Whe buffer 4 is received (with a DISCONT), we flush the gather queue like
- * this:
- *
- * while (gather)
- * take head of queue and prepend to decode queue.
- * if we copied a keyframe, decode the decode queue.
- *

- * decode queue: 7 8 9
- *
- * After we received 5 (Keyframe) and 6:
- *
- * gather queue: 6 5 4
- * decode queue: 7 8 9
- *
- * When we receive 1 (DISCONT) which triggers a flush of the gather queue:
- *
- * Copy head of the gather queue (6) to decode queue:
- *
- * 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
- *
- * Leftover buffer 1 cannot be decoded and must be discarded.

- * This element encodes raw video into a Theora stream.
- * <ulink url="http://www.theora.org/">Theora</ulink> is a royalty-free
- * video codec maintained by the <ulink url="http://www.xiph.org/">Xiph.org
- * Foundation</ulink>, based on the VP3 codec.
- * </para>
- * <para>
- * The theora codec internally only supports encoding of images that are a
- * 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.

-/**
- * 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>

- * for vorbis, each buffer is a keyframe when we have the previous

- *
- * gather queue:
- * decode queue: 7 8 9

- * Then we decode each buffer in the decode queue in order and put the output

- * yields:
- *
- * gather queue:
- * decode queue: 7 8 9
- * output queue: 9 8
- *
- * Then we remove the consumed buffers from the decode queue. Buffer 7 is not
- * completely consumed, we need to keep it around for when we receive buffer
- * 6. This yields:
- *
- * gather queue:
- * decode queue: 7
- * output queue: 9 8
- *
- * Then we accumulate more buffers:
- *
- * gather queue: 6 5 4
- * decode queue: 7
- * output queue:
- *
- * prepending to the decode queue on DISCONT yields:
- *
- * gather queue:

-/**
- * SECTION:element-vorbisparse
- * @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.
- * </para>

- * SECTION:element-vorbistag
- * @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>
- * </para>

+- audio base classes:
+ - GstBaseAudioSink
+ - parse caps into rinbuffer spec, also make sure surround sound
+ is parsed correctly.
+ - implement seek/query/convert
+ - implement getrange scheduling
+ - simple resampling
+ - more accurate master/slave calibration handling
+ - faster audio cutoff when going to PAUSED
+ - resubmit samples from ringbuffer when doing PAUSED->PLAYING again
+ - the ringbuffer should have a state where it is filling up the

+The RTP libraries
+---------------------
+
+ RTP Buffers
+ -----------
+ The real time protocol as described in RFC 3550 requires the use of special
+ packets containing an additional RTP header of at least 12 bytes. GStreamer
+ provides some helper functions for creating and parsing these RTP headers.
+ The result is a normal #GstBuffer with an additional RTP header.
+
+ RTP buffers are usually created with gst_rtp_buffer_new_allocate() or
+ gst_rtp_buffer_new_allocate_len(). These functions create buffers with a
+ preallocated space of memory. It will also ensure that enough memory
+ is allocated for the RTP header. The first function is used when the payload
+ size is known. gst_rtp_buffer_new_allocate_len() should be used when the size
+ of the whole RTP buffer (RTP header + payload) is known.
+
+ When receiving RTP buffers from a network, gst_rtp_buffer_new_take_data()
+ should be used when the user would like to parse that RTP packet. (TODO Ask
+ Wim what the real purpose of this function is as it seems to simply create a
+ duplicate GstBuffer with the same data as the previous one). The
+ function will create a new RTP buffer with the given data as the whole RTP
+ packet. Alternatively, gst_rtp_buffer_new_copy_data() can be used if the user
+ wishes to make a copy of the data before using it in the new RTP buffer. An
+ important function is gst_rtp_buffer_validate() that is used to verify that
+ the buffer a well formed RTP buffer.
+
+ It is now possible to use all the gst_rtp_buffer_get_*() or
+ gst_rtp_buffer_set_*() functions to read or write the different parts of the
+ RTP header such as the payload type, the sequence number or the RTP
+ timestamp. The use can also retreive a pointer to the actual RTP payload data
+ using the gst_rtp_buffer_get_payload() function.
+
+ RTP Base Payloader Class (GstBaseRTPPayload)
+ --------------------------------------------
+
+ All RTP payloader elements (audio or video) should derive from this class.
+
+ RTP Base Audio Payloader Class (GstBaseRTPAudioPayload)
+ -------------------------------------------------------
+
+ This base class can be tested through it's children classes. Here is an
+ example using the iLBC payloader (frame based).
+
+ For 20ms mode :
+
+ GST_DEBUG="basertpaudiopayload:5" gst-launch-0.10 fakesrc sizetype=2
+ sizemax=114 datarate=1900 ! audio/x-iLBC, mode=20 ! rtpilbcpay
+ max-ptime="40000000" ! fakesink
+
+ For 30ms mode :
+
+ GST_DEBUG="basertpaudiopayload:5" gst-launch-0.10 fakesrc sizetype=2
+ sizemax=150 datarate=1662 ! audio/x-iLBC, mode=30 ! rtpilbcpay
+ max-ptime="60000000" ! fakesink
+
+ Here is an example using the uLaw payloader (sample based).
+
+ GST_DEBUG="basertpaudiopayload:5" gst-launch-0.10 fakesrc sizetype=2
+ sizemax=150 datarate=8000 ! audio/x-mulaw ! rtppcmupay max-ptime="6000000" !
+ fakesink
+
+ RTP Base Depayloader Class (GstBaseRTPDepayload)
+ ------------------------------------------------
+
+ All RTP depayloader elements (audio or video) should derive from this class.

+ *
+ * In GStreamer, image tags are #GstBuffer<!-- -->s containing the raw image
+ * data, with the buffer caps describing the content type of the image
+ * (e.g. image/jpeg, image/png, text/uri-list). The buffer caps may contain
+ * an additional 'image-type' field of #GST_TYPE_TAG_IMAGE_TYPE to describe
+ * the type of image (front cover, back cover etc.). #GST_TAG_PREVIEW_IMAGE
+ * tags should not carry an image type, their type is already indicated via

+ *
+ * This function will do various checks and typefind the encoded image

+/*
+ The design goals of this code are:
+ - Very fast algorithm
+ - SIMD-friendly algorithm
+ - Low memory requirement
+ - Good *perceptual* quality (and not best SNR)
+
+ Warning: This resampler is relatively new. Although I think I got rid of
+ all the major bugs and I don't expect the API to change anymore, there
+ may be something I've missed. So use with caution.
+
+ This algorithm is based on this original resampling algorithm:
+ Smith, Julius O. Digital Audio Resampling Home Page
+ Center for Computer Research in Music and Acoustics (CCRMA),
+ Stanford University, 2007.
+ Web published at http://www-ccrma.stanford.edu/~jos/resample/.
+
+ There is one main difference, though. This resampler uses cubic
+ interpolation instead of linear interpolation in the above paper. This
+ makes the table much smaller and makes it possible to compute that table
+ on a per-stream basis. In turn, being able to tweak the table for each
+ stream makes it possible to both reduce complexity on simple ratios
+ (e.g. 2/3), and get rid of the rounding operations in the inner loop.
+ The latter both reduces CPU time and makes the algorithm more SIMD-friendly.

+/*
+ The design goals of this code are:
+ - Very fast algorithm
+ - SIMD-friendly algorithm
+ - Low memory requirement
+ - Good *perceptual* quality (and not best SNR)
+
+ Warning: This resampler is relatively new. Although I think I got rid of
+ all the major bugs and I don't expect the API to change anymore, there
+ may be something I've missed. So use with caution.
+
+ This algorithm is based on this original resampling algorithm:
+ Smith, Julius O. Digital Audio Resampling Home Page
+ Center for Computer Research in Music and Acoustics (CCRMA),
+ Stanford University, 2007.
+ Web published at http://www-ccrma.stanford.edu/~jos/resample/.
+
+ There is one main difference, though. This resampler uses cubic
+ interpolation instead of linear interpolation in the above paper. This
+ makes the table much smaller and makes it possible to compute that table
+ on a per-stream basis. In turn, being able to tweak the table for each
+ stream makes it possible to both reduce complexity on simple ratios
+ (e.g. 2/3), and get rid of the rounding operations in the inner loop.
+ The latter both reduces CPU time and makes the algorithm more SIMD-friendly.

+/*
+ The design goals of this code are:
+ - Very fast algorithm
+ - SIMD-friendly algorithm
+ - Low memory requirement
+ - Good *perceptual* quality (and not best SNR)
+
+ Warning: This resampler is relatively new. Although I think I got rid of
+ all the major bugs and I don't expect the API to change anymore, there
+ may be something I've missed. So use with caution.
+
+ This algorithm is based on this original resampling algorithm:
+ Smith, Julius O. Digital Audio Resampling Home Page
+ Center for Computer Research in Music and Acoustics (CCRMA),
+ Stanford University, 2007.
+ Web published at http://www-ccrma.stanford.edu/~jos/resample/.
+
+ There is one main difference, though. This resampler uses cubic
+ interpolation instead of linear interpolation in the above paper. This
+ makes the table much smaller and makes it possible to compute that table
+ on a per-stream basis. In turn, being able to tweak the table for each
+ stream makes it possible to both reduce complexity on simple ratios
+ (e.g. 2/3), and get rid of the rounding operations in the inner loop.
+ The latter both reduces CPU time and makes the algorithm more SIMD-friendly.

+decodebin:
+
+ A bin with a sinkpad that decodes the data into raw formats. It works by sending
+ the input data through a typefind element and then recursively autoplugs elements
+ from the registry until a raw format is obtained. It will then create a new ghostpad
+ on itself to signal the app of the new pad.
+
+ Decodebin will also remove pads when they are removed from the stream.
+
+ TODO
+ - reuse of decoderbin, cleanup in READY state
+ - threading after demuxing?
+ - new_media events should be handled.
+ - caching of elements.
+ - abstract more elements, pads (typefind, ...);
+
+ The autoplugging happens as follows:
+
+ 1) typefind is added internally to the bin.
+ 2) the have_type signal is connected to typefind.
+ 3) in the have_type callback the close_pad_link function is called
+ 4) close_pad_link checks the type on the pad, if it is raw, a ghostpad
+ is created and autoplugging for that pad stops.
+ 5) if the type of the pad is not raw, a list of possible elements that
+ can connect to this type is generated in find_compatibles.
+ 6) try_to_link_1 with the element list is called. The function will loop
+ over the element list and will try to connect one of the elements to
+ the pad. If the link works, a call is made to close_link.
+ 7) close_link loops over all the source pads of the element and
+ recursively calls 4) for any ALWAYS pad. For elements with
+ a SOMETIMES pad, a structure is set up and is passed to the callback
+ of the new_pad signal.
+ 8) in the new_pad callback, 4) is called to try to autoplug the
+ new pad.
+
+
+playbasebin:
+
+ A bin with an uri property. It will find the right source element from the registry
+ and connect a decoderbin to it. When going to the PAUSED state, it will iterate the
+ decoderbin and listen for new pad signals from it. It will connect a queue to each
+ new pad and will iterate the decoderbin until one of the queues is filled. It is
+ assumed that by that time all the streams will be found so that when leaving the
+ PAUSED state, one can query the number of streams in the media file with the given
+ uri.
+
+ Playbasebin internally groups related streams together in a GstPlayBaseGroup. This
+ is particulary important for chained oggs. Initially, a new group is created in
+ the 'building' state. All new streams will be added to the building group until
+ no-more-pads is signaled or one of the preroll queues overflows. When this happens,
+ the group is commited to a list of groups ready for playback. PlaybaseBin will then
+ attach a padprobe to each stream to figure out when it finished. It will remove
+ the current group and install the next playable group, then.
+
+ Before going to the PLAYING state, it is possible to connect a custom element to
+ each of the streams. To do that, you have to add the element to the bin and then
+ connect the pad(s) from the stream(s). You do not have to add the elements in
+ a thread, the bin will take care of then when it's needed. You are allowed to use
+ threads inside the elements, of course.
+ The bin tries to be smart and doesn't add a queue when there is only one possible
+ stream.
+
+
+ TODO
+ - reuse, cleanup in ready state
+ - when the first pad is closed, it's possible that another dynamic element is
+ added somewhere so that we need a queue for the first pad as well.
+
+
+playbin:
+
+ Extends playbasebin, sets up default audiosink and videosink for first audio/video
+ stream detected. implements seeking and querying on the configured sinks.
+
+ It also waits for new notifications from playbasebin about any new groups that are
+ becomming active. It then disconnects the sinks and reconnects them to the new
+ pads in the group.
+
+ TODO
+ - reuse, refcounting, cleanup in READY state
+ - be smarter about replugging the sinks instead of removing them and readding them.
+ - Do not crap out when the audio device is in use.
+
+
+general
+
+ TODO
+ - playlist support. maybe use a playlist bin that streams the contents of the
+ playlist on a pad, interleaved with new_media events. Also add a tuner

+ *
+ * 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.

+ - and increases bytes_to_serve
+ - (currently it sets streamheaders, but since this is treated globally
+ this is wrong - clients can be at different positions in the stream)

+ - when a client issues a write (ie requests data):
+ - when using GDP, if no caps sent yet, send caps first, then set caps_sent
+ - if streamheader buffers, and we haven't sent yet to this client,

- * @short_description: retimestamps and drops/duplicates video frames to
- * match the source pad's framerate and create a perfect stream
*
- * <refsect2>
- * <para>
* This element takes an incoming stream of timestamped video frames.
* It will produce a perfect stream that matches the source pad's framerate.
*
* The correction is performed by dropping and duplicating frames, no fancy
* algorithm is used to interpolate frames (yet).
- * </para>
- * <para>
+ *
* By default the element will simply negotiate the same framerate on its
* source and sink pad.
- * </para>
- * <para>
+ *
* This operation is useful to link to elements that require a perfect stream.
* Typical examples are formats that do not store timestamps for video frames,
* but only store a framerate, like Ogg and AVI.
- * </para>
- * <para>
+ *
* A conversion to a specific framerate can be forced by using filtered caps on
* the source pad.
- * </para>
- * <para>
- * The properties "in", "out", "duplicate" and "drop" can be read to obtain
- * information about number of input frames, output frames, dropped frames
- * (i.e. the number of unused input frames) and duplicated frames (i.e. the
- * number of times an input frame was duplicated, beside being used normally).
+ *
+ * The properties #GstVideoRate:in, #GstVideoRate:out, #GstVideoRate:duplicate
+ * and #GstVideoRate:drop can be read to obtain information about number of
+ * input frames, output frames, dropped frames (i.e. the number of unused input
+ * frames) and duplicated frames (i.e. the number of times an input frame was
+ * duplicated, beside being used normally).
*
* An input stream that needs no adjustments will thus never have dropped or
* duplicated frames.
*
- * When the "silent" property is set to FALSE, a GObject property notification
- * will be emitted whenever one of the "duplicate" or "drop" values changes.
+ * When the #GstVideoRate:silent property is set to FALSE, a GObject property
+ * notification will be emitted whenever one of the #GstVideoRate:duplicate or
+ * #GstVideoRate:drop values changes.
* This can potentially cause performance degradation.
* Note that property notification will happen from the streaming thread, so
* applications should be prepared for this.

- * breaks all compilations of old stuff...
- * The real problem is actually that linux/time.h doesn't use proper
- * macro checks before defining types like struct timeval. The proper
- * fix here is to either fuck the kernel header (which is what we do
- * by defining _LINUX_TIME_H, an innocent little hack) or by fixing it
- * upstream, which I'll consider doing later on. If you get compiler
- * errors here, check your linux/time.h && sys/time.h header setup.

-/**
- * SECTION:element-ximagesink
- *
- * <refsect2>
- * <para>
- * XImageSink renders video frames to a drawable (XWindow) on a local or 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>
- * As standard XImage rendering to a drawable is not scaled, XImageSink will use
- * reverse caps negotiation to try to get scaled video frames for the drawable.
- * This is accomplished by asking the peer pad if it accepts some different caps
- * which in most cases implies that there is a scaling element in the pipeline,
- * or that an element generating the video frames can generate them with a
- * different geometry. This mechanism is handled during buffer allocations, for
- * each allocation request the video sink will check the drawable geometry, look
- * at the
- * <link linkend="GstXImageSink--force-aspect-ratio">force-aspect-ratio</link>
- * 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>
- * </refsect2>

- * 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>

+The Smoke Codec
+---------------
+
+This is a very simple compression algorithm I was toying with when doing a
+Java based player. Decoding a JPEG in Java has acceptable speed so this codec
+tries to exploit that feature. The algorithm first compares the last and the
+new image and finds all 16x16 blocks that have a squared difference bigger than
+a configurable threshold. Then all these blocks are compressed into an NxM JPEG.
+The quality of the JPEG is inversely proportional to the number of blocks, this
+way, the picture quality degrades with heavy motion scenes but the bitrate stays
+more or less constant.
+Decoding decompresses the JPEG and then updates the old picture with the new
+blocks.
+
+
+TODO:
+----
+- make format extensible
+- motion vectors
+- do some real bitrate control

+ *
+ * Attenuates all frequencies outside (bandpass) or inside (bandreject) of a frequency
+ * band. The number of poles and the ripple parameter control the rolloff.
+ *
+ * This element has the advantage over the windowed sinc bandpass and bandreject filter that it is
+ * much faster and produces almost as good results. It's only disadvantages are the highly
+ * non-linear phase and the slower rolloff compared to a windowed sinc filter with a large kernel.
+ *
+ * For type 1 the ripple parameter specifies how much ripple in dB is allowed in the passband, i.e.
+ * some frequencies in the passband will be amplified by that value. A higher ripple value will allow
+ * a faster rolloff.
+ *
+ * For type 2 the ripple parameter specifies the stopband attenuation. In the stopband the gain will
+ * be at most this value. A lower ripple value will allow a faster rolloff.
+ *
+ * As a special case, a Chebyshev type 1 filter with no ripple is a Butterworth filter.
+ *
+ * <note>
+ * Be warned that a too large number of poles can produce noise. The most poles are possible with
+ * a cutoff frequency at a quarter of the sampling rate.

+ * Attenuates all frequencies above the cutoff frequency (low-pass) or all frequencies below the
+ * cutoff frequency (high-pass). The number of poles and the ripple parameter control the rolloff.
+ *
+ * This element has the advantage over the windowed sinc lowpass and highpass filter that it is
+ * much faster and produces almost as good results. It's only disadvantages are the highly
+ * non-linear phase and the slower rolloff compared to a windowed sinc filter with a large kernel.
+ *
+ * For type 1 the ripple parameter specifies how much ripple in dB is allowed in the passband, i.e.
+ * some frequencies in the passband will be amplified by that value. A higher ripple value will allow
+ * a faster rolloff.
+ *
+ * For type 2 the ripple parameter specifies the stopband attenuation. In the stopband the gain will
+ * be at most this value. A lower ripple value will allow a faster rolloff.
+ *
+ * As a special case, a Chebyshev type 1 filter with no ripple is a Butterworth filter.
+ * </para>
+ * <note><para>

+/**
+ * SECTION:element-audioecho
+ * @Since: 0.10.14
+ *
+ * audioecho adds an echo or (simple) reverb effect to an audio stream. The echo
+ * delay, intensity and the percentage of feedback can be configured.
+ *
+ * For getting an echo effect you have to set the delay to a larger value,
+ * for example 200ms and more. Everything below will result in a simple
+ * reverb effect, which results in a slightly metallic sound.
+ *
+ * Use the max-delay property to set the maximum amount of delay that
+ * will be used. This can only be set before going to the PAUSED or PLAYING
+ * state and will be set to the current delay by default.
+ *
+ * <refsect2>

+/**
+ * SECTION:element-audiofirfilter
+ *
+ * audiofirfilter implements a generic audio <ulink url="http://en.wikipedia.org/wiki/Finite_impulse_response">FIR filter</ulink>. Before usage the
+ * "kernel" property has to be set to the filter kernel that should be
+ * used and the "latency" property has to be set to the latency (in samples)
+ * that is introduced by the filter kernel. Setting a latency of n samples
+ * will lead to the first n samples being dropped from the output and
+ * n samples added to the end.
+ *
+ * The filter kernel describes the impulse response of the filter. To
+ * calculate the frequency response of the filter you have to calculate
+ * the Fourier Transform of the impulse response.
+ *
+ * To change the filter kernel whenever the sampling rate changes the
+ * "rate-changed" signal can be used. This should be done for most
+ * FIR filters as they're depending on the sampling rate.
+ *

+ * audioiirfilter implements a generic audio <ulink url="http://en.wikipedia.org/wiki/Infinite_impulse_response">IIR filter</ulink>. Before usage the
+ * "a" and "b" properties have to be set to the filter coefficients that
+ * should be used.
+ *
+ * The filter coefficients describe the numerator and denominator of the
+ * transfer function.
+ *
+ * To change the filter coefficients whenever the sampling rate changes the
+ * "rate-changed" signal can be used. This should be done for most
+ * IIR filters as they're depending on the sampling rate.

+/**
+ * SECTION:element-audiowsincband
+ *
+ * Attenuates all frequencies outside (bandpass) or inside (bandreject) of a frequency
+ * band. The length parameter controls the rolloff, the window parameter
+ * controls rolloff and stopband attenuation. The Hamming window provides a faster rolloff but a bit
+ * worse stopband attenuation, the other way around for the Blackman window.
+ *
+ * This element has the advantage over the Chebyshev bandpass and bandreject filter that it has
+ * a much better rolloff when using a larger kernel size and almost linear phase. The only
+ * disadvantage is the much slower execution time with larger kernels.

+ * SECTION:element-audiowsinclimit
+ *
+ * Attenuates all frequencies above the cutoff frequency (low-pass) or all frequencies below the
+ * cutoff frequency (high-pass). The length parameter controls the rolloff, the window parameter
+ * controls rolloff and stopband attenuation. The Hamming window provides a faster rolloff but a bit
+ * worse stopband attenuation, the other way around for the Blackman window.
+ *
+ * This element has the advantage over the Chebyshev lowpass and highpass filter that it has
+ * a much better rolloff when using a larger kernel size and almost linear phase. The only
+ * disadvantage is the much slower execution time with larger kernels.

+The avi decoder plugins
+-----------------------
+
+The avi decoder consists of a set of gstreamer plugins:
+
+ - demuxer (avidemux)
+ - avi to gstreamer type converter (avitypes)
+ - windows dlls wrappers.
+
+the avidecoder element uses the above plugins to perform the avi
+decoding. It is constructed as a custom bin which initially only has
+the demuxer element in it. The demuxer has a set of padtemplates for
+raw audio and video.
+
+ (------------------------------------)
+ ! avidecoder !
+ ! (video/raw)...
+ ! (----------) !
+ ! ! demuxer (video/x-msvideo, auds)..
+ ! ! ! !
+ ! -src ! !
+ ! / ! (video/x-msvideo, vids)..
+ - src ! ! !
+ ! (----------) (audio/raw)...
+ ! !
+ (------------------------------------)
+
+the demuxer has a set of padtemplates for the raw avi header properties.
+
+The avi decoder will act on the new_pad signal of the demuxer element
+and will attach an avitype plugin to the new pad. Caps negotiation will
+convert the raw avi caps to the gstreamer caps. If the src pad of the
+avitypes plugin are compatible with the avidecoder padtemplate, the
+avitype pad is ghosted to the avidecoder bin, this is the case where no
+codec is needed (for raw PCM samples, for example).
+
+When the avitypes caps are not compatible with one of the avidecoder
+templates, a static autoplugger is used the find an element to connect
+the demuxers pad to the decoders padtemplate.
+
+When no element could be found, an windec plugin is attached to the
+demuxers pad and the avitypes plugin is removed from the decoder.
+
+
+example:
+--------
+
+ An avidecoder that has a video pad (decoded with windows dlls) and an
+ audio pad (raw PCM).
+
+ (----------------------------------------------------------------)
+ ! avidecoder (--------) (------) !
+ ! !avitypes! !windec! /-- (video/raw)
+ ! (----------) /-sink src--sink src ----- !
+ ! !demuxer (video/x-msvideo, ! ! ! !
+ ! ! ! auds).. (--------) (------) !
+ ! -sink ! (--------) !
+ ! / ! (video/x-..,!avitypes! !
+ -sink ! ! vids).. ! ! !
+ ! (----------) \-sink src -------------------- (audio/raw)
+ ! (--------) !
+ (----------------------------------------------------------------)
+
+
+
+TODO
+----
+
+automatically generate the padtemplates from all possible avi types
+found in the registry.

+ * Quicktime has tracks and segments. A track is a continuous piece of
+ * multimedia content. The track is not always played from start to finish but
+ * instead, pieces of the track are 'cut out' and played in sequence. This is
+ * what the segments do.
+ *
+ * Inside the track we have keyframes (K) and delta frames. The track has its
+ * own timing, which starts from 0 and extends to end. The position in the track
+ * is called the media_time.
+ *
+ * The segments now describe the pieces that should be played from this track
+ * and are basically tupples of media_time/duration/rate entries. We can have
+ * multiple segments and they are all played after one another. An example:
+ *
+ * segment 1: media_time: 1 second, duration: 1 second, rate 1
+ * segment 2: media_time: 3 second, duration: 2 second, rate 2
+ *
+ * To correctly play back this track, one must play: 1 second of media starting
+ * from media_time 1 followed by 2 seconds of media starting from media_time 3
+ * at a rate of 2.
+ *
+ * Each of the segments will be played at a specific time, the first segment at
+ * time 0, the second one after the duration of the first one, etc.. Note that
+ * the time in resulting playback is not identical to the media_time of the
+ * track anymore.
+ *
+ * Visually, assuming the track has 4 second of media_time:
+ *
+ * (a) (b) (c) (d)
+ * .-----------------------------------------------------------.
+ * track: | K.....K.........K........K.......K.......K...........K... |
+ * '-----------------------------------------------------------'
+ * 0 1 2 3 4
+ * .------------^ ^ .----------^ ^
+ * / .-------------' / .------------------'
+ * / / .-----' /
+ * .--------------. .--------------.
+ * | segment 1 | | segment 2 |
+ * '--------------' '--------------'
+ *
+ * The challenge here is to cut out the right pieces of the track for each of
+ * the playback segments. This fortunatly can easily be done with the SEGMENT
+ * events of gstreamer.
+ *
+ * For playback of segment 1, we need to provide the decoder with the keyframe
+ * (a), in the above figure, but we must instruct it only to output the decoded
+ * data between second 1 and 2. We do this with a SEGMENT event for 1 to 2, time
+ * position set to the time of the segment: 0.
+ *
+ * We then proceed to push data from keyframe (a) to frame (b). The decoder
+ * decodes but clips all before media_time 1.
+ *
+ * After finishing a segment, we push out a new SEGMENT event with the clipping
+ * boundaries of the new data.
+ *
+ * This is a good usecase for the GStreamer accumulated SEGMENT events.

+ * SECTION:gstbufferlist
+ * @short_description: Grouped scatter data buffer type for data-passing
+ * @see_also: #GstPad, #GstMiniObject
+ *
+ * Buffer lists are units of grouped scatter/gather data transfer in
+ * GStreamer.
+ *
+ * Buffer lists are created with gst_buffer_list_new() and filled with data
+ * using a #GstBufferListIterator. The iterator has no current buffer; its
+ * cursor position lies between buffers, immediately before the buffer that
+ * would be returned by gst_buffer_list_iterator_next(). After iterating to the
+ * end of a group the iterator must be advanced to the next group by a call to
+ * gst_buffer_list_iterator_next_group() before any further calls to
+ * gst_buffer_list_iterator_next() can return buffers again. The cursor position
+ * of a newly created iterator lies before the first group; a call to
+ * gst_buffer_list_iterator_next_group() is necessary before calls to
+ * gst_buffer_list_iterator_next() can return buffers.
+ *
+ * <informalexample>
+ * <programlisting>
+ * +--- group0 ----------------------+--- group1 ------------+
+ * | buffer0 buffer1 buffer2 | buffer3 buffer4 |
+ * ^ ^ ^ ^ ^ ^ ^ ^
+ * Iterator positions
+ * </programlisting>
+ * </informalexample>
+ *
+ * The gst_buffer_list_iterator_remove(), gst_buffer_list_iterator_steal(),
+ * gst_buffer_list_iterator_take(), gst_buffer_list_iterator_do() and
+ * gst_buffer_list_iterator_do_data() functions are not defined in terms of the
+ * cursor position; they operate on the last element returned from
+ * gst_buffer_list_iterator_next().
+ *
+ * The basic use pattern of creating a buffer list with an iterator is as
+ * follows:
+ *
+ * <example>
+ * <title>Creating a buffer list</title>
+ * <programlisting>
+ * GstBufferList *list;
+ * GstBufferListIterator *it;
+ *
+ * list = gst_buffer_list_new ();
+ * it = gst_buffer_list_iterate (list);
+ * gst_buffer_list_iterator_add_group (it);
+ * gst_buffer_list_iterator_add (it, header1);
+ * gst_buffer_list_iterator_add (it, data1);
+ * gst_buffer_list_iterator_add_group (it);
+ * gst_buffer_list_iterator_add (it, header2);
+ * gst_buffer_list_iterator_add (it, data2);
+ * gst_buffer_list_iterator_add_group (it);
+ * gst_buffer_list_iterator_add (it, header3);
+ * gst_buffer_list_iterator_add (it, data3);
+ * ...
+ * gst_buffer_list_iterator_free (it);
+ * </programlisting>
+ * </example>
+ *
+ * The basic use pattern of iterating over a buffer list is as follows:
+ *
+ * <example>
+ * <title>Iterating a buffer list</title>
+ * <programlisting>
+ * GstBufferListIterator *it;
+ *
+ * it = gst_buffer_list_iterate (list);
+ * while (gst_buffer_list_iterator_next_group (it)) {
+ * while ((buffer = gst_buffer_list_iterator_next (it)) != NULL) {
+ * do_something_with_buffer (buffer);
+ * }
+ * }
+ * gst_buffer_list_iterator_free (it);
+ * </programlisting>
+ * </example>
+ *
+ * The basic use pattern of modifying a buffer in a list is as follows:
+ *
+ * <example>
+ * <title>Modifying the data of the first buffer in a list</title>
+ * <programlisting>
+ * GstBufferListIterator *it;
+ *
+ * list = gst_buffer_list_make_writable (list);
+ * it = gst_buffer_list_iterate (list);
+ * if (gst_buffer_list_iterator_next_group (it)) {
+ * GstBuffer *buf
+ *
+ * buf = gst_buffer_list_iterator_next (it);
+ * if (buf != NULL) {
+ * buf = gst_buffer_list_iterator_do (it,
+ * (GstBufferListDoFunction) gst_mini_object_make_writable, NULL);
+ * modify_data (GST_BUFFER_DATA (buf));
+ * }

+/**
+ * SECTION:gstpreset
+ * @short_description: helper interface for element presets
+ *
+ * This interface offers methods to query and manipulate parameter preset sets.
+ * A preset is a bunch of property settings, together with meta data and a name.
+ * The name of a preset serves as key for subsequent method calls to manipulate
+ * single presets.
+ * All instances of one type will share the list of presets. The list is created
+ * on demand, if presets are not used, the list is not created.
+ *
+ * The interface comes with a default implementation that serves most plugins.
+ * Wrapper plugins will override most methods to implement support for the
+ * native preset format of those wrapped plugins.
+ * One method that is useful to be overridden is gst_preset_get_property_names().
+ * With that one can control which properties are saved and in which order.
+ */
+/* FIXME:
+ * - non racyness
+ * - we need to avoid two instances writing the preset file
+ * -> flock(fileno()), http://www.ecst.csuchico.edu/~beej/guide/ipc/flock.html
+ * -> open exclusive
+ * -> better save the new file to a tempfile and then rename?
+ * - we like to know when any other instance makes changes to the keyfile
+ * - then ui can be updated
+ * - and we make sure that we don't lose edits
+ * -> its the same problem actually, once for inside a process, once system-
+ * wide
+ * - can we use a lock inside a names shared memory segment?
+ *
+ * - need to add support for GstChildProxy
+ * we can do this in a next iteration, the format is flexible enough
+ * http://www.buzztard.org/index.php/Preset_handling_interface
+ *
+ * - should there be a 'preset-list' property to get the preset list
+ * (and to connect a notify:: to to listen for changes)
+ * we could use gnome_vfs_monitor_add() to monitor the user preset_file.
+ *
+ * - should there be a 'preset-name' property so that we can set a preset via
+ * gst-launch, or should we handle this with special syntax in gst-launch:
+ * gst-launch element preset:<preset-name> property=value ...
+ * - this would alloow to hanve preset-bundles too (a preset on bins that
+ * specifies presets for children
+ *
+ * - GstChildProxy suport
+ * - if we stick with GParamSpec **_list_properties()
+ * we need to use g_param_spec_set_qdata() to specify the instance on each GParamSpec
+ * OBJECT_LOCK(obj); // ChildProxy needs GstIterator support
+ * num=gst_child_proxy_get_children_count(obj);

+ *
+ * For source pads, the probe will be called after the blocking function, if any
+ * (see gst_pad_set_blocked_async()), but before looking up the peer to chain
+ * to. For sink pads, the probe function will be called before configuring the
+ * sink with new caps, if any, and before calling the pad's chain function.
+ *
+ * Your data probe should return TRUE to let the data continue to flow, or FALSE
+ * to drop it. Dropping data is rarely useful, but occasionally comes in handy
+ * with events.
+ *
+ * Although probes are implemented internally by connecting @handler to the

+ * to only call g_signal_handler_disconnect on the returned handler id. To
