/**
* SECTION:gstbasesrc
* @short_description: Base class for getrange based source elements
* @see_also: #GstPushSrc, #GstBaseTransform, #GstBaseSink
*
* This is a generice base class for source elements. The following
* types of sources are supported:
* <itemizedlist>
* <listitem><para>random access sources like files</para></listitem>
* <listitem><para>seekable sources</para></listitem>
* <listitem><para>live sources</para></listitem>
* </itemizedlist>
*
* The source can be configured to operate in a any #GstFormat with the
* gst_base_src_set_format(). This format determines the format of the
* internal #GstSegment and the #GST_EVENT_NEW_SEGMENT. The default format for
* #GstBaseSrc is GST_FORMAT_BYTES.
*
* #GstBaseSrc always supports the push mode scheduling. If the following
* conditions are met, it also supports pull mode scheduling:
* <itemizedlist>
* <listitem><para>the format is set to GST_FORMAT_BYTES (default).</para></listitem>
* <listitem><para>#GstBaseSrc::is_seekable returns TRUE.</para></listitem>
* </itemizedlist>
*
* If all the conditions are met for operating in pull mode, #GstBaseSrc is
* automatically seekable in push mode as well. The following conditions must be
* met to make the element seekable in push mode when the format is not
* GST_FORMAT_BYTES:
* <itemizedlist>
* <listitem><para>
* #GstBaseSrc::is_seekable returns TRUE.
* </para></listitem>
* <listitem><para>
* #GstBaseSrc::query can convert all supported seek formats to the
* internal format as set with gst_base_src_set_format().
* </para></listitem>
* <listitem><para>
* #GstBaseSrc::do_seek is implemented, performs the seek and returns TRUE.
* </para></listitem>
* </itemizedlist>
*
* When the default format is not GST_FORMAT_BYTES, the element should ignore the
* offset and length in the #GstBaseSrc::create method. It is recommended to subclass
* #GstPushSrc instead in this situation.
*
* #GstBaseSrc has support for live sources. Live sources are sources that produce
* data at a fixed rate, such as audio or video capture. A typical live source also
* provides a clock to export the rate at which they produce data.
* Use gst_base_src_set_live() to activate the live source mode.
*
* A live source does not produce data in the PAUSED state, this means that the
* #GstBaseSrc::create method will not be called in PAUSED but only in PLAYING.
* To signal the pipeline that the element will not produce data, its return
* value from the READY to PAUSED state will be GST_STATE_CHANGE_NO_PREROLL.
*
* A typical live source will timestamp the buffers they create with the current
* stream time of the pipeline. This is why they can only produce data in PLAYING,
* when the clock is actually distributed and running.
*
* The #GstBaseSrc::get_times method can be used to implement pseudo-live sources.
* The base source will wait for the specified stream time returned in
* #GstBaseSrc::get_times before pushing out the buffer. It only makes sense to implement
* the ::get_times function if the source is a live source.
*
* There is only support in GstBaseSrc for one source pad, which should be named
* "src". A source implementation (subclass of GstBaseSrc) should install a pad
* template in its base_init function, like so:
*
* <programlisting>
* static void
* my_element_base_init (gpointer g_class)
* {
* GstElementClass *gstelement_class = GST_ELEMENT_CLASS (g_class);
* // srctemplate should be a #GstStaticPadTemplate with direction
* // #GST_PAD_SRC and name "src"
* gst_element_class_add_pad_template (gstelement_class,
* gst_static_pad_template_get (&amp;srctemplate));
* // see #GstElementDetails
* gst_element_class_set_details (gstelement_class, &amp;details);
* }
* </programlisting>
*

gst/gstquery.h Original commit message from CVS: 2005-05-06 Andy Wingo <wingo@pobox.com> * gst/gstquery.h * gst/gstquery.c (_gst_query_initialize): Extend GstQuery from GstData, init a memchunk. (standard_definitions): Add a few query types, deprecate a few. (gst_query_get_type): New proc. (_gst_query_copy, _gst_query_free, gst_query_new): GstData implementation. (gst_query_new_application, gst_query_get_structure): New public procs. * docs/design/draft-query.txt: Removed LINKS from the query types, because all the rest can be dispatched to other pads -- seemed ugly to have a query that couldn't be dispatched. internal_links is fine as a pad method. * gst/gstpad.h: Add query2 as a pad method, add the new functions in gstpad.c, but maintain binary compatibility for the moment. Will fix before 0.9 is out. * gst/gstqueryutils.c: * gst/gstqueryutils.h: New files, implement 3 methods for each query type: parse_query, parse_response, and set. Probably need an allocator as well. * gst/gst.h: Add gstquery.h and gstqueryutils.h to the list. * gst/elements/gstfilesink.c (gst_filesink_query2): * gst/base/gstbasesrc.c (gst_basesrc_query2): Replace old query, query_types, and formats methods. * gst/gstpad.c (gst_pad_query2, gst_pad_query2_default) (gst_pad_set_query2_function): New functions. (gst_real_pad_init): Set query2_default as the default query2 function. Basically just dispatches to internally linked pads. Needs review! * gst/gstdata_private.h (_GST_DATA_INIT): Set data->refcount to 1 without using the atomic operations. Only one thread can possibly be accessing the data at this point. Changed so as to avoid gst_atomic operations.

(gst_query_new_application, gst_query_get_structure): New public procs. * docs/design/draft-query.txt: Removed LINKS from the query types, because all the rest can be dispatched to other pads -- seemed ugly to have a query that couldn't be dispatched. internal_links is fine as a pad method. * gst/gstpad.h: Add query2 as a pad method, add the new functions in gstpad.c, but maintain binary compatibility for the moment. Will fix before 0.9 is out. * gst/gstqueryutils.c: * gst/gstqueryutils.h: New files, implement 3 methods for each query type: parse_query, parse_response, and set. Probably need an allocator as well. * gst/gst.h: Add gstquery.h and gstqueryutils.h to the list. * gst/elements/gstfilesink.c (gst_filesink_query2): * gst/base/gstbasesrc.c (gst_basesrc_query2): Replace old query, query_types, and formats methods. * gst/gstpad.c (gst_pad_query2, gst_pad_query2_default) (gst_pad_set_query2_function): New functions. (gst_real_pad_init): Set query2_default as the default query2 function. Basically just dispatches to internally linked pads. Needs review! * gst/gstdata_private.h (_GST_DATA_INIT): Set data->refcount to 1 without using the atomic operations. Only one thread can possibly be accessing the data at this point. Changed so as to avoid gst_atomic operations.

/* this code implements the seeking. It is a good example
* handling all cases.
*
* A seek updates the currently configured segment.start
* and segment.stop values based on the SEEK_TYPE. If the
* segment.start value is updated, a seek to this new position
* should be performed.
*
* The seek can only be executed when we are not currently
* streaming any data, to make sure that this is the case, we
* acquire the STREAM_LOCK which is taken when we are in the
* _loop() function or when a getrange() is called. Normally
* we will not receive a seek if we are operating in pull mode
* though.
*
* When we are in the loop() function, we might be in the middle
* of pushing a buffer, which might block in a sink. To make sure
* that the push gets unblocked we push out a FLUSH_START event.
* Our loop function will get a WRONG_STATE return value from
* the push and will pause, effectively releasing the STREAM_LOCK.
*
* For a non-flushing seek, we pause the task, which might eventually
* release the STREAM_LOCK. We say eventually because when the sink
* blocks on the sample we might wait a very long time until the sink
* unblocks the sample. In any case we acquire the STREAM_LOCK and
* can continue the seek. A non-flushing seek is normally done in a
* running pipeline to perform seamless playback.
* In the case of a non-flushing seek we need to make sure that the
* data we output after the seek is continuous with the previous data,
* this is because a non-flushing seek does not reset the stream-time
* to 0. We do this by closing the currently running segment, ie. sending
* a new_segment event with the stop position set to the last processed
* position.
*
* After updating the segment.start/stop values, we prepare for
* streaming again. We push out a FLUSH_STOP to make the peer pad
* accept data again and we start our task again.
*
* A segment seek posts a message on the bus saying that the playback
* of the segment started. We store the segment flag internally because
* when we reach the segment.stop we have to post a segment.done
* instead of EOS when doing a segment seek.
