/**
* SECTION:gstbasesink
* @short_description: Base class for sink elements
* @see_also: #GstBaseTransform, #GstBaseSource
*
* #GstBaseSink is the base class for sink elements in GStreamer, such as
* xvimagesink or filesink. It is a layer on top of #GstElement that provides a
* simplified interface to plugin writers. #GstBaseSink handles many details for
* you, for example preroll, clock synchronization, state changes, activation in
* push or pull mode, and queries. In most cases, when writing sink elements,
* there is no need to implement class methods from #GstElement or to set
* functions on pads, because the #GstBaseSink infrastructure is sufficient.
*
* There is only support in GstBaseSink for one sink pad, which should be named
* "sink". A sink implementation (subclass of GstBaseSink) 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);
*
* // sinktemplate should be a #GstStaticPadTemplate with direction
* // #GST_PAD_SINK and name "sink"
* gst_element_class_add_pad_template (gstelement_class,
* gst_static_pad_template_get (&amp;sinktemplate));
* // see #GstElementDetails
* gst_element_class_set_details (gstelement_class, &amp;details);
* }
* </programlisting>
*
* #GstBaseSink will handle the prerolling correctly. This means that it will
* return GST_STATE_CHANGE_ASYNC from a state change to PAUSED until the first buffer
* arrives in this element. The base class will call the GstBaseSink::preroll
* vmethod with this preroll buffer and will then commit the state change to
* PAUSED.
*
* When the element is set to PLAYING, #GstBaseSink will synchronize on the clock
* using the times returned from ::get_times. If this function returns
* #GST_CLOCK_TIME_NONE for the start time, no synchronisation will be done.
* Synchronisation can be disabled entirely by setting the object "sync" property
* to FALSE.
*
* After synchronisation the virtual method #GstBaseSink::render will be called.
* Subclasses should minimally implement this method.
*
* Upon receiving the EOS event in th PLAYING state, #GstBaseSink will wait for
* the clock to reach the time indicated by the stop time of the last ::get_times
* call before posting an EOS message. When the element receives EOS in PAUSED,
* the event is queued and an EOS message is posted when going to PLAYING.
*
* #GstBaseSink will internally use the GST_EVENT_NEW_SEGMENT events to schedule
* synchronisation and clipping of buffers. Buffers that fall completely outside
* of the segment are dropped. Buffers that fall partially in the segment are
* rendered (and prerolled), subclasses should do any subbuffer clipping themselves
* when needed.
*
* #GstBaseSink will by default report the current playback position in
* GST_FORMAT_TIME based on the current clock time and segment information.
* If the element is EOS however, the query will be forwarded upstream.
*
* The ::set_caps function will be called when the subclass should configure itself
* to precess a specific media type.
*
* The ::start and ::stop virtual methods will be called when resources should be
* allocated. Any ::preroll, ::render and ::set_caps function will be called
* between the ::start and ::stop calls.
*
* The ::event virtual method will be called when an event is received by
* #GstBaseSink. Normally this method should only be overriden by very specific
* elements such as file sinks that need to handle the newsegment event specially.
*
* #GstBaseSink provides an overridable ::buffer_alloc function that can be used
* by specific sinks that want to do reverse negotiation or want to provided
* hardware accelerated buffers for downstream elements.
*
* The ::unlock method is called when the elements should unblock any blocking
* operations they perform in the ::render method. This is mostly usefull when
* the ::render method performs a blocking write on a file descripter.

gst/gstutils.c: RPAD fixes all around. Original commit message from CVS: 2005-06-08 Andy Wingo <wingo@pobox.com> * gst/gstutils.c: RPAD fixes all around. (gst_element_link_pads): Refcounting fixes. * tools/gst-inspect.c: * tools/gst-xmlinspect.c: * parse/grammar.y: * gst/base/gsttypefindhelper.c: * gst/base/gstbasesink.c: * gst/gstqueue.c: RPAD fixes. * gst/gstghostpad.h: * gst/gstghostpad.c: New ghost pad implementation as full proxy pads. The tricky thing is they provide both source and sink interfaces, since they proxy the internal pad for the external pad, and vice versa. Implement with lower-level ProxyPad objects, with the interior proxy pad as a child of the exterior ghost pad. Should write a doc on this. * gst/gstpad.h: s/RPAD/PAD/, s/RealPad/Pad/. (gst_pad_set_name, gst_pad_set_parent): Macros removed, use gst_object API. * gst/gstpad.c: Big changes. No more stub base GstPad, now all pads are real pads. No ghost pads in this file. Not documenting the myriad s/RPAD/PAD/ and REALIZE fixes. (gst_pad_class_init): Add properties for "direction" and "template". Both are construct-only, so they can't change during the life of the pad. Fixes properly deriving from GstPad. (gst_pad_custom_new, gst_pad_custom_new_from_template): Gone. For derived objects, just set properties when creating the objects via g_object_new. (gst_pad_get_parent): Implement as a function, return NULL if the parent is not an element. (gst_pad_get_real_parent, gst_pad_add_ghost_pad) (gst_pad_remove_ghost_pad, gst_pad_realize): Removed. * gst/gstobject.c (gst_object_class_init): Make name a construct property. Don't set it in the object init. * gst/gstelement.c (gst_element_add_pad): Don't allow adding pads with UNKNOWN direction. (gst_element_add_ghost_pad): Remove non-orthogonal API. Replace with gst_element_add_pad (e, gst_ghost_pad_new (name, pad)). (gst_element_remove_pad): Remove ghost-pad special cases. (gst_element_pads_activate): Remove rpad cruft. * gst/gstbin.c (gst_bin_change_state): Use gst_pad_get_parent to catch the pad's-parent-not-an-element case. * gst/gst.h: Include gstghostpad.h. * gst/gst.c (init_post): No more real, ghost pads. * gst/Makefile.am: Add gstghostpad.[ch]. * check/Makefile.am: * check/gst/gstbin.c: * check/gst/gstghostpad.c (test_ghost_pads): Check that linking into a bin creates ghost pads, and that the refcounts are right. Partly moved from gstbin.c.
