+/**
+ * SECTION: gstaggregator
+ * @title: GstAggregator
+ * @short_description: manages a set of pads with the purpose of
+ * aggregating their buffers.
+ * @see_also: gstcollectpads for historical reasons.
+ *
+ * Manages a set of pads with the purpose of aggregating their buffers.
+ * Control is given to the subclass when all pads have data.
+ *
+ * * Base class for mixers and muxers. Subclasses should at least implement
+ * the #GstAggregatorClass.aggregate() virtual method.
+ *
+ * * Installs a #GstPadChainFunction, a #GstPadEventFullFunction and a
+ * #GstPadQueryFunction to queue all serialized data packets per sink pad.
+ * Subclasses should not overwrite those, but instead implement
+ * #GstAggregatorClass.sink_event() and #GstAggregatorClass.sink_query() as
+ * needed.
+ *
+ * * When data is queued on all pads, the aggregate vmethod is called.
+ *
+ * * One can peek at the data on any given GstAggregatorPad with the
+ * gst_aggregator_pad_get_buffer () method, and take ownership of it
+ * with the gst_aggregator_pad_steal_buffer () method. When a buffer
+ * has been taken with steal_buffer (), a new buffer can be queued
+ * on that pad.
+ *
+ * * If the subclass wishes to push a buffer downstream in its aggregate
+ * implementation, it should do so through the
+ * gst_aggregator_finish_buffer () method. This method will take care
+ * of sending and ordering mandatory events such as stream start, caps
+ * and segment.
+ *
+ * * Same goes for EOS events, which should not be pushed directly by the
+ * subclass, it should instead return GST_FLOW_EOS in its aggregate
+ * implementation.
+ *
+ * * Note that the aggregator logic regarding gap event handling is to turn
+ * these into gap buffers with matching PTS and duration. It will also
+ * flag these buffers with GST_BUFFER_FLAG_GAP and GST_BUFFER_FLAG_DROPPABLE
+ * to ease their identification and subsequent processing.

+ * clipping of input buffer. This function takes ownership of

+ * if the buffer should be dropped.
+ * @sink_event: Optional.

+ * should always chain up.
+ * @sink_query: Optional.
+ * Called when a query is received on a sink pad, the subclass
+ * should always chain up.
+ * @src_event: Optional.

+ * should always chain up.
+ * @src_query: Optional.
+ * Called when a query is received on the src pad, the subclass
+ * should always chain up.
+ * @src_activate: Optional.
+ * Called when the src pad is activated, it will start/stop its
+ * pad task right after that call.
+ * @aggregate: Mandatory.
+ * Called when buffers are queued on all sinkpads. Classes
+ * should iterate the GstElement->sinkpads and peek or steal
+ * buffers from the #GstAggregatorPads. If the subclass returns
+ * GST_FLOW_EOS, sending of the eos event will be taken care
+ * of. Once / if a buffer has been constructed from the
+ * aggregated buffers, the subclass should call _finish_buffer.
+ * @stop: Optional.
+ * Called when the element goes from PAUSED to READY.
+ * The subclass should free all resources and reset its state.
+ * @start: Optional.
+ * Called when the element goes from READY to PAUSED.
+ * The subclass should get ready to process
+ * aggregated buffers.
+ * @get_next_time: Optional.
+ * Called when the element needs to know the running time of the next
+ * rendered buffer for live pipelines. This causes deadline
+ * based aggregation to occur. Defaults to returning
+ * GST_CLOCK_TIME_NONE causing the element to wait for buffers
+ * on all sink pads before aggregating.
+ * @update_src_caps: Lets subclasses update the #GstCaps representing
+ * the src pad caps before usage. The result should end up
+ * in @ret. Return %GST_AGGREGATOR_FLOW_NEED_DATA to indicate that the
+ * element needs more information (caps, a buffer, etc) to
+ * choose the correct caps. Should return ANY caps if the
+ * stream has not caps at all.
+ * @fixate_src_caps: Optional.
+ * Fixate and return the src pad caps provided. The function takes
+ * ownership of @caps and returns a fixated version of
+ * @caps. @caps is not guaranteed to be writable.
+ * @negotiated_src_caps: Optional.
+ * Notifies subclasses what caps format has been negotiated
+ * @decide_allocation: Optional.
+ * Allows the subclass to influence the allocation choices.
+ * Setup the allocation parameters for allocating output
+ * buffers. The passed in query contains the result of the
+ * downstream allocation query.
+ *
+ * The aggregator base class will handle in a thread-safe way all manners of
+ * concurrent flushes, seeks, pad additions and removals, leaving to the
+ * subclass the responsibility of clipping buffers, and aggregating buffers in
+ * the way the implementor sees fit.
+ *
+ * It will also take care of event ordering (stream-start, segment, eos).
+ *
+ * Basically, a simple implementation will override @aggregate, and call
+ * _finish_buffer from inside that function.
