-/**
- * 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.
