Structs

Adapter	This class is for elements that receive buffers in an undesired size. While for example raw video contains one image per buffer, the same is not true for a lot of other formats, especially those that come directly from a file. So if you have undefined buffer sizes and require a specific size, this object is for you.
AdapterClass
Aggregator	Manages a set of pads with the purpose of aggregating their buffers. Control is given to the subclass when all pads have data.
AggregatorClass
AggregatorPad	Pads managed by a GstAggregor subclass.
AggregatorPadClass
BaseParse	This base class is for parser elements that process data and splits it into separate audio/video/whatever frames.

BaseSink	BaseSink is the base class for sink elements in GStreamer, such as xvimagesink or filesink. It is a layer on top of gst::Element that provides a simplified interface to plugin writers. BaseSink handles many details for you, for example: preroll, clock synchronization, state changes, activation in push or pull mode, and queries.
BaseSinkClass
BaseSrc	This is a generic base class for source elements. The following types of sources are supported:
BaseSrcClass
BaseTransform	This base class is for filter elements that process data. Elements that are suitable for implementation using BaseTransform are ones where the size and caps of the output is known entirely from the input caps and buffer sizes. These include elements that directly transform one buffer into another, modify the contents of a buffer in-place, as well as elements that collate multiple input buffers into one output buffer, or that expand one input buffer into multiple output buffers. See below for more concrete use cases.
BaseTransformClass
FlowCombiner	Utility struct to help handling gst::FlowReturn combination. Useful for gst::Elements that have multiple source pads and need to combine the different gst::FlowReturn for those pads.
PushSrc	This class is mostly useful for elements that cannot do random access, or at least very slowly. The source usually prefers to push out a fixed size buffer.
