/**
* SECTION:gstdataprotocol
* @short_description: Serialization of caps, buffers and events.
* @see_also: #GstCaps, #GstEvent, #GstBuffer
*
* This helper library provides serialization of GstBuffer, GstCaps and
* GstEvent structures.
*
* This serialization is useful when GStreamer needs to interface with
* the outside world to transport data between distinct GStreamer pipelines.
* The connections with the outside world generally don't have mechanisms
* to transport properties of these structures.
*
* For example, transporting buffers across named pipes or network connections
* doesn't maintain the buffer size and separation.
*
* This data protocol assumes a reliable connection-oriented transport, such as
* TCP, a pipe, or a file. The protocol does not serialize the caps for
* each buffer; instead, it transport the caps only when they change in the
* stream. This implies that there will always be a caps packet before any
* buffer packets.
*
* The versioning of the protocol is independent of GStreamer's version.
* The major number gets incremented, and the minor reset, for incompatible
* changes. The minor number gets incremented for compatible changes that
* allow clients who do not completely understand the newer protocol version
* to still decode what they do understand.
*
* Version 0.2 serializes only a small subset of all events, with a custom
* payload for each type. Also, all GDP streams start with the initial caps
* packet.
*
* Version 1.0 serializes all events by taking the string representation of
* the event as the payload. In addition, GDP streams can now start with
* events as well, as required by the new data stream model in GStreamer 0.10.
*
* Converting buffers, caps and events to GDP buffers is done using a
* #GstDPPacketizer object and invoking its packetizer functions.
* For backwards-compatibility reasons, the old 0.2 methods are still
* available but deprecated.
*
* For reference, this image shows the byte layout of the GDP header:
*
* <inlinegraphic format="PNG" fileref="gdp-header.png"></inlinegraphic>
