- * 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:
