libs: remove gdp dataprotocol library
Made private and moved to gdp plugin in -base for the time being, until we figure out what we do with gdp and 0.11.

/**
|
|

* 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:
