GStreamer data protocol
Intended to wrap GstData objects in a line protocol for use with
pipe / network elements.
IDEAS
-----
* for transporting buffers, have a function that creates a header for
a given buffer to be written before the buffer. This way, you don't lose
IDEAS-- -- -*for transporting buffers, have a function that creates a header for a given buffer to be written before the buffer.This way, you don 't lose
time creating a GDP buffer from the buffer
* allow for CRC'ing of the GstBuffer, optionally
* have a version number of the protocol
* optimizing the header for size is not useful since the GstData structure
already contains more than 32 bytes anyway, making up half the header size

PROTOCOL CHANGELOG
------------------
0.1: added two bytes for buffer flags
all numbers use network byte ordering.
