<!-- ##### SECTION Short_Description ##### -->
|
|
implements GStreamer Data Protocol to serialize buffers, caps and events.
|
|
|
|
<!-- ##### SECTION Long_Description ##### -->
|
|
<para>
|
|
This helper library provides serialization of GstBuffer, GstCaps and
|
|
GstEvent structures.
|
|
</para>
|
|
|
|
<para>
|
|
This serialization can be useful when GStreamer needs to interface with
|
|
the outside world to transport data between different GStreamer pipelines.
|
|
The connections with the outside world generally don't have mechanisms
|
|
to transport properties of these structures.
|
|
</para>
|
|
<para>
|
|
For example, transporting buffers across named pipes doesn't keep the
|
|
buffer size. Network elements that transport GStreamer data across
|
|
network connections also need a protocol to do this.
