GstElement

Base class for all pipeline elements

<para>
|
|
GstElement is the base class needed to construct an element that can be
|
|
used in a GST pipeline. As such, it is not a functional entity, and
|
|
cannot do anything when placed in a pipeline.
|
|
</para>
|
|
|
|
<para>
|
|
All GstElements have a list containing the #GstPad structure for all their
|
|
inputs and outputs. These can be added with gst_element_add_pad() or
|
|
gst_element_add_ghost_pad(), and retrieved by name with
|
|
gst_element_get_pad(), or in a list form by gst_element_get_pad_list().
|
|
</para>
|
|
|
|
<para>
|
|
gst_element_connect() is a convenience function provided to make it
|
|
simpler to connect pads of two elements together.
