gstreamer plugin function code flow

[Mayank Agarwal]

Hi,

I am trying to understand the function code flow of gstreamer plugin:

1.<plugin_name_init> function is called when thee plugin in referenced
in the pipeline.
2.chain function is the function in which all processing takes place
and is called when any data is available
at the src pad.
3.class_init function is called when the plugin object is instantiated
in the plugin class.


Please verify my above understanding:also please add about the
function calling sequence in gstreamer.

Regards,
Mayank
