Looks for the properties defines with the various parametters and add them to the hashtable of children properties.

To be used by subclasses only

self :

The GESTrackElement to set chidlren props on

element :

The GstElement to retrieve properties from

wanted_categories :

An array of categories of GstElement to take into account (as defined in the factory meta "klass" field). [array zero-terminated=1][transfer none][allow-none]

blacklist :

A blacklist of elements factory names to not take into account. [array zero-terminated=1][transfer none][allow-none]

whitelist :

A list of propery names to add as children properties. [array zero-terminated=1][transfer none][allow-none]
