creator of the requested openmax component
This function searches for the requested component in the internal list. If the component is found, its constructor is called, and the standard callback are assigned. A pointer to a standard openmax component is returned.

The constructor of the ST specific component loader.
It is the component loader developed under linux by ST, for local libraries. It is based on a registry file, like in the case of GStreamer. It reads the registry file, and allows the components to register themself to the main list templateList.
The constructor of the ST specific component loader.
This function creates the ST static component loader, and creates the list of available components, based on a registry file created by a separate appication. It is called omxregister, and must be called before the use of this loader
