     37  *********************************************************************************************
     38  This is the proxy specific wrapper that passes the component name to the generic proxy init()
     39  The proxy wrapper also does some runtime/static time onfig on per proxy basis
     40  This is a thin wrapper that is called when componentiit() of the proxy is called
     41  static OMX_ERRORTYPE PROXY_Wrapper_init(OMX_HANDLETYPE hComponent, OMX_PTR pAppData);
     42  this layer gets called first whenever a proxy s get handle is called
