<p>Called by the standard allocate buffer, it implements a base functionality. </p>
<p>This function can be overriden if the allocation of the buffer is not a simply alloc call. The parameters are the same as the standard function, except for the handle of the port instead of the handler of the component When the buffers needed by this port are all assigned or allocated, the variable bIsFullOfBuffers becomes equal to OMX_TRUE </p>
