As I know, the CCExtractor uses its own freep as a wrapper for free

[sidgairo18]

In this case free() does the job.
freep() is for deallocating double pointers. See function definition-

void freep(void *arg)                                                   
{                                                                       
    void **ptr = (void **)arg;                                          
    if (*ptr)                                                           
        free(*ptr);                                                     
    *ptr = NULL;                                                        
                                                                        
}
