DESCRIPTION

38       MP4SetVerbosity allows control over the level of diagnostic information
39       printed out by the library. It can be called at any time. Since much is
40       done  by  the  library when opening an mp4 file, this function is built
41       into functions such as MP4Create(), MP4Modify(), and MP4Read().
