|hFile||Specifies the mp4 file to which the operation applies.|
Specifies a bitmask of diagnostic details the library should print to stdout during its functioning. The default is to operate silently. Possible values are:
MP4_DETAILS_ERROR Reasons for errors
MP4_DETAILS_READ Read operations
MP4_DETAILS_WRITE Write operations
MP4_DETAILS_FIND Find property operations
MP4_DETAILS_TABLE Per table entry info
MP4_DETAILS_SAMPLE Per sample info
MP4_DETAILS_HINT Per RTP hint info
MP4_DETAILS_ALL All possible details
Upon success, true (1). Upon an error, false (0).
MP4SetVerbosity allows control over the level of diagnostic information printed out by the library. It can be called at any time. Since much is done by the library when opening an mp4 file, this function is built into functions such as MP4Create(), MP4Modify(), and MP4Read().
