Public Methods

Method	Description
AddChild ( Box child ) : void	Add a child box into this box. Child box should be a sub-class of Box (i.e. not a generic 'Box')
Box ( string FOURCC ) : System	Create a generic box
BoxDate ( System.DateTime date ) : System.UInt64	Gives a date as a number of seconds since 1904-01-01 T 00:00
FourCC ( string fourcc ) : UInt32	Convert a four character code string into a 32 bit int, suitable for writing with 'BigEndianWriter'
Prepare ( ) : void	Prepare for data gathering. Your '_data' members should be populated here at the latest.
deepData ( ) : byte[]	Return data for this and all children, in correct order. You probably don't need to override this
deepSize ( ) : ulong	Size of self plus all children (container size). Includes size for FOURCC and basic 'FullBox' flags. You probably don't need to override this

Protected Methods

Method	Description
NetToMpgTicks ( ulong MpgTicks ) : ulong	Convert .Net ticks (100ns) to Mpeg ticks (90MHz)
selfData ( ) : byte[]	Output the header data for this Box. Override this to add extra data if your sub-class adds extra fields
selfSize ( ) : ulong	Size of self, disregarding children (in bytes) Override this to add extra size to base() if your sub-class adds extra fields
