func MetaDataReform(p []byte, flag byte) ([]byte, error)

func ReadBoolean 

func ReadBoolean(r Reader) (b bool, err error)

func ReadDate 

func ReadDate(r Reader) (t time.Time, err error)

An ActionScript Date is serialized as the number of milliseconds elapsed since the epoch of midnight on 1st Jan 1970 in the UTC time zone. While the design of this type reserves room for time zone offset information, it should not be filled in, nor used, as it is unconventional to change time zones when serializing dates on a network. It is suggested that the time zone be queried independently as needed. time-zone = S16 ; reserved, 

; not supported
; should be set

Keng-die: time-zone = int16 * -60 (seconds) 

; to 0x0000

date-type = date-marker DOUBLE time-zone

func ReadDouble 

func ReadDouble(r Reader) (num float64, err error)

func ReadMarker 

func ReadMarker(r Reader) (mark byte, err error)

----------------------------------------------------------------------- AMF0 Read functions

func ReadObjectName 

func ReadObjectName(r Reader) (name string, err error)

func ReadStrictArray 

func ReadStrictArray(r Reader) (arr []interface{}, err error)

A strict Array contains only ordinal indices; however, in AMF 0 the indices can be dense or sparse. Undefined entries in the sparse regions between indices are serialized as undefined.

array-count = U32 strict-array-type = array-count *(value-type)

A 32-bit array-count implies a theoretical maximum of 4,294,967,295 array entries.
