func (*Packet) GetDataUnsafe 

func (pkt *Packet) GetDataUnsafe() []byte

GetDataUnsafe returns a Go slice backed by the underlying C array representing the data of the packet. This slice is not managed by Go garbage collection. The behaviour if the underlying array is freed and then the slice returned by this function is accessed is undefined (read: best-case scenario, panics, worst-case, insidious memory-access errors that will cause you to doubt your own sanity). USE ONLY IF YOU KNOW WHAT YOU'RE DOING. Assume an underlying array of 65,536 bytes will be sufficient for storing data from a packet. This may need to be updated if this is used for things other than MPEGTS packets.
