	// Version specifies the version of RTP used in the Packet.

	// Marker indicates the marker bit is set. The payload type
	// determines how this value is interpreted.
	Marker bool

	// Type specifies the format of the payload transported in the Packet.
	// In general, each type has its own IETF RFC specifying how the payload is encoded.
	// For example, PayloadMP2T is detailed in RFC 2250.

	// Sequence is a monotonically incremented number used by
	// receivers to manage packet loss. The first packet's Sequence
	// should be randomly assigned, then incremented by one for each
	// RTP packet transmitted.
	Sequence uint16

	// Timestamp is the instant sampled of the first byte of the packet.
	// The first packet in a session should have a randomly assigned
	// timestamp. Subsequent timestamps are calculated according to a
	// monotonically incrementing clock. The clock frequency, and how the
	// timestamp should be interpreted, is dictated by the payload type. For
	// instance, the Timestamp field of RTP packets with MPEG payloads
	// represents the number of ticks of a 90KHz clock. Timestamps of GSM
	// audio RTP packets represent ticks of a 8KHz clock.
	Timestamp uint32

	// SyncSource identifies the synchronisation source of the RTP
	// session. It should be randomly assigned at the start of a
	// session and remain unchanged throughout to prevent
	// collisions with other sessions.
	SyncSource uint32

	// ContribSource lists a maximum of 15 contribution sources
	// used to generate the payload. For example, a RTP session for
	// audio transport may list each SyncSource in ContribSource.
	ContribSource []uint32

	// Extension is an optional field which may be used by certain
	// payloads to transmit extra information. The RTP specification
	// discourages the use of Extension. Instead it recommendeds to
	// store extra information in leading bytes of the payload.
