Types

type Depacketizer added in v1.1.0 

type Depacketizer interface {
	Unmarshal(packet *Packet) ([]byte, error)
}

Depacketizer depacketizes a RTP payload, removing any RTP specific data from the payload

type Packet struct {
	Raw              []byte
	Version          uint8
	Padding          bool
	Extension        bool
	Marker           bool
	PayloadOffset    int
	PayloadType      uint8
	SequenceNumber   uint16
	Timestamp        uint32
	SSRC             uint32
	CSRC             []uint32
	ExtensionProfile uint16
	ExtensionPayload []byte
	Payload          []byte
}

Packet represents an RTP Packet RTP is a network protocol for delivering audio and video over IP networks.

func (*Packet) Marshal 

func (p *Packet) Marshal() ([]byte, error)

Marshal returns a raw RTP packet for the instance it is called upon

func (*Packet) Unmarshal 

func (p *Packet) Unmarshal(rawPacket []byte) error

Unmarshal parses the passed byte slice and stores the result in the Packet this method is called upon

type Packetizer 

type Packetizer interface {
	Packetize(payload []byte, samples uint32) []*Packet
}

Packetizer packetizes a payload

func NewPacketizer 

func NewPacketizer(mtu int, pt uint8, ssrc uint32, payloader Payloader, sequencer Sequencer, clockRate uint32) Packetizer

NewPacketizer returns a new instance of a Packetizer for a specific payloader

type Payloader 

type Payloader interface {
	Payload(mtu int, payload []byte) [][]byte
}

Payloader payloads a byte array for use as rtp.Packet payloads

type Sequencer 

type Sequencer interface {
	NextSequenceNumber() uint16
	RollOverCount() uint64
}

Sequencer generates sequential sequence numbers for building RTP packets

func NewFixedSequencer 

func NewFixedSequencer(s uint16) Sequencer

NewFixedSequencer returns a new sequencer starting from a specific sequence number

func NewRandomSequencer 

func NewRandomSequencer() Sequencer

NewRandomSequencer returns a new sequencer starting from a random sequence number
