Types

type Decoder

type Decoder struct {
	BitDepth     int
	SampleRate   int
	ChannelCount int
	// contains filtered or unexported fields
}

Decoder is a RTP/LPCM decoder.

func (*Decoder) Decode

func (d *Decoder) Decode(pkt *rtp.Packet) ([]byte, time.Duration, error)

Decode decodes audio samples from a RTP packet. It returns audio samples and PTS of the first sample.

func (*Decoder) Init

func (d *Decoder) Init()

Init initializes the decoder.

type Encoder

type Encoder struct {
	// payload type of packets.
	PayloadType uint8

	// SSRC of packets (optional).
	// It defaults to a random value.
	SSRC *uint32

	// initial sequence number of packets (optional).
	// It defaults to a random value.
	InitialSequenceNumber *uint16

	// initial timestamp of packets (optional).
	// It defaults to a random value.
	InitialTimestamp *uint32

	// maximum size of packet payloads (optional).
	// It defaults to 1460.
	PayloadMaxSize int

	BitDepth     int
	SampleRate   int
	ChannelCount int
	// contains filtered or unexported fields
}

Encoder is a RTP/LPCM encoder.

func (*Encoder) Encode

func (e *Encoder) Encode(samples []byte, pts time.Duration) ([]*rtp.Packet, error)

Encode encodes audio samples into RTP packets.

func (*Encoder) Init

func (e *Encoder) Init()

Init initializes the encoder.
