Types

type OggStream

type OggStream struct {
	SampleRate uint
	Channels   uint
	Bitrate    uint
	FrameSize  float32
	Complexity uint
	// contains filtered or unexported fields
}

OggStream is an encoder that takes audio samples and encodes them using the Opus audio codec into an Ogg container, using the given settings.

func (*OggStream) Decode

func (s *OggStream) Decode(oggBytes []byte) ([]byte, error)

func (*OggStream) Encode

func (s *OggStream) Encode(audio []int16) ([]byte, error)

Encode takes an array of int16 PCM samples and encodes them into the Ogg container, returning any bytes generated by doing so (could be zero if a page flush is not triggered by the encode).

func (*OggStream) EncodeBytes

func (s *OggStream) EncodeBytes(audio []byte) ([]byte, error)

EncodeBytes takes a byte array of little-endian int16 PCM samples and encodes them into the Ogg container, returning any bytes generated by doing so (could be zero if a page flush is not triggered by the encode).

func (*OggStream) Flush

func (s *OggStream) Flush() []byte

Flush attempts to flush any possible completed pages from the Ogg container if data was submitted that didn't generate new page output.
