Types

type Decoder

type Decoder struct {
	sync.Mutex

	SampleRate int32
	Channels   int32
	// contains filtered or unexported fields
}

Decoder implements an OggVorbis decoder.

func New

func New(log *log.Entry, r librespot.SizedReadAtSeeker, meta *audio.MetadataPage, gain float32) (*Decoder, error)

New creates and initialises a new OggVorbis decoder for the provided bytestream.

func (*Decoder) Close

func (d *Decoder) Close()

Close stops and finalizes the decoding process, releases the allocated resources. Puts the decoder into an unrecoverable state.

func (*Decoder) PositionMs

func (d *Decoder) PositionMs() int64

func (*Decoder) Read

func (d *Decoder) Read(p []float32) (n int, err error)

func (*Decoder) SetPositionMs

func (d *Decoder) SetPositionMs(pos int64) (err error)

type Info

type Info struct {
	Channels   int32
	SampleRate int32
	Comments   []string
	Vendor     string
}

Info represents basic information about the audio in a Vorbis bitstream.
