const ( IN_MAX_BUFFER_SIZE = 16384 OUT_MAX_BUFFER_SIZE = 32768 )
Variables ¶
var EOF = errors.New("EOF")
Functions ¶
func ExitMpg123 ¶
func ExitMpg123()
func GetEncodingBitsPerSample ¶
int mpg123_encsize ( int encoding )
func InitializeMpg123 ¶
func InitializeMpg123()
func SupportedDecoders ¶
func SupportedDecoders() []string
const char** mpg123_supported_decoders(void)
Types ¶
type Decoder ¶
Contains a handle for and mpg123 decoder instance
func NewDecoder ¶
NewDecoder creates a new mpg123 decoder instance
func (*Decoder) CurrentDecoder ¶
const char* mpg123_current_decoder(mpg123_handle *mh)
func (*Decoder) DecodeSamples ¶
func (*Decoder) DecoderReader ¶
func (d *Decoder) DecoderReader( src io.Reader, fps int, channels int, encoding int, ) *DecoderReader
DecoderReader gives you an io.Reader for streaming-decoding. It performs a combination of Feed and Read, and relies on you to first call OpenFeed before invoking DecoderReader.Read.
func (*Decoder) FormatAll ¶
func (d *Decoder) FormatAll()
FromatAll enables all decoder output formats (this is the default setting)
func (*Decoder) FormatNone ¶
func (d *Decoder) FormatNone()
FormatNone disables all decoder output formats (used to specifying supported formats)
func (*Decoder) GetLengthInPCMFrames ¶
off_t mpg123_length(mpg123_handle * mh)
func (*Decoder) MonoDecoderReader ¶
MonoDecoderReader is an alias that gives you an io.Reader for decoding a stream that is known to be mono-channeled.
func (*Decoder) ReadAudioFrames ¶
func (*Decoder) TellCurrentSample ¶
off_t mpg123_tell(mpg123_handle *mh)
type DecoderReader ¶
type DecoderReader struct {
// contains filtered or unexported fields
}
DecoderReader is the way to decode streaming MP3
func (DecoderReader) Nuke ¶
func (dr DecoderReader) Nuke()
Nuke kills our DecoderReader appropriately
func (*DecoderReader) Paranoid ¶
func (dr *DecoderReader) Paranoid() *DecoderReader
Paranoid mode shuts off the decoder on a non-EOF error (handy if your input is a duplex network stream).
