Interface StreamDecoder

All Superinterfaces:

Decoder

public interface StreamDecoder
extends Decoder

This interface may be used to decode the specified source file or stream to MP3 with only one call or progressively by chunks.

A decoding process must start decoding MP3 headers, the method decodeHeaders() must be called first.

LAMEOnJStdDecoder.createStreamDecoder(String), LAMEOnJStdDecoder.createStreamDecoder(InputStream)

Method Summary

void	decode(java.io.OutputStream wavStream) Decodes the MP3 input source to WAV saving to the specified stream.
void	decode(java.lang.String wavFile) Decodes the MP3 input source to WAV saving to the specified file.
PCMFrame	decodeFrame() Decodes source MP3 data to build one PCM frame.
mp3data_struct	decodeHeaders() Decodes source MP3 data until MP3 header info is obtained.
java.io.InputStream	getSourceInputStream() Returns the input stream used to decode.
