This is an Java library transplanted from official Opus codec. With this library, Opus format audio can be operated in an easy way, including encoding WAV files to Opus and decoding Opus to WAV.

README

Welcome to the Opus demo for Linux server.

Summary

The is a demo on how to use Opus codec for Linux server. It can encode an opus file to a memory buffer and decode the buffer to an opus file.

Getting started

• pre-requisites

1. JDK v1.7 or higher
2. Eclipse

• Summary of set up:

1. Get the source code.[Git] (https://bitbucket.org/louisyoung/opus_linux.git)
2. Open it in Eclipse.
3. Compile and run.

Usage

OpusTool tool = new OpusTool();
String fin = "xxx", fout = "xxx";
ByteBuffer buf = tool.decode(fin, null);
..dosomething(buf)... //modify the PCM data if you want to
tool.encode(buf, fout, null);    
tool.releaseByteBuffer(buf);//free memory

Hints

1. top.oply.opuslib.OpusTool contains the basic codec functions.
2. If Ubuntu 64 bit server, the native library libopusTool.so under the folder "libs" can be used directly.
3. Compiling Native code is easy, just go to "\src\jni", and issue command "make". Then copy libopusTool.so to "libs".
