用.zip打开jar完成到libxuggle.dll（linux为.so)文件拷贝到你的jdk bin目录下

public void convertToMP3(File input, File output, int kbps) { //modify on your convenience// create a media readerIMediaReader mediaReader = ToolFactory.makeReader(input.getPath());// create a media writerIMediaWriter mediaWriter = ToolFactory.makeWriter(output.getPath(), mediaReader);// add a writer to the reader, to create the output filemediaReader.addListener(mediaWriter);// add a IMediaListner to the writer to change bit ratemediaWriter.addListener(new MediaListenerAdapter() {@Overridepublic void onAddStream(IAddStreamEvent event) {IStreamCoder streamCoder = event.getSource().getContainer().getStream(event.getStreamIndex()).getStreamCoder();streamCoder.setFlag(IStreamCoder.Flags.FLAG_QSCALE, false);streamCoder.setBitRate(kbps);streamCoder.setBitRateTolerance(0);}});// read and decode packets from the source file and// and dispatch decoded audio and video to the writerwhile (mediaReader.readPacket() == null);
}

 kbps ＝ 64 * 1000
