关于用ffmpeg转换音频文件amr格式为aac格式记录。包含java代码以及liunx安装

private void convertAmrToAac(File source, String target){
        String ffmpeg = configNameDao.getConfigValueByKey("ffmpeg");
        String command = ffmpeg + " -i " + source.getAbsolutePath() + " -c:a aac " + target;
        logger.info("execute:" + command);
        try {
            Runtime rt = Runtime.getRuntime();
            Process proc = rt.exec(command);
            int i = proc.waitFor();
            logger.info("Process waitFor 返回结果：{}", i);
        } catch (Throwable t) {
            t.printStackTrace();
            logger.info("命令执行失败");
        }
}
