完美解决个人微信音频amr文件与mp3格式互转

tar -jxvf ffmpeg-3.4.1.tar.bz2

cd ffmpeg-3.4.1

./configure --prefix=/usr/local --pkg-config-flags=–static --enable-libmp3lame --disable-x86asm

make && make install

2、安装/silk-v3-decoder
 

cd /usr/local/soft

wget https://github.com/kn007/silk-v3-decoder/archive/master.zip

unzip master.zip

chmod -R +x /usr/local/soft/silk-v3-decoder-master/

silk-v3-decoder/converter.sh 微信amr文章文件路径名 mp3

3、改造一个encoder脚本，decoder已经有了不用改造了

converter-encoder.sh(请拷贝以下脚本放到silk-v3-decoder-master目录下)

#!/bin/bash

File: converter.sh

Date: August 19th, 2016

Time: 18:56:52 +0800

Author: kn007 <kn007@126.com>

Blog: https://kn007.net

Link: https://github.com/kn007/silk-v3-encoder

Usage: sh converter.sh silk_v3_file/input_folder output_format/output_folder flag(format)

Flag: not define ---- not define, convert a file

other value ---- format, convert a folder, batch conversion support

Requirement: gcc ffmpeg

Colors

GREEN=“$(tput setaf 2 2>/dev/null || echo ‘\e[0;32m’)”

YELLOW=“$(tput setaf 3 2>/dev/null || echo ‘\e[0;33m’)”

Main

cur_dir=$(cd dirname $0; pwd)

if [ ! -r “$cur_dir/silk/encoder” ]; then

make && make encoder

cd $cur_dir

while [ $3 ]; do

4、用java调用脚本
 

private static String silkv3Path=“/usr/local/soft/silk-v3-decoder-master/”;

/**

• 将amr转成mp3

• @param coderPath

• @param amrfilePath

*/

public static void converterDecoderMp3(String coderPath, String amrfilePath) {

if(StringUtils.isBlank(coderPath)){

coderPath = silkv3Path;

}

String decoderCmd = coderPath + "converter.sh " + amrfilePath;

exeCmd(decoderCmd);

}

/**

• 将mp3转成amr

• @param coderPath

• @param mp3filePath

*/

public static void converterEncoderAmr(String coderPath, String mp3filePath) {

if(StringUtils.isBlank(coderPath)){

coderPath = silkv3Path;

}

String encoderCmd= coderPath + "converter-encoder.sh " + mp3filePath;

exeCmd(encoderCmd);

}

private static void exeCmd(String commandStr) {

BufferedReader br = null;

try {

Process p = Runtime.getRuntime().exec(commandStr);

br = new BufferedReader(new InputStreamReader(p.getInputStream()));

String line = null;

StringBuilder sb = new StringBuilder();

while ((line = br.readLine()) != null) {

sb.append(line + “\n”);
