完美解决个人微信音频amr文件与mp3格式互转 完美解决个人微信音频amr文件与mp3格式互转 1、安装gcc ffmpeg wget http://downloads.sourceforge.net/lame/lame-3.100.tar.gz tar -zxvf lame-3.100.tar.gz cd lame-3.100 ./configure --prefix=/usr/local make && make install ln -s /usr/local/lib/libmp3lame.so.0.0.0 /usr/lib64/libmp3lame.so.0 wget http://ffmpeg.org/releases/ffmpeg-3.4.1.tar.bz2 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 # 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 RED="$(tput setaf 1 2>/dev/null || echo '\e[0;31m')" GREEN="$(tput setaf 2 2>/dev/null || echo '\e[0;32m')" YELLOW="$(tput setaf 3 2>/dev/null || echo '\e[0;33m')" WHITE="$(tput setaf 7 2>/dev/null || echo '\e[0;37m')" RESET="$(tput sgr 0 2>/dev/null || echo '\e[0m')" # Main cur_dir=$(cd `dirname $0`; pwd) if [ ! -r "$cur_dir/silk/encoder" ]; then echo -e "${WHITE}[Notice]${RESET} Silk v3 Encoder is not found, compile it." cd $cur_dir/silk make && make encoder [ ! -r "$cur_dir/silk/encoder" ]&&echo -e "${RED}[Error]${RESET} Silk v3 Encoder Compile False, Please Check Your System For GCC."&&exit echo -e "${WHITE}========= Silk v3 Encoder Compile Finish =========${RESET}" fi cd $cur_dir while [ $3 ]; do [[ ! -z "$(pidof ffmpeg)" ]]&&echo -e "${RED}[Error]${RESET} ffmpeg is occupied by another application, please check it."&&exit [ ! -d "$1" ]&&echo -e "${RED}[Error]${RESET} Input folder not found, please check it."&&exit TOTAL=$(ls $1|wc -l) [ ! -d "$2" ]&&mkdir "$2"&&echo -e "${WHITE}[Notice]${RESET} Output folder not found, create it."
