isdom / jspeex-util

java JNI 调用C实现.speex转换为.wav;使用场景：微信高清语音.speex解码为.wav

JSpeex-util 使用

功能介绍：PC端将.speex文件解码为*.wav文件

环境：

1. MAC OS 10.12.5/Linux ubuntu
2. Xcode
3. Gcc
4. JDK 1.8
5. speex 1.2.0

步骤：

1. 安装libspeex

从https://www.speex.org/downloads/下载speex-1.2.0.tar.gz

解压speex-1.2.0.tar.gz

cd pathto/speex-1.2.0 ./configure

    ...

    config.status: creating ti/speex_C55_test/Makefile
    config.status: creating ti/speex_C64_test/Makefile
    config.status: creating config.h
    config.status: executing depfiles commands
    config.status: executing libtool commands
    Type "make; make install" to compile and install Speex

sudo make install

    Making install in libspeex
     .././install-sh -c -d '/usr/local/lib'
     /bin/sh ../libtool   --mode=install /usr/bin/install -c   libspeex.la '/usr/local/lib'
    libtool: install: /usr/bin/install -c .libs/libspeex.1.dylib /usr/local/lib/libspeex.1.dylib
    libtool: install: (cd /usr/local/lib && { ln -s -f libspeex.1.dylib libspeex.dylib || { rm -f libspeex.dylib && ln -s libspeex.1.dylib libspeex.dylib; }; })
    libtool: install: /usr/bin/install -c .libs/libspeex.lai /usr/local/lib/libspeex.la
    libtool: install: /usr/bin/install -c .libs/libspeex.a /usr/local/lib/libspeex.a
    libtool: install: chmod 644 /usr/local/lib/libspeex.a
    libtool: install: ranlib /usr/local/lib/libspeex.a
    make[2]: Nothing to be done for `install-data-am'.
    Making install in include
    Making install in speex
    ...
    ...

2.打包

cd pathto/release

linux系统:

make -f makefile-linux
make -f makefile-linux install

mac系统:

make -f makefile-mac
make -f makefile-mac install

3.测试 SpeexUtils.decode("pathto/a.speex", "pathto/a-test.wav");

4.测试文件 ./resources/a.speex ./resources/b.speex

常见问题

1.linux 生成动态库时提示relocation R_X86_64_32 against `.rodata' can not be used when making a shared object;

由于系统是AMD64位的，所以需要在编译的时候添加 -fPIC 选项

解决方法:

例如:

gcc -c -fPIC head.c

or

g++ -c -fPIC head.cpp 生成head.o

g++ -fpic -shared -o libfun.so head.o

缺少动态连接库.so--cannot open shared object file: No such file or directory 总结下来主要有3种方法：

1. 用ln将需要的so文件链接到/usr/lib或者/lib这两个默认的目录下边

ln -s /where/you/install/lib/*.so /usr/lib
sudo ldconfig

2.修改LD_LIBRARY_PATH

export LD_LIBRARY_PATH=/where/you/install/lib:$LD_LIBRARY_PATH
sudo ldconfig

3.修改/etc/ld.so.conf，然后刷新

vim /etc/ld.so.conf
增加一行 include /where/you/install/lib

sudo ldconfig
