jspeex java_GitHub - guoguo11/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：

MAC OS 10.12.5/Linux ubuntu

Xcode

Gcc

JDK 1.8

speex 1.2.0

步骤：

安装libspeex

解压speex-1.2.0.tar.gz

cd pathto/speex-1.2.0

./configure

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

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：

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
