NDK 编译 SPEEX
原文地址：http://www.badlogicgames.com/wordpress/?p=1726&cpage=1#comment-109782
下载最新的SPEEX源代码，我的是1.21RC1
1 创建一个 jni目录，将libspeex与include放在jni目录下,即$jni/libspeex ,$jni/include
2 新建Android.mk
LOCAL_PATH := $(call my-dir) include $(CLEAR_VARS) LOCAL_MODULE := libspeex LOCAL_CFLAGS = -DFIXED_POINT -DUSE_KISS_FFT -DEXPORT="" -UHAVE_CONFIG_H LOCAL_C_INCLUDES := $(LOCAL_PATH)/include LOCAL_SRC_FILES := \ ./libspeex/bits.c \ ./libspeex/buffer.c \ ./libspeex/cb_search.c \ ./libspeex/exc_10_16_table.c \ ./libspeex/exc_10_32_table.c \ ./libspeex/exc_20_32_table.c \ ./libspeex/exc_5_256_table.c \ ./libspeex/exc_5_64_table.c \ ./libspeex/exc_8_128_table.c \ ./libspeex/fftwrap.c \ ./libspeex/filterbank.c \ ./libspeex/filters.c \ ./libspeex/gain_table.c \ ./libspeex/gain_table_lbr.c \ ./libspeex/hexc_10_32_table.c \ ./libspeex/hexc_table.c \ ./libspeex/high_lsp_tables.c \ ./libspeex/jitter.c \ ./libspeex/kiss_fft.c \ ./libspeex/kiss_fftr.c \ ./libspeex/lpc.c \ ./libspeex/lsp.c \ ./libspeex/lsp_tables_nb.c \ ./libspeex/ltp.c \ ./libspeex/mdf.c \ ./libspeex/modes.c \ ./libspeex/modes_wb.c \ ./libspeex/nb_celp.c \ ./libspeex/preprocess.c \ ./libspeex/quant_lsp.c \ ./libspeex/resample.c \ ./libspeex/sb_celp.c \ ./libspeex/scal.c \ ./libspeex/smallft.c \ ./libspeex/speex.c \ ./libspeex/speex_callbacks.c \ ./libspeex/speex_header.c \ ./libspeex/stereo.c \ ./libspeex/vbr.c \ ./libspeex/vq.c \ ./libspeex/window.c include $(BUILD_SHARED_LIBRARY)
3 jni目录下新建Application.mk
APP_ABI := armeabi armeabi-v7a
4 在jni/include/speex 目录下 将speex_config_type.h修改为如下
#ifndef __SPEEX_TYPES_H__ #define __SPEEX_TYPES_H__ typedef short spx_int16_t; typedef unsigned short spx_uint16_t; typedef int spx_int32_t; typedef unsigned int spx_uint32_t; #endif
5 然后在shell终端中到你的jni目录下，运行ndk-build，就可以开始编译了
6 然后就可以看到下图，生成了我们要的libspeex.so啦
7 写一个jni包裹文件，去调用编码和解码函数
8 最后享受吧。。。
这个大牛还上传了自己的工程，在这里下载
I zipped up my jni folder, you can download it here. Just fire up your shell, make sure your NDK is in your $PATH and ndk-build the shit out of it. Enjoy.
