在Echoprint系列--编译中编译了源代码，这次将Echoprint移植到Android平台并測试识别歌曲功能。
一、编译库
1、环境准备
- Android NDK，我的是android-ndk-r10e
- 改动源代码，把src中的.cxx的文件重命名为.cpp。把src文件夹重命名为jni
- Boost源代码。在PC上编译的时候也安装boost的，我的时boost_1_58_0，复制到jni文件夹
2、编写编译配置文件
- 打开源代码中的main.cpp，看到核心部分就是
codegen_response_t *codegen_file(char* filename, int start_offset, int duration, int tag)
Notes about libcodegen: Code generation takes a buffer of floating point PCM data sampled at 11025 Hz and mono. Codegen * pCodegen = new Codegen(const float* pcm, uint numSamples, int start_offset); pcm: a buffer of floats, mono, 11025 Hz numSamples: the number of samples start_offset: creates a hint to the server on where the sample is taken from in the original file if known string code = pCodegen->getCodeString(); The code string is just a base64 encoding of a zlib compression of the original code string, which is a hex encoded series of ASCII numbers. See API/fp.py in echoprint-server for decoding help. You only need to query for 20 seconds of audio to get a result.打开Android Studio创建一个Android项目。新建一个文件名称为Codegen.java，在里面写入
native String codegen(float data[], int numSamples);这次在移动设备上识别的是通过麦克风录音。所以參数不一样的，使用javah将Codegen.java生成头文件
zhangjiedeMacBook-Pro:java zhangjie$ javah -classpath . -jni cc.jwzhangjie.echoprintandroid.Codegen
在终端的当前文件夹会生成一个cc_jwzhangjie_echoprintandroid_Codegen.h
- 在libs同文件夹创建一个jni文件夹，把cc_jwzhangjie_echoprintandroid_Codegen.h拷贝进去，然后创建cc_jwzhangjie_echoprintandroid_Codegen.cpp文件，内容例如以下：
#include <string.h>
#include "cc_jwzhangjie_echoprintandroid_Codegen.h"
#include "Codegen.h"
JNIEXPORT jstring JNICALL Java_cc_jwzhangjie_echoprintandroid_Codegen_codegen
(JNIEnv *env, jobject thiz, jfloatArray pcmData, jint numSamples){
float *data = (float *)env->GetFloatArrayElements(pcmData, 0);
Codegen c = Codegen(data, (unsigned int)numSamples, 0);
const char *code = c.getCodeString().c_str();
env->ReleaseFloatArrayElements(pcmData, data, 0);
return env->NewStringUTF(code);
}
-
在jni文件夹以下创建Android.mk和Application.mk。内容分别例如以下：
LOCAL_PATH := $(call my-dir) include $(CLEAR_VARS) LOCAL_MODULE := echoprint-jni LOCAL_SRC_FILES := cc_jwzhangjie_echoprintandroid_Codegen.cpp Codegen.cpp Whitening.cpp SubbandAnalysis.cpp MatrixUtility.cpp Fingerprint.cpp Base64.cpp AudioStreamInput.cpp AudioBufferInput.cpp LOCAL_LDLIBS := -llog -lz LOCAL_C_INCLUDES := . ./boost_1_58_0 LOCAL_CPPFLAGS += -fexceptions include $(BUILD_SHARED_LIBRARY)
Application.mk
APP_STL := gnustl_static APP_ABI := armeabi armeabi-v7a
- 把之前命名jni文件中面的内容复制到项目中的jni以下，在终端下输入：
zhangjiedeMacBook-Pro:jni zhangjie$ ndk-build
[armeabi] Compile++ thumb: echoprint-jni <= cc_jwzhangjie_echoprintandroid_Codegen.cpp

[armeabi-v7a] SharedLibrary : libechoprint-jni.so
[armeabi-v7a] Install : libechoprint-jni.so => libs/armeabi-v7a/libechoprint-jni.so
如今成功编译出libechoprint-jni.so文件
二、调用库
Codegen.java这个类用来调用so将ccm生成code
package cc.jwzhangjie.echoprintandroid;
/**
* Created by zhangjie on 15/6/9.
*/
public class Codegen {
private final float normalizingValue = Short.MAX_VALUE;
native String codegen(float data[], int numSamples);
static
{
System.loadLibrary("echoprint-jni");
}
/**
* Invoke the echoprint native library and generate the fingerprint code.<br>
* Echoprint REQUIRES PCM encoded audio with the following parameters:<br>
* Frequency: 11025 khz<br>
* Data: MONO - PCM enconded float array
*
* @param data PCM encoded data as floats [-1, 1]
* @param numSamples number of PCM samples at 11025 KHz
* @return The generated fingerprint as a compressed - base64 string.
*/
public String generate(float data[], int numSamples)
{
return codegen(data, numSamples);
}
/**
* Invoke the echoprint native library and generate the fingerprint code.<br>
* Since echoprint requires the audio data to be an array of floats in the<br>
* range [-1, 1] this method will normalize the data array transforming the<br>
* 16 bit signed shorts into floats.
*
* @param data PCM encoded data as shorts
* @param numSamples number of PCM samples at 11025 KHz
* @return The generated fingerprint as a compressed - base64 string.
*/
public String generate(short data[], int numSamples)
{
// echoprint expects data as floats, which is the native value for
// core audio data, and I guess ffmpeg
// Android records data as 16 bit shorts, so we need to normalize the
// data before sending it to echoprint
float normalizeAudioData[] = new float[numSamples];
for (int i = 0; i < numSamples - 1; i++)
normalizeAudioData[i] = data[i] / normalizingValue;
return this.codegen(normalizeAudioData, numSamples);
}
}
