AndroidStudio集成FFMPEG
1.新建android项目,勾选include C++ support
2.勾选Exceptions Support (-fexceptions)、Runtime Type Information Support (-frtti)
3.Finish后的项目目录
4.libs下创建armeabi目录,拷贝ffmpeg编译后的so文件到armeabi下,拷贝include文件到libs目录下
5.app下的build.gradle修改如下:
6.CMakeLists.txt修改如下:
-
cmake_minimum_required(VERSION 3.4.1)
-
add_library( native-lib
-
SHARED
-
src/main/cpp/native-lib.cpp
-
)
-
include_directories(libs/include)
-
set(DIR ../../../../libs)
-
MESSAGE("打印")
-
MESSAGE("路径 " ${DIR})
-
add_library(avcodec-56
-
SHARED
-
IMPORTED)
-
set_target_properties(avcodec-56
-
PROPERTIES IMPORTED_LOCATION
-
${DIR}/armeabi/libavcodec-56.so)
-
add_library(avdevice-56
-
SHARED
-
IMPORTED)
-
set_target_properties(avdevice-56
-
PROPERTIES IMPORTED_LOCATION
-
${DIR}/armeabi/libavdevice-56.so)
-
add_library(avformat-56
-
SHARED
-
IMPORTED)
-
set_target_properties(avformat-56
-
PROPERTIES IMPORTED_LOCATION
-
${DIR}/armeabi/libavformat-56.so)
-
add_library(avutil-54
-

-
add_library(avfilter-5
-
SHARED
-
IMPORTED)
-
set_target_properties(avfilter-5
-
PROPERTIES IMPORTED_LOCATION
-
${DIR}/armeabi/libavfilter-5.so)
-
find_library( log-lib
-
log )
-
target_link_libraries( native-lib
-
avcodec-56
-

-
avformat-56
-
avutil-54
-

-
swscale-3
-

-
${log-lib} )
7.cpp目录下新建native-lib.h头文件,native-lib.cpp是默认生成的
native-lib.h

}
-
#define LOGI(FORMAT, ...) __android_log_print(ANDROID_LOG_INFO,"jason",FORMAT,##__VA_ARGS__);
-

-
#endif //FFMPEG_NATIVE_LIB_H
native-lib.cpp
-
#include "native-lib.h"
-
jstring Java_com_test_ffmpeg_MainActivity_stringFromJNI(JNIEnv *env, jobject /* this */) {
-
std::string hello = "Hello from C++";
-
av_register_all();
-
return env->NewStringUTF(hello.c_str());
-
}
8.MainActivity中配置如下:
9.运行程序,如果可以正常运行,说明ffmpeg的配置已经ok。
