AndroidStudio集成FFMPEG

一、FFMPEG源码编译

 

 

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：

 

1. cmake_minimum_required(VERSION 3.4.1)

2. add_library( native-lib

3. SHARED

4. src/main/cpp/native-lib.cpp

5. )

6.  

7. include_directories(libs/include)

8. set(DIR ../../../../libs)

9. MESSAGE("打印")

10. MESSAGE("路径 " ${DIR})

11. add_library(avcodec-56

12. SHARED

13. IMPORTED)

14. set_target_properties(avcodec-56

15. PROPERTIES IMPORTED_LOCATION

16. ${DIR}/armeabi/libavcodec-56.so)

17. add_library(avdevice-56

18. SHARED

19. IMPORTED)

20. set_target_properties(avdevice-56

21. PROPERTIES IMPORTED_LOCATION

22. ${DIR}/armeabi/libavdevice-56.so)

23. add_library(avformat-56

24. SHARED

25. IMPORTED)

26. set_target_properties(avformat-56

27. PROPERTIES IMPORTED_LOCATION

28. ${DIR}/armeabi/libavformat-56.so)

29. add_library(avutil-54

30. SHARED

31. IMPORTED)

32. set_target_properties(avutil-54

33. PROPERTIES IMPORTED_LOCATION

34. ${DIR}/armeabi/libavutil-54.so)

35. add_library(swresample-1

36. SHARED

37. IMPORTED)

38. set_target_properties(swresample-1

39. PROPERTIES IMPORTED_LOCATION

40. ${DIR}/armeabi/libswresample-1.so)

41. add_library(swscale-3

42. SHARED

43. IMPORTED)

44. set_target_properties(swscale-3

45. PROPERTIES IMPORTED_LOCATION

46. ${DIR}/armeabi/libswscale-3.so)

47. add_library(avfilter-5

48. SHARED

49. IMPORTED)

50. set_target_properties(avfilter-5

51. PROPERTIES IMPORTED_LOCATION

52. ${DIR}/armeabi/libavfilter-5.so)

53.  

54. find_library( log-lib

55. log )

56. target_link_libraries( native-lib

57. avcodec-56

58. avdevice-56

59. avformat-56

60. avutil-54

61. swresample-1

62. swscale-3

63. -landroid # Add this.

64. ${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

 

1. //

2. // Created by ygdx_lk on 17/11/1.

3. //

4.  

5. #ifndef FFMPEG_NATIVE_LIB_H

6. #define FFMPEG_NATIVE_LIB_H

7. #include <jni.h>

8. #include <string>

9. #include <android/log.h>

10.  

11. extern "C" {

12. //编码

13. #include "libavcodec/avcodec.h"

14. //封装格式处理

15. #include "libavformat/avformat.h"

16. //像素处理

17. #include "libswscale/swscale.h"

18. #include <android/native_window_jni.h>

19. #include <unistd.h>

20. JNIEXPORT jstring JNICALL Java_com_test_ffmpeg_MainActivity_stringFromJNI(JNIEnv *env, jobject /* this */);

21. }

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

23. #define LOGE(FORMAT, ...) __android_log_print(ANDROID_LOG_ERROR,"jason",FORMAT,##__VA_ARGS__);

24.  
25.  

26. #endif //FFMPEG_NATIVE_LIB_H

 

 

native-lib.cpp

 

1. #include "native-lib.h"

2. jstring Java_com_test_ffmpeg_MainActivity_stringFromJNI(JNIEnv *env, jobject /* this */) {

3. std::string hello = "Hello from C++";

4. av_register_all();

5. return env->NewStringUTF(hello.c_str());

6. }

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。
