cocos2dx跨平台直播实例-ffmpeg-android篇

一、环境

windows10(mac的虚拟机)

cocos2dx-3.13.1

android(adt-bundle-window-86\_64-20140702)

ffmpeg-3.0

ndk(android-ndk-r10c)

好了，其他的比如jdk什么的就不说了。

二、项目配置

大家想要在android上运行cocos2dx的项目要先配置好cococs2dx的android环境。这个有[传送门][Link 1]。

哦，还有，我的环境是在eclipse上配置的（不好意思），没用过AndroidStudio，不好意思，不过大家可以看eclipse，懂得eclipse和AndroidStudio的就可以根据eclipse配置自己的AndroidStudio了。

下面的配置说明是根据大家配置好了cocos2dx运行的环境之后说的，cocos2dx的配置我就不再啰嗦了。

现在我们的cocos2dx是用的我的上一篇[cocos2dx跨平台直播实例-ffmpeg-ios篇][cocos2dx_-ffmpeg-ios]写过的项目。

好了，把项目Import进eclipse里，现在大家配置好了cocos2dx的环境，运行一下，肯定是报错的，因为我们之前写的LiveVideo需要ffmpeg库，而我们上一篇中配置的ffmpeg库的环境只是ios或者mac项目的，android里面并没有这样的环境！！

所以，接下来我们要配置ffmpeg在cococs2dx-android的项目上的环境。

1.ffmpeg在android用的库的编译

[传送门][Link 2]。这篇文章里的编译环境是在mac下的，linux下也可以，所以windows的同学还得建个linux或者mac的虚拟机才行。。。。

2.ffmpeg库在andorid上的配置

ffmpeg编译好之后，把include和lib文件夹复制到android项目的jni下面。

如图：

![Center][]

之后，

修改Android.mk文件

LOCAL_PATH := $(call my-dir)
    
    include $(CLEAR_VARS)
    
    LOCAL_MODULE:= libavcodec
    
    LOCAL_SRC_FILES:= lib/libavcodec-57.so
    
    LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include
    
    include $(PREBUILT_SHARED_LIBRARY)
     
    
    include $(CLEAR_VARS)
    
    LOCAL_MODULE:= libavformat
    
    LOCAL_SRC_FILES:= lib/libavformat-57.so
    
    LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include
    
    include $(PREBUILT_SHARED_LIBRARY)
    
     
    
    include $(CLEAR_VARS)
    
    LOCAL_MODULE:= libswscale
    
    LOCAL_SRC_FILES:= lib/libswscale-4.so
    
    LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include
    
    include $(PREBUILT_SHARED_LIBRARY)
    
     
    
    include $(CLEAR_VARS)
    
    LOCAL_MODULE:= libavutil
    
    LOCAL_SRC_FILES:= lib/libavutil-55.so
    
    LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include
    
    include $(PREBUILT_SHARED_LIBRARY)
    
     
    
    include $(CLEAR_VARS)
    
    LOCAL_MODULE:= libavfilter
    
    LOCAL_SRC_FILES:= lib/libavfilter-6.so
    
    LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include
    
    include $(PREBUILT_SHARED_LIBRARY)
    
     
    
    include $(CLEAR_VARS)
    
    LOCAL_MODULE:= libswresample
    
    LOCAL_SRC_FILES:= lib/libswresample-2.so
    
    LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include
    
    include $(PREBUILT_SHARED_LIBRARY)
    
    include $(CLEAR_VARS)
    
    $(call import-add-path,$(LOCAL_PATH)/../../cocos2d)
    $(call import-add-path,$(LOCAL_PATH)/../../cocos2d/external)
    $(call import-add-path,$(LOCAL_PATH)/../../cocos2d/cocos)
    $(call import-add-path,$(LOCAL_PATH)/../../cocos2d/cocos/audio/include)
    
    LOCAL_MODULE := MyGame_shared
    
    LOCAL_MODULE_FILENAME := libMyGame
    
    LOCAL_SRC_FILES := hellocpp/main.cpp \
    				   ../../Classes/LiveVideo.cpp \
                       ../../Classes/AppDelegate.cpp \
                       ../../Classes/HelloWorldScene.cpp
    
    LOCAL_C_INCLUDES := $(LOCAL_PATH)/../../Classes
    LOCAL_C_INCLUDES += $(LOCAL_PATH)/include
    LOCAL_SHARED_LIBRARIES:=libavcodec libavfilter libavformat libavutil libswscale libswresample
    
    # _COCOS_HEADER_ANDROID_BEGIN
    # _COCOS_HEADER_ANDROID_END
    
    
    LOCAL_STATIC_LIBRARIES := cocos2dx_static
    
    # _COCOS_LIB_ANDROID_BEGIN
    # _COCOS_LIB_ANDROID_END
    
    include $(BUILD_SHARED_LIBRARY)
    
    $(call import-module,.)
    
    # _COCOS_LIB_IMPORT_ANDROID_BEGIN
    # _COCOS_LIB_IMPORT_ANDROID_END

用上面的内容替换掉Android.mk里的内容。

然后，Application.mk文件：

加上这句

![Center 1][]

编译Project-Clean。

![Center 2][]

完成，等待编译结束。。。。。。。

最后，如果大家配置的时候出现问题可以留言或者下载项目[https://github.com/zhu12345618/ffmeg\_android\_test][https_github.com_zhu12345618_ffmeg_android_test]

还有一个，就是iod和android都可以运行的项目[https://github.com/zhu12345618/ffmeg\_android\_test][https_github.com_zhu12345618_ffmeg_android_test]
