利用ffmpeg和SDL实现一个跨android版本的音视频播放器

1:从 http://www.libsdl.org/tmp/下载SDL for android 版本（我下载的是 SDL-1.3.tar.gz ） 
2:从 https://github.com/havlenapetr/FFMpeg下载 havlenapetr 的ffmpeg for android版本。 
3:把你下载的SDL for android版本解压到本地目录,解压到本地. 
4:解压后的根目录下面有一个android-project工程,在jni目录下面新建一个SDL目录，把根目录下面的src目录，include目录和Android.mk拷贝到新建里的SDL目录下面 
5:把ffmpeg for android 工程下jni目录的libffmpeg拷贝到android-project的jni目录下 
6: http://dranger.com/ffmpeg/下载tutorial08代码并把文件放在jni的src目录下 
8:编写tutorial08的mk文件 

 LOCAL_PATH := $(call my-dir)

 include $(CLEAR_VARS)

 LOCAL_MODULE := main

 SDL_PATH := ../SDL

 LOCAL_C_INCLUDES += $(LOCAL_PATH)/$(SDL_PATH)/include \
             $(LOCAL_PATH)/../libffmpeg \

 # Add your application source files here...
 LOCAL_SRC_FILES := $(SDL_PATH)/src/main/android/SDL_android_main.cpp \
     tutorial08.c

 LOCAL_CFLAGS += -DGL_GLEXT_PROTOTYPES
 LOCAL_SHARED_LIBRARIES := SDL
 LOCAL_STATIC_LIBRARIES := libavformat libavcodec libavutil libpostproc libswscale

 LOCAL_LDLIBS := -ldl -lGLESv2 -llog

 include $(BUILD_SHARED_LIBRARY)

9:SDLActivity中load so 

 // Load the .so
    static {
        System.loadLibrary("SDL");
        //System.loadLibrary("SDL_image");
        //System.loadLibrary("SDL_mixer");
        //System.loadLibrary("SDL_ttf");
        System.loadLibrary("main");
    }

10:改写nativeInit方法 

 // Runs SDL_main()
     String avPath = Environment.getExternalStorageDirectory()+File.separator+"DancingQueen.mp4";
       SDLActivity.nativeInit(avPath);

       //Log.v("SDL", "SDL thread terminated");

11:进入到android-project项目根目录,ndk-build 耐心等待一会就可以编译出两个库libSDL.so和libmain.so 



运行你的android-project项目播放你的视频吧.
