Android本地視頻播放器開發--SDL編譯

編輯：關於Android編程

其實1.3以後的版本就添加了android的支持，所以下載完源碼後，在SDL目錄下創建一個jni的目錄，然後將原先SDL目錄下面的文件以及文件夾都拷貝到jni目錄下面，在jni目錄下面我們會看見一個android.mk的文件,這就是官方給我們編寫的編譯文件，由於手機基本上都是使用的arm編譯器，所以我在裡面添加了LOCAL_ARM_MODE=arm，模塊的編譯使用arm編譯器來編譯，具體的內容如下:
[cpp] ###########################  
#  
# SDL shared library  
#  
###########################  
 
include $(CLEAR_VARS) 
 
LOCAL_MODULE := SDL2 
LOCAL_ARM_MODE=arm 
LOCAL_C_INCLUDES := $(LOCAL_PATH)/include 
 
LOCAL_SRC_FILES := \ 
        $(subst $(LOCAL_PATH)/,, \ 
        $(wildcard $(LOCAL_PATH)/src/*.c) \

        $(wildcard $(LOCAL_PATH)/src/video/android/*.c)) 
 
LOCAL_CFLAGS += -DGL_GLEXT_PROTOTYPES 
LOCAL_LDLIBS := -ldl -lGLESv1_CM -lGLESv2 -llog 
 
include $(BUILD_SHARED_LIBRARY) 

###########################

include $(CLEAR_VARS)

LOCAL_MODULE := SDL2
LOCAL_ARM_MODE=arm
LOCAL_C_INCLUDES := $(LOCAL_PATH)/include

LOCAL_SRC_FILES := \
        $(subst $(LOCAL_PATH)/,, \
        $(wildcard $(LOCAL_PATH)/src/*.c) \

LOCAL_CFLAGS += -DGL_GLEXT_PROTOTYPES
LOCAL_LDLIBS := -ldl -lGLESv1_CM -lGLESv2 -llog

include $(BUILD_SHARED_LIBRARY)三、如果直接編譯的話會提示如下錯誤
[cpp]  /home/SDL/jni/src/core/android/SDL_android.cpp:30:21: fatal error: EGL/egl.h: No such file or directory 

/home/SDL/jni/src/core/android/SDL_android.cpp:30:21: fatal error: EGL/egl.h: No such file or directory
查看EGL的支持是在2.3版本以上，所以我們需要添加平台的支持，所以需要在jni目錄下面創建一個Application.mk文件來指定編譯平台，內容如下:
[cpp]  APP_ABI := armeabi 
APP_PLATFORM := android-9 

APP_ABI := armeabi
APP_PLATFORM := android-9四、在jni目錄終端下運行ndk-build，就會編譯出libSDL2.so，編譯過程如下:

編譯出sdl庫後，我們就可以調用它的相關函數來實現我們的功能了。
