x264编译-2、集成x264库

川长思鸟来 2022-05-26 12:19 356阅读 0赞

1、编写Android.mk

#x264
    include $(CLEAR_VARS)
    LOCAL_MODULE    := x264
    LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/x264/include
    LOCAL_SRC_FILES := libs/libx264.a
    $(info $(LOCAL_SRC_FILES))
    include $(PREBUILT_STATIC_LIBRARY)

2、编写Application.mk

APP_ABI :=  armeabi
    APP_PLATFORM := android-19
    APP_STL := gnustl_static

3、遇到的坑

1、报错

    **** Build Finished ****

错误原因：在使用x264头文件前需要引入\#include

#include <stdint.h>
    #include "x264/include/x264.h"

错误位置：

APP_PLATFORM := android-9

解决方法：  
在Application.mk使用

APP_PLATFORM := android-19
