ffmpeg为android.error构建：./ obj / local / arm64-v8a / libavcodec.so：错误添加符号：文件格式错误

Question

Android.mk：

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)
LOCAL_MODULE := avcodec
LOCAL_SRC_FILES := libavcodec.so
include $(PREBUILT_SHARED_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE := avdevice
LOCAL_SRC_FILES := libavdevice.so
include $(PREBUILT_SHARED_LIBRARY)


include $(CLEAR_VARS)
LOCAL_MODULE := avfilter
LOCAL_SRC_FILES := libavfilter.so
include $(PREBUILT_SHARED_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE := avformat
LOCAL_SRC_FILES := libavformat.so
include $(PREBUILT_SHARED_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE := avutil
LOCAL_SRC_FILES := libavutil.so
include $(PREBUILT_SHARED_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE := swresample
LOCAL_SRC_FILES := libswresample.so
include $(PREBUILT_SHARED_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE := swscale
LOCAL_SRC_FILES := libswscale.so
include $(PREBUILT_SHARED_LIBRARY)


include $(CLEAR_VARS)
LOCAL_MODULE := ffmpeg_main
LOCAL_SRC_FILES := com_piyingke_app_common_ffmpeg_FFmpegUtil.c \
                   com_piyingke_app_common_ffmpeg_FFmpegUtil.h
LOCAL_C_INCLUDES += $(LOCAL_PATH)/include
LOCAL_LDLIBS := -llog -lz
LOCAL_SHARED_LIBRARIES := avcodec avdevice avfilter avformat avutil  swresample swscale
include $(BUILD_SHARED_LIBRARY)

而且我得到一个错误：

./obj/local/arm64-v8a/libavcodec.so：添加符号时出错：格式错误的文件

clang ++：错误：链接器命令失败，退出代码为1（使用-v查看调用）

制作：*** [obj / local / arm64-v8a / libffmpeg_main.so]错误1

我该怎么办？谁可以帮助我。

您有Application.mk吗？

您应该只为预构建文件运行构建。

像这样 ：

APP_ABI:=armeabi-v7a
