【问题描述】：

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)

我得到一个错误：

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

clang++：错误：链接器命令失败，退出代码为 1（使用 -v 查看调用）

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

我该怎么办？谁能帮帮我。

【问题讨论】：

您是如何构建共享库的，例如 libavcodec.so ？您为哪种 CPU 架构编译了它们？我突然想到你没有正确的so文件。

标签： android ffmpeg

【解决方案1】：

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
