linux - 无法将应用程序与 libavcodec 链接

Question

我正在尝试使用 ffmpeg 库制作一个最简单的应用程序。
这是我的代码:

主.c:

#include <libavcodec/avcodec.h>
#include <libavformat/avformat.h>
#include <libswscale/swscale.h>

int main()
{

    avformat_network_init();
    return 0;
}

编译器命令:

gcc -o main main.c -Wall  -lavformat -lavcodec -lswresample -lswscale -lavutil -lm -lz -lpthread -L/usr/local/lib/

导致 :

有没有办法解决这个问题？

好像是 libavformat.so文件版本与其他库不同。
请检查与其他库兼容的版本，如 liavcodec
