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。这是我的代码：

main.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：

有什么办法解决这个问题？

似乎libavformat.so文件版本与其他库不同。请检查与liavcodec等其他库兼容的版本
