#include <libavutil/log.h>
#include <libavformat/avformat.h>

int main(int argc, char* argv[]){
	int ret;
	AVFormatContext * fmt_cxt = NULL;

	av_log_set_level(AV_LOG_INFO);

	av_regitster_all();

        ret = avformat_open_input(&fmt_cxt,".test.mp4",NULL,NULL);

	if(ret < 0){
	   av_log(NULL,AV_LOG_ERROR,"Can't open file: %s \n",av_err2str(ret));
	   return -1;
	}
	av_dump_format(fmt_cxt,0,".test.mp4",0);
	avformat_close_input(&fmt_cxt);
	return 0;
}

执行命令 后报错：

clang -g -o mediainfo mediainfo.c pkg-config -libs libavutil libavformat
报错信息：

Unknown option -libs
mediainfo.c:1:10: fatal error: 'libavutil/log.h' file not found
