ffmpeg通过API重命名文件

通过修改name1.txt文件为name2.log 来学习avpriv_io_move("name1.txt","name2.log");

代码部分

#include <libavformat/avformat.h>
#include <libavutil/log.h>
int main(int agrc,char* argv[]){
    av_log_set_level(AV_LOG_DEBUG);
    int ret = avpriv_io_move("name1.txt","name2.log");
    if(ret<0){
        av_log(NULL,AV_LOG_ERROR,"Failed to rename file name1.txt \n");
        return -1;
    }
    av_log(NULL,AV_LOG_INFO,"Success to rename file name1.txt ---> name2.log\n");
    return 0;
}

编译

gcc -g -o rename rename.c `pkg-config --cflags --libs libavutil libavformat`

运行

./rename
