测试指令 利用mpeg4编码方式

使用指令 ffmpeg -f image2 -i %02d.jpg -vcodec mpeg4 -s 1920x1080 multi_jpg3.mp4

配置开发文件

打开属性面板

解决方案资源管理器->右键单击项目->属性

头文件配置

配置属性->C/C++->常规->附加包含目录，输入“ include”（刚才拷贝头文件的目录）

导入库配置

配置属性->链接器->常规->附加库目录，输入“ lib” （刚才拷贝库文件的目录）

动态库不用配置

测试

// FFmpeg.cpp : 定义控制台应用程序的入口点。
//#include "stdafx.h"
#define __STDC_CONSTANT_MACROSextern "C"

}

打断点，如果不打断点，调试的时候一闪而过什么也看不到的。

}

这是我写的工程文件：FFmpeg 工程文件

        char bufName[50];int i = 0;for (i=1;i<=1000;i++)//while (frame_index<100)//将图像压入视频中{sprintf(bufName, "%04d.jpg", i);printf("%s\n",bufName);FILE *file;//打开一张jpeg图像并读取其数据，在这里图像最大为1M,如果超过1M，则需要修改1024*1024这里fopen_s(&file, bufName, "rb");pkt.size = fread(mydata, 1, DATASIZE, file);pkt.data = mydata;fclose(file);if (av_interleaved_write_frame(ofmt_ctx, &pkt) < 0) //写入图像到视频{printf("Error muxing packet\n");break;}//printf("Write %8d frames to output file\n", frame_index);//打印出当前压入的帧数//frame_index++;}

根据实际情况修改 DATASIZE ，应超过图片大小的最大值。

#define DATASIZE 1024*1024*50

然后，还要根据实际情况修改图片的参数信息。

    st->codec->bit_rate = 400000;//设置采样参数，即比特率  st->codec->width = 5184;//设置视频宽高，这里跟图片的宽高保存一致即可st->codec->height = 3456;st->codec->time_base.den = 2;//设置帧率st->codec->time_base.num = 1;
