VS2012上实现YUV文件的拼接

// 本程序可将yuv 的两个视频合为一个文件，从而建立带有场景切换的视频序列 #include <stdio.h> #include <Windows.h> #include <stdlib.h> #include <memory.h> #include <string> #define FOPEN(fHandle,filename,mode) fopen_s(&fHandle, filename, mode) #define BFSIZE 1024 int main(int argc,char *argv[]) { //创建新文件，用以存储合并后的视频序列 FILE *newfd, *oldfd1, *oldfd2; FOPEN(newfd, "E:/MyVideo/amfy.yuv", "ab+"); if(newfd == NULL) { printf("open newfd failed ! \n"); return -1; } //打开需要合并的文件进行读取 FOPEN(oldfd1, "E:/MyVideo/amfy_0.yuv", "rb"); if(oldfd1 == NULL) { printf("open oldfd1 failed ! \n"); return -1; } FOPEN(oldfd2, "E:/MyVideo/amfy_1.yuv", "rb"); if(oldfd2 == NULL) { printf("open oldfd2 failed ! \n"); return -1; } //**************************************************************** //char buffer[BFSIZE]; //memset(buffer, 0, sizeof(BFSIZE)); //读取文件1，将文件1的数据存储到新文件中 int ret = 0; int re_value = 0; while(1) { char buffer1[BFSIZE] = {0}; ret = fread(buffer1, 1, BFSIZE, oldfd1); if(ret == 0) break; else { fwrite(buffer1, 1, ret, newfd); } } re_value = fclose(oldfd1); if(re_value) { printf("close file1. \n"); return -1; } //读取文件2，将文件2的数据存储到新文件中 while(1) { char buffer2[BFSIZE] = {0}; ret = fread(buffer2, 1, BFSIZE, oldfd2); if(ret == 0) break; else { fwrite(buffer2, 1, ret, newfd); } } re_value = fclose(oldfd2); if(re_value) { printf("close file2. \n"); return -1; } //**************************************************************** re_value = fclose(newfd); if(re_value) { printf("close newfile. \n"); return -1; } return 0; }
