HAL层Camera模块Dump图片--工作积累

导出YUN数据进行调试，分析问题：

 1 // dump图像数据  事列
 2 void   dump(const int width, const int height, void *yBuf, void *uvBuf)
 3 {
 4        char buf[256] = {‘\0‘};
 5        FILE* file_fd = fopen(buf, "wb");
 6        snprintf(buf, sizeof(buf), "/data/Effect/%dx%dvideodenoiser%d.yuv",width,height,4);
 7        file_fd = fopen(buf, "wb");
 8          if (file_fd != NULL) {
 9         void *data = NULL;
10         int written_len = 0;
11         data = (void *)((uint8_t *)yBuf);
12          written_len += fwrite( data, width*height, 1, file_fd);
13         if(NULL == uvBuf)
14             data = (void *)((uint8_t *)yBuf+ width*height);
15         else
16             data = (void *)((uint8_t *)uvBuf);
17         written_len += fwrite( data, width*height/2, 1, file_fd);
18         fclose(file_fd);
19         TSLOG("%s: dump-------sucess%d",__func__,4);
20         } else {
21         TSLOG("%s: fail t open file for image dumping", __func__);
