如果esp32-cam 不调用car_card_identify()函数时，程序正常运行，一旦调用car_card_identify就会出错，板子不断reboot，报错内容如下，各位大佬，能看出什么错误吗？求指点，已经困扰了2天了//第一次调用

//这应该有问题,strlen是遇到\0即终止计数的。
//在amera_fb_t * 有长度的字段值，看看官方例子
memset(camera_data, '\0', strlen(camera_data));

//base64结果，可能不止原缓冲的长度了
strcat(camera_data, base64::encode(camera->buf, camera->len).c_str() );

好的，我懂了
对了，esp32-cam的看门狗和esp32的看门狗相同吗？
