如果esp32-cam 不調用car_card_identify()函數時，程序正常運行，一旦調用car_card_identify就會出錯，板子不斷reboot，報錯內容如下，各位大佬，能看出什么錯誤嗎？求指點，已經困擾了2天了//第一次調用

//這應該有問題,strlen是遇到\0即終止計數的。
//在amera_fb_t * 有長度的字段值，看看官方例子
memset(camera_data, '\0', strlen(camera_data));

//base64結果，可能不止原緩沖的長度了
strcat(camera_data, base64::encode(camera->buf, camera->len).c_str() );

好的，我懂了
對了，esp32-cam的看門狗和esp32的看門狗相同嗎？
