1 year ago The problem is that you are trying to init the camera every request. It should be inited once in setup.

Description
Actually I'm searching for a simple code to test my camera which can be ported to ESP-IDF later (Arduino as component) came across a code but whenever i try to access it through my ip address i get below error constantly
i tried traditional esp32 cam web server code its working fine but iam unable to port it to ESP-IDF since it showing some files are missing related to
app_httpd.cppSketch
Debug Message
Other Steps to Reproduce
No response
I have checked existing issues, online documentation and the Troubleshooting Guide
