Exception when requesting snapshot

[fgolemo]

Heyhey thanks so much for putting this firmware together!

I installed this on my Freenove Esp32-Wrover-Dev board and the wifi hotspot and config interface worked. But as soon as I try to click on the /snapshot link, the board throws an exception and reboots:

Any idea what this could be? I've tried multiple settings including turning off PSRAM, setting the resolution to 640x480 and buffer to 1 but this still happens.

EDIT: the same thing happens when I try to open the RTSP stream in VLC.

Hi Florian,

I think something goes wrong when the camera is initialized/used. Have to configured the right board? To dig deeper into the logs, could you add the exception decoder to find out where exactly it fails?

monitor_filters = esp32_exception_decoder

This will decode the crash stack
