Which ESP32-CAM PlatformIO demos work in 2024?

The only demo which worked out of the box in June 2024 for my chinese ESP32 demo was


The other demos I tried (which did not work) were:

I can’t rule out that I used them wrong, but both of these exhibited compile errors, leading me to believe. I tried debugging them but in the end, I only got pio-esp32cam to work.

While I could compile esp32cam-ready after a few simple modifications relating to old Arduino API versions, I couldnt make it connect to my Wifi as it didn’t start the SoftAP for provisioning.
