It’s worth noting that this is a hardware limit of the esp32-cam. It’s not possible to do a 90degree rotate since the ov2640 camera itself does not provide that (it does provide v-flip and h-mirror) and the ESP32 doesn’t have enough cpu/fast ram to rotate the images in real time.
This is a PITA if you want to monitor a doorway or stairs, where portrait mode is convenient.
On my (non HA) project I do it via a browser rotate and some js/css, nice to see that HA has provision for this too, I was wondering if it would prove a sticking-point in my evolving setup.
