Hey all:
I thought I'd start learning about ESP32-CAM for an upcoming project. So, I got an AI-Thinker (with PSRAM) and an external antenna.
The CameraWEbServer example compiled and downloaded without issue and worked right out of the box. Well, ALMOST. Streaming video to the browser client worked great. I think it's quite impressive. I poked around a little in the code and saw that esp_camera.h provides some very sophisticated APIs and it will take me quite awhile to learn them ... I got time.
I said it ALMOST worked right out of the box. What didn't work was Facial Detection / Recognition. Nothing happened after enabling those on the Web page. I didn't get the little rectangles around faces as shown in countless YouTube videos.
Looking in app_httpd.cpp, I see a lot of conditionally-compiled code that depends on the macro 'CONFIG_ESP_FACE_DETECT_ENABLED' begin defined. So, I naively defined it and tried to compile again. Now there were complaints that the file "fd_forward.h" couldn't be found.
I have ESP32 cores v2.0.1 and v2.0.2 installed and the file "fd_forward.h" does not exist anywhere in those.
So, finally, the question .... does anyone know of a combination of ESP32 core version and board type selection (and perhaps Aduino IDE version) that has Facial Detection / Recognition working with the built-in CameraWEbServer example?
Thanks.
EDIT
PS - FYI, question also posted here.
