Something forgotten in CameraWebServer /app_httpd.cpp?

[Joey-1970]

Hello!

If you take a status-update from the webserver with IP/status, I get something like this:
{"0xd3":8,"0x111":0,"0x132":137,"xclk":20,"pixformat":4,"framesize":2,"quality":10,"brightness":0,"contrast":0,"saturation":0,"sharpness":0,"special_effect":0,"wb_mode":0,"awb":1,"awb_gain":1,"aec":1,"aec2":0,"ae_level":0,"aec_value":168,"agc":1,"agc_gain":0,"gainceiling":0,"bpc":0,"wpc":1,"raw_gma":1,"lenc":1,"hmirror":0,"dcw":1,"colorbar":0,"led_intensity":210}
I miss something like "vflip"?

I'm not really sure but I think there is something forgotten in
https://github.com/espressif/arduino-esp32/blob/master/libraries/ESP32/examples/Camera/CameraWebServer/app_httpd.cpp
near line 479, something like:
p += sprintf(p, "\"vflip\":%u,", s->status.vflip);

I wonder, too, why there ist no message in status-update for "Face Detection", "Face Recognition" or somethink like this?

P.S.: Is there somewhere a documentation for HTTP commands?
