Hi, I try to make security system - "door opens, photo takes". But when i take photo - there is not realtime photo - seem like some old frame from internal buffer. I'm not understand how take realtime photo. Here code example which shoul give realtime photo:

Code: [Select all] [Expand/Collapse]

  server.on("/picture", HTTP_GET, [](AsyncWebServerRequest * request) {
 
    camera_fb_t * frame = NULL;
    frame = esp_camera_fb_get();
 
    request->send_P(200, "image/jpeg", (const uint8_t *)frame->buf, frame->len);
 
    esp_camera_fb_return(frame);
  });

Did you ever figure this out? I'm running into the same behavior.

I also face the same problem, but with Examples->ESP32->Camera->CameraWebServer
I suspect it has to do that I use Arduino IDE instead of PlatformIO, but hard to tell without switching.

Add to your code: config.grab_mode = CAMERA_GRAB_LATEST;
