hey guys
All good
I bought an esp32 with a camera to do some tests here.
Using the Arduino IDE I can compile it correctly and it works well.
I can't compile in B4R It's giving an error
Can anyone tell me what is going on I would appreciate it

B4R: 
\Cesar\\AppData\\Local\\Arduino15\\packages\\esp32\\hardware\\esp32\\2.0.11\\libraries\\WiFi\\src" "-IC:\\Users\\Cesar\\AppData\\Local\\Arduino15\\packages\\esp32\\hardware\\esp32\\2.0.11\\libraries\\WiFiClientSecure\\src" "C:\\Users\\Cesar\\Desktop\\ESP32_~1\\ESP32C~1\\Objects\\bin\\sketch\\b4r_esp32cam.cpp" -o nul

Hello everyone
About errors when compiling
I have no idea what these files are?
If you remove 02 two it compiles normally but the camera does not appear on the IP and this message "use /live to get the live stream or /pic for a picture capture "
thanks for the h

B4R: 
#include "img_converters.h"
//#include "Arduino.h"
#include "fb_gfx.h"
//#include "fd_forward.h"
//#include "fr_forward.h"
#include "FS.h"                // SD Card ESP32
#include "SD_MMC.h"            // SD Card ESP32
#include "soc/soc.h"           // Disable brownour problems
#include "soc/rtc_cntl_reg.h"  // Disable brownour problems
#include "driver/rtc_io.h"
#include <EEPROM.h>            // read and write from flash memory

Hi Cesar:

ESP32 Camera Picture Capture and Video Streaming! (Updated with code!)

Hello! Last December I made a request for support for the ESP32 Camera support. Well, I finally found the time to work on it myself and here's my initial attempt at implementing this with B4R. I'm using an ESP32CAM camera board with 4GB of PSRAM (like extended memory for the camera). I'm...

Hello everything is fine
Yes
I've done the readings a few times.
I can't get a compilation to always give these 2 errors. Thank you from the bottom of my heart, I'll read it ++++

About the two error files
It doesn't matter much
It works without them
B4R: 
#include "fd_forward.h"
#include "fr_forward.h"

About the color problem in my case it was black and white
B4X: 
 //s->set_pixformat(s,PIXFORMAT_GRAYSCALE); //FIXME - couldn't get grayscale mode to work, missing some other config option
  s->set_special_effect(s, 0); //gray scale  It was 1 mode to 0
Thanks

FYI,
I was curious what these files were for and did a little research on the internet.

#include "fd_forward.h" is for Face Detection
#include "fr_forward.h" is for Face Recognition

Apparently, you are supposed to be able to save a Face and the Camera can recognize that specific Face.
Also, from what I read it did not work.

Hello KiloBravo
All good
So that's what it's for, I didn't know
I'll be happy if he can take some photos and save it on the card
Thank you for your response

I played with the esp32 camera modules back in 2022 as well. I did not use B4R or an SD card. But you may find my comments helpful.
