Expected behavior

I have recompiled the esp32-arduino-lib using both the cli and pyton gui with both of the following in my defconfig.common targeting an ESP32.

CONFIG_CAMERA_JPEG_MODE_FRAME_SIZE_AUTO=n
CONFIG_CAMERA_JPEG_MODE_FRAME_SIZE_CUSTOM=1048576

My board has 4mb of usable psram but only allocates 300Kb for a 1600x1200 jpeg image which obviously isn't going to work.

Actual behavior (suspected bug)

The build is successful and after having copied the modified library into arduinoIDE there is no effect on PSRAM usage :

log_i("Free PSRAM: %d Total PSRAM: %u", ESP.getFreePsram(), ESP.getPsramSize());
Free PSRAM: 3808108 Total PSRAM: 4194304
Bad jpeg, FFD9 not found

Thinking that the config parameter is being ignored I alter the code in managed_components/espressif__esp32-camera/driver/cam_hal.c as below :

if(cam_obj->jpeg_mode)
{
       cam_obj->fb_size = 3145728;`
} 

After working out that my in source changes would be wiped I write protected the esp32-camera directory and set/exported the IDF_COMPONENT_MANAGER=0 variable so that the change would be pulled into the compilation. I then loaded the library code into arduino and again this had no effect on the jpeg memory allocation.

How can I increase the JPEG_MODE_FRAME_SIZE ?

Error logs or terminal output

Steps to reproduce the behavior

set sdk config variables

CONFIG_CAMERA_JPEG_MODE_FRAME_SIZE_AUTO=n
CONFIG_CAMERA_JPEG_MODE_FRAME_SIZE_CUSTOM=1048576

compile and test any Arduino code that calls the camera_init_function()

PSRAM usage will only increase by 300kb per fb_count.

running copy-to-arduino.sh aka:

rm -rf /home/user/.arduino15/package_esp32_index.template.json && \
cp -f /home/user/Arduino/esp32-arduino-lib-builder/out/package_esp32_index.template.json /home/user/.arduino15/package_esp32_index.template.json

rm -rf /home/user/.arduino15/packages/esp32/tools/esp32-arduino-libs && \
cp -Rf /home/user/Arduino/esp32-arduino-lib-builder/out/tools/esp32-arduino-libs /home/user/.arduino15/packages/esp32/tools

results in arduino not being able to find the newly installed sdk
'/home/user/.arduino15/packages/esp32/tools/esp32-arduino-libs/idf-release_v5.5-129cd0d2-v4/esp32/bin/bootloader_qio_80m.elf' does not exist.

manually renaming the folder structure to one that arduinoIDE is expecting results in missing headers for esp-components in this case espressif__esp32-camera and espressif__esp_jpeg.

copying the necessary headers for the missing includes from the 3.3.1 package (to which I am compiling against) results in ld linker errors to me this means that the esp-components have been skipped ?
...undefined reference to esp_camera_init .... '

Recompiling a fresh pull of esp32-arduino-lib-builder editing only defconfig.esp32 again adding :

CONFIG_CAMERA_JPEG_MODE_FRAME_SIZE_AUTO=n
CONFIG_CAMERA_JPEG_MODE_FRAME_SIZE_CUSTOM=1048576

compiles including required esp-components

#include "PoECAM.hpp"
//#include <SPI.h>

int before;

void setup() {
  // put your setup code here, to run once:
  Serial.begin(115200);
  //SPI.begin(23, 38, 13, -1);
  
  while (!Serial)
    {
    delay(500);
    }

  before = ESP.getFreePsram();
  init_camera();

}

void loop() {
  // put your main code here, to run repeatedly:
  Serial.println(before - ESP.getFreePsram());
  //log_i("Free PSRAM: %d Total PSRAM: %u", ESP.getFreePsram(), ESP.getPsramSize());
  delay(1000);
}

unfortunately still results in a memory allocation of 384016 - aka - FRAMESIZE_UXGA 1600 x 1200 / 5

An inspection of the resulting sdkconfig bundled in esp32-arduino-libs shows that these setting have been ignored

line 2714

CONFIG_CAMERA_JPEG_MODE_FRAME_SIZE_AUTO=y
# CONFIG_CAMERA_JPEG_MODE_FRAME_SIZE_CUSTOM is not set

[me-no-dev]

copy-to-arduino is to be used only for cores inside your sketch folder (manual install from git) and not for cores installed from the board manager. Changes to sdkconfig need to be set into the relevant configs in the configs subfolder of the lib-builder, else they will be discarded.

Thankyou for your time

just to clarify which files should I be editing in my /esp32-arduino-lib-builder folder.
So far I have altered the following files with no effect :

/esp32-arduino-lib-builder/configs/defconfig.common
/esp32-arduino-lib-builder/configs/defconfig.esp32

I had done a search of the whole esp32-arduino-lib-builder and not found where the default value for CONFIG_CAMERA_JPEG_MODE_FRAME_SIZE_AUTO emanates.

The build appears to be ignoring my settings ?

[ArchNemSyS]

I have removed the esp32 from the arduinoIDE board manager

I have followed the instructions at arduino-esp32/en/latest/manual installation

And then copied a fresh compile of esp32-arduino-lib-builder as per copy-to-arduino.sh
/home/user/Arduino/hardware/espressif/esp32/package/package_esp32_index.template.json
/home/user/Arduino/hardware/espressif/esp32/tools

Upon restarting arduinoIDE I get
Platform 'esp32:esp32' not found: platform not installed

I have also tried copying the hardware folder to the one matching under /home/nemsys/.arduino15/packages/esp32/hardware again the platform is not found

Apologies I had not re-selected the board with the version from sketchbook.
The code is now compiling against the manually installed version regrettably.

Unfortunately still results in a memory allocation of 384016 - aka - FRAMESIZE_UXGA 1600 x 1200 / 5

I have followed the guide for editing the defconfig here

unfortunately again the sdkconfig generated inside the out directory has ignored the defconfig
CONFIG_CAMERA_JPEG_MODE_FRAME_SIZE_AUTO=y
#CONFIG_CAMERA_JPEG_MODE_FRAME_SIZE_CUSTOM is not set

again the code does compile but still results in a memory allocation of 384016 - aka - FRAMESIZE_UXGA 1600 x 1200 / 5
