Errors while compiling the project

[tb1402]

Hello,
I'm using this project for a while now, but I would like to change the default resolution to 720p/HD, but I can't compile the project.

I'm using esp-idf for the first time and set it up according to your description in issue #1 (installing and setting compiler path via menuconfig).
I now have esp-idf v4.4 with xtensa-esp32-gcc8_4_0-esp-2021r2-patch4 compiler (from here https://github.com/espressif/crosstool-NG ) installed.
I'm using up-to-date amd64 Manjaro-Linux.

When i run make, the following errors are occurring:

It would be nice, if you could help me to resolve this issue or if you could provide a binary with 720p default resolution (or maybe store it on the board, like the wifi credentials).

In espcam2640.c, line 122, replace FRAMESIZE_VGA with FRAMESIZE_P_HD, // 720x1280
This sets the default resolution. (sensor.h)

as for your errors, something seems wrong with configuration. try a demo project if it compiles.
looks like perfmon, the performance monitor.

[tb1402]

I've already changed the framesize when I got the errors above, but I used FRAMESIZE_HD without _P as you suggested, is there any difference?

As for the errors, I got it working today by starting with a fresh install of esp-idf4.4.4. After the example "hello world" compiled successfully, I also used a fresh clone of this repo.
During my previous attempts I switched between esp-idf versions, I think that messed up something in the project folder and caused the errors.

[xenpac]

framesize_t is defined in:
https://github.com/xenpac/ESP32-CAM-Linux-Motion/tree/main/components/esp32-camera-master/driver/include/sensor.h

or just enter the number 11 which should be HD, its probably FRAMESIZE_HD, as the higher ones not used for ov2640.
