Crash using defined CAMERA_WIDTH and CAMERA_HEIGHT

[ziolelle]

Hi, using the predefines values in config.h I experimented crash in camera initialization:

I changed config.h with these values:

define CAMERA_FRAME_RATE 30
//#define CAMERA_FRAME_SIZE FRAMESIZE_VGA
#define CAMERA_FRAME_SIZE FRAMESIZE_QVGA

//#define CAMERA_WIDTH 640
//#define CAMERA_HEIGHT 480
#define CAMERA_WIDTH 320
#define CAMERA_HEIGHT 240

// #define VIDEO_WIDTH 160
// #define VIDEO_HEIGHT 120
#define VIDEO_WIDTH 80
#define VIDEO_HEIGHT 60

and changed also file accessory.c at line 755 and 756 disabling the comment on:

    tlv_add_integer_value(video_attributes, 1, 2, CAMERA_WIDTH);  // Image width
    tlv_add_integer_value(video_attributes, 2, 2, CAMERA_HEIGHT);  // Image height
//    tlv_add_integer_value(video_attributes, 1, 2, 640);  // Image width
//    tlv_add_integer_value(video_attributes, 2, 2, 480);  // Image height
    tlv_add_integer_value(video_attributes, 3, 1, CAMERA_FRAME_RATE);  // Frame rate

now the camera is working. Is it ok or I missed something ?

[ziolelle]

Sorry forgot to tell you that looking at the code, the error was generated trying to allocate memory for the framebuffers (original values were trying to allocate 76K).

[maximkulkin]

Not sure why 640x480 does not work for you, it worked on 4 different models I tested on. What kind of module did you use? Did you follow configuration procedure described in README?

[ziolelle]

Yes, I followed the README step by step. The model is one found on Aliexpress: ESP32-CAM WiFi Wireless module ESP32 Serial to WiFi ESP32 CAM SPI Flash Bluetooth Development Board with OV2640 Camera Module

Initially the model worked as a charm but a lot of time ago

[maximkulkin]

Oh, I just noticed this: to change resolution before it wasn't enough to just change it in that header file, you had to adjust other parameters in the code. I updated config.h, so that everything is in one place. Although, the crash because of that shouldn't have happened that early. Anyways, update the code and give it a try. And if that does not work, revert all your changes, you're not yet qualified to make them.

[ziolelle]

Thanks I will test it

[ziolelle]

Really thanks, it work with no further mods. Now however as I already wrote in the followup for issue #44 I am getting the same "coloured snow" in streaming mode.

Consider this issue closed

really thanks
