OV2640 jpeg image with pixelated edges

[JPMJPM]

Hi,

I have developed a OV2640 camera JPEG streaming solution with :

• Over Ethernet.
• Only two I2S 2.800 32 bits words buffers (ring buffer).
• There is not frame buffer.
• 50 FPS.
• SVGA.

Everything seem to be OK but the image edges are pixelated.
Can anyone tell me what may be happening ?.
I attach TXT (C) and JPEG files.

Thanks in advanced and regards.

Hello, I am trying to make your code work with my esp32 wrover and my ov2640.
but i am getting this error :
E (473) i2c: /components/driver/i2c.c:867 (i2c_set_pin):this i2c pin does not support internal pull-up
E (1483) i2c: /components/driver/i2c.c:542 (i2c_master_clear_bus):scl gpio number error

Can you please tell me which board did you use ? and the connection with your camera ?

I used a ESP32-WROOM module on a custom board.

The connection between ESP32 module and camera is in the source code file.
