if i use sketch "cameraWebServer" camera is working !!!

E (4868) cam_hal: cam_dma_config(280): frame buffer malloc failed

What kind of board do you have?

You need an ai-thinker esp32-cam board or another with 4 MB of psram.

There is not enough memory psram to allocate the camera buffers for jpeg processing.

You could add this print_ram() line here

cameraWebServer avoids the problem by making a small frame, and slowing down the camera.

Hi sir, thanks for the reply..i am using ai thinker cam ESP32-s after adding that line i got this....

Looks like you got a esp32-cam with 2 MB of psram. That circle-lightning-Y brand.

I've always observed 4MB on my non-AI modules, but I see AI-Thinker says they have 8 MB,

You might be able to modify the code to use less psram ... but it would be some work, and would only operate with a small frame size, and slow recording.
