Would it be possible to get a configuration screen like the basic esp32cam examples? This would make it easier to change the settings on the fly and be able to trade off between multi client responsiveness and image quality etc.

I am new to the ESP-32 Cam so please bear with me.
I am trying to upload the Multiclient code to my ESP-32 Cam and consistently error saying

'server' was not declared in this scope
Not used: C:\Program Files (x86)/Arduino\libraries\WiFi
exit status 1
'server' was not declared in this scope

Thanks

The multiclient webserver is working very well with my AIThinker compatible ESP32-CAM. Thus, it would be great if you implement a button to toggle on board LED via webserver.

There is, I think, a race hazard if you have clients using the MPJEG stream and static picture URL at the same time in that that that it is possible for both threads to be accessing the camera object at the same time. This can then result in bad things happening with regard to the memory buffer pointer returned from the camera class. I can very quickly crash the board under these conditions.

I think you need a semaphore around the camera object accesses - the attached patch seems to work for me.

Cheers,

Jon.

Hi,
80% of the time, I am connecting only from a single client, still, the camera is only loading partial image and at a relatively slow rate ~7fps.
I did notice that the performance reduction is related to jpg/mjpg compression. For example: I see a complete image when the picture is "static", and partial picture when the picture is changing (wind blowing leafs).
I am using 4 esp32 cameras as a motion detection / surveillance system and for now, my workaround to the above problem is to set inspection windows away from the bottom of the frame (where the image is not loading properly), but I am wondering what do you recommend for improving performance (lower frame rate ? smaller frame size ? Thanks

Hi, there's an issue capturing jpg image while another client is streaming mjpg, most of the time the jpg image is garbled:

and it often stops mjpg streaming on the other client altogether with an error in the log (have to reset the esp32 to make it work again)
[E][camera.c:1483] esp_camera_fb_get(): Failed to get the frame on time!

Hi there
Testing on mac and windows desktop browsers and safari on Iphone
when entering http://192.168.0.170/mjpeg1/1
On desktop I get the following response :
Server is running!

URI: /mjpeg1/1
Method: GET
Arguments: 0

On Iphone I am asked if I want to download 1

Working no problem on Android mobile browser and vlc

Kind Regards

Hi all,

thx for this project!

I also found a nice project in order to be able to use the LED flash light.
https://github.com/xenpac/ESP32-CAM-with-LED-control

Is it possible to combine both projects?

Could somebody point me to the right tutorial in order to have both projects working on the ESP32 cam?
I am new to ESP32 and Arduino IDE.

thx for your support!

Hi @arkhipenko , firstly, thanks for your project. It was a really good and useful project for me. And I want to stream with LAN network, Can you help me, pls???, I set 2 modes (WLAN and AP mode) but LAN mode I can't set.

hi i want use esp eye as realtime face recognization can i use this ?

if yes how to train bulk images in this ? is it possible to train the model in esp eye or we need train the model in server ?

we need some help if u give it is very helpful for me

Likedocument.body.style.transform = "rotate(90deg)";
How to change the code?
Thanks

Hi! - found your project when looking for ways to stream to multiple clients using a standard web browser.
Im currently basing much of my work off the CameraWebServer example. Any pointers/guidance on where I could make use of your ideas would be great.

Thanks

I am getting this in the serial output and the camera restarts.

Camera is NOT faulty, just tested a cam web server and that code works

Hi I'm using an AI-Thinker board and was able to flash your code.

I activated

But somehow I get a Brownout detector was triggered reboot-loop at OV2640.cpp l184:

It seems that the cam can't be initialized with the given config for AI-Thinker.
(I also tried the other configs and they also don't work)

Here the board for reference:

Hi there, Is it possible to stop all the tasks of streaming and also its server so that I can reuse the port 80 again for ota update?

I was getting the error

what do I need to do?
