Good night friends!
I have a project from my graduation where I will use the esp32cam stream and with a button to activate the servo controlled gate.
Below I have my code. The Button works correctly, where I press it and the gate opens and then closes.
However, my problem is that the stream needs to be open and I have this output error:
ho 0 tail 12 room 4
load:0x40078000,len:10944
load:0x40080400,len:6388

Camera Stream Ready! Go to: http://192.168.1.152

Yes, even before the implementation of the servo and button the stream was recording normally!
And I'll switch library to ESP32Servo and validate if something changes!
TKS Idahowalker!
When the servo is attached, just attach it once in setup.
How is the servo being powered? I found the ESP32CAM to be very fickle about its 5V's.
The servo motor is being powered with 5v from an external source.
I change the library, and now ins't work my servo!
And the problem exist
Sorry I was unable to help.
