webcam.py not working

[aleggon]

camera.init() requires at least one positional argument, which you do not provide when testing at first. But that does not solve the problem: the ESP32-CAM board reboots and throws errors:

camera.init(0, format=camera.JPEG)

I've just updated the application. Last week, I updated the driver, and forgot to update the uPyCam (master branch). The timelapse branch was working. Please download and flash the firmware again. I added a streaming mode too.

any news?

Hi, it works with the old webcam.py, but it fails or reboots the board most of the time I try to init() the camera. It does not work with the new webcam.py.

[lemariva]

Did you flash the new firmware? I've just tested both modules (esp32-cam and m5camera) again and they worked with the new camera application (last commit). You need to change in the config file the setting for your camera ('camera': 'ESP32-CAM'). If you try to initiate the camera twice, the ESP32 reboots. But as I mentioned, the firmware and application are working.

You are right. It works. I had not set the config file (it was not clear in your article how to do that). But the the board reboots too often with the new firmware. It is not as reliable now as it use to be.

I get this all the time:

I think you're having a hardware problem.

• Try to erase the flash using esptool.py --chip esp32 --port /dev/ttyUSB0 erase_flash, flash the firmware, and upload the code again.

I used the camera without any problem and made an 8-hour test today. And as I see, you are having problems after about 28 seconds.

• Check the camera connector, and mount the camera again, maybe it's a loose connection

Keep me updated!
