[SOLVED] RPi Cam Web Interface Not Starting

Tue Sep 13, 2022 6:49 pm

I have connected an RPi IR-CUT Camera - similar to https://www.waveshare.com/wiki/RPi_IR-CUT_Camera - to a Raspberry Zero v.1 with Raspian (5.15.61+ #1579 - terminal only). I have installed RPi-Cam-Web-Interfce as per their wiki https://elinux.org/RPi-Cam-Web-Interface. However, the interface won't start. Upon running the start.sh script in the RPi_Cam_web_interface-folder I keep getting:

Code: Select all

    user@Camera01:~/RPi_Cam_Web_Interface $ ./start.sh
    mmal: mmal_vc_component_create: failed to create component vc.ril.camera' (1:ENOMEM)
    mmal: mmal_component_create_core: could not create component vc.ril.camera' (1)
    sh: 1: /var/www/html/macros/error_hard.sh: Permission denied
Running the debug.sh-script gives me:

Code: Select all

    user@Camera01:~/RPi_Cam_Web_Interface $ ./debug.sh 
    start monitoring for pid: 18262
    {2022/09/09 09:38:11} start monitoring for pid: 18262

    mmal: mmal_vc_component_create: failed to create component vc.ril.camera' (1:ENOMEM)
    mmal: mmal_component_create_core: could not create component vc.ril.camera' (1)
    Error: Could not create camera
    Executing macro /var/www/html/macros/error_hard.sh "Could not create camera"  
    sh: 1: /var/www/html/macros/error_hard.sh: Permission denied
The camera's web page only shows the Apache server (with no subfolders or anything else):

Index of /
[ICO] Name Last modified Size Description
Apache/2.4.54 (Raspbian) Server at 10.0.0.200 Port 80`

I have tested the camera with libcamera-jpeg, and it outputs an image to a jpeg without problems:

As suggested [here](https://stackoverflow.com/questions/410 ... ce-running), permission errors may be caused by processes with root privileges hogging the camera. However, no candidates stand out:

Have you enabled legacy camera support as they say: "Legacy camera support should be enabled. Do this within raspi-config under Interfce. If this shows just "Enable camera" then update raspi-config itself from its menu item."

As a test I installed the current Bullseye LITE (32-bit) onto a pizero W with a camera and installed the excellent RPi-Cam-Web-Interface
It failed to start unitl I enabled the Legacy camera Interface using raspi-config, as per the instructions.
It then worked perfectly.

Thanks. That got the camera going. Or so it seems. No error messages. However, the webpage is still showing just Apache:

My bad. Didn't look in the right subfolder. It works. Thanks!

I think it sets “html” as the sub-folder by default.
