No Image showing

[vmiyoshi]

I physically installed the camera module Run the Prerequisite Then I decided on the "Installation (as homebridge plugin)," and not the "Installation (standalone)" because this device already has a working homebridge install with the Nest plugin loaded. After everything was said and done, I have a "Pi Camera" in homekit, but no image. I see a Video camera icon with a "/" through it.

[moritzmhmk]

Can you post the error log of homebridge?

Depending on how you installed it you might get it with journalctl -u homebridge.

[Fasani]

I get the same issue, I think.

I think this part did not work. module bcm2835-v4l2 loaded (add bcm2835-v4l2 to /etc/modules and reboot)

Log says it couldn’t write to the folder Videos/0

Or something like that, which I read is connected somehow to the module part of the install.

Any hints for module issues?

[Fasani]

I got it working, basically I did this:

sudo nano /etc/modules // at the end of the file, add this line: bcm2835-v4l2

[Fasani]

I get a video update about every 10 seconds, is streaming possible in the main home view mini panel?

It’s streaming live when you click the camera. I guess it doesn’t stream in the main home view mini mode?

[moritzmhmk]

It is supposed to only update still images in the main view.

[Fasani]

When the light is off and the camera is effectively sending black data, I get a live feed no problem, when light comes on I wait for around 60 seconds and then it says stream is offline. I guess the Pi is struggling with encoding?

[Fasani]

Answering my own question: Works fine after IOS restarted. Also tested on macOS Mojave in the new HomeKit app, works there also.

[Fasani]

Any tips on adding a second pi camera attached to a second raspberry pi on the network and appearing in HomeKit?

[tokamac]

I have the same issue since a few days: black screen, no still picture in Home. When clicking on it, the LED lights up on the pi camera, but there is no video stream (seconds counts on the upper left part in Home, displaying the line "Loading…" and a crossed camera icon eventually shows up in the middle of the screen).

[mhermosi]

I just installed the plug in.. I have tested the streaming using motion, now that I have installed the plugin, disabled motion (module is loaded device present) I see this on log:

i got this

[mhermosi]

hey @Nijisakai can you see /dev/video0 ? ls -l /dev/video0 ?

if you can, verify if you are running as root or pi, BTW which raspberry pi are you using?

[moritzmhmk]

is this solved?

[Macoperator]

Unfortunately not solved. I've got the same error. Running on a Raspberry Pi Zero W. /dev/video0 is owned by root homebridge error message states: "v4l2-ctl Failed to open /dev/video0: Permission denied"

Workaround for me was to install and use the standalone version.

[moritzmhmk]

Is homebridge run as a user other than pi? If so add that user to the group video.

[sweetw0r]

added root to video group and still getting:

[sweetw0r]

sudo chmod 777 /dev/video0 helped!

[firelizzard18]

@sweetw0r Usually that file is owned by root:video. Given that changing the mode of a device file is not really permanent (next reboot should forget that change), I suggest you instead add the user (homebridge probably) to the video group: sudo usermod -aG video homebridge.

This is what @moritzmhmk is suggesting.
