(Solved) Mopidy Mobile crashes

General

Hi,

I encounter a websocket error as soon as I select any track via the Mopidy-Mobile frontend. It seems that mopidy crashes, because sudo systemctl status mopidy gives me:

● mopidy.service - Mopidy music server
   Loaded: loaded (/lib/systemd/system/mopidy.service; enabled; vendor preset: enabled)

But I have no idea what exactly fails. I once saw the error “failed to open vchiq instance” and in the log I found unicode warnings but nothing 100% reproducable. Does someone know where I can look for the error?

I use Mopidy as a service on a Raspberry 3 B with Raspbian Stretch.

Thanks in advance!

The vchiq error is a raspberry pi specific problem in our Debian package. The fix is to add the mopidy user to the video group. See * failed to open vchiq instance

Hi kingosticks,

sorry for the late reply. I added mopidy to the video group (sudo adduser mopidy video) as it was done in the other topic and it worked!
Thank you very much for your help!

By the way, are you using the Raspbian Desktop image or the Lite image?

I am using the desktop image.

I’ve just set up Pi0 with Stretch Lite and it appears you don’t need Mopidy to belong to the Video group in the Lite version - things are playing fine using musicbox webclient and a usb audio card.
I meant to try it before, you jogged my memory with this post.

pi@raspberrypi:~ $ groups mopidy
mopidy : audio

Thanks. That’s what I found too. I’m updating the docs to reflect the fact (https://github.com/mopidy/mopidy/pull/1669).
