But, if I run /usr/bin/vlc -f /home/pi/pikaraoke-songs/filename.mp4 The video plays.

(Yes, my username is pi eventhough it's installed on an x86 machine :)) I also created a symlink of /root/pikaraoke-songs to /home/pi/pikaraoke-songs and made the directories accessible.

I've encountered what I believe to be similar errors running on a RPi4 (specifically the "vlcpulse audio output error" and the dbus interface error following it in your log). I've not yet found a cause or workaround but I noticed that if I launch the pikaraoke app from power-up (using \etc\rc.local) it usually works, but if I quit back to the pi desktop and re-run from the CLI in a shell window, with exactly the same command that worked from rc.local, the app runs and videos play but there's no sound. At that point, if I run VLC directly the videos play with audio working fine. It's as if there's an explicit audio option or parameter missing from the vlc command within the app, similar in purpose to the -a option provided for omxplayer. It defaults correctly from rc.local launch of the pikaraoke app, and from direct VLC launch from desktop, but defaults to some other audio when pikaraoke gets re-launched after quitting. Apologies if this turns out to be a different issue, but there seem to be enough parallels to make it relevant.

In my case, if I run "/usr/bin/vlc -f /home/pi/pikaraoke-songs/filename.mp4" the video plays without any problem but after the video is done playing I see something like this:

VLC media player 3.0.12 Vetinari (revision 3.0.12-1-0-gd147bb5e7e) [00005594927d6f10] main interface error: no suitable interface module [00005594926f2570] main libvlc error: interface "globalhotkeys,none" initialization failed [00005594926f2570] main libvlc: Running vlc with the default interface.

Then I have to type ctrl+C to terminate vlc.

Gong back to PiKaraoke, if I run "sudo python3 app.py", the web interface is working as it should. Search and download is working, also queueing. But after queue, the song shows up in the Home tab but only for a few seconds as if it played and finished the song.

I also tried to launch the app from power-up (using systemctl .service) but, alas! I still get the same result. :(

Just to be clear, you're running on linux? Have you tried without running python3 app.py without sudo?

[troy-lim]

Just to be clear, you're running on linux?

Yes. Debian Buster on an Intel atom.

[vicwomg]

this is probably because you ran once as sudo and it generated the qrcode with root permissions. If you sudo rm /home/pi/pikaraoke/qrcode.png then try again you should get further

It says unable to open mouse.

[vicwomg]

Ok, back to sudo then, pygame is being restrictive... especially when running in a non-desktop environment, which sounds familiar. Did you try patching vlc so that it can run as sudo? As it turns out, this is a necessary step in the pi installations:

sed -i 's/geteuid/getppid/' /usr/bin/vlc

Yes I did. I can launch vlc as root.

Then I am at a loss, hopefully someone with more direct Linux experience can chime in

Thank you so much for the effort. Hope that someone out there can give some light into this. I'm running out of space in my RasPi-Pikaraoke. :)

Okay, here's what I've noticed.

I've noticed that there is always an XDG_RUNTIME_DIR error. I tried adding the username to the 'video' group and adding Defaults env_keep += "https_proxy" to sudoers and still no luck.

So, I think we might want to be using cvlc instead of vlc, which avoids it trying to start the interface.

Also if you get the Ascii art display, you need to pass DISPLAY=:0 to force it to not try and draw in the current terminal.

I tried using clvc but the result is still the same.

Do you have any idea on how to do this? I tried different methods but I can't seem to get it right.

I'm using systemd to run on boot

https://github.com/tbelaire/pikaraoke/blob/service/pikaraoke.service#L16

And I added it to the ENV.

But I think you could do something with os.environ["DISPLAY"] = ":0" from inside the process.

If running directly, it would be

DISPLAY=:0 python app.py

Have you tried without running python3 app.py without sudo?

Hi, I had a similar issue running without sudo, but running with sudo wouldn't load sound. I found that if you just made the user the owner of the qrcode file and run without sudo, it works. I am on ubuntu, and I did chmod sudo chown user qrcode.png then launched without sudo and it worked. Maybe give it a try?
