[Bug]: Needed to manually connect wayland #169

Closed RJDan closed 8 months ago

RJDan commented 11 months ago

What happened?

The snap did not start. It gave error 

Failed to create wl_display (Permission denied)
qt.qpa.plugin: Could not load the Qt platform plugin "wayland" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, xcb.

Aborted (core dumped)

After running 

 snap connect obs-studio:wayland

obs-studio interface came up as expected.

What should have happened?

The snap should have started when I initially launched the snap.

Please include the wayland connection in the snap info (if it was supposed to be there).

  **Connecting Interfaces**

  For the best experience, you'll want to connect the following
  interfaces.

     sudo snap connect obs-studio:alsa
     sudo snap connect obs-studio:audio-record
     sudo snap connect obs-studio:avahi-control
     sudo snap connect obs-studio:camera
     sudo snap connect obs-studio:jack1
     sudo snap connect obs-studio:kernel-module-observe

  **NDI**

  If you want to use the NDI plugin you'll need to connect the
  Avahi Control interface.

     snap connect obs-studio:avahi-control

  **Virtual Camera**

  Starting with OBS 26.1.0, Virtual Camera support is integrated.
  Here's how to install and configure `v4l2loopback`:

     sudo snap connect obs-studio:kernel-module-observe
     sudo apt -y install v4l2loopback-dkms v4l2loopback-utils
     echo "options v4l2loopback devices=1 video_nr=13
     card_label='OBS Virtual Camera'    exclusive_caps=1" | sudo
     tee /etc/modprobe.d/v4l2loopback.conf
     echo "v4l2loopback" | sudo tee
     /etc/modules-load.d/v4l2loopback.conf
     sudo modprobe -r v4l2loopback
     sudo modprobe v4l2loopback devices=1 video_nr=13
     card_label='OBS Virtual Camera' exclusive_caps=1

  **NOTE!** Using `video_nr` greater than 64 will not work.

  **Removable Storage**

  To access content on external storage, connect to the
  removable-media plug:

     snap connect obs-studio:removable-media

  **gPhoto**

  The gPhoto plugin allows some DSLR cameras to be connected via
  USB. You'll need to connect the Raw USB interface.

     snap connect obs-studio:raw-usb

  **3rd Party plugins**

  To install pre-compiled plugins, download and extract the plugin
  to
  `~/snap/obs-studio/current/.config/obs-studio/plugins/`.

  This is how the Input Overlay plugin looks when correctly
  installed:

     /home/username/snap/obs-studio/current/.config/obs-studio/plug
     ins/
     └── input-overlay
         ├── bin
         │   └── 64bit
         │       └── input-overlay.so
         └── data
             └── locale
                 ├── de-DE.ini
                 ├── en-US.ini
                 └── ru-RU.ini

  If you want to use the Input Overlay plugin, you'll also need to
  connect the joystick interface:
     snap connect obs-studio:joystick
commands:
  - obs-studio.eglinfo
  - obs-studio.ffmpeg
  - obs-studio.ffplay
  - obs-studio.ffprobe
  - obs-studio.glxinfo
  - obs-studio
  - obs-studio.srt-ffplay
  - obs-studio.srt-file-transmit
  - obs-studio.srt-live-transmit
  - obs-studio.srt-tunnel
  - obs-studio.vainfo
  - obs-studio.vdpauinfo
