[Bug]: Crash when using more than one pipewire source #166

Closed Ayowel closed 11 months ago

Ayowel commented 2 years ago

What happened?

Obs craches when attempting to use more that one pipewire source (Screen or window capture). The crash occurs at the moment the new pipewire source is selected in the menu after adding the source to the scene.

Note that this might be a linux-related pipewire issue and not a snap issue.

What should have happened?

The new source should become visible in OBS' preview

    encoder elements.
    * **Move Transition** plugin; move sources to a new position during a scene transition.
    * **NDI** plugin; Network A/V via NewTek's NDI.

  **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/plugins/
     └── 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

I experience the same bug. Seem the same as the one reported here https://github.com/obsproject/obs-studio/issues/7210 . It seems it have been fixed upstream but (maybe) the fix did not come to the snap version.

neutrino82 commented 1 year ago

After a bit more of testing it seems that the same bug is also present in the edge version of the snap package (v 27.2.1). As an effective solution I installed the latest ppa package as reported on the official obs siteand it seems to work fine. At the moment the default version shipped in the ubuntu-universe report fails to start (crashes on startup) in the wayland session so I did not test it.

flexiondotorg commented 11 months ago

Fixed via #172, which updates OBS to 29.1.3 and includes Pipewire audio capture plugin that can handle multiple audio sources and application-specific audio capture.
