Package: obs-studio
Version: 26.1.2+dfsg1-2
Severity: normal

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?
     I wanted to use obs-studio with Zoom or Microsoft Teams. I am also
     a user of the package nvidia-driver.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
     I installed v4l2loopback-dkms before starting obs-studio,
     configured my scene in obs-studio and hit the button "start virtual
     camera". 

   * What was the outcome of this action?
     The virtual video device appeared in Zoom or Microsoft Teams, but
     shows only a black screen.

   * What outcome did you expect instead?
     The virtual camera device should show the configured scene from
     obs-studio.
