This is guide howto install OBS Studio 31.1.2 [stable] on Fedora 42/41 [Xorg or Wayland support]. OBS Studio is free and open source software for video recording and live streaming. I use here Snapcrafters (Snap) version of OBS Studio, which is community-supported modified build of OBS Studio. Screen capture in a Wayland session is at least available edge channel, in video I test to use NVIDIA NVENC with Xorg (X11) / XWayland.
