Linux Releases

Option 1 - Flathub

flatpak install flathub com.obsproject.Studio.Plugin.DroidCam

Option 2 - Manual Install via zip file

The DroidCam plugin releases are made to be generic and mostly self contained. The main dependency is ffmpeg.

You may check which FFMpeg version your system is using, and download accordingly.
Releases that are labeled "Flatpak" should be compatible with your system as long as the ffmpeg version matches.

Specifically, it is the libavcodec package that matters:
libavcodec58 == ffmpeg-4
libavcodec59 == ffmpeg-5
libavcodec60 == ffmpeg-6
...
