Option 2 - Install via zip file

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

With Ubuntu 20.04 (Focal) / Ubuntu 22.04 (Jammy), use
DroidCam OBS Plugin v1.5.1 FFMpeg-4
DroidCam OBS Plugin v2.1.0 FFMpeg-4

With Ubuntu 22.10 (Kinetic) / Fedora 36 / latest Flatpak (OBS-29) use
DroidCam OBS Plugin v2.0.1 FFMpeg-5
DroidCam OBS Plugin v2.1.0 FFMpeg-5

Other distros: check which FFMpeg version your system is using, and download accordingly.
Specifically, it is the libavcodec package that matters:
libavcodec58 == ffmpeg-4
libavcodec59 == ffmpeg-5

Consult the README.TXT in the download zip on how to install.
