On Pop_os! filter does not show up for Video Capture Device (V4L) or Media Source #95

charlesritchea · 2023-05-26T14:56:19Z

First off, the .deb installed into /usr/lib locations, but I could not get the plugin to load until I moved to ~/.config/obs-studio/plugins

After moving the plugin and locale files into the expected paths, the plugin loads as shown in the logs, but it does not come up as a a Filter option

I found this problem on Debian 12 Bookworm amd64 too.

Solution to the first problem of the plugin not being found is to sym-link it into the correct location for Debian/Ubuntu and derivative distros expected location as dictated by the obs-studio package itself.

$ sudo ln -s /usr/lib/obs-plugins/obs-virtualbg.so /usr/lib/x86_64-linux-gnu/obs-plugins/

(the Debian .deb package should install to this location).

OBS now sees the plugin and can add it to a source as a Filter but as soon as we try to add the Effect by pressing on the Effects + button OBS crashes with:

...

As said above, or at the link. I find that the video render filter works, but not the detector filter. I also get a crash with OBS. I did have to create a shortcut to the *.so file.

Tried that on LInux Mint 21.2. The plugin shows up in the terminal output when starting obs, but it doesn't show up in the filters.
