Virtual camera not working

[lucouto]

I've just run the script and installed OBS successfully on my M1 Mac mini. But the Virtual Camera in not working. When I click "Start Virtual Camera" the button blinks and doesn't activate.

Any easy way to debug this, please?

TIA, L.

I've just tried this for the first time and the virtual camera won't start for me either. I'm on a new 14" Macbook Pro with M1 Max (24-core).

Compiled this few days ago, I've got the same issue. If I click on the "start virtual camera" button it does nothing. I'm on a MBP 13 with M1

Can you please run this command and provide me with the output?

find /Applications/OBS.app -name *virtualcam*

I just compiled it and when I run the find command I get zsh: no matches found: *virtual*

Here is log from running the install script - https://gist.github.com/ambirex/bbc444186fcd0933cb974245ffc3c9d9

edit: I realized you were missing the quotes so if I run find /Applications/OBS.app/ -name "*virtualcam*" I get:

/Applications/OBS.app//Contents/Resources/obs-plugins/mac-virtualcam.so

Reading from this forum: https://obsproject.com/forum/threads/fyi-macos-virtual-cam-on-obs-26-1.135468/

I tried to:

• create a new user, log in from it, turning on virtualcam and going back to my main account -> didn't work
• copying the virtualcam plugin file in
  • /Library/CoreMediaIO/Plug-Ins/DAL/
  • /Library/Application Support/obs-studio/plugins in both folders and in every single folder, I tested every time, the only change I noticed is that the button is clickable, but the system don't recognize the virtualcam(even with app signatures as well)

Results from find /Applications/OBS.app -name *virtualcam* here:

/Applications/OBS.app/Contents/Resources/obs-plugins/mac-virtualcam.so /Applications/OBS.app/Contents/Resources/data/obs-plugins/mac-virtualcam /Applications/OBS.app/Contents/Resources/data/obs-mac-virtualcam.plugin /Applications/OBS.app/Contents/Resources/data/obs-mac-virtualcam.plugin/Contents/MacOS/obs-mac-virtualcam

There were some warnings during the compilation process. Maybe the log can help you debug this. install_log.txt Terminal Saved Output.txt

I had this same issue. For some reason, there's no /Library/CoreMediaIO/Plug-Ins/DAL folder after running install.sh.

I was able to get things working by manually copying the virtualcam plugin:

sudo rsync -ahP ./obs/cmake/_CPack_Packages/Darwin/Bundle/obs-studio-x64-27.1.3-modified/OBS.app/Contents/Resources/data/obs-mac-virtualcam.plugin/Contents/ /Library/CoreMediaIO/Plug-Ins/DAL/obs-mac-virtualcam.plugin/Contents/

Tried this solution and it works! Don't know why when I copied the whole .plugin file in the DAL folder didn't worked, but copying the Contents folder inside did the job. Thanks

I can confirm that manually copying the files from OBS.app to /Library/ fixes the Virtual Camera issue. sudo rsync -ahP /Applications/OBS.app/Contents/Resources/data/obs-mac-virtualcam.plugin/Contents/ /Library/CoreMediaIO/Plug-Ins/DAL/obs-mac-virtualcam.plugin/Contents/

Having a similar issue with the native M1 build. Starting Virtual Camera works fine, just doesn't show up anywhere in the system for me to pick.

/Library/CoreMediaIO/Plug-Ins/DAL/obs-mac-virtualcam.plugin/Contents/ has the correct stuff in as well. Thought it might be a codesigning issue and re-signed the App but that didn't do it either
