[Support] DAL plugin not loaded and not shows up in any apps #183

Closed czhowl closed 4 years ago

czhowl commented 4 years ago

After install the package, OBS has the option to start virtual camera, but none of the video apps(tested in Quicktime, Photobooth, Zoom, Chrome) have the option of OBS virtualcam. I tried remove /Library/CoreMediaIO/Plug-Ins/DAL/obs-mac-virtualcam.plugin and reinstall with no luck. I also didn't get any messages in Console.app by searching obs-mac-virtualcam.

To Reproduce Steps to reproduce the behavior:

  1. Install OBS 25.0.8
  2. Install obs-mac-virtualcam-3ca8f62-v1.2.0.pkg
  3. See error

Desktop

Uhhhmmm... Did you restart your computer? I don't think I've seen that one before 😄

czhowl commented 4 years ago

Yes I have tried reinstall and reboot on different versions of packages and none of them works.

I also tried coremediaio-dal-minimal-example and that works on my system.

I'm running into the same issue. Worked fine a couple of days ago. No system changes that I'm aware of. No crashes/errors either. Virtual Camera just not showing up as a camera option anymore.

OS: 10.15.5 OBS: 25.0.8 The current release of Virtual Cam

In my case at least this is confirmed to be a library validation failure. I'm trying to use it in Microsoft Teams:

Library Validation failed: Rejecting '/Library/CoreMediaIO/Plug-Ins/DAL/obs-mac-virtualcam.plugin/Contents/MacOS/obs-mac-virtualcam' (Team ID: 62G85M9ZN5, platform: no) for process 'Teams(2482)' (Team ID: UBF8T346G9, platform: no), reason: mapping process and mapped file (non-platform) have different Team IDs

Initially, it appeared to be a global issue (missing camera) but It's clear that it's occurring in all apps which try to use the camera.

Here are the ones I tested so far:

Microsoft Teams Microsoft Edge (Chromium) Apple Photo Booth

I think we need to differentiate here: If you get nothing in none of the apps (including Google Chrome), that is a problem we don't know anything about yet. If you do get something, for example error messages in Console.app or a working virtual camera in Google Chrome (@danielsegan please test this) you'll have a Library Validation problem, to fix this see https://github.com/johnboiles/obs-mac-virtualcam/wiki/Compatibility#apps-dont-allow-dal-plugins

Seeing the same problem with OBS virtualcam not showing up in Microsoft Teams as well as DIscord. Tried the DAL signing tips but no luck. Here's the error on a fresh OBS install

After a bit more testing, the plist seems unnecessary. The following two commands fixed both Discord and Teams.

sudo codesign --remove-signature '/Applications/Discord.app/Contents/Frameworks/Discord Helper (Renderer).app/Contents/MacOS/Discord Helper (Renderer)'

sudo codesign --remove-signature /Applications/Microsoft\ Teams.app/Contents/Frameworks/Microsoft\ Teams\ Helper.app/Contents/MacOS/Microsoft\ Teams\ Helper

DavidTNguyen commented 4 years ago

I have similar setup as @czhowl. The following command fixed it for me. This is based on the instruction from the repo's wiki

sudo codesign -f -s - /Applications/zoom.us.app

Thanks that solved MS Teams for me. Had restarted but still no luck until running this command.

I have the same issue of not seeing the virtual webcam in Hangouts, Zoom and Teams.

sudo codesign --remove-signature /Applications/Microsoft\ Teams.app/Contents/Frameworks/Microsoft\ Teams\ Helper.app/Contents/MacOS/Microsoft\ Teams\ Helper

and

sudo codesign -f -s - /Applications/zoom.us.app

did the trick for me. Thanks @grantwall and @DavidTNguyen !

I wonder how could I fix Hangouts?
