[Support] WhatsApp Client Support

[eazyAlf]

Describe the issue
There is a new feature within the WhatsApp Client on macOs that allows usage of webcam now.
I've tried with re-codesign the application and it worked, for a bit. Don't know if there has been an update or if it could be related to disabling SIP, but since today I can't use OBS Virtual Camera within WhatsApp anymore.

I've tried everything I could and the only thing i found out as a workaround is, that once I open the WhatsApp Helper (/Applications/WhatsApp.app/Contents/Frameworks/WhatsApp Helper.app) I am able to use it, but the resolution/renderer won't load properly.

To Reproduce
Steps to reproduce the behavior:
Set up the OBS Camera as your camera – with the call starting all I'll see is a black screen, once the call is answered, WhatsApp tells me my camera is not supported and I should contact the support (which wasn't helpful)

Behavior
Not sure what it was related to, but since I've had problems in Telegram I disabled SIP, since I've disabled SIP, Telegram is working fine.. but now neither WhatsApp nor Photoboot (which were working fine before, only by re-codesigning the main application, doing nothing with the helpers) I have this issue.

Screenshots
Camera is visible:

No Preview available:

When Helper is started instead:

Desktop (please complete the following information):

• OS version: [e.g. macOS Catalina 10.15.6]
• Application: WhatsApp Client / electron application
• Virtualcam version: v1.2.1
• OBS version: 26.0.2

Hi, could you please fill out the template?

@gxalpha – sorry.. just did. My first issue I am reporting.

Most likely, WhatsApp has moved plugin loading to a separate process for security reasons (This is what Zoom and Chrome do). Try re-codesigning WhatsApp Helper.app and maybe looking around in the WhatsApp.app for other processes you might need to re-codesign.
