Video Camera in Safari shows "Bib Bop" Mock Video

thanks a lot for troubleshooting this annoying bug. but I can't find anywhere ""Use Mock Capture Devices" on safari, on the develop menu or elsewhere

I finally fixed it permanently after 2 years without camera and mic in Safari!

Here's how:

1. Set full disk access in MacBook privacy settings for "Terminal" (I tried also for "defaults", but don't know if that matter)
2. In Terminal type:

• • "defaults write com.apple.Safari WebKitMockCaptureDevicesEnabled 0" and
  • "defaults write com.apple.Safari WebKitPreferences.mockCaptureDevicesEnabled 0"

1. You can read your current settings using this command "defaults read com.apple.Safari"
2. Restart Safari
3. And that's it!

Hope it helps

I tried 100 YouTube videos. Try all the commands in the terminals. I didn't find these options in developer menu as well. For 1.5 years I cannot use my camera on Safari browser only..it works fine in all other applications. even I am not able to use the microphone as well.whenever I try to give voice commands over YouTube nothing happens. I tried to contact Apple as well they are saying delete the current account and make a new admin account. In the new account everything works fine.I cannot delete my current account coz everything is here only all my Java paths and settings.i am not getting the option to reset safari..all I can see is delete cache and extension. der should be some sort of reset functionality for safari.if someone finds it kindly help me out.i am attaching the screenshot as well.

Sorry folks I had forgotten to mention you need the debug menu active

you need admin rights and paste this in a terminal window (cmd + space + search terminal)

defaults write com.apple.Safari IncludeInternalDebugMenu 1

you should be able to see the option and turn it off

Hi no it is not resolved at all.

and Tom's solution ( It's a Safari setting in Develop > WebRTC that was causing it. Deselect "Use Mock Capture Devices" for that option and that solves the problem) is not valid with the current version. WebRTC is no longer in the develop menu.

I tried different commands in Terminal I found on various forums or on ChatGPT but none work.

so I am totally stuck with that since Safari is part of the system and cannot be reinstalled/reset independently. I tried to reinstall the system too but same result.

FINALLY MY ISSUE IS SOLVED !!!!! but temporary..let me simply go step by step in a clean manner

Step1:Enable developer menu. (safari>settings>Advanced>click on show features from web developer.

Step 2 : Disk excess to the terminal.(system setting>privacy and security>full access disk>selected terminal)

Search the terminal in the application and type this command (defaults write com.apple.Safari IncludeInternalDebugMenu 1) without brackets

step 4:restart safari and debug menu enable

step 5:selecet debug menu>Webkit Internal features>disable Mock capture devices.

i write temp. because when I restart the safari it goes back to enabled mock devices..edwardfromparis anyhting to say about this?

Sorry, just found it! Here is the screenshot on how to find it!

We have the same version

you need to have sudo access. (Admin)

You also need to make sure your terminal app has full disk access

in terminal type you will be asked to type your password.

The keys typed will not be shown so do it slowly. Then press enter.

sudo defaults write com.apple.Safari IncludeInternalDebugMenu 1

if this does not work I would not know how to fix it... sorry

no it is not resolved.

there is no WebRTC menu anymore in safari 17.4.1.

and the same happens with Teams if you open the conference call on Safari. exactly the same issue.

so if anyone has an idea as to how those mock video and audio can be disabled, it would help a lot

@Edward thanks a lot for trying to help. but when I enter this command in Terminal, I get:

Could not write domain /Users/xxx/Library/Containers/com.apple.Safari/Data/Library/Preferences/com.apple.Safari; exiting

so that I why I wonder if we are using the same version of safari; mine is 17.4.1

what is yours?

finally, my system is working properly thnx edward and the audio for YouTube is as well..but until I restart my Safari browser current version 17.5 and OS venture 14.5 M1 air.I couldn't find com.apple.safari.plist in library>preferences

this is the develloper menu I can see:

Hello,

I have the same issue, but I can't find the settings you mentioned. Could you please post a screenshot please ?

I'm on MacBook Air M1 and latest OS
