OBS Virtual Camera may affect built-in webcams #3555

Open Cloudmage opened 3 years ago

Cloudmage commented 3 years ago

Using OBS virtual camera in Microsoft Teams able to use teh power of OBS, however on subsequant uses following a reboot of the laptop the inbuilt camera is no longer available on the device. Its being uninstalled or wont load properly.

This has happened on several devices, Lenovo and HP.

Platform

Operating system and version: Windows 10 1909 OBS Studio version: 26.0

Expected Behavior

OBS virtual camera should allow the selection of cameras (inbuilt/external) but also allow them to be accessed via additional applications such as Microsoft Teams.

Current Behavior

OBS is holding the cameras after it has been closed and the only choice available for other applications in the OBS Virtual Camera. In Device Manager the internal camera is now show as uninstalled and trying to reinstall with updated drivers does not work Uninstall of OBS does not solve this as the uninstall is not removing everything.

Steps to Reproduce

  1. Install OBS 26.0 on a laptop with an inbuilt camera, MS Teams
  2. Run a Teams meeting using OSB virtual camera
  3. Reboot laptop - internal camera now missing in Teams

Additional information

This has happened to several people all using different hardware.

WizardCM commented 3 years ago

What does Device Manager say about the device?

Cloudmage commented 3 years ago

Said it was uninstalled. Tried to reinstall the camera and now its not showing at all. I should have copied out the error, but cant get back to it now.

Cloudmage commented 3 years ago

Found the device in device manager now - says

" Currently, this hardware device is not connected to the computer. (Code 45) To fix this problem, reconnect this hardware device to the computer."

Its an internal device and is already connected. latest drivers have been installed.

My thinking is that the OBS Camera is using something that the inbuilt cameras need and has taken the priority on it.

WizardCM commented 3 years ago

If you uninstall OBS, then uninstall the real device in Device Manager and reboot, does that help?

I'm booting up my laptop now to try and reproduce.

Cloudmage commented 3 years ago

tried that. no still the same. Not sure if OBS is leaving something there. Windows install not removing everything

WizardCM commented 3 years ago

The general rule is that OBS only "uses" webcams if OBS is open and the camera is selected in the "Video Capture Device" source. Otherwise, it has no context of such devices. Once uninstalled, it cleans itself up and as of OBS 26 also removes the virtual camera that contains the OBS output.

Cloudmage commented 3 years ago

After an uninstall I still have a desktop icon and obs-virtualcam-module64.dll is still present in c:\Program Files\obs-studio\data\obs-plugins\win-dshow\

Edit - another process has this DLL - Probably as Teams is open - will try again with everything closed down.

Tried a reinstall first to then do an uninstall to check it removed all - OBS has said - "OBS files are being used by the following applications: Skype of Business, Microsoft Teams Please close these applications to continue setup."

There is no checking on the uninstall that another process has the DLL. Just assumes it has uninstalled correctly - only a reinstall.

The OBS Virtual Camera is not the selected camera, but does appear on the dropdown list in Teams. I havent selected it in Skype at all.

Cloudmage commented 3 years ago

after removing obs, still unable to get the internal camera active again

Fenrirthviti commented 3 years ago

Unfortunately, I don't think this is anything OBS is doing. We don't interact or affect other devices on a system, and the virtual camera is entirely self-contained. This sounds like an issue with the system itself, especially if the issue is present after OBS is removed and the virtual camera dlls unregistered. I'll leave this open though as there is no conclusive solution, and if there is something on our end causing this, we should certainly fix it, I am just not even a little sure where to begin.

Cloudmage commented 3 years ago

@Fenrirthviti @WizardCM Thanks for looking into this. Im going to look at a rebuild of the system ground up and try again. A collegue of mine did experience similar issues when their camera also went. They had two camera (front and back on device) and its the main one at the front that dropped. Ive asked them to post some details here.

Appriciate the time spent looking into this though.

WizardCM commented 3 years ago

I have tested this on my Surface Book 2 which has 2 cameras and so far neither has disappeared. I'll keep an eye on it, and additionally I'll test on a couple laptops this upcoming weekend. At the moment, I agree with Fenrir that it's unlikely that it's caused by OBS - maybe a Windows update of some kind?

WizardCM commented 3 years ago

I spend 2 hours with a user on Discord yesterday who came in with the same issue. The system had trouble recognising his webcam (also a Lenovo laptop), though it would work for a few seconds it'd disappear from Zoom, and Device Manager would report that the "Device Descriptor Failed". In my experience this usually means the device couldn't get enough power to properly communicate with the system. A System Restore to before OBS was installed did not restore functionality.

For anyone having this issue, please provide the following:

Windows Release Version: (2004, 1909, etc - Settings -> System -> About -> Windows specifications) Device ID: USB\VID_xxxx&PID_xxxx (can be found using Device Manager -> Details -> Device instance path) Laptop Brand/Model: Camera Model: (can be fetched from Device Manager or via USBView) Device Manager Error: (this could be a variety of errors, visible on the General tab under "Device status") Apps Tested: (Zoom, MS Teams, Skype, Discord, etc)

Windows Release Version: 1803 Device ID: USB\VID_046D&PID_082D&MI_00\9&24CEEA53&2&0000 Laptop Brand/Model: Fujitisu Camera Model: Logitech HD Pro C920 Device Manager Error: none that i have seen Apps Tested: Zoom, Teams (fat app, online), MS Camera app,

So i have uninstalled OBS Studio Pro, took the uninstall.bat file from this repo and run that, I still have "OBS Virtual Camera" in Teams and MS Camera App. Oddly only Teams fat-app and Camera fail when i switch from local laptop camera or OBS Studio to the logitech USB camera. Zoom, Teams online (any web-based camera) all work fine. So something has upset Teams and makes it "glitch" and restart the teams fat-app.

Any help appreciated. thanks

WizardCM commented 3 years ago

@nicholas-cross-fujitsu If you uninstalled OBS before running the uninstall.bat file, it won't successfully uninstall the virtual camera. You either have to manually unregister the DLL, or re-install then go to the C:\Program Files\obs-studio\data\obs-plugins\win-dshow and run the uninstaller that's automatically in there.

but i get a return code 3. LoadLibrary failed

Though this did remove the "OBS Virtual Camera" in teams.

Windows Release Version: 2004, 64bit Device ID: USB\VID_1BCF&PID_2C01&REV_6503&MI_00 and USB\VID_1BCF&PID_2C01&MI_00 Laptop Brand/Model: Dell Inspiron 7566 Camera Model: built-in one, _SB.PCI0.XHC.RHUB.HS12.CAMB Device Manager Error: I fixed the issue already Apps Tested: Everywhere (Meet, Discord, OBS, Windows app called Camera, troubleshooting, Device manager, etc etc) BIOS (after update mentioned below): DELL Inc. 1.0.4 I'm attaching my DxDiag: DxDiag.txt

So after OBS installation of 26 version (I was still on 25) last week my built-in camera got disabled. It was physically visible in Device Manager (only after "Show hidden devices" turning on), but disabled there, with "Enable" grayed out. However, new OBS Virtual Camera popped out everywhere in its stead. Support wrote something like "we don't have repro, it's rare, you won't be able to fix it".

But I did fix it after lots of struggling, installing drivers, reinstalling, updating everything, deinstalling/reinstalling OBS, troubleshooting dozen of times, updating even BIOS. I was about to reinstall my entire system. I was also convinced 3rd party app can't meddle with BIOS, but here we are - I finally checked if there are any camera options in BIOS, since it's built-in my laptop. And yes, indeed - camera was disabled in BIOS. Simple turning it on solved the problem. Rhetorical question, should OBS meddle with that?

//Edit: I've found a screenshot I made right after the issue occurred. 2020-11-24_10h46_20

What the Error message says in Polish is that "this particualr device isn't connected to the computer (code 45). To fix the issue reconnect the device to the computer".

Symptoms: Not as severe as posted, but cannot use cameras for which I have a source defined in in any Scene in OBS when OBS is running, even when that source is not selected/active. Deleting the source from OBS releases the camera for use by other apps.

nicholas-cross-fujitsu commented 3 years ago

Update on my issue. Seems a Global Policy setting added

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows Media Foundation\Platform
EnableFrameServerMode=0

removing this entry and all was back to normal. Thus NOT an issue with OBS.

nicholas-cross-fujitsu commented 3 years ago

What about OBS studio adding it? if it worked before, it means that obs added that.

As said it was a Global Policy setting, this means it was applied via Active Directory Security Policy settings. (not a local policy setting by a user at the keyboard or an application)

Symptom : The usual option of USB 2.0 HD UVC WebCam is changed into OBS Virtual Camera and i can't change it because in device manager the webcam is now hidden

Uninstall built-in webcam and then reboot make the built-in webcam disappear, and uninstalling OBS virtual camera still doesn't resolve the issue.

Is there anyone that can help me ?, i already tried several "fix" in this topic but some of it can't be done because the option is doesn't exist.

The fix i already tried

The only last thing that i didn't do is reset my pc, or do i miss something ?

The fix i already tried

  • Troubleshoot and Reinstall hardware
  • Registry editor EnableFrameServerMode
  • BIOS camera switch ( unfortunately there's no option for camera on my BIOS )
  • Third-party software ( already ask the tech support from ASUS and they said the driver will be installed with windows update )
  • Using restore point when i installed OBS

The only last thing that i didn't do is reset my pc, or do i miss something ?

Resetting of PC is also didn't work, I try it already

I think the Obs Dev is sleeping It's been more 6 months from opening of this thread still no fix 🙄

@ExceptionRegret As far as I know, none of the active contributors have been able to reproduce this issue or determine what is causing it. I don't see how we can produce a fix for something we haven't been able to reproduce or isolate. While I understand that you may be frustrated, comments like this do nothing to help us actually resolve the issue.

The code for the macOS and Windows virtual cameras are so vastly different that I do not believe the issue you're having is the same as the one described in the original post. If this is happening to you on macOS, I encourage you to meaningfully engage with us on our forums or Discord about what has occurred in your case and perhaps we can determine if it's at all related to this GitHub Issue or if it is an entirely new problem that needs a separate GitHub Issue.

As for this issue, I'm inclined to believe that certain Windows systems disable their built-in webcam after detecting the presence of the OBS Virtual Camera, and then never recover from that state even after the OBS Virtual Camera is uninstalled. I have no idea why that would happen though, and without an affected system to examine ourselves, I'm not sure we're able to find out.

johnxramsay commented 3 years ago

Same issue. Toshiba Qosmio A-70 running latest Windows 10 Home Edition. Inbuilt web cam working perfectly until OBS 27 installed. Worked fine with Zoom until reboot then no camera detected. Same errors as other posts above. Despite claims of of no-fault by OBS dev team OBS has made a system change that prevents my laptop from detecting the camera is installed. Deleting OBS, rebooting, updating drivers - no solution. Now left camera-less in a work from home Zoom environment. Tried the suggested registry and bios fixes listed above but it made no difference.

johnxramsay commented 3 years ago

Camera issue reported above resolved by deleting the camera in the Windows device manager and then rescanning for devices. Windows then detected the camera and all is back to 'normal'. It is still a mystery why this happened after installing OBS, using OBS and Zoom for a few days without issue and then 'losing' the camera after rebooting the laptop!

WizardCM commented 3 years ago

@johnxramsay thanks for the update. Unfortunately we have gotten no closer to figuring it why this could possibly occur, but every report helps us figure out how many people it affects and how.

crazy-canux commented 2 years ago

got the same problem.

hefalump commented 2 years ago

I too, have this issue. Discovered last night when trying to make a video call through messenger on Facebook. The camera settings give the option of OBS Vitual Camera and the inbuilt camera. I can select the inbuilt camera from the drop down but the save button will not "save" the settings. Settings in mesenger show the OBS logo. Since I last used Facebook messenger for a video chat, I am using Windows 11 and also Microsoft has released Teams! Un-installing OBS and a restart did not fix this issue.

You just only uninstall only OBS. I Uninstall the OBS and I did factory reset my entire Hard Drive and Reinstall Operating System, but still no fix for it.

johnxramsay commented 2 years ago

Uninstall and reinstall OBS will not fix it. I had to remove my camera device from windows control system devices and then reboot. Windows detected the camera as new hardware and reinstalled the device. Worked fine with OBS, Zoom etc after that. Good luck!

My wife is using OBS studio and after the latest update the webcam on the apple cinema display is not working. It has completely disappeared. She is running an AMD build with the latest win10 update and latest OBS studio. Removing virtual obs cam did not work, and removing obs did not work either. So from the comments here it seems like OBS made an oopsie somewhere. Anyone with insight into why the OBS virtual webcam takes over all other webcams? Any insights into why other webcams are being disabled?

My wife said she needed to make the video size smaller, so she went to youtube and followed some guide to change settings in OBS from MKV to something else and after that the webcam broke. This was the video: https://www.youtube.com/watch?v=ei7UN830lFs&t=80s

binhpv commented 2 years ago

I encounter this issue as well, though for me it's an external Logitech webcam so unplug and plug in again make the camera appear. So just in case you have external camera, try unplug as a workaround

theomason22 commented 2 years ago

I've had OBS installed for months with no issues. I may have accidentally clicked the virtual cam but honestly I'm not sure. I just wanted to do a quick recording before a work thing. anyway camera is now disabled and i've tried all of the solutions to this except for going into the BIOS cause that kinda scares me. I can research issues but i'm not a tech guy

I've recently had this issue. Downloaded OBS to record some videos. In my particular case, I did not close the program, but just closed my laptop and it went into sleep mode. After that, I tried using my camera and it wasn't recognized, only the OBS virtual camera, which is my screen.

Since OBS installation no major updates have been installed on my machine. Would be awesome to get a solution for this, I use my camera a lot and haven't been able to do so for a while now. I see this is now a recurring issue, would be nice if OBS devs see this and prioritize it.

Sunny-Greg commented 2 years ago

So it looks like it's been over a year and there's still no definitive solution to this issue. I have also encountered this on an HP computer running Windows 10. Not only does OBS only give the OBS Virtual Camera as an option, but all apps that would use the built-in camera no longer have access to it. It's scrubbed thoroughly from the system. I cannot even uninstall the camera software because I can't see it anywhere in Device Manager.

Seems like geb88, with his BIOS solution, might be the only person on the right track. I'm going to give it a try later, but for now I'm commenting to add to the pile of people waiting for a clearer fix. If the problem is how the system responds to OBS, then what can OBS do to not trigger this response?

Fenrirthviti commented 2 years ago

We're still closely tracking this, but unfortunately, we have not been able to replicate it internally.

Right now, the thing we need is access to a system that has the issue to do some investigation/troubleshooting. If you are willing to work with us, please send an email to contact@obsproject.com so we can set up a date/time to do a remote session where we can investigate what is going on. This should be on a system you are comfortable with one of our developers accessing remotely and installing debugging software (it can be removed afterwards).

MBR5 commented 2 years ago

I'm not sure if anyone would be comfortable with that, to be honest. I myself wouldn't, I use my computer for studies/work and heavily rely on it. This makes a solution more urgent, and hoping for someone with this issue to contribute might not be the best approach. Do you think setting a due date for someone to show up would help, or do you propose a workaround for this?

Fenrirthviti commented 2 years ago

We don't know what's going on with it, and everyone who experiences the issue is not willing to let us take a closer look, so there is not really much we can do. We have spent months trying to replicate the issue on our end so we don't need another system, to no avail. Debugging OBS would be a non-destructive act, it poses very little, if any, risk to your system, and any debugging software will be cleanly removed after we can take a look.

Without access to a machine that has this issue, there isn't really anything we can do. We simply don't have enough information on what might be causing it to even guess at a solution or workaround.

Fenrirthviti commented 2 years ago

As a side note, this also seems to only affect systems that are company issued or work-related, so there might be some kind of enterprise software that is causing this problem we just don't have ready access to.

aeshirey commented 2 years ago

I'll chime in now that I have hit this. I installed OBS for the first time today (have never used it before) on my personal machine not linked to an Active Directory. My camera has worked without any issues for years. I setup OBS, did some testing, closed OBS and reopened a few times while playing around, and after the third or fourth time opening, I noticed that it wasn't picking up my video input. The standard Windows Camera app couldn't find my device.

While @Fenrirthviti said:

We don't interact or affect other devices on a system, and the virtual camera is entirely self-contained. This sounds like an issue with the system itself, especially if the issue is present after OBS is removed and the virtual camera dlls unregistered

the fact that my camera suddenly stopped working maybe an hour after installing OBS would seem a very odd coincidence for it to not be caused by this installation. I'll also note that in playing with OBS, I setup some keyboard shortcuts to mute/unmute the video input device, and I have also found that my Greenshot screen cap program is not responding to its pre-set keyboard shortcuts anymore. Maybe it's unrelated, but again it would seem a bizarre coincidence.

I went into the Device Manager and found:

There was no apparent way to fix this within Windows. Restarting didn't do anything.

For what it's worth, though, I did go into my BIOS to check the settings, and while it has no settings for the built-in camera, I selected "Discard Changes". (I made no changes myself, but why not try?) When I got back into Windows, my camera worked again.

Fenrirthviti commented 2 years ago

To be clearer on my comment there, I'm not saying that it's not possible we're triggering some kind of system issue, but as our virtualcam doesn't reach outside itself, it's very difficult for us to understand what is happening.

It will be almost impossible for us to move forward with this issue without direct access to a system that has the issue to do further debugging to understand what is going on. See: https://github.com/obsproject/obs-studio/issues/3555#issuecomment-964700670

MBR5 commented 2 years ago

Hi @aeshirey! Is it possible you could guide us into how to 'Discard Changes' from the BIOS, to see if it is possible to do so after some time has passed with the camera being disabled? Would very much appreciate it.

TrickyWhiteCat commented 2 years ago

So I have a HP Pabillion Gaming laptop with pre installed windows10. I installed obs, nothing goes wrong. I update it to windows 11 and roll back to windows 10 a few time and install the same version of obs (from the same installer that I have on another disk) and everything worked perfectly fine. Then I swap the boot drive, install windows 10 on it and the obs didn't kill my webcam, but when I update it to windows 11, the webcam was killed (since I didn't use the webcam regularly, not sure if it's obs's fault or not but because obs was installed on my laptop and no solution I tried work (for me and for other people on this thread), I think it may be obs's fault. The point is it's weird because I have the same system, same version of obs with several versions of windows installed and the problem only occurred once.

Search <Your PC's manufacturer (Dell, Asus, HP,..) > bios function key and then restart the computer, continuously press that key on startup to enter the BIOS setting. Use the arrow key to navigate around and change whatever setring you want (with the keyboard) and then navigate to the last column (by pressing -> key and choose "discard change" (or save change if you know what you have just done)

MBR5 commented 2 years ago

Awesome, thanks @aeshirey! My update is that now the camera works for around 10 seconds during startup. After that, it just turns off and the previous message (0xA00F4244. Camera not found) is shown again. Hope this helps.

geb88 commented 2 years ago

For any of you who are afraid entering BIOS like I did - looking and navigating in it isn't dangerous. It may look scary though (especially on PC with MSI boards xD) but untill you save anything (a specific key) you are safe to look around. Don't save the changes if you don't know what are you changing though!

As an update, the issue didn't happen again even though I did finally install the newer version of OBS. Once fixed it stays fixed.
If I had to guess which other app might interfere with OBS I would definitely point at Discord. I know what it can occasionally do to my cablefree Sennheiser headphones and it sometimes interfere with Meet on Firefox.
