This question might already exist the answer, to be frank, wasn't very helpful, and the only answer was a response to a comment the author made. As far as I am concerned it's not a duplicate of this question because the original problem was unlikely because of the firmware.
I have been looking for a solution to this problem for at least 45 days. I have tried the proposed solutions on the Skype Community Forum, the search results using Process Explorer, indicates my camera should be working.
This problem happens when both my Logitech and Lifecam Studio are connected. I have tried amcap, but the program doesn't seem designed to work with a 64-bit operating system. I use the Webcam Diagnostics I found on the same website, and everything checked out.
My camera was working at some point in the last year, this problem is recent ( at least 45 days ) I just can't figure out the cause of my problems. I have also tried booting with only required services, and the problem still surfaced.
Let's start with the basics. When I attempt to view my video settings, I get the following message:
Can't start the video. Try closing other programs that might be using your webcam.
vid search results:
But the device is working properly:
I should add the following. I am indeed running Windows 8. I loaded up a virtual machine with Windows 8.0 and Skype video worked without a problem. So there is something that has been installed or running ( despite the process explorer results ) causing the problem. I just can't figure out how to find it.
If the community does not come up with something, and the update to Windows 8.1 does not resolve it, I plan on buying a Premium subscription to get technical support from Skype/Microsoft. If that happens and my problem gets resolved, I will post the solution for the community. I am hoping we can find the solution together.
Did I mention the Windows Store Camera application works on both the host operating system and the guest operating system? I was even able to Skype with myself using the desktop application on the virtual machine and the Windows Store application on the host operating system
Out of curiosity, I installed ManyCams, and after I removed the toolbars, that were installed even after I declined to install them, it gave the same error. ManyCams support hasn't been very helpful. There is no diagnostic mode. I used Autoruns to boot to a minimal configuration, and the error still surfaced. Procmon didn't register any failures with Skype.exe itself. I have an open dialog with ManyCams ( their advice sucks, but it's free ).
I found another duplicate with a non-accepted answer. The user didn't indicate if the solution worked, but I have already tried that, and it didn't work. Since I have an ASUS ROG ( Republic of Gamers ) motherboard, I will request their community for assistance also.
I should mention I used Acronis True Image 2013 Plus Pack
back in June/July timeframe to migrate my legacy system to my new hardware. I am not exactly sure if I attempted to use Skype (right) after the migration, I just know the problem has been around, for at least 45 days. My legacy system was running Windows 8. My current system is running the migrated installation of that same Windows 8 installation. This isn't the source of the error.
This problem surfaces with any web camera. I originally had a Logitech product. I noticed this problem a few weeks ago, installed the current drivers, and still had the problem. I purchase the Lifecam Studio in an attempt to solve this question. When first installed the drivers were the most current drivers. Both the Logitech and Lifecam Studio have the current firmware and drivers.
So I thought I had something when I discovered the following unsigned drivers. This turned out to pretty much nothing. I will be turning on the logging capabilities of Skype to see if I can capture a hardware event. The driver problem has been since resolved, and those six drivers now are signed.
In response to a theory I and Dave Rook had about having an Intel® HD Graphics 4600
and ASUS GTX 770 DirectCU II
installed I have since uninstalled the Intel® HD Graphics 4600
from Add/Remove Programs
sadly the Intel® HD Graphics 4600
isn't listed in the device manager so if that's the problem I am in trouble. While a good theory, this is unlikely the cause of the problem.
This is also an update based on a comment I made earlier. The Windows Store applications cannot be classified as your traditional 32-bit or 64-bit applications, while their process might be 64-bit or 32-bit, they are required to use entirely different WinRT drivers and library files. For instance, I know for a fact the Windows Store Skype application does not use the VC++ drivers, which are the exact drivers I suspect are the cause of this problem. Both the 32-bit and 64-bit VC++ drivers used by the Webcam are unsigned. While this could be a driver issue, it's both 32-bit and 64-bit drivers, at least until I can find a 64-bit desktop application.
Some additional details that I forgot to provide. My motherboard is a MAXIMUS VI EXTREME, and during the first week of using my new computer after I confirmed everything else was working I installed all the included software installed by AI Suite 3
So does anyone have an idea on how to solve this infamous error?

Hm... Why is this post a community wiki? If the reason is an extreme score, then why not make this a wiki post too? Both posts have extreme score. "After the 5th round of serial downvoting of your questions you learn some tricks." - have you ever wondered why is it downvoted? Votes mean that something is wrong with the question or with the asker.
– None – 2018-01-04T14:41:54.943@ThePirateBay - I wanted this question to be a community wiki. Hard to improve a question, when 29 people, fail to indicate the reason they downvoted the answer. As to the tricks I mention, I just refuse to ask questions, as this user profile. The question is specific, it has a very specific solution, and the problem extremly detailed – Ramhound – 2018-01-04T16:16:42.200
As to the reason a highly upvoted answer is not a community wiki, that would be obvious, I don't want it to be a community wiki. This question was made a community wiki, when it was possible to convert it to a community wiki, after the question was submitted. That is no longer possible. A question could also become a community wiki, if several edits were made, I honestly forget if I specifically choose to convert this question to a community wiki or if it was converted automatically. When 29 people downvote you, for no reason, you learn you simply don't care what those 29 people think – Ramhound – 2018-01-04T16:26:31.753
I've had similar issues with sound, the problem was having more than 1 sound card. I wonder if Skype is choosing a different video card than what the OS is (hence the different results in VMs) – Dave – 2013-10-08T13:51:42.400
In Device Manager, is your webcam listed under "Imaging devices", or does it have a yellow exclamation mark ? – harrymc – 2013-10-08T18:27:07.007
My above question was low-chance, admittedly. Another test: Verify that the VM uses the same driver as your computer. Have you tried the oldest trick of deleting the device and reboot? – harrymc – 2013-10-08T18:45:04.240
Can you give more info about the differences between the VM and host? – harrymc – 2013-10-09T05:38:55.220
It's nowhere clearly stated, but my guess is that both VM & host are on Windows 8 or 8.1, that the VM is 32-bit, the host is 64-bit, Skype is 32-bit but the programs that work well are 64-bit. If that's so, then the situation is clearly the lack of 32-bit driver, which is quite a problem on a 64-bit Windows (unless in XP Mode). – harrymc – 2013-10-09T13:33:16.713
I think you stated that Skype and ManyCams both don't work and both are 32-bit. The Windows Store Camera works and is new, so I would guess that it's 64-bit. Unless you disagree, I would restate your problem to say that 32-bit programs cannot use the camera. – harrymc – 2013-10-09T13:39:33.463
Up until you find a 64-bit camera product, the 64-bit hypothesis is on freeze. Another point is the display driver. You say you have 2 video cards and that you have installed the latest drivers from the manufacturers for both. You could try the opposite - uninstall the manufacturer drivers and suites for both, put your camera on a different usb port, and reboot to let Windows install its own drivers and verify in Windows Update optional that there aren't any updates. Try desktop Skype before the Modern app. Also search the Event Viewer for interesting messages. – harrymc – 2013-10-09T19:20:14.500
