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 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.
Lets start with the basics. When I attempt to view my video settings, I get the following message:
Can't start 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 in order 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 curosity 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. Apparently 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 its 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 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 logging capabilities of Skype to see if I can capture an hardware event. The driver problem has been since resolved and those 6 drivers now are signed.
In response to a theory I and Dave Rook had about having a
Intel® HD Graphics 4600 and
ASUS GTX 770 DirectCU II installed I have since uninstall 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 how to solve this infamous error?
