I've got the same error on Droidcam and on my new webcam Logitech C922.
That error will only come if the webcam is incompatible with this software.
Even though it works into the webcam utility. But not if you click on Start.
Then it will also show a error which is:
FaceApi Tracker Error
The file could not be written.
Check if it's still opened by another program.
I just need a compatible webcam to auto rotate in-game.
Because I just wanna use it for City Car Driving to practice for my driving lessons.
I just saw on your site that the Logitech C920 is compatible though?
I'm gonna return the webcam for that one lol http://facetracknoir.sourceforge.net/compatibility/webcams.htm
Can you install FaceTrackNoIR to a different folder, preferably one you have manually created and outside the Program Files folder? It seems like faceAPI does not have permission to write a file.
FYI. the faceAPI tracker tries to write non-selected video-sources to the blacklist ...
You can also remove FaceTrackNoIR and re-install 'As Administrator'?
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
I've installed it to a different hard drive and that Face API Tracker error disappeared now.
I've returned the C922 and I've got now the C920, because I saw the C922 isn't compatible on your website in that list.
So when I click on Start the error is gone, but the API error -13 is still there if I run the file: FTNoIR_FaceAPI_EXE.exe.
The webcam still wouldn't turn on into the program, but if I try it with the webcam utility it works. I've put screenshots about it into the attachment.
I've just tried it with Manycam, but the same error code.
I've tried aswell Xsplit Vcam but same story.
I've got the Gigabyte GeForce® GTX 1050 D5 2G(rev1.0/rev1.1) using Windows 10 Pro 64bit.
I can try the onboard Intel graphics driver of my mobo which is the Gigabyte GA-Z97-D3H (rev. 1.1)
and see if it resolves the issue.

I'm trying to use Face API tracker source. No preview in FaceTrackNOIR appears. When I launch FTNoIR_FaceAPI_EXE.exe manually got message:
As said here tried to fix codecs by Codec Tweak Tool. Takes no effect. I'm using smartphone as web cam (Droid Cam). So I thought it was
in my case. I've turned off the Droid Cam app and there was the same error (I expected some different one in case of other software using the webcam).
Point tracker see web cam perfectly.
How could I fix this?

Hello Pavel,
Other users successfully use Droidcam, so I suppose it can work.
Did you give FTNoIR_FaceAPI_EXE permission to access the webcam?
Thanks for your response.
Yes, it seems like FTNoIR_FaceAPI_EXE have the permission.
Solved. I've tried it with my laptop with built-in web-cam. Everything works fine. Then DroidCam was connected and the error was reproduced.
Additionally I need to blacklist one of DroidCam source in FaceAPI config file.

This is what the FaceAPI settings looks like btw
It's strange: the C920 should work fine. Usually, when the video works in the utility, faceAPI can also use it.
In the past we have had similar reports, which later seemed to be caused by video-cards or drivers :(.
Back then, we sometimes recommended using a program like ManyCam, to function as intermediate between the webcam and faceAPI. Maybe you could try it?
BTW. Don't install the 'extras' the ManyCam installer offers...

The onboard graphics driver (Intel HD 4600) also didn't work.
