Hi Alexander,
I'm sorry but at the moment I am the only person who can try to debug this issues, and also the only maintainer of WS.
Anyway I hope that someone can give WS project an hand :)
Back to us this issue was solved by Kevin Branham in the community.
About the permission issue, I can't reproduce the issue on my Ubuntu 14.04 64bit machine, but I got it on my UbuntuStudio 14.10 x86.
Seems more a Chrome issue than WS ... anyway I will try to debug this.
Will let you know.
Thanks.

Hi Alexander,
this is what i try, and finally, got it working.

This first steps may not be necessary:
- Adding my user to "video" group --> Result: no permissions
- Installing diff packages to my working Ubuntu 64bit:
phyton3-requests
python3-urllib3 --> Result: no permissions
- Installing diff packages to my working Ubuntu 64bit:
nginx-core --> Result: no permissions
- Setting Java Permissions in control panel --> Result: no permissions

I saw that http://www.testmycam.net/ works.
Because https://jitsi.org is on a secure connection i tough that the problem was on port 443 ... but in google hangout (https connection) the virtual device works ok.

After this I uninstall Chrome Version 38.0.2125.111 and I install the deb they propose on the chrome site (version 33.0.1750.146).

Running Chrome give me a warning message, but now https://jitsi.org works.

Really don't know why this occurs.
Will try now to re-update chrome to the latest, and see what happen ...
karl.

Reinstalling Chrome latest version, the problem is back on my UbuntuStudio machine.
Maybe https://jitsi.org/ support can understand the problem.
I also tried with the virtual webcam feeded by gstreamer in a command line, without WebcamStudio, and the problem persists ... Contact v4l2loopback team is another possible help.

More tests ...
On my UbuntuStudio 14.04 x64 machine after giving the permissions, https://jitsi.org works correctly with the webcamstudio (v4l2loopback) SkyCam module, so I can reproduce the problem only on my UbuntuStudio x86 machine.
The only workaround i found is to uninstall completely chrome current version 38.0.2125.122 in this way (This will delete all bookmarks and settings on chrome):

Delete /home/user/.config/google-chrome and .config/chromium if you have it.

Purge the packages with:

$ sudo apt-get purge google-chrome-stable
$ sudo apt-get purge chromium-browser

And then installing the Chrome version 33.0.1750.146 that if you cannot find i will upload here:
https://drive.google.com/file/d/0BxkZ_wh6t7jbelBST3ZSU0FzQW8/view?usp=sharing
Don't know why I get this version when I first download it from the Chrome official page (yesterday ...) ...the successive downloads from the same official chrome page give me the latest 38 version ...
No i can't find it anywhere at the first searches ...

By installing the version of Chrome you staged on your Google Drive, (and also by removing chromium), I am happy to report that WCS is now working 100% perfectly with Jitsi Meet. Thank you so much Karl!

You welcome Alex,
it would be good to understand why this version works ... Seems that
Chrome latest works well only on my 64bit machines. I also try Chrome beta
and unstable latest version on my x86 machine without results ...
Have a good day.

From what I've seen of this issue it seems like it was probably just on Google's end. Using v4l2loopback I've been able to see my loopback stream in VLC, Firefox, and WCS itself - but not Google Chrome. But when I upgraded Google Chrome to a more current version (43.0.2357.81 (64-bit)) I can now see the WCS loopback feed in Chrome - but there's some kind of color channel issue. (Apparently, red and blue color channels appear swapped in Chrome - perhaps that should be a new ticket?)

I haven't tested the webcamstudio version of the v4l2loopback driver because, honestly, I've not had any success with it in any of my tests. Since it's very nearly the same code as v4l2loopback I'm not sure what's happening there.

Just tested in Google Chrome 43.0.2357.81 (64-bit).
I can confirm that now the WSVideoDevice (same code of v4l2loopback - only name changes) is listed in Chrome but with red/blue swapped.
If you use SkyCam (it makes a new dev/video21 via a Gst-launch pipe) and choose that, also the colors works, but for some reason works only once and if re-selected, doesn't works.
We can open a ticket on v4l2loopback github:
https://github.com/umlaeute/v4l2loopback
I can really do nothing about that.

Hi George,
I will test the new version of Chrome as soon as possible. Thanks for the feedback.
Have you try to apply the Swap red/blue filter on the webcam Stream?
If the colors get ok then it is a red/blue swap for sure.
I will let you know.

Code changes in Chrome and/or the upstream v4l2 loopback driver seem to have fixed this. Other issues are being tracked as we aim to further improve WCS functionality with Chrome.
