Hi joanguisado,
 sorry but WS 0.5x is no longer maintained.
You can try the SkyCam feature in WebcaStudio 0.6x to have flash compatibility 
or if you want to use WS 0.5x you can try the solution well explained by 
willyaynard in this past issue:

http://code.google.com/p/webcamstudio/issues/detail?id=81&can=1

" What I needed to do was basically the following (this should not be 
copy-pasted 1:1 as it may need personal adjustments and some required software 
may need to be installed first):

<< Install v4l2loopback module >>
su
git clone https://github.com/umlaeute/v4l2loopback.git
cd v4l2loopback
make
sudo make install
sudo modeprobe v4l2loopback

<< Run WS 0.5x and start a source >>
webcamstudio

<< Open a Terminal and type the gst-launch command line >>
gst-launch-0.10 v4l2src device=/dev/video0 ! v4l2sink device=/dev/video1

<< Open Chrome and use the /dev/video1 device >>
google-chrome

With this WS can be used on Linux Mint 15 (64-bit) with the latest Chrome 
Browser."

Basically you have to stream the Webcamstudio Module to another virtual webcam 
instance (v4l2loopback) with gst-launch in a terminal and then use the last 
device with Chrome.
Sometimes this re-streaming could flip horizontally your output, but you can 
use WS 0.5x filters to adjust the image.
Hope this helps

Thank Karl for your answer. It was very quick and most important...It almost 
worked. I'm having problems when executing this commnad:

$> gst-launch-0.10 v4l2src device=/dev/video0 ! v4l2sink device=/dev/video1

I got this error:

Setting pipeline to PAUSED ...
ERROR: Pipeline doesn't want to pause.
ERROR: from element /GstPipeline:pipeline0/GstV4l2Sink:v4l2sink0: Device 
'/dev/video1' is not a output device.

I don't know if it's due to the difference in the distributions Ubuntu and Mint 
but I don't think so since Mint is based on Ubuntu. Maybe you have some idea of 
what's happening.

Thanks again.

joan

Are you sure to use the correct /dev/videoX as input and output?
Try this command to have infos about video device in your system and change the 
command accordling to your configuration (v4l2-ctl have to be installed):

v4l2-ctl --list-devices

For a better explanation, let me show you the outputs of the commands:

$>v4l2-ctl --list-devices
Dummy video device (0x0000) (v4l2loopback:0):
    /dev/video1

WCStudio video device (0x0000) (webcamstudio:0):
    /dev/video0
$> gst-launch-0.10 v4l2src device=/dev/video0 ! v4l2sink device=/dev/video1
Setting pipeline to PAUSED ...
ERROR: Pipeline doesn't want to pause.
ERROR: from element /GstPipeline:pipeline0/GstV4l2Sink:v4l2sink0: Device 
'/dev/video1' is not a output device.
Additional debug info:

Thanks,

Ok,
 seems you have to switch video0 with video1 like this:

gst-launch-0.10 v4l2src device=/dev/video1 ! v4l2sink device=/dev/video0

because we have to stream webcamstudio video device video0 (used as output) to 
the new installed v4l2loopback (Dummy video device) video1 (input/output).
Once the gst-launch pipe is running try chrome.

Hi, would you help me have flash to recognize the pseudo camera?

The source built WebcamStudio is of version 0.72, I followed the instruction 
below to work it out:

https://plus.google.com/108633206357681875841/posts/WGx6syTrvvE

It seemed to work almost right, but I never see "WCStudio video device" button.

Here is my output of command 'v4l2-ctl --list-devices' for reference:

Dummy video device (0x0000) (platform:v4l2loopback-000):
    /dev/video21

Dummy video device (0x0001) (platform:v4l2loopback-001):
    /dev/video0

Obviously, "WCStudio video device" won't appear.
I tried any possible combinations of option and here I attatched the main 
window of WCS.

Hi, WSVideoDevice appears if you compile it.
http://sourceforge.net/projects/webcamstudio/files/Binaries/Beta/MultiDistro%20%
28Fedora-OpenSuse-Arch%29/dist_WebcamStudio072_r583_MultiDistro_150326.zip/downl
oad
I see you have dummy video device that is the one you get from original 
v4l2loopback installation.
You can use that instead of WSVideoDevice (which is a fork) and it is the same.
If you have issues, please point to :
https://sourceforge.net/projects/webcamstudio/?source=directory
... because google-code hosting is going to close.
Thanks.
karl.

Forgot to mention that is better to have only one v4l2loopback (virtual Webcam) 
installed. So if you decide to install the "webcamstudio module" 
(WSVideoDevice) fork, first uninstall v4l2loopback (Dummy device) module first.
Thanks.
karl.

It worked!

Basically what I did was 

1. uninstalled v4l2loopback (just removed v4l2loopback.ko)
2. download the kernel module(webcamstudio-module-112.tar.bz2)
3. compiled, and installed it.
4. after modprobe, there needed not to re-compile the webcamstudio itself. It 
seemed to me that the WebCamstudio detected the loaded module on launch that it 
determines how the interface should look.

From what I saw, two devices are seemingly worked differently at least in 
respect that v4l2loopback (dummy video device) didn't let the flash player 
detect the pseudo-camera but WSVideoDevice did.

Anyway it helped, thank you karl.
