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sorry but WS 0.5x is no longer maintained.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:

https://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.

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.

Thanks,
karl
