Manages a virtual camera camera device that transform the image captured from another camera (generally physical).
Uses opencv to read and transform images from the camera and the v4l2-loopback Linux kernel module to control the virtual camera.
To install v4l2-loopback (in Debian and Ubuntu)
./install-v4l2.sh
To setup a virtual camera (unsing v4l2loopback module)
./setup-cameras.sh
or ten?
./setup-cameras.sh 10
To start a vcamera (assuming /dev/video0 is your capture device and /dev/video1 your virtual camera)
sudo ./vcamera.py -i /dev/video0 -o /dev/video1 -f flip sunset
To display the running vcamera at the browser start the webserver
./camera-select-app.py
or
./show-camera-app.py
and open the url http://localhost:8080/.
The original image can be transformed by overriding the method transform
of class VCamera in a new subclass.
For fast development vcamera can be runned and displayed using opencv (-p)
sudo ./vcamera.py -i /dev/video0 -o /dev/video1 -f flip sunset -p
Some example filters to use at transform can be found at filters.py.
