I use the UV4L driver (RasPiCam) from here with the WebRTC extension to get a continuous live view, streaming out from this HTTP server (RaspberryPi).
I would like to examine the sourcecode running on the server. Or is it closed source?
According to this webpage, the driver is closed-source.
There is now an open-source driver that has been integrated into the kernel as of December 2013.
To use it, simply update your Raspberry Pi and run:
sudo modprobe bcm2835-v4l2
To have the device node /dev/video0 created. You can now use v4l2 compatible applications instead of uv4l, of which, there is greater availability.
