Virtual Camera

Use the Camera Board on the Rpi as a (virtual) camera plugged into another PC

Here we go:

  1. install UV4L and the MJPEGStream driver on your PC (download the packages for Ubuntu, or the generic archive), then upgrade UV4L on the Rpi to the latest version;
  2. make sure the UV4L Streaming ServerĀ is running on the Rpi;
  3. make a virtual Video4Linux2 device on your PC from the above stream with the following command:
mypc ~ $ uv4l --driver mjpegstream --auto-video_nr --uri http://raspberrypi:8080/stream/video.jpeg

Now you have a device registered as /dev/video0 (or higher) on your PC that you can use as you prefer, for example:

mypc ~ $ LD_PRELOAD=/usr/lib/uv4l/uv4lext/x86_64/ jitsi


mypc ~ $ vlc v4l2:///dev/video0

The LD_PRELOAD environment variable has to be set for some applications. If you are in doubt, always specify it. Jitsi is a video-conferencing application which can be downloaded at
