Video-Docker

Some custom scripts for live video interaction with docker

On the (docker) client

• reading video from real and fake webcams
• accessing webcams on the host
• accessing keyboard events on the host
• displaying a window on the host

On the Host

• listening to an incoming video feed
• simulating an incoming video feed
• sending the incoming video feed to a fake webcam on the client

Setup

For using the virtual camera:

• apt-get install v4l2loopback-dkms
• apt-get install v4l2 so you can use v4l2-ctl for troubleshooting
• make sure to LD_PRELOAD or compile OpenCV with v4l2convert.so so it can read video4linux format. For Ubuntu 16.04 it should live at: /usr/lib/x86_64-linux-gnu/libv4l/v4l2convert.so

For autostart / standalone / gallery mode

• Make sure to add v4l2loopback to /etc/modules so it's always loaded.
• make the scripts executable (by soft-linking them in your users ~/bin folder
• Check the Desktop folder for links to drag into Ubuntu's .config/autostart folder

Other things to consider:

• Enable autologin for your user
• Change the energy settings so your screensaver never turns on

For using docker:

• install docker (plus nvidia-docker)
• install deeplearning docker image of your choice (including opencv)
• extend the docker file by adding v4l2 support
