Get a camera running on raspberry pi:
$ mkdir /tmp/stream
$ raspistill --nopreview -w 640 -h 480 -q 5 -o /tmp/stream/pic.jpg -tl 100 -t 9999999 -th 0:0:0 &
We are using timelapse mode (-tl) where a shot is taken every 100 ms. -q is for jpeg quality <0-100>. -t is timeout, also in ms. -th is dimensions:quality of thumbnail to be inserted into output jpg.
Optional: Add -vf and -hf to flip the image vertically and horizontally.
Turn captured images into a web stream:
$ LD_LIBRARY_PATH=/usr/local/lib mjpg_streamer -i "input_file.so -f /tmp/stream -n pic.jpg" -o "output_http.so -w /usr/local/www"
This automatically opens HTTP tcp port 8080.
raspberry pi:
$ autossh -M 65500 -o "ExitOnForwardFailure yes" -o "ServerAliveInterval 60" -o "ServerAliveCountMax 3" -o "StrictHostKeyChecking=no" -R <webserver.address>:<proxy_port>:127.0.0.1:8080 <username@webserver.address>
