Octoprint on debian

Goal

Instead of running octoprint on a raspberry pi, I run it on an old laptop that is lying around here. Below is the code to get video to work.

Setup webcam

Installation of mjpeg streamer

ssh to the device with octoprint installed.

sudo apt install git
sudo apt-get install cmake
sudo apt-get install gcc g++
sudo apt-get install libjpeg62-turbo-dev
sudo apt autoremove
git clone https://github.com/jacksonliam/mjpg-streamer.git
cd mjpg-streamer/
cd mjpg-streamer-experimental
make
sudo make install
sudo chmod 777 /dev/video0 (or whatever your device name is)

command to startup mjpeg streamer with webcam and make it accessible over http port 8080:

mjpg_streamer -i "input_uvc.so -d /dev/video0 -n" -o "output_http.so -p 8080 -w /usr/local/www"

installation of ffmpeg

easy: sudo apt install ffmpeg

To find the path of ffmpeg execute the command whereis ffmpeg, you’ll need it later in the octoprint settings.

setup in octoprint

Enter the following settings:

• Stream url: http://192.168.0.210:8080/?action=stream
• Snapshot url: http://192.168.0.210:8080/?action=snapshot
• Path to FFMPEG: /usr/bin/ffmpeg (or whatever whereis ffmpeg returned)

Press the test button for each of them to see if it works.
