I'm new with node-red. I'm following the instructions on https://youtu.be/ihZWrJmbGFY I installed the libav-tools as instructed, I can open the program on the Raspberry Pi with avconv. I created the folder and edited the settings.js file. When I open node-red, I don't see the nodes in the nodes …

Sorry i don’t have time to watch a 40minute video to find out what you did. But assuming you did it in a terminal window you should be able to use the history command to get a list of the commands you used. How are you starting Node-RED? What version of Node-RED and nodejs are you using?

Hi UKMoose Node-Red version: v0.20.1 Version of nodejs: v10.15.3 Install of libav-tools: sudo apt-get install libav-tools Avconv --> works Opening node-red via ipaddres:1880/#flow Is that the information you need? Thank you for your reply. Yvonne

so where have you actually installed any Node-RED nodes?

On the Raspberry Pi in the home directory there is a directory node_modules

and how did you install these nodes?

sudo apt-get install libav-tools

That isn’t a Node-RED node which is why none will be showing up. To install node-RED nodes you would normally be in you .node-red directory and install nodes with a command like npm install node-red-contrib-something You can see a near complete list of installable nodes at flows.nodered.org

Hi @lodv I have quickly scanned through the video, and it looks like he is using the built-in Exec node to run the avconv command-line tool. So there are no extra nodes to look for in your palette - use the exec node to run the command
