Extracting ID3 Tags out of an Audio stream

Hello all

Is there a way to extract the Artist and Album information out of an internet audiostream?

What have you tried?

searched for ID3 Extractor :slight_smile:

perhaps Im not using the right search term.
I would like to have a node where I put in a URL an get the "Artist", "Album" and so on tags, that are in this stream.

you guess it, Im a complete noob :wink:

Where do you get the 'internet audiostream' from?
Do you know if the 'internet audiostream' actually contains the information?
Do you have a flow that is playing the stream?

  • if so please export the flow and attach it to a reply.

Its from a website and i have no node yet.
Im looking for a way into this.

And when I play the stream in VLC it shows the information that I want.
Stream adress is http://cc6.beheerstream.com:8151/stream

If you install ffmpeg on your system, then it will usually comes with ffprobe. It can be used to get data about various media sources.

run the following command:
ffprobe -loglevel quiet -print_format json -show_format -show_streams http://cc6.beheerstream.com:8151/stream

You could run the command in the exec node and handle the json output and extract whatever data is pertinent.

thank you.
I'll try my best

installed ffmpeg but got error:

"{"code":127,"message":"Command failed: ffprobe -loglevel quiet -print_format json -show_format -show_streams http://cc6.beheerstream.com:8151/stream\n/bin/bash: ffprobe: command not found\n"}"

Node Red runs in a Docker container on a Linux Mint installation
and as I said in the first post - I'm a noob :wink:

The key is in "container", ie. it is isolated from the rest of the system. If you want to keep running in docker, you will need to create a custom docker container, include ffmpeg and build a new image.

Or just run node-red natively then you can access the installed ffmpeg binary from node-red directly.
