Extracting ID3 Tags out of an Audio stream

General
1

Hello all

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

2

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

output:

}

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

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.
