Convert web pages to mp3 files

Disclaimer: this has been done for my own use, feel free to use it and submit changes, but I probably won't spend a lot of time maintaining it.

This is a tiny web extension which does two things:

• convert your shazam tags into mp3 files;
• download any Youtube page as an mp3 file.

Requirements

First, this extension requires some steps before working properly.

It requires that you install the python application locally, and that you install the youtube-dl package.

You will also need to add the native messaging app to the known ones.

On any linux machine, all of this can be accomplished with the following commands:

apt install youtube-dl python3
mkdir ~/.apps && mkdir ~/.mozilla/native-messaging-hosts/
wget https://raw.githubusercontent.com/almet/web2mp3/master/web2mp3.py -O ~/.apps/web2mp3.py
wget https://raw.githubusercontent.com/almet/web2mp3/master/web2mp3.json -O ~/.mozilla/native-messaging-hosts/web2mp3.json
chmod +x ~/.apps/web2mp3.py
chmod +x ~/.mozilla/native-messaging-hosts/web2mp3.json
sed -i "s:/home/alexis/.apps:`echo ~/.apps`:g" ~/.mozilla/native-messaging-hosts/web2mp3.json

Then, install the extension.

Of course, you can install in a different location, just think about updating your paths!

Then, head to any youtube page, or to your shazams and click on the icon next to the URL. Your shazam tags will be automatically downloaded and available in ~/web2mp3.

Enjoy ;)

Using yt-dlp

Youtube-dl has been forked to yt-dlp, and you can use this instead. The web2mp3.py script is looking for a youtube-dl, so you might need to create a symlink to make this work.

For instance, you could install yt-dlp with pipx:

# Install using pipx
pipx install yt-dlp

# Create a symlink in /usr/local/bin
sudo ln -s `which yt-dlp` /usr/local/bin/youtube-dl
