playlistgrabber

Pull full playlists from YouTube and automatically convert mp4 to mp3

$ git clone https://github.com/guidoesser/playlistgrabber.git 
$ sudo apt install ffmpeg
$ cd playlistgrabber
$ mkdir mp3
$ chmod +x ./source/mp4tomp3.sh
$ python3 -m venv env 
$ . env/bin/activate
$ pip install -r requirements.txt
$ python ./source/get_playlist.py

At the moment you will get the following error message:
"pytube.exceptions.RegexMatchError: regex pattern (\W['"]?t['"]?: ?'"['"]) had zero matches"

You have to change pytube in your environment:

$ nano ./playlistgrabber/env/lib/python3.6/site-packages/pytube/extract.py

Change

    if age_restricted:
        sts = regex_search(r'"sts"\s*:\s*(\d+)', embed_html, group=1)

        # Python 2.7+.
        params = OrderedDict([
            ('video_id', video_id),
            ('eurl', eurl(video_id)),
            ('sts', sts),
        ])
    else:
        # I'm not entirely sure what ``t`` represents. Looks to represent a
        # boolean.
        t = regex_search(
