How to add album art, track and artist data to file with YouTube-DL Embedded in Python

[ghost]

How would i use the ytd_opts{} to add track data to the converted mp3 file, specifcally the album art, artist, and album?

Add FFmpegMetadata postprocessor to postprocessors list.

How would I include "artist", "description" etc?

@dyablade looks lke you need a custom PostProcessor for it since FFmpegMetadata only parses the info already generated:

import youtube_dl
from youtube_dl.postprocessor.ffmpeg import FFmpegMetadataPP


class MyLogger(object):
    def debug(self, msg):
        pass

    def warning(self, msg):
        pass

    def error(self, msg):
        print(msg)


def console_hook(d):
    if d['status'] == 'finished':
        print('Done downloading, now converting ...')

    if d['status'] == 'downloading':
        if d.get('eta') is not None:
            print(d['_percent_str'])
        else:
            print('Unknown ETA')


class FFmpegMP3MetadataPP(FFmpegMetadataPP):

    def __init__(self, downloader=None, metadata=None):
        self.metadata = metadata or {}
        super(FFmpegMP3MetadataPP, self).__init__(downloader)

    def run(self, information):
        information = self.purge_metadata(information)
        information.update(self.metadata)
        return super(FFmpegMP3MetadataPP, self).run(information)

    def purge_metadata(self, info):
        info.pop('title', None)
        info.pop('track', None)
        info.pop('upload_date', None)
        info.pop('description', None)
        info.pop('webpage_url', None)
        info.pop('track_number', None)
        info.pop('artist', None)
        info.pop('creator', None)
        info.pop('uploader', None)
        info.pop('uploader_id', None)
        info.pop('genre', None)
        info.pop('album', None)
        info.pop('album_artist', None)
        info.pop('disc_number', None)
        return info


url = 'https://www.youtube.com/watch?v=EL8e2ujXe8g'
metadata = {
    "title": "Stop",
    "artist": "Movie",
}
ydl_opts = {
    'format': 'bestaudio/best',
    'postprocessors': [{
        'key': 'FFmpegExtractAudio',
        'preferredcodec': 'mp3',
        'preferredquality': '192',
    }],
    'outtmpl': 'result.%(format)s',
    'logger': MyLogger(),
    'progress_hooks': [console_hook],
}

with youtube_dl.YoutubeDL(ydl_opts) as ydl:
    ffmpeg_mp3_metadata_pp = FFmpegMP3MetadataPP(ydl, metadata)
    ydl.add_post_processor(ffmpeg_mp3_metadata_pp)
    ydl.download([url])
