Minimal example of how to create a working Anki deck with a media file embedded.

genanki-media-test.py

import genanki

my_model = genanki.Model(
  1380120064,
  'Example',
  fields=[
    {'name': 'Object'},
    {'name': 'Image'},
  ],
  templates=[
    {
      'name': 'Card 1',
      'qfmt': '{{Object}}',
      'afmt': '{{FrontSide}}<hr id="answer">{{Image}}',
    },
  ])

my_note = genanki.Note(
  model=my_model,
  fields=['JPEG File', '<img src="format.jpg" />'])

my_deck = genanki.Deck(
  2059400191,
  'Example')

my_deck.add_note(my_note)

my_package = genanki.Package(my_deck)
my_package.media_files = ['format.jpg']

my_package.write_to_file('output.apkg')

Thanks for this, I was absolutely lost.

@mgnisia, @lowttl, @danpaldev, @chrisalbon — thanks so much for letting me know this was helpful! 🤗

@danpaldev: I am no expert, but as far as I know, that is not possible, the only thing that is possible is for you to batch generate the cards, such that you generate cards from a template that has the word on the front, and an MP3 of that word on the back. You would have to generate those cards, because AFAIK, Anki doesn't have any meta-programming features.

Thank you so much for the example, @jlumbroso ! However, I am getting "format.jpg" doesn't exist. Where did you place that file ? In the root of your drive ?
