Video extraction does not work with yt-dlp

tumblr-backup 1.0.5 via pip
tumblr-backup --save-video --save-audio acesentialsketches

Using the --save-video flag does not work with yt-dlp. Instead every post with a video will always fail with a simple failure message.

Unable to download video in post #152679750480

Looking into the code the cause seems to be that the result returned from yt-dlp does not contain a key called entries.

result = ydl.extract_info(youtube_url, download=False)
media_filename = youtube_dl.utils.sanitize_filename(filetmpl % result['entries'][0], restricted=True)

I'm not sure if this is a change between youtube-dl and yt-dlp but with yt-dlp 2024.11.18 there is no "entries" key in the result object. Instead the template keys seem to be embedded directly at the root level. This results in an exception and means no videos will be saved.

A simple fix preserving compatibility with any ancient version of youtube-dl would be:

result = ydl.extract_info(youtube_url, download=False)
if 'entries' in result:
    result = result['entries'][0]
media_filename = youtube_dl.utils.sanitize_filename(filetmpl % result, restricted=True)
