[Question] How to get all the videos link in a playlist

[niltsh]

If it is a duplication, please let me know.

I am now trying to integrate this great SW into my multimedia player.
I could now successfully get the URL and title of the video, by using -g and -e.

Now I am trying to add the playlist support into the player.
And I want to confirm how to achieve following

1. How to understand whether a link is a playlist or single video?
2. How to list all the links of the videos contained in the playlist? Don't have to decode all the links, but need the list quickly.

Currently, just using -g could list all the decoded URLs, but it takes a long time to finish, looks like youtube-dl is extracting each video's link one by one.

I wonder if there is any quick way to get all the links, even not to extract the real URL but the encoded ones.

Thank you.

BRs,

1. Playlist has _type field that equals playlist in dictionary.
2. Use --flat-playlist --dump-single-json or --flat-playlist --dump-json. There is a url field in each video's dictionary. Note that it may not be a real URL but a youtube-dl shortcut (e.g. nrk:203298) or smuggled URL.

Hi Sergey

_type

​What do you mean the "_type"? How I could find this entry, in what
dictionary?

For example:

$ youtube-dl 'https://www.youtube.com/playlist?list=PLwiyx1dc3P2JR9N8gQaQN_BCvlSlap7re' --flat-playlist --dump-single-json  | jq .
{
  "extractor": "youtube:playlist",
  "entries": [
    {
      "id": "bV9L5Ht9LgY",
      "url": "bV9L5Ht9LgY",
      "_type": "url",
      "ie_key": "Youtube"
    },
    {
      "id": "FXxLjLQi3Fg",
      "url": "FXxLjLQi3Fg",
      "_type": "url",
      "ie_key": "Youtube"
    },
    {
      "id": "tU3Bgo5qJZE",
      "url": "tU3Bgo5qJZE",
      "_type": "url",
      "ie_key": "Youtube"
    }
  ],
  "_type": "playlist",
  "webpage_url_basename": "playlist",
  "webpage_url": "https://www.youtube.com/playlist?list=PLwiyx1dc3P2JR9N8gQaQN_BCvlSlap7re",
  "id": "PLwiyx1dc3P2JR9N8gQaQN_BCvlSlap7re",
  "extractor_key": "YoutubePlaylist",
  "title": "ytdl test PL"
}

It returns a single json object with the playlist info. The entries field contains the urls of the videos that can be used with youtube-dl to get the full info (if you remove --flat-playlist you get the info, but the final urls may have expired when you try to play them).

You may want to have a look at how mpv calls youtube-dl.
