support youtube playlists

Good request, just needed an extra if to check for playlists. The only odd thing is that playlists need an extra ampersand on the end to take options, i.e. /embed/playlist?list=%id%&?width=640, as opposed to single videos which just do /embed/%id%?width=640

Attached is a patch that adds the support. I didn't do any heavy testing though, only your supplied playlist.

It's just occurred to me that that patch does nothing for thumbnails on playlists. I'll work on that shortly. I guess I'll just grab the thumb of the first video, or something.

I'm really striking out today. Patch in #1 includes a left-over dpm statement. Apologies! Attached is one that removes it.

https://developers.google.com/youtube/2.0/reference#Playlist_feed

might be some data here or in the various docs for the youtube api about how to retrieve that info.

So it basically look like the format is something like this:

A playlist has a url like this:
http://www.youtube.com/playlist?list=PLE5959DFE442479A7

The playlist's id is then the list id minus PL so : E5959DFE442479A7

The playlists info is stored (as xml) at : https://gdata.youtube.com/feeds/api/playlists/E5959DFE442479A7?v=2

and in the xml we have:

<media:group>
<media:content url="http://www.youtube.com/p/E5959DFE442479A7" type="application/x-shockwave-flash" yt:format="5"/>
<media:description type="plain"/>
<media:thumbnail url="http://i.ytimg.com/vi/lb7vHYrTzDo/default.jpg" height="90" width="120" yt:name="default"/>
<media:thumbnail url="http://i.ytimg.com/vi/lb7vHYrTzDo/hqdefault.jpg" height="360" width="480" yt:name="hqdefault"/>
<media:title type="plain">Motorcycle Road Reviews</media:title>
<yt:duration seconds="2875"/>
</media:group>

which tells us that we have 2 thumbnails - the bigger of which is http://i.ytimg.com/vi/lb7vHYrTzDo/hqdefault.jpg

So ... should be a similar processor to how we get the regular thumbnail, just some additional api work in the thumbnail section.

Sidenote - this is also a valid link to the aforementioned playlist, which the current patch doesn't deal with:

https://www.youtube.com/view_play_list?p=E5959DFE442479A7

Alright guys, I think I've covered all the bases. view_play_list links now work (Oddly enough, the ID in them is different. It lacks the 'PL' suffix that playlists have) and playlists are generating thumbnails now. If there's any other cases you can think of that this patch doesn't handle, let me know.

Finally committed this, thanks all.

Now the drupal 8 version doesn't support youtube playlists.

i made a quick and dirty workaround in the two functions below:

video_embed_field/src/Plugin/video_embed_field/Provider/YouTube.php

  public function renderEmbedCode($width, $height, $autoplay) {
    $videoId = $this->getVideoId();
    if (strpos($videoId, 'list') !== false) {
      return [
        '#type' => 'video_embed_iframe',
        '#provider' => 'youtube',
        '#url' => sprintf('https://www.youtube.com/embed/%s', $this->getVideoId()),
        '#attributes' => [
          'width' => $width,
          'height' => $height,
          'frameborder' => '0',
          'allowfullscreen' => 'allowfullscreen',
        ],
      ];
    }
    else {
      return [
        '#type' => 'video_embed_iframe',
        '#provider' => 'youtube',
        '#url' => sprintf('https://www.youtube.com/embed/%s', $this->getVideoId()),
        '#query' => [
          'autoplay' => $autoplay,
          'start' => $this->getTimeIndex(),
          'rel' => '0',
        ],
        '#attributes' => [
          'width' => $width,
          'height' => $height,
          'frameborder' => '0',
          'allowfullscreen' => 'allowfullscreen',
        ],
      ];
    }
  }

  public static function getIdFromInput($input) {
    $playlist = '';
    if (strpos($input, 'list') !== false) {
      // Get playlist id.
      $copy = $input;
      preg_match('([\w\-]{12,})', $copy, $playlist_id);
      $playlist = '?list=' . array_shift($playlist_id);
    }

    preg_match('/^https?:\/\/(www\.)?(youtube\.com\/watch\?.*v=|youtu\.be\/)(?<id>[0-9A-Za-z_-]*)/', $input, $matches);
    return isset($matches['id']) ? $matches['id'] . $playlist : FALSE;
  }

Note: Again, this is a quick and dirty solution, i'm sure the module contributers can integrate a better code solution in the module.

I hope this feature will be added soon.

Thanks for the feature request and reference implementation. I've opened #2688449: Support playlists in YouTube provider to deal with this. If you would like to create a patch, I can provide feedback on the code.

Playlists added to 8.x, see above issue.

Oh that's great thank you. I have tested it but it is not working.

• I checked the checkbox YouTube AND YouTube Playlist in the Video Embed field settings.
• I edited and saved my node.

I also clear all caches but the paylist will not show up, only the first video of the playlist.

The embedded playlists look a lot like normal videos, but they have a tab that slide in from the right. Do you want to log any further support questions in the issue above?

I know this, because with my temporary and dirty code the playlist has worked. But now i see only the first video without a playlist tab, like before my first comment.

Ok i found the reason:

The URL should look like this:
https://www.youtube.com/watch?v=lYFSqKXAfHM&list=PLhIv90n3FQfZPYQ-zJM5DbLl7msn-g8Em

But i insert this kind of URL:
https://www.youtube.com/watch?list=PLhIv90n3FQfZPYQ-zJM5DbLl7msn-g8Em&v=lYFSqKXAfHM

It's the same playlist and on youtube works both. But only the structure of the first URL works with the module. Maybe you can implement this other structure or you can document this somewhere. In any case thank you again.

Ah, interesting. I'll implement both order of parameters.

Implemented in #2690649: Support a wider variety of YouTube playlist inputs..
