Review comment (refactor):
I would combine these functions since `_extract_entries` is only used once.
```suggestion
    def _real_extract(self, url):
        video_id = self._match_id(url)
        query = {self._INFO_QUERY_KEY: video_id}

        data = traverse_obj(
            self._get_api(self._INFO_API, video_id, query=query), self._DATA_PATH)

        metainfo = traverse_obj(data, self._META_PATH)
        entries = [{
            **metainfo,
            **self._extract_video(id)
        } for id in set(traverse_obj(data, self._ID_PATH))]

        return self.playlist_result(entries, **metainfo, id=video_id)
```
