How to get a list of Playlists from a Channel ID

[BourgeoisDirk]

I'm trying to download by playlist from a channel, but can't seem to find anything that will get me a list of playlists from given Channel ID.
Is there someway i can get the playlists from a given channel ?

No, there is no way

Then may i add it as a feature request ?

I take it then that a search on channel id would not work ?
var playlistSearch = await Core.Client.Search.GetPlaylistsAsync(ChannelId, Core.ProcessCancellationToken.Token); var playlists = playlistSearch.Cast<YoutubeExplode.Playlists.Playlist>().ToArray();

I guess it could be done backwards for the time being, until there is a Channel.Playlists.GetAsync() ?

public async Task LoadAsync(YoutubeExplode.Channels.Channel channel)
{
var videos = await Core.Client.Channels.GetUploadsAsync(channel.Id, Core.ProcessCancellationToken.Token);
var playlistIds = videos.Select(x => x.PlaylistId).Distinct().Select(x => x.Value).ToList();

var playlists = new Dictionary<string, YoutubeExplode.Playlists.Playlist>();
foreach (var playlistId in playlistIds)
    playlists.Add(playlistId, await Core.Client.Playlists.GetAsync(playlistId, Core.ProcessCancellationToken.Token));

}

I don't want to extend the scope of the project any more. Your approach will be quite slow for large channels and I don't know of anything similar to the special "channel uploads" playlist for playlists.

Hey, i have a problem with Building a Channel Hierarchy from the Videos from a given Channel.

var videos = await Core.Client.Channels.GetUploadsAsync(channel.Id, Core.ProcessCancellationToken.Token);
var playlistIds = videos.Select(x => x.PlaylistId).Distinct().Select(x => x.Value).ToList();

It appears that for some reason, after getting the channel by Handle, and then getting the list of Videos via Channels.GetUploadsAsync(channelId), that all of the video's have the same PlaylistId ❌
Is there any way to build a Hierarchy from a Channel object ? Does not matter if it is slow, i just need to build a list of the PlaylistID's that belong to given Channel.

Kind regards

I don't think it's possible what you're trying to do

[BourgeoisDirk]

Well then, down to a lower level it is ^^

Requirements:

• API Key via Google Console: https://support.google.com/googleapi/answer/6158862?hl=en
• NuGet Package: Google.Apis
• NuGet Package: Google.Apis.YouTube.v3

Code to fetch list of PlaylistIDs from a ChannelID:
using Google.Apis.Services;
using Google.Apis.YouTube.v3;

    private async Task<List<string>> GetPlaylistsAsync(string channelId)
    {
        var youtubeService = new YouTubeService(new BaseClientService.Initializer() { ApiKey = "enter api key here" });

        var playlistListRequest = youtubeService.Playlists.List("snippet");
        playlistListRequest.ChannelId = channelId;

        var playlistListResponse = await playlistListRequest.ExecuteAsync();
        var playlists = playlistListResponse.Items.Select(x => x.Id).ToList();

        return playlists ;
    }

Or, basically just make an HttpRequest and parse the response, you can try this out in a browser:
https://www.googleapis.com/youtube/v3/playlists?key=APIKEY&channelId=CHANNELID&part=snippet

After this you can just get the data from each PlaylistID using YoutubeExplode:
var playlist = await YoutubeExplode.YoutubeClient.Playlists.GetAsync(playlistId, ProcessCancellationToken)
var videos = await YoutubeExplode.YoutubeClient.Playlists.GetVideosAsync(playlist.Id, ProcessCancellationToken)

Keep up the good work !
Kind regards

Great to find this discussion - the same question came up downstream!
I guess this is an interesting feature for channels that host playlists created from videos of other channels - those videos wouldn't pop up in the channel's Uploads playlist.

If all you need is a script you can paste into your browser console to get the playlists from a channel's /playlists page, check this out.
