YouTube playlist length - youtube

I would like to know if there's a way to get the number of total videos in a playlist.
I'm building a Python script that need to get the number of videos to do a for loop. Or, if getting this information isn't possible, can you give me a way to do it without a for loop?

You can use the following request
https://www.googleapis.com/youtube/v3/playlistItems?part=id&maxResults=0&playlistId={PLAYLIST_ID}&key={YOUR_API_KEY}
Look for 'totalResults' in the response, which will give you a total number of videos in the playlist

Here's another way, using Python and not constructing a URL string from scratch:
With the Python API for listing out playlistItems (assuming you're looking for publicly available playlists only), you build a resource object to interact with the API, and then query the result for your playlistId of choice:
client = build('youtube', 'v3', developerKey=<your_api_key>)
res = client.playlistItems().list(playlistId=<your_playlist_id>, part='snippet').execute()
length_of_playlist = res['pageInfo']['totalResults']

Tracking down URLs of deleted videos in a youtube playlist

I've recently made a Python program using the Youtube api v3 where, given a playlist id, it fetches certain information from every video in the playlist. However, through both the output of this code and this post on Google, it's pretty clear that information on videos that were either privated or deleted is not available through the Youtube api.
Is there an alternative program or resource that I can use to extract information from these unavailable videos, in particular their video ids?
The only solution I can think of now is to access the HTML of the display Youtube and search through it for certain strings (like "[deleted video]") and to then extract the id corresponding to that string. But, I've never dealt with HTML and, if I understand HTML correctly, I'd have to load a new page for every 50 videos in the playlist, which for playlists with thousands of videos, becomes rather inefficient and laborious.
I was hoping to use something like PyTube, but that couldn't handle unavailable videos either.
Edit
Here is the code that extracts the video ids:
from googleapiclient.discovery import build
api_key = "AI~~~" #get from yt (private key)
yt = build("youtube", "v3", developerKey = api_key)
plst_id = "PLorw3mfu-J0ipF4Ss0XgR8IxcwP-JzNKC" #unique yt playlist id
plst_req = yt.playlistItems().list( #request for info from yt api
part = "contentDetails",
playlistId = plst_id,
maxResults = 50
)
plst = plst_req.execute()
vid_ids = [] #available video ids taken from current playlist
for vid in plst['items']:
vid_ids.append(vid['contentDetails']['videoId'])
print(vid_ids)
print(plst['pageInfo']['totalResults'])
The first line printed contains the video ids of every available video in the playlist. The second line printed gives the number of videos in the playlist, including available and unavailable ones.
The playlist used in the code above is given here. It contains 10 total videos, of which one of them is unavailable.
In this case, the output is (with a valid api key)
['bv_cEeDlop0', 'mRKTOZmX2cE', '5ACvKdx1nns', 'wSNhP8b_Avo', 's56cHgokPlE', 'E4IHMWnQiMw', 'sCDkPShADSc', 'EVwgeUVVDYU', 'Z8Mqw0b9ADs']
10
Youtube still treats unavailable videos as an element of the playlist, but does not give out it's video id. In this particular instance, the video id of the unavailable video is "t83zUmjr05I", which is not hard to find manually: copy the link address of the deleted video and extract the part after the "v=".
But, on a larger scale manual extraction becomes tedious.
Here's a permanent fix to that!
You can try tube_dl.
pip install tube_dl
It uses modular approach and is up to date
More about this can be found at : https://github.com/shekharchander/tube_dl/
Maybe, the playlist module can help you with that. It uses regex to grab all video IDs not JSON. Please let me know if the problem is fixed or not, I will update module accordingly.
Edit
Here's the working code
from tube_dl import Playlist
p = Playlist('https://youtube.com/playlist?list=PLorw3mfu-J0ipF4Ss0XgR8IxcwP-JzNKC').videos
print(p)

Get Video Views for Group of YouTube Videos

I can get a list of videos from a channel I'm querying. I have most of the information I need in an existing api call, but I'd really like to also get the number of times each video has been viewed.
My current query gives me 50 results:
https://www.googleapis.com/youtube/v3/search?part=id,snippet&key=' . $key . '&channelId=' . $channelId . '&order=date&maxResults=50&publishedBefore=' . $publishedBefore
I read I can get viewCounts through the API by providing a video id. But that's one at a time. I'm hoping I can ammend my query above to also output the viewCounts to make 1 query instead of 51 queries.
I have a part attribute that I can set to "a comma-separated list of one or more search resource properties that the API response will include." The examples I've seen have "id,snippet", but can I specify a value that will provide how many times the video has been viewed? I can't find a list of search resource properties.
Also, is there a way to view a channel's "hottest" or "trendiest" videos that they currently have?
You can make one single request which get statistics from youtube API. You need to call API like this
https://content.googleapis.com/youtube/v3/videos?id=Ks-_Mh1QhMc,Cc0KYU2j0TM4,CeIho2S0ZahI&part=statistics&key={APIKEY}
In this request I am getting data from 3 videoId, you can get upto 50 videos at a time.

YouTube API - get tags for all videos with playlist query

I'm querying YouTube channels to retrieve playlist metadata like this:
https://www.googleapis.com/youtube/v3/playlistItems?part=snippet%2CcontentDetails&maxResults=5&playlistId={PLAYLIST_ID}&key={API_KEY}
This query returns an array of all of the videos on the channel. Each object in that array includes various fields that provide metadata on each video, but none of these fields include the tags associated with the video. I can get that data using a query like this:
https://www.googleapis.com/youtube/v3/videos?key={API_KEY}&fields=items(snippet(title,description,tags))&part=snippet&id={VIDEO_ID}
The problem with that is that now I need to issue a separate query for every single video that comes back in the first query.
So, my question is, is there a way that I can get these tags included as part of the initial JSON object from the first query? Can I add any parameters that will request this data be included with that response?
Thanks for any help!
Short answer: No.
The PlaylistItems: list documentation does not show a way to get video tags from the playlistItems endpoint. The only parts available are id, snippet, status and contentDetails and neither of those contain tags.
However!
You do not have to make a request for each video in the playlist! The documentation states:
The id parameter specifies a comma-separated list of the YouTube video ID(s) for the resource(s) that are being retrieved. In a video resource, the id property specifies the video's ID. (string)
That means you can supply multiple, comma-separated video ids to the videos endpoint.
Example:
GET https://www.googleapis.com/youtube/v3/videos?part=snippet&id=kOkQ4T5WO9E,a59gmGkq_pw,Io0fBr1XBUA&key={YOUR_API_KEY}
So in total, it will cost you two requests to get the tags of all videos in a playlist.*
*In practice, you might have to make more than two requests. If I remember correctly, YouTube limits the returned items to 50 per request. Thus, if the playlist contains more than 50 videos, you will have to make another request with the pageToken parameter set.

Can't get endAt on videos when calling

I'm using GET https://www.googleapis.com/youtube/v3/playlistItems?part=contentDetails%2Csnippet&maxResults=50&playlistId=PLFs4vir_WsTwwb2zqmtE2WTEFdc7AQHnc&key={YOUR_API_KEY}
This returns all data, but only videoId in each video contentDetails. Maybe I'm missing something here?
YouTube has removed the features that set start and end times to playlist items: here's a product forum post that details this (and indicates an official response from Google account reps):
https://productforums.google.com/forum/#!topic/youtube/Gipu_cCDScI
Since playlists can no longer set start/end times on its items, the API no longer delivers them.
Not an answer, but a workaround. You can retrieve a playlist and use videos list with up to 50 videoIds in the URL to retrieve each video duration.

youtube v3 api : get all live streaming playlist ids of a channel

I have two "Live streaming/live broadcast saved playlists" in following youtube channel --> https://www.youtube.com/user/swaminarayanlive.
I am trying to retrieve all the "live streaming / live broadcast playlists" of a channel using new youtube v3 api by using the below link-->
https://www.googleapis.com/youtube/v3/playlists?part=snippet&channelId=UCBkNpeyvBO2TdPGVC_PsPUA&key={YOUR_API_KEY}
here i can get the info of playlists which are not live streams or live broadcast. and not able to get the same for the live one.
Please help me how can i get that for live one using youtube v3 api
I was researching another issue with the API when finding this, and when I saw that this was never resolved, I decided to look into it. It turns out that this is related to that other issue.
The YouTube API v3 lacks support for saved playlists. The channel swaminarayanlive did not create the playlists, only saved them from the channel BhujMandir.
The workaround in your case would be to retrieve the playlists of BhujMandir and extract the response snippets with "title" parameters containing the word "Live".
You would need to go through the pages and search each one for this, since there is a limit to how many results an API response can show at once. Currently it's 50.
So, you would use the following to get the first page of playlistItems:
GET https://www.googleapis.com/youtube/v3/playlists?part=snippet&channelId=UCVItNtUctAknegvmYcMhUQg&maxResults=50&key={YOUR_API_KEY}
This will return an API response containing the properties "kind" (which will have the value "youtube#playlistListResponse") and "etag". If there are more than 50 results, there will also be a "nextPageToken" property. (On a page that is not the first, there would also be a "prevPageToken" property.)
After these properties, there are two blocks. One called "pageInfo", containing info about how many results (playlists) there are and how many are shown per page, and one block called "items", containing the resulting playlistItems.
You would look through the items block for any playlistItem with a title property (which is a string) containing the substring "Live" and get the id properties of those. You would then look on the next page by using the nextPageToken's value in a new HTTP request, like so:
GET https://www.googleapis.com/youtube/v3/playlists?part=snippet&channelId=UCVItNtUctAknegvmYcMhUQg&maxResults=50&pageToken=[nextPageToken_value_here]&key={YOUR_API_KEY}
As of now, the two playlists you're looking for are on the pages with tokens CJYBEAA and CMgBEAA.
I think that where is the {YOUR_API_KEY} you should change this code and insert the name of your application program interface
