Are the URLs like this one valid?

https://www.youtube.com/user/IngridMichaelsonVEVO#p/a/u/1/QdK8U-VIH_o

In that, yes, they go to a You Tube user's channel, but I suspect everything after the # is ignored, so the video ID isn't used. In fact that anchor suffix could be anything at all, and it would be correct not to parse the video ID.

Likewise, I wonder about these URLs with a vi in place of a v. They all either go to a 404-not-found or are redirected to youtube.com's front page. Even if I insert an ID I know works with other URLs - so it's not simply the video has been taken down.

http://youtube.com/?vi=dQw4w9WgXcQ&feature=youtube_gdata_player
http://youtube.com/watch?vi=dQw4w9WgXcQ&feature=youtube_gdata_player
http://youtube.com/vi/dQw4w9WgXcQ?feature=youtube_gdata_player
http://youtube.com/vi/oTJRivZTMLs&feature=channel
http://youtube.com/watch?vi=oTJRivZTMLs&feature=channel

And URLs like this, with a v= parameter and no watch:

http://youtube.com/?v=XXXXXXXXXXX&feature=youtube_gdata_player
http://www.youtube.com/?v=XXXXXXXXXXX
http://www.youtube.com/?feature=player_embedded&v=XXXXXXXXXXX
http://youtube.com/?v=XXXXXXXXXXX&feature=channel
http://youtube.com/?feature=channel&v=XXXXXXXXXXX

I've not made an exhaustive test, but it does seem to find a lot of questionable URLs. It's quite possible these work for someone else, but has anyone evidence these URLs ever did link to a video?

I've tried a couple and it seems some of the weirder looking ones may or do not work, I've left them in my regex for potential matches if I ever find one in the wild and want to quickly get the ID

Thanks for reporting these @wu-lee. I'm going to do some tests over the weekend and leave some comments in the list for any of the links that don't work anymore. It might be the case that YouTube has deprecated these URLs.

I think these URLs with vi components may be for thumbnail images associated with videos. For example, this is one:

https://i.ytimg.com/vi/XXXXXXXXXXX/default.jpg

Are query strings that use & first instead of ? valid?
because its on lines 118 and 119, and python's urllib parsing library did not recognise it and made the query strings part of the path.
eg:

from urllib import parse

components = parse.urlparse("https://youtu.be/oTJRivZTMLs&feature=channel")
print(components.path)

results in an output of

oTJRivZTMLs&feature=channel

while normally

from urllib import parse

components = parse.urlparse("https://youtu.be/dQw4w9WgXcQ?feature=youtube_gdata_player")
print(components.path)

results in just

dQw4w9WgXcQ

So either this is a mistake on the urls listed or a bug with the python urllib library

It's neither a mistake nor a bug. The &feature=channel is indeed part of the path, not a query string parameter. However, YouTube's url shortener service (the youtu.be) will do the job of parsing the path parameter into what youtube.com needs, and so it'll translate and redirect https://youtu.be/oTJRivZTMLs&feature=channel into something like https://www.youtube.com/watch?v=oTJRivZTMLs&feature=channel&feature=youtu.be.

Here's a python regex that matches all of the links in this gist:

^((https?://(?:www\.)?(?:m\.)?youtube\.com))/((?:oembed\?url=https?%3A//(?:www\.)youtube.com/watch\?(?:v%3D)(?P<video_id_1>[\w\-]{10,20})&format=json)|(?:attribution_link\?a=.*watch(?:%3Fv%3D|%3Fv%3D)(?P<video_id_2>[\w\-]{10,20}))(?:%26feature.*))|(https?:)?(\/\/)?((www\.|m\.)?youtube(-nocookie)?\.com\/((watch)?\?(app=desktop&)?(feature=\w*&)?v=|embed\/|v\/|e\/)|youtu\.be\/)(?P<video_id_3>[\w\-]{10,20})

Python 3 implementation:

def get_youtube_video_id_by_url(url):
    regex = r"^((https?://(?:www\.)?(?:m\.)?youtube\.com))/((?:oembed\?url=https?%3A//(?:www\.)youtube.com/watch\?(?:v%3D)(?P<video_id_1>[\w\-]{10,20})&format=json)|(?:attribution_link\?a=.*watch(?:%3Fv%3D|%3Fv%3D)(?P<video_id_2>[\w\-]{10,20}))(?:%26feature.*))|(https?:)?(\/\/)?((www\.|m\.)?youtube(-nocookie)?\.com\/((watch)?\?(app=desktop&)?(feature=\w*&)?v=|embed\/|v\/|e\/)|youtu\.be\/)(?P<video_id_3>[\w\-]{10,20})"
    match = re.match(regex, url, re.IGNORECASE)
    if match:
        return (
            match.group("video_id_1")
            or match.group("video_id_2")
            or match.group("video_id_3")
        )
    else:
        return None

It matches everything in the gist, but can probably be improved upon for performance, so feel free to suggest improvements!
Just test them here first: https://regex101.com/

I've written a regexless version in python using its built-in url parser. Full code here. You will also notice the version that works with playlists. That one works with the following urls

def extract_video_id(url: str) -> Optional[str]:
    """
    This should work for every url listed here:
    https://gist.github.com/rodrigoborgesdeoliveira/987683cfbfcc8d800192da1e73adc486#file-activeyoutubeurlformats-txt
    and more.
    Args:
        url (str): The url to strip the id from
    Returns:
        Optional[str]: The video id with the rest of the url removed
    """
    components = parse.urlparse(url.replace("&", "?", 1) if "?" not in url else url)
    queries = parse.parse_qs(components.query)
    encoded_query_matches = {'u', 'url'}.intersection(set(queries.keys()))
    if 'v' in queries:
        return queries["v"][0]
    elif encoded_query_matches:
        return extract_video_id(parse.unquote(queries[encoded_query_matches.pop()][0]))
    elif components.netloc == "i.ytimg.com":
        return pathlib.Path(components.path).parts[2]
    elif pathlib.Path(components.path).name not in ["playlist"]:
        return pathlib.Path(components.path).name

Hi,

recently links generated using the "Share" button under a video will contain some additional ?si= query parameter:

https://youtu.be/_UuD60EZGkg?si=eP5r-sAojFjjVYCY

Not sure what it is for, probably more tracking?

Oh, interesting. Thanks, @tacerus!

Hi,

recently links generated using the "Share" button under a video will contain some additional ?si= query parameter:

https://youtu.be/_UuD60EZGkg?si=eP5r-sAojFjjVYCY

Not sure what it is for, probably more tracking?

Yea, most probably it's true.
And have you noticed that every time you share a URL, the tracking ID changes, even for the same video on the same device? If it's a tracking parameter, then it can track the sender and receiver of the YouTube URL. In short, Google can know who your close relatives and friends are. This is surely a messed up thing.

For those using javascript/typescript, I have a function and regex working for all combinations above plus youtube shorts:

export function getVideoIdFromYoutubeUrl(url: string) {
  const regex = /(?:youtu\.be\/|youtube\.com(?:\/(?:[^\/\n\s]+\/\S+\/|(?:v|e(?:mbed)?)\/|\S*?[?&]v=|shorts\/)|youtu\.be\/|embed\/|v\/|m\/|watch\?(?:[^=]+=[^&]+&)*?v=))([^"&?\/\s]{11})/gm;
  return regex.exec(url)[1];
}

export function validateYoutubeTestUrls() {
  const youtubeTestUrls: { key: number; value: string }[] = [
    { key: 1, value: "http://www.youtube.com/watch?v=-wtIMTCHWuI" },
    { key: 2, value: "http://youtube.com/watch?v=-wtIMTCHWuI" },

For some reason, youtube blocks access to the site via the 11th one. It brings up the "our systems have detected unusual traffic from your computer network" message but with no captcha

Here is a java version of regex that matches all the urls the list:

(?i)^(?:https?://)?(?:(?:www|m)\.)?youtu(?:\.be|be(?:-nocookie)?\.com)/(?:(?:oembed|attribution_link)\?.+?(?:/|%2F)(?=watch))?(?:(?:watch)?(?:\?|%3F)|(?:vi?|live|e(?:mbed)?)/)?(?:(?:[\w\-]+(?:=|%3D)[^=&#]+(?:&(?:amp;)?|%26))*?vi?(?:=|%3D))?(?<id>[\w\-]+)(?:(?:(?:\?|%3F)|(?:&(?:amp;)?|%26)|(?:#|%23))[\w\-]+(?:=|%3D)[^=&#]+)*$

String QM = "(?:\\?|%3F)";
String EQ = "(?:=|%3D)";

Thanks @rodrigoborgesdeoliveira!

Here is a JavaScript version - it returns the 13 IDs found in the list you posted

const delParms = ['a', 'app', 'list', 'feature', 'rel', 'si'];

const ids = new Set(
  list.map(url => {
    // Normalize URL
    url = url.replace(/(attribution_link|uploademail|youtube-nocookie)/gi, 'x');
    // Parse URL
    let urlObject = new URL(url);
    // Check for embedded URL and parse it if present
    const embed = urlObject.searchParams.get('url');
    if (embed) urlObject = new URL(embed);
    // Extract 'v' parameter if present
    const v = urlObject.searchParams.get('v');
    if (v) return v;
    // Remove unwanted parameters
    delParms.forEach(parm => urlObject.searchParams.delete(parm));
    // Convert URL to string and replace encoded '='
    url = urlObject.toString().replace(/%3D/gi, '=');
    // Extract ID from URL
    const idMatch = url.match(/[\-_a-z0-9]{10,15}/i);
    const id = idMatch ? idMatch[0] : `No: ${url}`;
    return id;
  })
);
console.log(ids);

Here's a python regex that matches all of the links in this gist:

^((https?://(?:www\.)?(?:m\.)?youtube\.com))/((?:oembed\?url=https?%3A//(?:www\.)youtube.com/watch\?(?:v%3D)(?P<video_id_1>[\w\-]{10,20})&format=json)|(?:attribution_link\?a=.*watch(?:%3Fv%3D|%3Fv%3D)(?P<video_id_2>[\w\-]{10,20}))(?:%26feature.*))|(https?:)?(\/\/)?((www\.|m\.)?youtube(-nocookie)?\.com\/((watch)?\?(app=desktop&)?(feature=\w*&)?v=|embed\/|v\/|e\/)|youtu\.be\/)(?P<video_id_3>[\w\-]{10,20})

Python 3 implementation:

def get_youtube_video_id_by_url(url):
    regex = r"^((https?://(?:www\.)?(?:m\.)?youtube\.com))/((?:oembed\?url=https?%3A//(?:www\.)youtube.com/watch\?(?:v%3D)(?P<video_id_1>[\w\-]{10,20})&format=json)|(?:attribution_link\?a=.*watch(?:%3Fv%3D|%3Fv%3D)(?P<video_id_2>[\w\-]{10,20}))(?:%26feature.*))|(https?:)?(\/\/)?((www\.|m\.)?youtube(-nocookie)?\.com\/((watch)?\?(app=desktop&)?(feature=\w*&)?v=|embed\/|v\/|e\/)|youtu\.be\/)(?P<video_id_3>[\w\-]{10,20})"
    match = re.match(regex, url, re.IGNORECASE)
    if match:
        return (
            match.group("video_id_1")
            or match.group("video_id_2")
            or match.group("video_id_3")
        )
    else:
        return None

It matches everything in the gist, but can probably be improved upon for performance, so feel free to suggest improvements! Just test them here first: https://regex101.com/

Thank you for sharing this snippet. Working great.

Just FYI both these functions do not work for URLs in the following format.

https://www.youtube.com/watch/-wtIMTCHWuI

For those using javascript/typescript, I have a function and regex working for all combinations above plus youtube shorts:

export function getVideoIdFromYoutubeUrl(url: string) {
  const regex = /(?:youtu\.be\/|youtube\.com(?:\/(?:[^\/\n\s]+\/\S+\/|(?:v|e(?:mbed)?)\/|\S*?[?&]v=|shorts\/)|youtu\.be\/|embed\/|v\/|m\/|watch\?(?:[^=]+=[^&]+&)*?v=))([^"&?\/\s]{11})/gm;
  return regex.exec(url)[1];
}

            or match.group("video_id_3")
        )
    else:
        return None

to cover these edge cases, you can use the following regex:

/(?:https?:\/\/)?(?:www\.)?(?:m\.)?youtube\.com\/watch\/([a-zA-Z0-9_-]+)/

and in typescript:

export function getVideoIdFromYoutubeUrl(url: string) {
  const regex =
    /(?:youtu\.be\/|youtube\.com(?:\/(?:[^\/\n\s]+\/\S+\/|(?:v|e(?:mbed)?)\/|\S*?[?&]v=|shorts\/)|youtu\.be\/|embed\/|v\/|m\/|watch\?(?:[^=]+=[^&]+&)*?v=))([^"&?\/\s]{11})/gm;

  const edgeCasesRegex = /(?:https?:\/\/)?(?:www\.)?(?:m\.)?youtube\.com\/watch\/([a-zA-Z0-9_-]+)/;

  let result = regex.exec(url);

  if (!result) result = edgeCasesRegex.exec(url);

  return result[1];
}

Mine works: https://gist.github.com/rodrigoborgesdeoliveira/987683cfbfcc8d800192da1e73adc486?permalink_comment_id=5055166#gistcomment-5055166

if you are using JS, TS, or Angular u can use this works fine for me

getYoutubeVideoId(url) {
    // Regular expression to match different YouTube URL formats, including shorts
    const regExp = /(?:youtube\.com\/(?:[^\/\n\s]+\/\S+\/|(?:v|e(?:mbed)?|shorts)\/|\S*?[?&]v=)|youtu\.be\/)([a-zA-Z0-9_-]{11})/i;
    const match = url.match(regExp);
    console.log(match && match[1] ? match[1] : null, "id", url); // For debugging purposes
    return match && match[1] ? match[1] : null;
  }

If you trying to find a regex to match all format YT links try this

I write it for myself, it's works for me.
I use Js.

I love this when rickroll is covered

Another approach is to first verify that the string contains a YouTube domain:

/(?:https?:\/\/(www.|m.)?)?(?<domain>youtu.be|youtube.com)(?:\/)/

Then pick out the data you're looking for. For me, I'm only interested in the video ID:

/((?:\/|v=|vi=|v%)(?<id>([\-\w]){10,14}))/

Thanks @rodrigoborgesdeoliveira for your URL list!
