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!

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" },

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 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/
