Regular expression for youtube links

Does someone have a regular expression that gets a link to a Youtube video (no开发者_如何学Got embedded object) from (almost) all the possible ways of linking to Youtube?

I think this is a pretty common problem and I'm sure there are a lot of ways to link that.

A starting point would be:

• http://www.youtube.com/watch?v=iwGFalTRHDA
• http://www.youtube.com/watch?v=iwGFalTRHDA&feature=related
• http://youtu.be/iwGFalTRHDA
• http://youtu.be/n17B_uFF4cA
• http://www.youtube.com/embed/watch?feature=player_embedded&v=r5nB9u4jjy4
• http://www.youtube.com/watch?v=t-ZRX8984sc
• http://youtu.be/t-ZRX8984sc
• ... please add more possible links and/or regular expressions to detect them.

So far I got this Regular expression working for the examples I posted, and it gets the ID on the first group:

http(?:s?):\/\/(?:www\.)?youtu(?:be\.com\/watch\?v=|\.be\/)([\w\-\_]*)(&(amp;)?‌​[\w\?‌​=]*)?

---

You can use this expression below.

(?:https?:\/\/)?(?:www\.)?youtu\.?be(?:\.com)?\/?.*(?:watch|embed)?(?:.*v=|v\/|\/)([\w\-_]+)\&?

I'm using it, and it cover the most used URLs. I'll keep updating it on This Gist. You can test it on this tool.

I like @brunodles's solution the most but you can still match non video links like https://www.youtube.com/feed/subscriptions

I went with this solution

(?:https?:\/\/)?(?:www\.)?youtu(?:\.be\/|be.com\/\S*(?:watch|embed)(?:(?:(?=\/[-a-zA-Z0-9_]{11,}(?!\S))\/)|(?:\S*v=|v\/)))([-a-zA-Z0-9_]{11,})

It can also be used to match multiple whitespace separated links. The video id will be captured in the first group.

Tested with the following urls:

youtu.be/iwGFalTRHDA
youtube.com/watch?v=iwGFalTRHDA
www.youtube.com/watch?v=iwGFalTRHDA

I improved the links posted above with a friend for a script I wrote for IRC to recognize even links without http at all. It worked on all stress tests I got so far, including garbled text with barely recognizable youtube urls, so here it is:

~(?:https?://)?(?:www\.)?youtu(?:be\.com/watch\?(?:.*?&(?:amp;)?)?v=|\.be/)([\w\-]+)(?:&(?:amp;)?[\w\?=]*)?~

---

I testet all the regular expressions that are shown here and none could cover all url types that my client was using.

I built this pretty much through trial and error, but it seems to work with all the patterns that Poppy Deejay posted.

"(?:.+?)?(?:\/v\/|watch\/|\?v=|\&v=|youtu\.be\/|\/v=|^youtu\.be\/)([a-zA-Z0-9_-]{11})+"

Maybe it helps someone who is in a similar situation that I had today ;)

Piggy backing on Fanmade, this covers the below links including the url encoded version of attribution_links:

(?:.+?)?(?:\/v\/|watch\/|\?v=|\&v=|youtu\.be\/|\/v=|^youtu\.be\/|watch\%3Fv\%3D)([a-zA-Z0-9_-]{11})+

I've been having problems lately with the atttribution_link urls so i tried making my own regex that works for those too.

Here is my regex string:

(https?://)?(www\\.)?(yotu\\.be/|youtube\\.com/)?((.+/)?(watch(\\?v=|.+&v=))?(v=)?)([\\w_-]{11})(&.+)?

and here are some test cases i've tried:

http://www.youtube.com/attribution_link?a=fF1CWYwxCQ4&feature=em-uploademail&u=/watch?v=qYr8opTPSaQ

Also remember to check the string you get for your video url, sometimes it may get the percent characters. If so just do this

url = [url stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

and it should fix it.

Remember also that the index of the youtube key is now index 9.

NSRange youtubeKey = [result rangeAtIndex:9]; //the youtube key
NSString * strKey = [url substringWithRange:youtubeKey] ;

It'd be the longest RegEx in the world if you managed to cover all link formats, but here's one to get you started which will cover the first couple of link formats:

http://(www\.)?youtube\.com/watch\?.*v=([a-zA-Z0-9]+).*

The second group will match the video ID if you need to get that out.

---

(?:http?s?:\/\/)?(?:www.)?(?:m.)?(?:music.)?youtu(?:\.?be)(?:\.com)?(?:(?:\w*.?:\/\/)?\w*.?\w*-?.?\w*\/(?:embed|e|v|watch|.*\/)?\??(?:feature=\w*\.?\w*)?&?(?:v=)?\/?)([\w\d_-]{11})(?:\S+)?

Detects YouTube and YouTube Music link in any string

I took all variants from here:

https://gist.github.com/rodrigoborgesdeoliveira/987683cfbfcc8d800192da1e73adc486#file-youtubeurlformats-txt

And built this regexp (YouTube ID is in group 2):

(\/|%3D|v=|vi=)([0-9A-z-_]{11})[%#?&\s]

Check it here: https://regexr.com/4u4ud

Edit: Works for any single string w/o breaks.

I'm working with that kind of links:

http://www.youtube.com/v/M-faNJWc9T0?fs=1&rel=0

And here's the regEx I'm using to get ID from it:

"(.+?)(\/v/)([a-zA-Z0-9_-]{11})+"

This is iterating on the existing answers and handles edge cases better. (for example http://thisisnotyoutu.be/thing)

/(?:https?:\/\/|www\.|m\.|^)youtu(?:be\.com\/watch\?(?:.*?&(?:amp;)?)?v=|\.be\/)([\w‌​\-]+)(?:&(?:amp;)?[\w\?=]*)?/

here is the complete solution for getting youtube video id for java or android, i didn't found any link which doesn't work with this function

public static String getValidYoutubeVideoId(String youtubeUrl)
{
    if(youtubeUrl == null || youtubeUrl.trim().contentEquals(""))
    {
        return "";
    }
    youtubeUrl = youtubeUrl.trim();
    String validYoutubeVideoId = "";
    String regexPattern = "^(?:https?:\\/\\/)?(?:[0-9A-Z-]+\\.)?(?:youtu\\.be\\/|youtube\\.com\\S*[^\\w\\-\\s])([\\w\\-]{11})(?=[^\\w\\-]|$)(?![?=&+%\\w]*(?:['\"][^<>]*>|<\\/a>))[?=&+%\\w]*";
    Pattern regexCompiled = Pattern.compile(regexPattern, Pattern.CASE_INSENSITIVE);
    Matcher regexMatcher = regexCompiled.matcher(youtubeUrl);
    if(regexMatcher.find())
    {
        try
        {
            validYoutubeVideoId = regexMatcher.group(1);
        }
        catch(Exception ex)
        {
        }
    }
    return validYoutubeVideoId;
}

This is my answer to use in Scala. This is useful to extract 11 digits from Youtube's URL.

"https?://(?:[0-9a-zA-Z-]+.)?(?:www.youtube.com/|youtu.be\S*[^\w-\s])([\w -]{11})(?=[^\w-]|$)(?![?=&+%\w](?:[\'"][^<>]>|))[?=&+%\w-]*"

def getVideoLinkWR: UserDefinedFunction = udf(f = (videoLink: String) => {
    val youtubeRgx = """https?://(?:[0-9a-zA-Z-]+\.)?(?:youtu\.be/|youtube\.com\S*[^\w\-\s])([\w \-]{11})(?=[^\w\-]|$)(?![?=&+%\w]*(?:[\'"][^<>]*>|</a>))[?=&+%\w-./]*""".r
    videoLink match {
        case youtubeRgx(a) => s"$a".toString
        case _ => videoLink.toString
    }
}

This should work for almost all youtube links when extracting from a string:

((?:https?:)?\/\/)?((?:www|m)\.)?((?:youtube\.com|youtu.be))(\/(?:[\w\-]+\?v=|embed\/|v\/)?)([\w\-]{10}).\b

    var isValidYoutubeLink: Bool{
        // working for all the youtube url's
        NSPredicate(format: "SELF MATCHES %@", "(?:http?s?:\\/\\/)?(?:www.)?(?:m.)?(?:music.)?youtu(?:\\.?be)(?:\\.com)?(?:(?:\\w*.?:\\/\\/)?\\w*.?\\w*-?.?\\w*\\/(?:embed|e|v|watch|.*\\/)?\\??(?:feature=\\w*\\.?\\w*)?&?(?:v=)?\\/?)([\\w\\d_-]{11})(?:\\S+)?").evaluate(with: self)

With this Javascript Regex, the first capture is a video ID :

^(?:https?:)?(?:\/\/)?(?:www\.)?(?:youtu\.be\/|youtube(?:\-nocookie)?\.(?:[A-Za-z]{2,4}|[A-Za-z]{2,3}\.[A-Za-z]{2})\/)(?:watch|embed\/|vi?\/)*(?:\?[\w=&]*vi?=)?([^#&\?\/]{11}).*$
