Figured this question wasn't here for Java, in case you need to do it in Java here's a way

public static String extractYTId(String ytUrl) {
    String vId = null;
    Pattern pattern = Pattern.compile(
                     "^https?://.*(?:youtu.be/|v/|u/\\w/|embed/|watch?v=)([^#&?]*).*$", 
                     Pattern.CASE_INSENSITIVE);
    Matcher matcher = pattern.matcher(ytUrl);
    if (matcher.matches()){
        vId = matcher.group(1);
    }
    return vId;
}

Works for URLs like (also for https://...)

You don't need to escape / in Java ore regex. Also # & are not regex metacharacters so you don't need to escape them. You only need to escape ? but only if it is outside of character class [..] so here you don't need to.
I edited the answer to remove unnecessary escaping and enforced case insensitive matching.
This method returns null
does not work for https://m.youtube.com/watch?feature=youtu.be&v=123 types of links
Does not work for some urls you've list, and also for https://www.youtube.com/watch?v= 0zM4nApSvMg&feature=youtu.be

Previous answers don't work for me.. It's correct method. It works with www.youtube.com and youtu.be links.

private String getYouTubeId (String youTubeUrl) {
    String pattern = "(?<=youtu.be/|watch\\?v=|/videos/|embed\\/)[^#\\&\\?]*";
    Pattern compiledPattern = Pattern.compile(pattern);
    Matcher matcher = compiledPattern.matcher(youTubeUrl);
    if(matcher.find()){
        return matcher.group();
    } else {
        return "error";  
    }
}

@Devon this is a String Pattern, you can use with any language which support this, such as Java, C#...
Best for those look for regex, but not for those who look for full code.
Didn't understand. Please update your answer. Because Youtube updated live videos with youtube.com/live/eLlxrBmD3H4
@AhamadullahSaikat Live video updated
Can you add support for YouTube shorts too?

To me, for the sample links you posted, this regex looks more precise (capturing the ID to Group 1): 

https?://(?:www\.)?youtu(?:\.be/|be\.com/(?:watch\?v=|v/|embed/|user/(?:[\w#]+/)+))([^&#?\n]+)

On the demo, see the capture groups in the bottom right pane. However, for the second match, not entirely sure that this is a correct ID as it looks different from the other samples—to be tweaked if needed.

In code, something like:

Pattern regex = Pattern.compile("http://(?:www\\.)?youtu(?:\\.be/|be\\.com/(?:watch\\?v=|v/|embed/|user/(?:[\\w#]+/)+))([^&#?\n]+)");
    Matcher regexMatcher = regex.matcher(subjectString);
    if (regexMatcher.find()) {
        VideoID = regexMatcher.group(1);
    }

Fixed yours for https http(?:s)?://(?:www\.)?youtu(?:\.be/|be\.com/(?:watch\?v=|v/|embed/|user/(?:[\w#]+/)+))([^&#?\n]+)

        if (matcher.matches()) {

OP asked for a solution in JAVA
Does not work with the last Url.

Tried the other ones but failed in my case - adjusted the regex to fit for my urls

public static String extractYoutubeVideoId(String ytUrl) {

        String vId = null;

        String pattern = "(?<=watch\\?v=|/videos/|embed\\/)[^#\\&\\?]*";

        Pattern compiledPattern = Pattern.compile(pattern);
        Matcher matcher = compiledPattern.matcher(ytUrl);

        if(matcher.find()){
            vId= matcher.group();
        }
        return vId;
    }

This one works for below url's

Using regex from Tấn Nguyên:

public String getVideoIdFromYoutubeUrl(String url){
    String videoId = null;
    String regex = "http(?:s)?:\\/\\/(?:m.)?(?:www\\.)?youtu(?:\\.be\\/|be\\.com\\/(?:watch\\?(?:feature=youtu.be\\&)?v=|v\\/|embed\\/|user\\/(?:[\\w#]+\\/)+))([^&#?\\n]+)";
    Pattern pattern = Pattern.compile(regex, Pattern.CASE_INSENSITIVE);
    Matcher matcher = pattern.matcher(url);
    if(matcher.find()){
        videoId = matcher.group(1);
    }
    return videoId;
}

    Pattern pattern = Pattern.compile(reg, Pattern.CASE_INSENSITIVE);
    Matcher matcher = pattern.matcher(videoUrl);

    if (matcher.find())

Just pass youtube link in below function , it will detect all type of youtube url

    public static String getYoutubeID(String youtubeUrl) {

    if (TextUtils.isEmpty(youtubeUrl)) {
        return "";
    }
    String video_id = "";

    String expression = "^.*((youtu.be" + "\\/)" + "|(v\\/)|(\\/u\\/w\\/)|(embed\\/)|(watch\\?))\\??v?=?([^#\\&\\?]*).*"; // var regExp = /^.*((youtu.be\/)|(v\/)|(\/u\/\w\/)|(embed\/)|(watch\?))\??v?=?([^#\&\?]*).*/;
    CharSequence input = youtubeUrl;
    Pattern pattern = Pattern.compile(expression, Pattern.CASE_INSENSITIVE);
    Matcher matcher = pattern.matcher(input);
    if (matcher.matches()) {
        String groupIndex1 = matcher.group(7);
        if (groupIndex1 != null && groupIndex1.length() == 11)
            video_id = groupIndex1;
    }
    if (TextUtils.isEmpty(video_id)) {
        if (youtubeUrl.contains("youtu.be/")  ) {

Combining a couple of methods, to cover as many formats as possible, is recommended.

String ID1 = getYoutubeID1(url); regex 1
String ID2 = getYoutubeID2(url); regex 2
String ID3 = getYoutubeID3(url); regex 3

then, using an if/switch statement to choose a value that isn't null and is valid.

This will work on two kinks of youtube video urls either direct or shared URL.

Direct url: https://www.youtube.com/watch?v=XXXXXXXXXXX

Shared url: https://youtu.be/XXXXXXXXXXX

This is very similar to the link posted in your question.

String url = "https://www.youtube.com/watch?v=wZZ7oFKsKzY";
if(url.indexOf("v=") == -1) //there's no video id
    return "";
String id  = url.split("v=")[1]; //everything before the first 'v=' will be the first element, i.e. [0]
int end_of_id = id_to_end.indexOf("&"); //if there are other parameters in the url, get only the id's value
if(end_index != -1)
     id = url.substring(0, end_of_id);
return id;

Without regex :

String url - "https://www.youtube.com/watch?v=BYrumLBuzHk"
String video_id = url.replace("https://www.youtube.com/watch?v=", "")

So now you have a video ID in string video_id.

What if there are other query values after v? What if they are using the shortened youtube links?
