getting the youtube id from a link

Question

I got this code to get the youtube id from the links like www.youtube.com/watch?v=xxxxxxx

  URL youtubeURL = new URL(link);
  youtubeURL.getQuery();

basically this will get me the id easily v=xxxxxxxx

but I noticed sometime youtube links will be like this

http://gdata.youtube.com/feeds/api/videos/xxxxxx

I am getting the links from a feed so do I need to build a regex for that or theres a parser to get that for me ?

Answer 1

Got a better solution from this link.

Use the following method to get the videoId from the link.

YoutubeHelper.java

import com.google.inject.Singleton; 

import java.util.regex.Matcher;
import java.util.regex.Pattern;

@Singleton 
public class YouTubeHelper { 

    final String youTubeUrlRegEx = "^(https?)?(://)?(www.)?(m.)?((youtube.com)|(youtu.be))/";
    final String[] videoIdRegex = { "\\?vi?=([^&]*)","watch\\?.*v=([^&]*)", "(?:embed|vi?)/([^/?]*)", "^([A-Za-z0-9\\-]*)"};

    public String extractVideoIdFromUrl(String url) {
        String youTubeLinkWithoutProtocolAndDomain = youTubeLinkWithoutProtocolAndDomain(url);

        for(String regex : videoIdRegex) {
            Pattern compiledPattern = Pattern.compile(regex);
            Matcher matcher = compiledPattern.matcher(youTubeLinkWithoutProtocolAndDomain);

            if(matcher.find()){
                return matcher.group(1);
            } 
        } 

        return null; 
    } 

    private String youTubeLinkWithoutProtocolAndDomain(String url) {
        Pattern compiledPattern = Pattern.compile(youTubeUrlRegEx);
        Matcher matcher = compiledPattern.matcher(url);

        if(matcher.find()){
            return url.replace(matcher.group(), "");
        } 
        return url;
    } 
} 

Hope this helps.

This was worked for me

public static String getYoutubeVideoId(String youtubeUrl) {
    String videoId = "";
    if (youtubeUrl != null && youtubeUrl.trim().length() > 0 && youtubeUrl.startsWith("http")) {

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

    }
    return videoId;
}

This will work me and simple

public static String getVideoId(@NonNull String videoUrl) {
    String reg = "(?:youtube(?:-nocookie)?\\.com\\/(?:[^\\/\\n\\s]+\\/\\S+\\/|(?:v|e(?:mbed)?)\\/|\\S*?[?&]v=)|youtu\\.be\\/)([a-zA-Z0-9_-]{11})";
    Pattern pattern = Pattern.compile(reg, Pattern.CASE_INSENSITIVE);
    Matcher matcher = pattern.matcher(videoUrl);

    if (matcher.find())
        return matcher.group(1);
    return null;
}
