Android based YouTube url extractor

These are the urls to the YouTube video or audio files, so you can stream or download them. It features an age verification circumvention and a signature deciphering method (mainly for vevo videos).

• Builds:
• Dependency: js-evaluator-for-android

Gradle

To always build from the latest commit with all updates. Add the JitPack repository:

repositories {
    maven { url "https://jitpack.io" }
}

And the dependency:

implementation 'com.github.HaarigerHarald:android-youtubeExtractor:master-SNAPSHOT'

Usage

It's build around an AsyncTask. Called from an Activity you can write:

String youtubeLink = "http://youtube.com/watch?v=xxxx";

new YouTubeExtractor(this) {
    @Override
    public void onExtractionComplete(SparseArray<YtFile> ytFiles, VideoMeta vMeta) {
        if (ytFiles != null) {
            int itag = 22;
	    String downloadUrl = ytFiles.get(itag).getUrl();
        }
    }
}.extract(youtubeLink);

The ytFiles SparseArray is a map of available media files for one YouTube video, accessible by their itag value. For further infos about itags and their associated formats refer to: Wikipedia - YouTube Quality and formats.
