A helper to extract the streaming URL from a YouTube video using RxJava and Retrofit

Add this in your root build.gradle file (not your module build.gradle file):

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

Then, add the library to your project build.gradle

dependencies {
    implementation 'com.github.Commit451:YouTubeExtractor:latest.version.here'
}

If you are familiar with RxJava, the extractor returns a Single:

//create one of these and reuse it for performance reasons
YouTubeExtractor extractor = YouTubeExtractor.create();
extractor.extract("9d8wWcJLnFI")
    .subscribeOn(Schedulers.io())
    .observeOn(AndroidSchedulers.mainThread())
    .subscribe({ extraction ->
        bindVideoResult(extraction)
    }, { t ->
        onError(t)
    })

Note: the above example also requires RxAndroid for AndroidSchedulers

You can also extract the result right away:

// Don't do this on the main thread!
val extraction = extractor.extract("9d8wWcJLnFI")
    .blockingGet()

This library was only created to extract video stream URLs from YouTube, not provide a video player. ExoMedia is a great library for playing the video streams to the user. See the sample app for an example.

This library uses OkHttp, Moshi and Rhino under the hood, so you may need to apply their ProGuard rules.

This library is intentionally being kept pretty lightweight, with the main priority being the stream URLs.

Known Failure Points:

• Videos that are age restricted
• Videos that are audio only
