A video codec for the cloud that’s worth trying


How to decode the latest videos using the popular open source Java and Python code editor.

In this article, we’re going to show you how to decode YouTube videos using JWT encoded content.


Create a JWT Encryption Key for the Video Codec You can create a Jwt Encryption key by using the Encoder class, and then use the Encoders.create() method.

The encode() method takes a String and returns a new JwtEncryptionKey object that contains the EncodedString, the EncodingKey and the EncryptedString.

Let’s start with creating a new key.

Open the Encodes.java file and create a new file named encode.json in the “videos” folder.

Save the file as encode.js and then open it with the following command.

jwt encode.

json You’ll see a bunch of JSON, but for now let’s just read through it.

The first field that’s marked with a dash is the EncryptionKey, which we’re using for this tutorial.

If you want to use a different Encryption, simply change the “encodingKey” field in the Encode class to a different one.

You can see the fields marked with an asterisk (*) at the end of the JWT encoding field.

Next up is the JwtSignature field.

If your JWT is encrypted with a random key, you should have no problem with decrypting the content of your video stream.

If not, you can generate a random one with the encode() methods and then verify that the JsonObject has the same signature as the JwtsSignature.

If it doesn’t, try a different random key.

Lastly, we can verify that our JWT has been decrypted by passing the JSON payload to the encode.decode() method, which will return a Jwtran object.


Create an Encoding for YouTube Videos We’re going back to the videos folder and create an Encoder object for the YouTube video codec that we just created.

This encoder will be used to decode all of the YouTube videos that we’ve created so far.

Open up the Encades.java class, add the following code to it and then save the file.


decode YouTube.js If you’re using a Python version of Jwt, make sure to add a JWtran to the Encs.create method.


Create the JWTran Encoding We’re just going to need to create a single JWToken to encode YouTube videos, so open up Encades\Encoder.java and add the JToken class to it.

The JToken.createFromJwt method will create the new JToken object from the content we’ve generated.


Check if YouTube is Decrypted Let’s check YouTube is decrypted using the YouTube Decoder class.

Open Encodes\Encoders and create another Encoder.

The Decoder.decodes() method will take a String that’s the content for the video we’re encoding and a JToken as the payload.

If the Jtoken has a unique signature, it should be generated using the encode().decode method.

If so, the Decoder.getJSON() method should return the same content.

Open Decoder.java, add this code to the class: class Decoder(Encoder): def encode(self, content): if not content.encoded: return “YouTube” else: return content.json.decoded return “?” class DecoderVideoCodec( Decoder): def decode(self): if content.encrypted: return YouTube.json else: print “YouTube is decoded” return “” def decodeVideo(self:Content): if self.encrypted: return JToken(“YouTube” + content.decrypted) else: decodeVideo() return “?video={” + encode(content) + “}” def decodeString(self.decoder: DecoderVideoDecoder): if isinstance(self._decoder, DecoderVideo): print “Decoded content:” + encodeString(content.decoding) else : print “Not decoded content.”

The encodeString() method returns a JObject that contains a JSON object that describes what the content in the video is.

You can use this object to determine whether the video has been encrypted, and you can verify the content by looking at the JObjects property in the JTokens class.

You might want to inspect the content to see if there’s anything that is different between the two encodings.

This is a handy way to make sure you don’t accidentally encrypt content you haven’t decoded.


Check YouTube is Encrypted You’re probably wondering why YouTube is encrypted.

The reason is that the content is decryption protected.

YouTube will not encode videos if the content doesn’t match the content type specified in the certificate. If there
