Playing excrypted URL on the fly

[belike-priyesh]

Hi @moagrius
Is there any possibility to play encrypted video URL on the fly? Encryption follows is AES/CTR/NoPadding
The method mentioned by you in this repo is working fine with local encrypted video if I put the same video from URL to local storage.
The code that I have tried is below, the rest of the code is a copy of DefaultHTTPDataSource in exoplayer package
SecretKeySpec sks = new SecretKeySpec(key, "AES"); Cipher cipher = Cipher.getInstance("AES/CTR/NoPadding"); cipher.init(Cipher.DECRYPT_MODE, sks, ivParameterSpec); InputStream inputStream = connection.getInputStream(); this.inputStream = new StreamingCipherInputStream(inputStream, cipher);

Hi,
So I just did like what you did by adding
.inputStream = new StreamingCipherInputStream(inputStream, cipher);
but the problem is that I can not figure the best way to do "Skipping" when I seek the player backward it just got broken!

I've figured that in the Local File playing we use inputStream.forceSkip(bytesToSkip)
but I can not implement it in skipInternal() method in DefaultHTTPDataSource.

So, can you help me with that?

I also want to play encrypted video on the fly, I don't want to download it. If anyone has done this then please share sample demo.
I tried but even connection.getInputStream() not working for me.

@vickyexpert @issamabuaqlien , I know it might be too late to answer your question but for the sake of others who might need to implement the same mechanism, I've posted a fully working custom DataSource in here which plays an encrypted Audio File from a remote serve on the fly. It also handles backward and forward seeking appropriately.
