Hello,
We followed the procedure in [https://www.wowza.com/docs/how-to-test-aes-encryption-for-apple-hls-streams](https://www.wowza.com/docs/how-to-test-aes-encryption-for-apple-hls-streams) but at the point 9, we succeeded in video chunk reading contrary to what it was expected.
With our Wowza-DVR, we created a video without encryption (cupertinoEncryptionAPIBased to false) and we want to read it with a HLS encryption.
For the tests, we are reading video with VLC (type = httpstreamer).
What did we miss?
A few complementary informations:
- We see in our logs that we see just one time in onHTTPCupertinoEncryptionKeyLiveChunk that we override (IModuleOnHTTPCupertinoEncryption interface). So, the CupertinoEncInfo is set only once.
- On VLC Message side, we noticed that the decode URL is never called.
- In our Wowza-dvr Application.xml, we have:
```auto
live
cupertinoEncryptionAPIBased
true
Boolean
```
Example of our Java logs when reading the video :
```auto

Hi @Chloe Gouteron, sorry for the delayed response, I was out of the office. This is interesting and thanks for sharing what you have tried and what the logs showed.
Did you get a final solution for your support ticket 320629?
I spoke with our engineers and they would like to view all the logs and files to run some tests.They can only do this through a support ticket however and you can submit it here:
[https://www.wowza.com/support/open-ticket](https://www.wowza.com/support/open-ticket)
But, I see you submitted one for something similar. Please let me know. Thanks.
