Issue with HLS AES encrypted on DVR playback

Hello,

We followed the procedure in 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:

<StreamType>live</StreamType>

<Property>
   <Name>cupertinoEncryptionAPIBased</Name>
   <Value>true</Value>
   <Type>Boolean</Type>
</Property>

Example of our Java logs when reading the video :
