Playback HLS AES-128 .m3u8

Hello,
I am building a Streaming Tizen Smart tv app but i am getting an issue with the HLS content because is encrypted with AES-128.
I am using AVPLay GitHub - SamsungDForum/SampleWebApps-PlayerAvplay.
Checking the documentation seems to be supported, but is not working in the emulator neither in a real tv device.
Smart TV - Build | Samsung Developers

  1. I would want to know if Samsung 2016, 2017, 2018, 2019 and 2020 is supporting AES-128.
  2. Do you have an example of AES-128 with HLS?

Thank you,
