We are testing ROKU devices with live HLS Widevine encrypted content using Shaka packager. We noticed that while key rotation works well with ROKU devices with CDM version 15.3.0, it fails with those that have CDM version 16.4.0.
Does 16.4.0 change anything on key rotation implementation details, or this is a known issue with ROKU player?
We tested with both Roku Ultra 4660X (CDM version 15.3.0), and Roku Ultra 4640X (CDM version 16.4.0). The later, starts correctly video/audio rendering at tune, at the second key update video rendering fails.
- Shaka packager version 2.4.3 using Widevine KeyServer.
- Signer widevine-test.
- License server UAT (Test).
- Protection scheme cenc (CTR)
- key rotation period 10 minutes.
