What actually happened?
We are having problems playing HLS/Fairplay content with Shaka V4.
The license request towards the license server seems to work as expected. We originally had issue with that the the defaultInitDataTransform has changed so that skd:// was no longer removed in the data sent in the license request (which V3 does). In addition to successful license requests we also see that manifests and media segments are retrieved from our server but playback never starts. After a long period of time we get an error 3016 saying that media cannot be decoded. We can play the same streams using V3 and we can also play unencrypted versions of the streams using V4.
Comparing the logs between V3 and V4 we see differences when it comes to implementation of MediaKeys. If I understand correctly, V4 is using the EME for handling the media keys where as V3 is using a poly-filled version?
We are out of ideas on how to troubleshoot this further. Do you have any suggestions?
Is it possible to configure the implementation of MediaKeys in V4 to at least test to see if that is the root cause?
