What did you do?

I load a custom app with Shaka player setup to play an MPD asset with Playready DRM onto a Sony TV (Amaebi Gen5, EME version).

What did you expect to happen?
I expect playback to start and continue playing without any issues.

What actually happened?

Playback begins most of the time, but with out of sync usable variants. Fatal RESTRICTIONS CANNOT BE MET / 4012 error is emitted even though video seems to be playing in some cases. Sometimes only audio track can be heard without any frames getting rendered on the screen.

Are you planning to send a PR to fix it?
Yes
