What did you do?
I tried to play DRM encrypted video on Samsung Internet Browser. It works well with Shaka 3.1.x but not working at all from 3.2.x
What actually happened?
DRM encrypted content works well with Shaka Player 3.1.x on Samsung Internet Browser.
I tested all higher versions, from 3.2.x and I receive 3016: Shaka Error MEDIA.VIDEO_ERROR (3,,)
I know that Samsung Browser is not officially supported, but it satisfies requirements and some of our users still using it to play videos (since we don't have an app for Tizen yet).
I guess there was some significant change in decoding content in 3.2, since 3.1 branch is free of this error.
Maybe there is a workaround with a new setting?
The last debug message on the console before the error in v3.3.8 is:
Key status changed for session
(and critical 3016 after this).
I would like to upgrade Shaka Player finally to 4.x, but we have to keep 3.1 only for Samsung Tizen Browser because of this bug.
The big change in v3.2 that might be relevant is the adoption of the MediaCapabilities API. You can opt-in to MediaCapabilities in v3.1 with player.configure('useMediaCapabilities', true). Please try that and let us know if this triggers the same issue on v3.1. If so, we can investigate the MediaCapabilities polyfill on Samsung browser. I believe I have a copy of that available on Android.
Yes! I guess it's MediaCapabilities API.
The player.configure('useMediaCapabilities', true) setting triggers 3016 error on Shaka v3.1.x as well.
I'm going to guess that this is a bug in the MediaCapabilities implementation of Samsung Browser. We may be able to work around it by forcing the use of a polyfill. Sadly, this is something we have had to do on many platforms to date.
I initially assumed we were talking about the Samsung Browser on Android, but I can't reproduce the issue there. Does this only occur on Tizen? I see now that you mentioned Tizen 5.
I don't have access to a Tizen TV at home right now, and the one we have in the lab isn't running Tizen 5. Can you please test this patch in Shaka v3.2+ or the latest code from the repo's main branch?

Thanks!
@joeyparrish just to let you know: version 4.2.0 works like a charm on my Tizen 5.0.
Great! I think PR #4396 solved it. That was cherry-picked to v3.2.11, v3.3.9, v4.0.5, and v4.1.3. It also appears in the latest feature release v4.2.0.
