What did you do?
Update from 3.1 to 3.2.0.
Play any content.

What did you expect to happen?
The content should be played with no code changes.
No breaking changes were found in the releases (at least what I've read).

What actually happened?
The player.load() method rejects with an error object 6001: REQUESTED_KEY_SYSTEMS_UNAVAILABLE (see attached image).
3.1 shaka player versions works well. I've checked this error in the FAQ:

• We are using both PlayReady and Widevine Alpha.
• We are not using Storage.
• Yes we are developing on unsecure origins but we tried on secure environment (prod) and we could reproduce the issue. But if this would be the issue, I couldn't understand why in 3.1 the player works well.

We want to update to 3.2 or newer versions, but this issue is blocking us a lot.

[joeyparrish]

The major change from v3.1 to v3.2 is the MediaCapabilities API. It went from opt-in on 3.1 to required in 3.2+. My guess is that Tizen's has an implementation of MediaCapabilities, but it is broken.

This sounds like the same thing as #4357

Can you please try the patch I suggested in #4357 (comment)? If that works for you, we'll get it out in an update ASAP. But we don't have any way to test that ourselves, as our particular Tizen TV isn't affected (probably too old to have MCap at all).

[iskewedI]

Thanks for the response.
So I've tried that workaround in v4.1.2, I had to do some other work because the shaka.util.Platform doesn't exist yet, nor some other methods so with some tweaks and polyfills (copied directly from the main branch) I manage to stop the errors and make it work, and the player worked well! It didn't throw the 6001 error anymore.
Its right to call the shaka.polyfill.MediaCapabilities.install()method from outside? Because if I don't do that, shaka itself doesn't call it.

[koenoe]

Similar thing happens in WebOS 5.x, as it has a native implementation of MediaCapabilities, but isn't reliable. WebOS 5.x supports Playready SL3000, but returns false on support of com.microsoft.playready.recommendation. Would be good to add shaka.util.Platform.isWebOS() to the patch as well I think.

[avelad]

@koenoe I think it's better to block the versions that don't work. Does WebOS 6.x or WebOS 22 work correctly? (https://webostv.developer.lge.com/discover/specifications/web-engine/)

I am open to blocking specific versions.

[koenoe]

@avelad I don't have the ability to test on WebOS 6.x or WebOS 22 at the moment, but will try to do that asap

[koenoe]

@avelad I've just tested it on WebOS 6.3.1 and it doesn't work correctly either. I expect it to not work on WebOS 22 either, as the MediaCapability API in Tizen and WebOS just isn't very reliable in my experience.

[avelad]

Ok, tomorrow I’ll send a fix for it! Thanks!

[iskewedI]

Thank you @avelad. So if I understand you well, you are going to fix this in the 3.2 version right?
If that's the case, if we want to update to a newer version like v4, we would need to do this workaround for our side?

[joeyparrish]

I'll cherry-pick @avelad's fix to all the branches we are currently maintaining (v3.2, v3.3, v4.0, v4.1). See also https://github.com/shaka-project/shaka-player/blob/main/maintained-branches.md
