What did you do? Tried to play Widevine content with videoRobustness = SW_SECURE_DECODE in Shaka config and content key “security_level = 2”(SW_SECURE_DECODE) in the license.

What did you expect to happen? The content to play, based on EME configuration content type and video robustness level promises resolving, (see attached screen grab)

What actually happened? Shaka Error code 4012 with restrictedKeyStatus of ‘internal-error’ (See attached Console screen grab)

I am able to play the content with video robustness and key security level of SW_SECURE_CRYPTO

Thanks!

With Chrome 85 stable on Windows, I see error 6001 (REQUESTED_KEY_SYSTEM_CONFIG_UNAVAILABLE), rather than 4012 (RESTRICTIONS_CANNOT_BE_MET). If the requested robustness level can’t be satisfied, 6001 would be expected. But it’s not clear why you got 4012 instead.

I’ll double-check with the Chrome CDM team to see if SW_SECURE_DECODE is expected to work for video on desktops.

Thanks, Xiaohan, good to hear from you, too! Please say hi to everyone from me.

After more testing yesterday I was worried that the single key was the issue. The partner we are working with currently does not support multi-key. I’ve been working with them to add support, hopefully they will have it soon.

I will use SW_SECURE_CRYPTO for now and close this issue. Thanks to you and @joeyparrish !
