How to save licenses so that player can play local widevine content offline #208

Closed yukihiro-m-play closed 3 years ago

yukihiro-m-play commented 3 years ago

Player request license information every time when player played widevine content saved locally. If player do not request license information, the following error will occur.

Error Message:

Domain=ShakaPlayerErrorDomain Code=6008 "Shaka Error DRM.LICENSE_RESPONSE_REJECTED (Unknown internal error.)" 
UserInfo={NSLocalizedDescription=Shaka Error DRM.LICENSE_RESPONSE_REJECTED (Unknown internal error.), ShakaPlayerErrorSeverityKey=2, ShakaPlayerErrorCategoryKey=6}

We have confirmed that player does not reacquire license information when playing widevine content downloaded with ShakaPlayerStorage. We think this behavior is different from the #201 answer. If player dont need to require license info with playing widevine content downloaded with ShakaPlayerStorage, is there a way to play without reacquiring license info like ShakaPlayerStorage do?

If you want to store offline content, you should use ShakaPlayerStorage. You can't just store licenses to reuse them. Using ShakaPlayerStorage will cause us to request an offline license and the CDM will store the license persistently. We don't support requesting or reusing offline licenses for streaming playbacks.
