persistent license renewal

[odedhutzler]

Hi,

Do you have an API for persistent (offline) license renewal? i want to renew the license without download the video again.

Thanks

First, I believe there is no way to renew an offline license. The only option would be to delete the old license and download a new license. But trying to swap out the license is unsupported. We might be able to add an API to reset the licences of a piece of content, but it would require storing the pssh data so we can make another license request later.

@TheModMaker alright, thanks.

so in the meanwhile, i am trying to create a renewal mechanism by myself.
I created a function that gets the manifest from the DB, then i created a drmEngine and:

session.load(manifestDb.sessionID) //old session ID
.then(()=>return session.remove()) //removing the old session
.then(()=>return loadInternal(...)) // which should create a new license session.
...
.then(()=> this.storageEngine_.updateManifest // with the new sessionID & expiration.

that seems to work.

however, when i am trying to load the offline asset, i get

Shaka Error DRM.FAILED_TO_CREATE_SESSION (Rejected with system code (70))

after i refresh the page the offline asset plays without any issue.

any thoughts?
What is system code 70?

I consulted with the Widevine CDM folks, and system code 70 seems to indicate that you are trying to load a session which is already in use. The session created by loadInternal() might need to be closed at the end of your Promise chain.

@joeyparrish cool! i will try that and let you know.

We're still open to a PR. We're not working on this internally at the moment.
