- 15:20:02 [jasonlewis]
- David: there may be some issue of replay attacks, but this is responsibility of CDM
- 15:21:05 [jasonlewis]
- Adrian: my preference is to keep things as simple as possible. Haven't seen a compelling enough reason to move away from single initData. Prefer to keep existing structure until there is a hard requirement needing this to change.
- 15:21:06 [paulc]
- ack markw
- 15:21:32 [yang]
- agree with Adrian
- 15:21:51 [jasonlewis]
- Mark W: There is a scenario with multiple calls and multiple keys.
- 15:22:29 [jasonlewis]
- Mark W: Question is how to coordinate these requests..as a bundle? then there will need to be more information from initData
- 15:22:54 [Martin]
- +Martin
- 15:23:06 [Martin]
- q+
- 15:23:08 [Martin]
- if an initData and key request map to a single request / transaction then a one-to-one mapping is simpler and there is no reason multiple KIDs can't be included in a single "key request"
- 15:23:12 [jasonlewis]
- Mark W: Impact is whether you can write generic application without knowledge of how media keys and structure were handled in the files
- 15:23:21 [paulc]

- q+
- 15:23:42 [paulc]
- ack markw
- 15:23:45 [jasonlewis]
- Martin: It seems one-to-one mapping is simpler
- 15:24:14 [jasonlewis]
- Mark W: issue is that initData may not actually require delivery of new key
- 15:24:49 [jasonlewis]
- Mark W: Application needs to know if it needs to create to be a session
- 15:25:04 [jasonlewis]
- Paul: What does current spec say about this?
- 15:25:07 [yang]
- q+
- 15:25:22 [ddorwin]
- the current spec assumes one session at a time I believe
- 15:25:23 [paulc]
- ack yang
- 15:25:24 [jasonlewis]
- Mark W: Does say anything about key exchange if CDM already knows the key data

- 15:26:12 [paulc]
- ack adrian
- 15:26:20 [markw]
- q+
- 15:27:04 [yang]
- we do not need multiple needkey event in 1 session,even iif we support multiple initdata in one session
- 15:27:39 [yang]
- because it is meaningless for application to see the following needkey event because we only need 1 key in this session.
- 15:28:17 [jasonlewis]
- Andrian: Mark outlined one scenario that was possible. But are we ok with keeping it simple for now until a hard use case arises that justifies this
- 15:28:29 [jasonlewis]

- Mark V: if we applied the initData in createNewSession method...that would give CDM option to decide whether new data would be needed
- 15:30:24 [jasonlewis]
- David: Like this
- 15:31:08 [jasonlewis]
- Adrian: Have questions about this...and general object oriented discussion
- 15:31:14 [markw]
- createNewSession would return an existing session object if no new message exchange was required based on the provided initData
- 15:31:29 [jasonlewis]
- Topic: object-oriented design representing sessions as objects
- 15:31:34 [paulc]
- http://lists.w3.org/Archives/Public/public-html-media/2012Jun/0054.html
- 15:31:39 [markw]
- we would still need generateKeyRequest() to trigger the events as we need time to register event handlers
- 15:31:44 [ddorwin]
- One question is whether generateKeyRequest() should create the session object or be a method on that object. Having it create the object is attractive because it enforces calling order without explicit checks.
- 15:31:45 [adrianba]
- q+
- 15:33:29 [jasonlewis]
- David: if we did have createSession with initData ... and the CDM returns session... There may be an issue if this is asynchronous in the CDM
- 15:33:54 [ddorwin]
- The biggest problem with geneerateKeyRequest() creating the object is that it requires the following pattern:
- 15:33:54 [ddorwin]
- var obj = doSomethingThatFiresEventFoo();
- 15:33:54 [ddorwin]
- obj.onfoo = myhandler;
- 15:33:54 [ddorwin]
- In other words, the constructor can fire events at the object it is creating that we want to handle.
- 15:34:47 [paulc]
- ack adrian
- 15:35:00 [jasonlewis]
- Paul: Let's please get everyone's opinion
- 15:35:21 [jasonlewis]
- Adrian: My opinion is that we should pick the object-oriented approach
- 15:35:53 [Martin]
- my opinion is we should pick the object oriented approach

- Adrian: Design we proposed allows JS to iterate through the systems that a website supports... originally in spec this was done by calling createKeyRequest multiple times.
- 15:37:33 [jasonlewis]
- s/createKeyRequest/generateKeyRequest
- 15:37:55 [jasonlewis]
- Adrian: seems that we throw away objects very quickly
- 15:38:19 [jasonlewis]
- David: If we added initData we may have been able to simply get null objects
- 15:38:53 [markw]
- What if you do support the keysystem but the initData does not contain information for that keysystem ?
- 15:39:01 [jasonlewis]
- Adrian: it will still be necessary to allow async behavior. But would like to support fast fail
- 15:39:06 [markw]
- q+
- 15:39:52 [jasonlewis]
- David: issue; we would have to start throwing errors at the object

- Mark W: What if you do support the keysystem but the initData does not contain information for that keysystem ?
- 15:41:39 [jasonlewis]
- Mark W: do you have to fire up the CDM to determine support? or can the browser do this based on initData?
- 15:41:41 [Zakim]
- -markw
- 15:42:26 [Zakim]
- +markw
- 15:42:41 [jasonlewis]
- Paul: The spec doesn't make it mandatory to spin up CDM, so this is optional from browser...but probably shoul
- 15:43:57 [adrianba]
- q?
- 15:43:59 [paulc]
- ack dd
- 15:44:08 [ddorwin]
- What type of error should occur in the case where we have to spin up the CDM?
- 15:44:08 [ddorwin]
- synchronous null session object or asynchronous keyerror at the object?
- 15:44:57 [jasonlewis]
- Mark W: seems like both; if browser can determine quickly , but also need to support async when CDM has to be started to determine it
- 15:45:02 [ddorwin]
- we can specify both types of errors are possible.
- 15:45:31 [jasonlewis]
- Paul: This isn't yet included in proposal

- David: ran into roadblock that object created also is event handler; is this pattern acceptable?
- 15:47:29 [markw]
- q-
- 15:47:33 [nixu]
- nixu has joined #html-media
- 15:47:36 [jasonlewis]
- Adrian: this is a common pattern. if you add event listener to object then events are queued. May feel odd, but it is supported by the way event handlers are implemented
- 15:47:49 [jasonlewis]
- Paul: is there another API that has similar handler
- 15:48:18 [markw]
- It still might be better for the HTMLMediaElement to be "createSession" and just remove generateKeyRequest altogether
- 15:48:19 [jasonlewis]
- Adrian: XHR is similar;
- 15:48:23 [ddorwin]
- Okay, great. I wasn't sure, but that helps a lot.
- 15:48:24 [SethHodgson]
- +1 on this being a common JavaScript idiom.
- 15:48:48 [adrianba]
- q?
- 15:49:05 [markw]
- s/HTMLMediaElement/HTMLMediaElement method
- 15:49:06 [jasonlewis]
- David: Yes, i can find the Websocket api/implementation for reference
- 15:49:54 [jasonlewis]
- David: sessionId is a part of the object, but it would have to stay not valid .. until we receive the first key response
- 15:50:40 [jasonlewis]
- Paul: a) Have we answered the questions that we've talked in email? or b) do we have enough data to decide how to implement this ?
- 15:50:48 [jasonlewis]
- David: Yes
- 15:51:07 [glenn]
- is that initData object mutable or immutable?
- 15:51:54 [SethHodgson]
- Should be, or should be spec'ed as only read @ input time
- 15:51:56 [jasonlewis]
- David: it is an input. So it's currently not exposed.
- 15:52:06 [glenn]
- but if it has members, does mutating those members mean that the changes are intended to be used?
- 15:52:10 [glenn]
- i'm on the phone, but mutede
- 15:52:16 [glenn]
- s/mutede/muted/
- 15:52:31 [jasonlewis]
- Paul: trying to clarify; is it read only?
- 15:52:39 [glenn]
- ok, so there is no initData object per se?
- 15:53:01 [adrianba]
- initData is a Uint8Array
- 15:53:09 [jasonlewis]
- David: initData is blob, that probably came from a file
- 15:53:40 [jasonlewis]
- David: session object is mutable, but properties like sessionid are read only
- 15:53:41 [adrianba]
- generateKeyRequest reads the data and then uses it - it doesn't keep a reference
- 15:53:45 [glenn]
- ok, thanks;
- 15:53:59 [Zakim]
- -mahesh
- 15:54:11 [glenn]
- be careful about mutability / liveness of session object
- 15:55:01 [jasonlewis]
- Topic: Requiring generateKeyRequest() in all cases for all key systems
- 15:55:13 [jasonlewis]
- Paul: Solved by previous discussion
- 15:55:21 [adrianba]
- q+ to ask another question on the object
- 15:56:09 [jasonlewis]
- Topic: Next Steps
- 15:56:40 [adrianba]
- q?
- 15:56:49 [jasonlewis]
- Paul: seems that we need a change proposal for items a, b, c from agenda and bring this to meeting by July 10
- 15:57:14 [jasonlewis]
- David: I will get this out today
- 15:57:23 [jasonlewis]
- Topic: Any other business
- 15:58:01 [jasonlewis]
- Adrian: is it possible to get from keySession object from mediaElement
- 15:58:17 [Martin]
- +1 to being able to get from key session object to media element
- 15:58:33 [Zakim]
- -Mark_Vickers
- 15:58:34 [jasonlewis]
- Adrian: if an event fires, how do you associate it with the mediaElement
