- Thanks. The "or use the crossorigin…" bit at https://dvcs.w3.org/hg/html-media/rev/69dbfb8baca8#l1.19 is confused, though. A CORS-enabled fetch labels the obtained resource as CORS-same-origin or CORS-cross-origin, so using the crossorigin attribute is part of making a cross-origin resource CORS-same-origin. I suggest replacing " or use the crossorigin attribute on the media element and CORS headers on the media data response to authorize cros[CUT]

- joesteele: in the implementation we are working on, we are able to count all the references, so we don't get an orphaned session
- 15:32:36 [johnsim]
- adrianba: not so much orphaned, since there still is a reference, say you have two sessions sharing a key, you need to fire a keymessage
- 15:33:11 [johnsim]
- ... we agreed you only need to fire one keymessage, if you do that, you keep around the other session, do they all move into pending
- 15:33:34 [johnsim]
- ... originally you had two needkey events, so you create two sessions at the same time, but after the first cycle of getting ready
- 15:34:40 [joesteele]
- johnsim: need to document the use cases we are describing - hard to handle the otherwise
- 15:35:24 [johnsim]
- joesteele: where should that documentation take place? In the bug? Use case as a template?
- 15:37:23 [johnsim]
- adrianba: start an email or in the bug and go from there so we can make good progress before November

- ddorwin: last week discussion about pssh and interop
- 15:39:09 [johnsim]
- ddorwin: anyone could use format for pssh and system id
- 15:39:34 [johnsim]
- ddorwin: do we want to only support CENC or other proteciton systems.

- joesteele: we are saying we would send less information. part of the proposal to not include the sinf box?
- 15:40:30 [johnsim]
- ddorwin: current is to include the sinf box for other protection systems.
- 15:40:41 [joesteele]
- ack johnsim
- 15:41:14 [joesteele]
- johnsim: this was discussed in Leone - I took an action item to meet Dave Singer as he had an objection to passing just SINF boxes in the init data
- 15:41:24 [joesteele]
- ... he said what he thought should be passed
- 15:41:36 [joesteele]
- ... for full generality -- we modified the spec with his input
- 15:41:48 [joesteele]
- ... additional modifications came later
- 15:42:00 [joesteele]
- ... but there are consequences for these changes that make it complicated
- 15:42:13 [joesteele]
- ... if we were to only suppor the CENC it becomes less complicated
- 15:42:23 [joesteele]
- ... PSSH would not need to be passed (we think)
- 15:42:47 [joesteele]
- ... formatting of the PSSH payload is a separate question - going beyond W3C since those are proprietary
- 15:43:03 [joesteele]
- ... that is where we landed as of last discussion
- 15:43:15 [joesteele]
- ... everyone seems to be using CENC
- 15:43:38 [joesteele]
- ... all the changes we put in were proposed by Apple (Dave Singer)
- 15:44:20 [joesteele]
- ... we have some bifurcation in the spec already, could separate out the CENC and have it very well documented
- 15:44:31 [joesteele]
- ... what do the editors think?

- 15:47:19 [joesteele]
- johnsim: would like to get resolution on this soon
- 15:47:32 [joesteele]
- ... if there are objections we need to know what they are
- 15:48:12 [johnsim]
- joesteele: not publishing a heartbeat next week, give ourselves a week to talk about it. get a resolution before the heartbeat spec?
- 15:48:30 [johnsim]
- ddorwin: still alot of issues beyond choosing common encryption.
- 15:48:56 [johnsim]
- ddorwin: more stuff to fix beyond - long list of concerns
- 15:49:57 [johnsim]
- ddorwin: we could simplify by first four bytes are 'cenc' or indicate in the mime type it is common encryption in order to support other protection types

- ack markw_
- 15:52:38 [johnsim]
- markw_: any format for EME - use common encryption - that is - i think saying with common encryption on title is fine, but then if they came with a different format, then we would ask about the impact on interoperability
- 15:53:16 [adrianba]
- q+
- 15:54:19 [johnsim]
- adrianba: make the proposal, highlight the discussion to those who suggested we make the change in the first place
- 15:54:50 [markw_]
- q+
- 15:54:57 [johnsim]
- adrianba: a little uncomfortable not having a way to support other protection systems. maybe do as David suggested to signal common encryption

- ack adrianba
- 15:55:06 [joesteele]
- ack markw_
- 15:55:48 [johnsim]
- markw_: we say anyway that the initdata is a sequence of iso boxes, and in our common encryption it will be pssh boxes, if someone comes up with a different format they would define a different set of ISO boxes
- 15:56:11 [johnsim]
- joesteele: my comments - i agree - we want to say "common encryption", and agree with David proposal that we be flexible
- 15:56:38 [johnsim]
- ... main concern to deciding this is that D Singer is not on this call, and do some research on what exactly would have to be passed
- 15:57:10 [johnsim]
- ... i need to verify if the Adobe solution will work with only pssh - but standardizing on common encryption is a good thing

- 15:58:21 [johnsim]
- adrianba: send a mail to the list and cc them (David Singer, etc.)
