As HTML WG co-chair I want to reinforce the point that asking for product specification documentation on a W3C email list is not appropriate.

You have told this before, so please desist in making this kind of request.

This is not an appropriate venue for this request.

If you want Widevine documentation, I suggest you reach out to Widevine directly, as David Dorwin already told you, the day after you asked your question.

The W3C does not have Widevine documentation.

It has now been a month since my request for documentation/software on how to encode video for chromebooks compatible with chromebooks DRM. None has been produced.

Widevines proprietary DRM solution is suggested to achieve DRMed video hosting. Widevine is not offering libraries/documentation to the public to use. This will not keep most people from using flash/silverlight to implement their own solution. I do not see any improvement by this over the status quo. EME proponents are still without an answer and a resolution to this simple question: How do I encode and host DRMed content.

This issue is not addressed.

I addressed this issue in https://www.w3.org/Bugs/Public/show_bug.cgi?id=20967#c11, which you replied to. Container and encryption details can be found at https://dvcs.w3.org/hg/html-media/raw-file/tip/encrypted-media/encrypted-media.html#containers, and there are no special hosting requirements. You can try it out with the Clear Key ("webkit-org.w3.clearkey"), which is available on Chrome and Chrome OS. If you are interested in providing licenses to the Widevine CDM, I suggest contacting Widevine: http://www.widevine.com/contact.html.

As a reminder, no answer has been provided how I could encode and host DRMed video for the Netflix/Google Chromebook DRM since a week now.

I expect that David can answer your questions about Google's implementation.

Subject: Chromebook DRM specification

Apparently Google Chromebook now supports "HTML DRM" and Netflix has started serving content that way (source: http://news.slashdot.org/story/13/03/11/2155219/netflix-using-html5-video-for-arm-chromebook)

Could anybody point out the specification and required libraries that'd allow me (or anybody) to encode/host their videos compatible with chromebooks html DRM implementation?
