It is naive to expect that decrypted media stream will ever be leaving CDM module as so optimistically shown on that illustration.
Microsoft dropped and neglected a bunch of great features when shipping Vista, but it went out of its way to drag Protected Media Path into it. PMP is fronting a major industry effort to create trusted software and hardware framework that on one end accepts encrypted stream and on other draws video pixels on the screen, all the while showing a middle finger instead of raw data to the user on whose system this whole circus unfolds.
It will be laughable to think that CDM won't be PMP-based. Getting access to the raw data with CDM in picture is a pipe dream. Mozilla, sandbox, open source - no matter. CDM exists to prevent raw data leaks.
This concerns me. Amazon Prime Instant Video requires HDCP via Silverlight. Support for this is pretty much non-existent in Linux drivers, so watching Prime video via Pipelight is limited to standard definition (no HD).
I worry that with EME/CDM will come a requirement for HDCP on other services such as Netflix. Inconsistent HDCP implementation will be another thing to fight on the video driver compatibility front (and let's be honest, I don't give a crap about HDCP support - it's a flawed system that assumes every user is a pirate).
Edit: It's said to be a downloadable extra at user option.
The Moz page description of the sandbox says the CDM won't have any system access, so it could not distinguish whether PMP is there or not, except maybe by flags in the input from the browser. So either the Mozilla sandbox-CDM can't work as described or PMP won't be required.
Someone correct me if I've missed something there.
So were about to see Iceweasel fork a bit more from base firefox and add a button to render the "encrypted" content to file?
10/10 media industry, you guys are just the absolute best about sticking your fingers in your ears and singing lalala while substituting reality with your own where electrical charge isn't replicable.
