"Moreover, if it works on Firefox/Linux, how can they prevent someone grabbing the video from X and the audio from Alsa?" Well, that's exactly what they want to remove. HDMI for example forces all companies that use it to "respect intellectual property" removing the option of copying without errors. If the companies don't do it, the permission to use HDMI gets voided, so everybody has to do it. With Linux and Firefox they want to add firmware and special hardware so Linux could "manage the video" but not see it. For example an nvidia graphic card uses a firmware that is closed source, even with noveaou project. In their perfect world a Linux program could give orders like "draw this frame on the screen" without actually being able to access the frame. Of course the screen also has DRM. With new CPU processors DRM and secret firmwares even OSes are being installed in the chip. This DRM has total control of your machine including all memory peripherals and so on. They are actually making this DRM mandatory so they can spy on users and report "illegal practices" automatically. Microsoft is already sending home all your watching media metadata. Most video is also compressed so if you take single frames or audio buffers and compress it again you lose a lot of quality. That is because for example DCT blocks positions will change.

> This DRM has total control of your machine including all memory peripherals and so on. The foundational premise is false. You can build a machine that follows DRM, what you can't do is know if you're talking to that machine or some other machine controlled by pirates who extracted the keys from the that machine. Nor can you stop them from extracting the keys when they have physical control. But the futile attempts are certainly expensive for everyone. Though much less expensive for the pirates, who don't have to follow the rules and so don't suffer the consequences when they're inconsistent, inconvenient, unreasonable or bureaucratic.
