Parent article: GStreamer to support DRM

DRM support in free software is easy. Just write a bunch of code like:

if (event.key == BUTTON_FAST_FORWARD) {
/* Altering this clause of the if statement is a violation of US law. */
if (stream.permit_ff) {
do_fast_forward();
} else {
display_silly_dont_press_that_button_again_icon();
}
}

What law would that be?

I'd have difficulty seeing that work in a GPLed product.

Whichever law they're (ab)using now to prevent mass-market DVD players that can fast-forward through all video sections of the disc.

Actually that wasn't such a good example, since fast-forwarding is not copyright infringement--you only agree to not fast-forward when the disc tells you to in your implied acceptance of the DVD player's shrink-wrap license.

Suppose the example instead checked the resolution of the output port (as in the new analog hole bill) and refused to emit output without authenticating whatever's connected to said port. All software-based DRM systems boil down to basically the same code as in my example. The only difference between most of the systems in the field and a GPLed DRM-encumbered player is that you can grep the source code for the GPLed DRM-encumbered player and easily circumvent the restriction (although apparently sometimes this is illegal). Of course, such GPL code wouldn't survive very long without removing the restrictions, since users of GPL code don't really tolerate people trying to tell them what they can't do with their own machines.
