VideoLAN Announces libaacs

supersloshy writes "VideoLAN, makers of the well-known media player VLC, have just announced a new project called libaacs. The libaacs library's intention is to provide a free software library to implement the AACS specification, the copy-protection found on things such as Blu-ray discs. Note that this isn't meant to actually be a decoding library. It includes no AACS keys and is solely developed for research purposes."

One small error

[supersloshy]

Sorry guys. I submitted this article before I realized this. libaacs has been around for a while and was a project started at Doom9. It was just adopted by VideoLAN. My bad!

Sounds legit

Riiiiight

Without the keys, it's 1201(g)

[tepples]

I'd like to see how such a cease-and-desist notice might be worded. From the summary: "It includes no AACS keys". From the article: "this project doesn't offer any key or certificate that could be used to decode encrypted copyrighted material." So without the player keys, it's not a complete circumvention device but instead an encryption research project, exempt under 17 USC 1201(g). And even if it did have keys, the interoperability exemption in 1201(f) combined with the fair use exemption that the Register of Copyrights recently enacted for three years might save it.

Fuck you, pipsqueak? ;)

Re:Cease and Desist in

If they had the power to take down BluRay decrypters, they'd be going after the commercial tools that actually work. This is roughly the umpteenth open source library announced and what they all have in common is that they don't work on any of the newer movies with MKBv11 or higher and/or anything more than the simplest forms of BD+ protection. It's unlikely open source will catch up until the MPAA gives up the DRM fight, you may not see it but there's still a constant war of updates to make the decrypters work on new discs.

Which "intellectual property"?

[tepples]

You seem to be under the impression that having the law on your side means that you won't be harassed by lawyers.

This is the sort of thing that EFF jumps all over.

The cease-and-desist will claim some intellectual property violation

One does not violate "intellectual property". One infringes a copyright, infringes a patent, or infringes a trademark. Which of the three would apply?

[PopeRatzo]

This is the sort of thing that EFF jumps all over.

And the EFF has some bad-ass lawyers. I know one EFF lawyer, who spoke to a local group here in Chicago back in the Spring, who's been offered jobs by two industry groups. I guess they figured they'd rather be paying him a salary than facing him in court. He was an interesting guy. He'd made some dough doing mergers or something before joining the EFF and didn't seem to be phased by the dangling carrot. He was also an extremely persuasive speaker. I could understand why someone like the RIAA wouldn't want to meet him in front of a judge.

Translation of research exception in the law

[ciaran_o_riordan]

From the cited ruling which discusses application of the EU ban on circumventing DRM:

Ces dispositions ne s'appliquent pas aux actes qui ne portent pas préjudice aux titulaires de droits et qui sont réalisés à des fins de sécurité informatique ou à des fins de recherche scientifique en cryptographie

Which roughly translates to:

These provisions do not apply to acts which do not interfere with rights-holders or to acts carried out for computer security purposes or for scientific research or cryptographic purposes.

So libaacs is legally 100% safe so long as it stays in those boundaries. (That EU law is unjust and should be contested.)

"legally play a Bluray"

[GodWasAnAlien]

"legally play a Blueray" (same question for DVD)

What exactly does that mean?

A Blueray/DVD player that one may purchase at Best Buy also decrypts the disc. Is that circumvention also?

What exactly is the difference between a commercial player and an open source player (which also must decrypt the disc)?

The main difference that I see is that one is using the official specification, and one is using an unofficial specification.

But using an unofficial specification is not illegal.

Perhaps, If some are claiming that an open source player plays "BlueRay" or "DVD" discs, then that may be a Trademark violation, as it has not been certified.

Is that what you are implying? a Trademark violation?

Re:"legally play a Bluray"

[TheGratefulNet]

no, you miss the point.

players are LICENSED. money.

freeware players skip this. that annoys those who, uhh, like money.

get it?

its JUST that simple.

(then again, you can't GET a license just by asking for it. you have to bend over and kiss corporate ass and promise never to allow users to do what they wish with the media they bought)

back in the early days of linux/dvd, authors DID try to buy 'proper' licenses. they were refused. at that point, we all turned 'rogue' in the industries' eyes.

well, so be it. don't want our 'player fees'? then you get NOTHING.

but we still will be able to play our media. you have done nothing but stopped revenue to your own self, you silly mpaa morons.
