Well, if posting binaries (without paying royalties) is illegal and you post a link to a site with binaries, then it's a link to a site with illegal content and I don't think this would be acceptable...

Yes I have to agree to that
This would then make my program illegal, because it would depend on DLL's that are freely available, but the "whole" is then illegal, if I don't pay royalties to MPEGLA.
I don't think we'll see the KVCD encoder working with MPEG-2 avcodec libraries. It will just be MPEG-1, until I contact MPEGLA directly for further clarifications.

But you know if site with binaries didn't pay licenses?
Kwag's encoder also can leave this door open.
What users do with that is not a developper problem.

Even if I know that what I say is not mutch apreciated, i (as always) think that a FairUse-like approach (direct DVD encoding) would be great.

What do you mean patchworks?
What is it you say that we don't appreciate in what you say?

What do you mean? That we don't appreciate a good fellow like you bumping in on a thread and posting completely out of the context?
Or do you mean that KVCD Encoder GUI should be similar to Fairuse?
Cheers

Hello to everyone ! I was navigating in ffmpeg home page and there we have a faq about licenses issues:

Quote:
ffmpeg License
ffmpeg is licensed under the GNU Lesser General Public License, or LGPL. Essentially, this means that you are allowed to use the ffmpeg library in your own application, regardless of your application's license. However, if you alter the ffmpeg library in any way, and subsequently distribute it, you are expected to make those changes available under the LGPL license. This is the full text of the LGPL.

Be advised that ffmpeg incorporates several modules that are covered under The GNU General Public License, notably liba52 and libpostproc. If you use these components in your project, you are expected to release your whole application under the GPL if you distribute your project at all. This is the full text of the GPL.

Trademark
ffmpeg is a trademark of Fabrice Bellard, originator of the ffmpeg project.

Legal Mini-FAQ
A lot of legal questions arise when discussing multimedia technology. This mini-FAQ attempts to address these issues. Note that much of this discussion is based on precedent, or what has happened in the past under similar circumstances. Very little consideration is given to what could happen. If you use your imagination, you can visualize any dire scenario and cease doing any productive work.

Q: Does ffmpeg use proprietary/patented intellectual property?
A: Yes. There is a lot of multimedia available in proprietary/patented formats so it becomes necessary to support such formats and even reverse engineer them where required.

Q: Is it legal to use such proprietary/patented IP?
A: IP laws change wildly between jurisdictions. Further, even in places where software IP is recognized, there is serious doubt about the legitimacy of such legislation.

Q: Bottom line: Should I be worried about legal issues if I use ffmpeg?
A: Are you a private user working with ffmpeg for your own personal purposes? If so, there is remarkably little reason to be concered. Are you using ffmpeg in a commercial software product? Read on to the next question...

Q: Since ffmpeg is licensed under the LGPL, is it perfectly all right to incorporate the whole ffmpeg core into my own commercial product?
A: You might have a problem here. Sure the LGPL allows you to incorporate the code. However, there have been cases where companies have used ffmpeg in their projects, usually for such capabilities as superior MPEG-4 decoding. These companies found out that once you start trying to make money from certain technologies, the alleged owners of the technologies will come after their dues. Most notably, MPEG-LA (licensing authority) is vigilant and diligent about collecting for MPEG-related technologies.

Q: I am still terrified of the legal issues; should I still use ffmpeg?
A: ffmpeg has a special mode just for use which disables compilations of all of the legally-questionable components. Not surprisingly, when compiled in this special mode FFmpeg does not do much.
Cheers,

If you live in a country where software patents are not recognised, you can distribute the binaries legally AFAIK. Unfortunately patent laws exist in the US. I live in Australia, and we don't have software patents, yet. The Fair Trade agreement with the US is going to change this, which is going to screw small business in here. Until then, AFAIK, I can distribute binaries and legally as far as Australian law enforcement is concerned. But correct me if I am wrong.

So Kwag, if you would distribute it outside the US, would it then be legal (or if you ask someone in a country where no Software IP laws exists to do it)??

Thanks Peter.
But I think I would be screwed, because I'm in the US (Puerto Rico), so even if I distribute the binaries on some remote site, the source of origin is still US, and there are legal bindings to that too.

An off (but close) topic: Last night I read an interesting article about the site "SUPRNOVA.ORG" about to be shutdown by authorities: http://www.slyck.com/news.php?story=602
I guess most of you know what it is. Remembering the site "ShareReactor", which was shut down, and they only posted links to copyrighted stuff, suprnova.org will be shut down for shure, because on top of having links to warez stuff, they even "host" the .torrent files.
So the ramifications are very strong for a site shutdown.
This is just an example of the things that are going on on the net. So even if I distribute the files on a "off shore" site, I'm sure they'll try to find a way to make the connection. I'm still evaluating other legal possibilities.

Thanks,
-kwag

True, this gets sometime sick.
I've readed on my local portal (that takes a goal, to point some people using illegal software, that there exsists freeware or cheeper possibilities) that in US some organisation proceded small test. They sended emails to providers hosting some sites, with abuse information about illegal contents of some sites. Mails were from popular mail serveices like yahoo or lycos, and 8 of 10 providers shut down pointed sites without even bothering if content of site is illegal Sick
So this is risky.

What if illegal material is hosted on Chinese or North Korean (or Russian) servers. US companies don't even bother with copyrighted material on Chinese servers, the Chinese government doesn't care (and probably love the fact that it pisses off US companies). And the US doesn't want to cause any conflicts .

Well, that's true, but mostly because the US doesn't know the source of origin. They are hosted anonymously by anonymous posters.
But in the case of the KVCD encoder, I'm sure if I host it on the moon, they'll come after me

Hi Kwag an others,
all this legal staff complicate things a lot . Let me see if I understood well: as libavcodec is able to encode mpeg streams, any encoder based in libavcodec should pay royalties?, did I understand it well?. If not, K-encoder could be released with MPEG-2 abilities just linked to libavcodec, and as Kwag said, a Pro version with charged codecs. Am I saying silly things?.
Anyway, I'm willing to test it even with MPEG-1 support "only". I'm sure it'll look great . And then you'll find the way to make it able to encode KDVD. Sure.
....
...
..
.
waiting with excitement

To dumb down US law as far as that goes, the data on the computer is under the jurisdiction of the country in which the computer is physically located.

If you had it hosted in a country where they dont care about copyright laws, or never signed the bourne convention (south korea comes to mind), you would be in the green, but the people who downloaded it would not be.

1) What about distributing the sources (of the codec only) along with a makefile and detailed instructions on how to build it with some specific free compiler (like gcc, bcc)? Would that be OK?

2) If you write the mpeg-2 encoder in java (interpreted) would that be considered "source code" or "binary"?

Java is not interpreted but pre-compiled in a pseudo language that will be understood locally on any client by the VM.

JavaScript is interpreted. And if you manage to do a mpeg2 encoder with this, tell me

Interesting. Its more likely to be possible to write it in a VB Script. Assuming it were possible, who would be patient enough to encode at ~1fps or less? Maybe in the future when we all have 50GHz machines.

Exactly I wouldn't

At that time, a JAVA encoder would do real time encoding, and a C/C++ (or other optimized compiled language) will be doing 50X realtime

What is it you say that we don't appreciate in what you say?
I mean that no one (both here and @ FairUse forum) seems interested to build a DVD-to-K(s)VCD backup tool (like FairUse, that is a DVD-to-MPEG4).
Can't understand why... I think that an open source backup tool that can (also ?) encode *directly* from a DVD could be interesting for DVD-players manufacturers to bundle with... and probably they can support its develop.

Probably I have misunderstood the open source philosophy, but I always try to express my opinion about a project, expecially if is constructive.

Anyway, happy coding !

Sorry patchworks,
I still don't think I clearly understand what you are trying to say.
There's no problem in showing your emotions towards any project around .
But the truth is, this is not an "open source" forum.
Meaning, most of us like to use open source tools but most of us think that plain freeware does the trick and that there's no need for the source if the coder is interested in keeping it for himself.
Of course as long as he maintains it's code.
Cheers
