Google Chrome's Inclusion of FFMpeg Vs. the LGPL 245

Posted by timothy from the to-make-one's-head-spin dept.
An anonymous reader writes "Google has recently added FFMpeg to Chrome to better support HTML5's video element. FFMpeg is licensed under LGPL 2.1, which states that 'if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library.' Google admits to having obtained a patent license for their use, but still claims they are not violating LGPL. Among the confused we find Håkon Wium Lie and Miguel de Icaza, who wonders what FSF might say. Google doesn't feel like asking FSF for clarification."

    So, what you're telling us is that although all of us in the States have been using FFMpeg illegally without a license for years, when someone finally decides to try and be legal and purchase a license, now they are still in the wrong?

    Sounds like the FFMpeg people need to start dual-licensing or something - from what I can tell they are OK with people obtaining licenses to use FFMpeg.

    Of course, I'm still missing the biggest point here - since when do they need FFMpeg for HTML 5 support? It doesn't require any patented codecs, and they could always use DirectShow filters.

        The source code for FFmpeg is easily locatable in the same place as
        the rest of the Chromium source:

        The first email linked to in the summary pointed to chromium, which is why I linked to the terms page. I don't really know the difference between Chrome and Chromium, I just figured that Chrome was built on top of Chromium, or that Chromium is the site that holds the Chrome source repository. Anyway, I've been fighting back cold symptoms all day, so my ability to concentrate isn't what it usually is.

    • Chromium is not the same thing as Chrome.

  • From the attached article I can gather that since FFMpeg uses the LGPL 2.1 (not 3.0) that their obtaining a third party license for something else that prohibits them from granting similar rights for that bit of code does not affect their ability to grant rights for use the FFMpeg libraries. As they put it:

    The fact that Party B may have a patent license with an unrelated third-party is irrelevant as long as it doesn't prevent Party B from granting people the rights LGPL 2.1 requires they grant them (namely, only those rights it in fact received from Party A).

    Again this all seems rather moot anyway. A lot of operating systems these days include FFMpeg libraries as well as the H.264 and AAC libraries (which is really what this is all about). I know people feel like the idea of linking native libraries from the OS (which may or may not be there) goes against the universality of the HTML5 video/audio spec (and I can't say I disagree), but it would seem that for something as ubiquitous and freely licensable as the FFMpeg libraries, this argument is a bit overblown.

    I think Google's relying on a technicality, but it's a significant one. In this case Google isn't the creator of the library, they received it from it's creator. So either it's creator could grant them an LGPL 2.1-compatible patent license, or the library can be distributed without a license, or it's creator couldn't have legally distributed the library to them. I think that, right or wrong, Google's probably on solid legal ground there. They didn't introduce the patented code into the library, they didn't create the library, so I don't think the law'll have much trouble allowing them to redistribute the code under the same terms and with the same rights as they got from it's creator.

    I think it's a situation the GPL and LGPL don't contemplate explicitly. The situation where Google was adding the infringing code to a library they received under (L)GPL terms and then redistributing the results, that's exactly what the v2 language covers. But I'm not sure even the v3 language covers the situation where the holder of the patent license isn't the one who put the infringing code into the library and where the person who did put it in doesn't hold a patent license and has no rights to grant downstream recipients. If the library was under LGPL v3 I think you could make an argument that the automatic grant of rights in paragraph 11 kicks in, since Google does hold a relevant patent license, and that if their license doesn't let them do what paragraph 11 requires then they can't redistribute, but LGPL 2.1 doesn't contain anything explicit corresponding to v3's paragraph 11.

    I think Google's right here, it does in fact come down to what the patent-holder says. If they sue Google and get an order blocking Google from distributing infringing code, then Google can't distribute the library. If the patent holders sue the library's author and get an order blocking distribution of the library without a patent license, Google can't distribute the library. But until then, Google can't be forced to add any rights that they didn't get when they received the library.

    • Furthermore, the fact that there is at least a reasonable argument that Google is in the clear here ought to at very least relegate this to a contract issue. I, for one, think that reasonable contract disagreements should never impose copyright infringement penalties on the losing party. (see my most recent journal post for more on this.)

      You're confused. The author of the product doesn't have to abide by the license, they own the copyright and can do anything they want. The LGPL doesn't apply to them. It's perfectly legit for them to say, "hey, here is this code that implements patented algorithm X. if you want to use it you'll have to get your own license from the patent holder."

      As far as this goes with the ffmpeg authors violating the patent by implementing this stuff in the first place, there is a certain amount of protection from patent litigation if you are doing research. Not as safe as having a license, but better than selling a blue-ray player without one. Additionally these developers are probably pretty close to judgment proof (ie. they mostly have no money to pay any judgments against them.)

    The situation this clause of the LGPL is aimed at is one wherein Google would be obligated by their patent license to require that everyone they distributed the program to sign a patent sublicensing agreement that took away rights granted by the LGPL.
