And the definitions of "product chain", "end product", "end product supplier" and "End User" would probably need investigating before anyone thinks that Google has now licensed the patents from the cartel for everyone. Just to preempt any jubilation that H.264 is now "safe" for genuinely open standards, of course.

I replied, with questions for clarification:
==========MY REPLY==========
Allen,

Thank you for the information. I think I grok, but I do have two
questions:

From Allen Harkness on Thursday, 28 January, 2010:
>In response to your specific question, under the Licenses royalties are
>paid on all MPEG-4 Visual/AVC products of like functionality, and the
>Licenses do not make any distinction for products offered for free
>(whether open source or otherwise). But, I do note that the Licenses
>addresses this issue by including annual minimum thresholds below which

What are these thresholds? Ideally, I'd like numbers, but information
on whether it's monetary or downloads is more than I have now.

>maximum annual royalty caps to provide more cost predictability for
>larger volume users.

How does this work in an open source or Free software setup, where
the source code is modifiable and re-distributable? Are downloads
from the licensee only covered?

Two scenarios come to mind:
1) A corporation has a customized (i.e. modified) build of Google's
Chrome (which includes an implmentation of ffmpeg), and then
re-distributes this modified binary to all of the workstations at
the company. Is this covered by Google's license?

2) A corporation downloads one copy of Chrome from Google, and redistributes
these internally to its workstations. Is this covered by Google's license?

3) Same scenarios as above, but for a home user distributing to others.

Thanks!

-Joseph
==========END REPLY==========

I've not received an answer to date. I'll post if they respond back.

Also, I'd like to take this moment to thank Fluendo for providing a licensed method. I hate software patents, particularly for what are otherwise open standards. Maybe we need patentleft to kick things off? It is, after all, another license in the end.

Finally, I'll also go ahead and say that all my videos that I have control over are Theora. :)

A company is thanked for providing proprietary software. This must be a precedent on lwn.net. Anyway, you could have said that you don't care about free software right at the start. That would have saved us going back and forth about the finer points.

Given his earlier actions in poking MPEG LA with a stick, apparently in
the hope they'd wake up and say 'ffmpeg? what's that? stop, now!', I think
his not caring about free software goes without saying. Or, rather, given
a choice between free software and his being right, his being right would
come first every time.

(apologies for sexist phrasing, but this particular odious characteristic
is in my experience restricted to males. Generally young ones.)

It wasn't poking with a stick, your assumptions about my motivation are completely off the mark, and your conclusion based on the above is also completely wrong. Fortunately, I don't have to prove myself to random jerks on the Internet.

"Or, rather, given a choice between free software and his being right, his being right would come first every time."

Also incorrect. Not surprising. I think your own prejudices color your perceptions here.

Well, what was I supposed to think? If your supposition that ffmpeg had
been ignored by the MPEG LA because they were beneath their notice had
proven correct, your own actions would have done nothing less than bring
another patent attack on free software. Well done.

All I did was ask for clarification on their FAQ. At worst, I hastened the inevitable by some unknowable quantity. At best, my email has helped show better where the licensing necessities are.

ugh. my thinking with a screaming baby ain't the clearest. at best would have been a fairytale ending of "GPL implementation is OK with us!" at worst i've improved our (or just my) knowledge of the licensing situation at the cost of *perhaps* hastening the inevitable by some unknowable quantity.

Screaming baby explains everything, I think. Rationality is not expected
under those circumstances. (Sanity is hard enough to maintain.)

So you're a fan of security through obscurity nix? I'm surprised.

I don't see a downside to getting everything into the open. It might mean some short term difficulty for the ffmpeg project (difficulty that I'm sure they're expecting anyway), but it means long-term stability for everybody.

Nice work Trelane. You're doing this for all of us. Thanks!

It still wasn't my intent to get anyone in trouble. Let's be clear on that point. I was solely looking for information (and if they'd said "Oh, we never thought of that! GPL is a great license, and you totally can consider yourselves covered!" or something like that, that'd've been great. As it is, we now know a bit more about implementations they don't care about making pay (see the thresholds I asked to be clarified.) And we have it in writing (as much as email is; I do have logs too))

It's also the start of a dialog, if they choose to go there. I'd be willing to talk with them about Free Software and patents and direct them at more knowledgeable people. Let's try to keep this positive!

For some reason people keep expecting trouble for us and expecting that we expect trouble. We have had zero trouble in the 10 odd years of our existence and are firmly convinced that we will see the same amount of trouble in the next decade. See also

The law and security have the same relationship to each other as theology
has to religion: that is, none to speak of.

Quit worrying about FFmpeg keeping a low profile. We're not a secret to any of the players in the industry and not to the MPEG LA.

Posted Feb 1, 2010 0:52 UTC (Mon) by nix (subscriber, #2304) [Link]

Oh I'm not worrying. I entirely believe you: ffmpeg is too influential for
MPEG LA not to know about it. But *if* the supposition (bandied about by
several here including IIRC Trelane) were true that ffmpeg had been
ignored because it was too ignorable or not a revenue generator or
something, then Trelane had just poked a dragon (or at least a troll) with
a stick. This is generally considered a bad idea, even if it turns out
that the dragon knows who you are and doesn't want to eat you today.

Personally, my guess would be that ffmpeg may be too influential. Banning
ffmpeg for patent-reasons would be pretty much poking not the bear, but the
bee-hive of pissed of techno-geeks everywhere.

As the mail states, there are intentional exceptions for low-volume (in
business speak, roughly the same as low-income) "in order to encourage
adoption". I would assume that for peace:s sake, MPEG LA is avoiding
confrontation to much provide the patent opposition with too much fuel for
their fire, and further de-rail wide-spread adoption.

Thanks for the compliment, but I will have to insist:

If you thank Fluendo for providing you with "legally licensed" proprietary software, then you should build a throne for Google, which is providing you with "legally licensed" free software, don't you think?

Do you also thank Adobe for "legally licensed" Flash and Microsoft for "legally licensed" Windows 7? They all come with an MPEG LA license..

If they work for Linux, providing a Free stack for multimedia and multimedia streaming and DVR functionality, then yes. Yes, I do. Your "throne" exaggeration is a bit extreme, though. I thank Google for their work on Chrome, although whether their patent license extends to you if you build Chrome and ffmpeg is murky at best (see also Fluendo and their MP3 plugin proprietary vs BSD-licensed). That's why I asked MPEG-LA for more information.

I also buy Codeweavers Crossover Office because they help Wine to a great degree.

"Do you also thank Adobe for "legally licensed" Flash"

I thank them for having a Linux plugin. I don't like Flash over Free, patent-free standards, though. (See also the "I produce Theora content") I'm doing my part to keep us viable now (Fluendo and their plugin work) and in the future (Fluendo's Free software, Theora/Xiph, and my FSF membership).

and Microsoft for "legally licensed" Windows 7?"

If I ran Windows, I'd thank them for licensing the codec.

You do nobody any favors when your patent protection plan is the equivalent of burying your head in the sand, putting your fingers in your ears and saying "There ain't no patent threat" three times fast. You counter it by helping establish Free, patent-free standards and filling the gap until we get to that point.

Fluendo is not a free software company. They stopped significant contributions to gstreamer years ago. They are a common and garden-variety proprietary software shop now. Why you would thank them for offering products for sale to you is beyond me, but hey...

"Fluendo is not a free software company. They stopped significant contributions to gstreamer years ago. They are a common and garden-variety proprietary software shop now."

From poking around in wikipedia and talking to GStreamer people, this isn't entirely accurate, although it's not entirely inaccurate either. My information was apparently out of date.

"Why you would thank them for offering products for sale to you is beyond me, but hey..."

Had you stopped prior to this sentence, this would have been a helpful and informative post. This sentence took that work and overshadowed it by jerkishness.

I got the information from Edward Hervey who works on gstreamer (and for Collabora, the company that funds gstreamer development nowadays) and hangs around in the #ffmpeg-devel IRC channel. Just look at the gstreamer commit graph of thomasvs, who works for Fluendo and commented in this discussion before:

You're not exactly a role model either, but the remark was dead serious. I never felt like thanking a supermarket for offering me goods for sale. Why would you thank any company for offering you their goods?

I got my information from several sources on #gstreamer and #fluendo. (note also that their gstreamer contributions are only a portion of what they do, s.a. flumotion, their streaming and recording several FOSS events, etc.)

"Why would you thank any company for offering you their goods?"

If it was the only place or one of the few places to get it legally, I'd be pretty grateful for it. Perhaps that's what you're not comprehending. Maybe we're just different people and see things differently, eh?

Fluendo vs. FFmpeg

Your continuous claim that FFmpeg is illegal is insulting. Your lack of appreciation for software freedom is sad.
