Well, that was zapped pretty quickly by the powers that be. Here's a theory...
On2 must be pretty scared of their codecs' source escaping into the wild because the source could be used to prove patent infringement. Without the source, patent holders like AT&T and Microsoft can only guess that VP6 might tread on their IP. Having looked at the source, it's interesting that, for a proprietary, independent codec, VP6 shares so many tools with MPEG-4 pt2 and pt10 (H.264). I'll stop now, I'm being mischevious... Edit: Naturally I'm not alleging intentional patent infringement on On2's part - my point is that even the most upstanding public company will find it incredibly difficult to create a video codec without treading on multiple patents. By keeping the algorithm closed, companies can ensure they do not place potentially incriminating evidence (source code) in the hands of the "prosecution" (patent holders).

i guess on2 contacted sourceforge and this hosting company to remove the code. this either means:
1) the source was leaked and therefore on2's copyright was violated 2) on2 doesnt like their format to be publically known (which in fact now is the case no matter if the code gets removed from sf) now regarding 2) i wonder whether reverse engineering is illegal? or whether offering code that uses someone elses patents is illegal without having the approval from the patent holder (same case as libdts)

So if you hadn't asked, then maybe they never would have noticed? Although presumably whoever got Siber's files deleted read this thread.
If I were On2 and I had gotten the project removed, etc. then I wouldn't discuss it either if I didn't have to. |

On2 Position
We have previously and continue to be supporters of the open source community and have made significant contributions to open source video technology. As a public company, however, we feel that it is important to protect our intellectual property from abuse and to take all steps necessary to protect that property.
We therefore cannot support the unauthorized release of code that we believe has been illegally obtained or obtained in contravention of our licensing terms. We respect the hard work of the open source community and honor that work by observing contributors' copyrights and chosen licensing terms. In return, we expect the community to show the same respect to our works. On2Tech |

Just a little question/criticism - I asked On2 about legality of this code multiple times and does not get any response too long... Why?

Response to Dimzon and Wilbert
Dimzon,
I am sorry that we have taken so long to respond. In our defense, we felt that it was important to study the code first. Also, we have to be careful about making off the cuff statements in forums, without observing due process. Wilbert, Sorry about that, we have been busy getting the new VP7 release ready amongst other things !! That said, we should at least have responded to your PM. A bit of a communications breakdown at our end I’m affraid. I will try and chase it up and get back to you ASAP. On2Tech |
