I can't help but feel the ffmpeg guys, despite providing a great service to the world, have got a real chip on their shoulder when it comes to all things Ogg and Xiph.

They don't like things that are badly designed. This same chip applies equally to a lot of other stuff, especially proprietary formats, like the utterly atrocious and buggy RealVideo 10.

Xiph gets a double dose, however, because of the methods that Xiph uses to market their bad technology. They have at times posted outright lies about their software and then, once proven wrong, often refuse to recant. Example: the Theora vs x264 PSNR comparison where they "accidentally" performed measurement wrong, making x264 appear 2x worse.

They use the same techniques as many of the more evil commercial companies out there, which annoys the hell out of people who disagree with such techniques. ffmpeg devs believe that open source should be about honesty and good technology, not lies and FUD. Xiph disagrees, believing that "the ends justify the means", creating a practically unbridgeable gulf.

Thus Xiph has spent the last few years spreading absurd amounts of FUD about everyone who they believe opposes them. They have managed to convince a shocking number of people that "ffmpeg is illegal" and that you should use their software instead. Ironically, almost all the FUD in the multimedia space in recent years has come from people who claim to support "free software"! Didn't we spend years criticizing Microsoft for the exact same thing?

And you wonder why people don't like them!




Wasn't that PSNR comparison problem because of an ffmpeg bug?

And what evidence have you that it wasn't done "accidentally" (your scare quotes). You're clearly wrong if you're implying they didn't retract that claim, as they do so here, in an update to the original page:

You seem to be, in this very post, doing exactly what you accuse them of, spreading FUD and lies about a competitor.

Maybe this feud goes way back, but you're not taking the moral high ground by calling them liars and cheats.


Wasn't that PSNR comparison problem because of an ffmpeg bug?

It was because of two bugs: an ffmpeg bug (signalling chroma positions wrong) and a bug in their testing tool (which resampled the image, something that a PSNR tester should never do for any reason).

You're clearly wrong if you're implying they didn't retract that claim, as they do so here, in an update to the original page:

Interesting, last time I looked they hadn't, but that's quite welcome then. But of course this pattern has repeated itself a dozen times already.
