Mozilla Donates $100K To the Ogg Project

LWATCDR writes "Mozilla has given the Wikimedia foundation $100,000 to fund Ogg development. The reason is simple: 'Open standards for audio and video are important because they can be used by anyone for any purpose without royalties, and can be inspected and improved by an open community. Today, video and audio on the web are dominated by proprietary technologies, most frequently patent-encumbered codecs wrapped into closed-source player widgets.' While Vorbis is a better standard than MP3, everything I have heard about Theora is that it is technically inferior to many other video codecs. I wonder if wouldn't be better to direct effort to Dirac, perhaps putting Dirac into an Ogg container. No mention was made of FLAC or Speex funding. If more media players supported Speex it would be an ideal codec for many podcasts and audio books. It really is too bad that these codecs so often get overlooked."

Ogg might be "better" than MP3 in terms of sound quality

First: <pedantic>Ogg is the container format, like QuickTime or AVI. Vorbis is the audio codec being compared to MP3. You could, if you wanted to, put MP3 bits into an Ogg container; I guess this would be "Ogg MP3". </pedantic>.

Vorbis gives you better quality per bit than MP3. That means you can have higher quality in the same number of bits, or similar quality in fewer bits. Given that most of us aren't using modems anymore, perhaps this is only a weak selling point for Vorbis. It's still nice for small portable music players, though.

but ultimately it consumes significantly more CPU time.

As I understand it, the overhead for Vorbis isn't really that bad. The chief sticking point is that the little portable players use DSP chips, and the DSP chip vendors have excellent support for MP3 and no support for Vorbis. This means that when a project like Rockbox adds Vorbis support to a portable player, often they use the main CPU instead of the DSP chip, and that means a drastically worse power drain.

A sticking point from the past was that Vorbis was written to use floating-point math in the decoder. The Vorbis folks made an integer-math-only decoder called Tremor, which answers that point.

For a desktop computer, you would never notice the difference between a good Vorbis decoder and a good MP3 decoder.

I think the main reason for the lack of Vorbis takeup is inertia. Everyone has MP3s, so the players all support MP3s. Since the players support MP3s, only geeks like me bother with Vorbis, so the player companies don't feel motivated to support anything but MP3. I used to hope for Vorbis support everywhere, but now MP3 is just a few years away from its patents expiring, so it's going to be MP3 for the near to middle term.

I own a couple of Sansa players that can play Ogg Vorbis. They have excellent battery life, despite being tiny little things. They stand as examples that there is no inherent technical reason why Vorbis cannot work on small portable players. By the way, if you are a geek, you should consider one of these before you buy an iPod Shuffle; more features for less money, and it works as a USB storage device so it works perfectly well on Linux.
