Xvid is an MPEG-4 codec, right? "In theory" they should all be player-compatible. What's the patent situation with MPEG-4? Audio is another matter; are there freely available players for Windows, Unix, and MacOS that can play files encoded as your describe? -- brion vibber (brion @ pobox.com)

MPEG-4 is massively encumbered by patents owned by Fraunhofer IIS.

New subject: VP3 is a better video format ?

Yes it appears that XVID is MEPG-4. We don'care a lot with it in Europe but this a serious issue elsewhere. That's why I suggest VP3 as a better solution. Any advice ?

So far I've testted Xvid with silent video it works fine. MPEG-4 is standard but I had problem with the FourCC code in an avi file. MPEG-4 is an ISO standard but there seems to be some controversy about patents, who knows more ? With the Windows Media Player sound will work if you have the Xvid and the Ogg/Vorbis codecs installed With Linux it depend which player you use but the best one are now codec compatible with Windows With a Mac well I don't know.... Who can clarify the MPEG-4 patent issue ?

Having searched on the web it seems that MPEG-4 lpatent issues are problemetic. VP3 would be a better choice. see http://www.vp3.com

Does Wikipedia even want to consider hosting video until it gets its servers sorted out? Personally, I think that any high-bandwidth material should be served from a (third) machine independent of the (not yet implemented) web and database servers. -- Using M2, Opera's revolutionary e-mail client: http://www.opera.com/m2/

Bandwidth isn't our problem, though of course it would be nice to have a separate media server too. Serving large static files is fairly easy to do. -- brion vibber (brion @ pobox.com)

But I thought available connections were. And media files will keep a connection tied up for a while. And the act of taking chunks of a file, packetizing them and pushing them out to the network still consumes some CPU, doesn't it? -- Using M2, Opera's revolutionary e-mail client: http://www.opera.com/m2/

Sure, some. But as long as we're hosting 750 megabyte backup dumps on the main server, I don't think a few several-megabyte videos are going to be a real big drop in the bucket. -- brion vibber (brion @ pobox.com)

Forgive my naiveness, but what is a backup dump?

Wow! all of wikipedia (and everything else related) is only 235 mb? Somehow I assumed it was more than that

When heavily compressed, and not including old revisions, images, and runtime helper information (link tables, recentchanges, etc), then yes. :) Including old revisions it comes to nearly a gigabyte compressed. Tossing in the uploaded images & media files would add another gig or so if I recall. Hmm, which reminds me, I should set up a mechanism for backing up the images more regularly. -- brion vibber (brion @ pobox.com)
