Mpeg 4 is an open video standard.

DivX, Xvid, Theora, etc...

Ogg Theora. Any other format is patent encumbered.

Technically, so is Theora since it's based on VP3, while fully GPL'd just like Xvid it's still based on patented technology.

In the future, it may end up being Dirac:

The BBC have taken out defensive patents, but claim they won't use them to stop Free implementations. However, based on the Doom9 comparison of this year, Dirac is still a long, long way from being ready for primetime - if it's ever ready at all :(

OGM is a (nice) containerformat.

My OS videocodec of choise is Xvid, it performs best.

Ogg is just the wrapper.

Theora and Vorbis are the best combo. Try VLC if you want a graphical user interface to rip to these formats.

www.xiph.org for more info on the goals of Theora and Vorbis.

You mean Vorbis..

You completely misunderstand the concept of a container format.

The Container format for Vorbis, Theora and the new Dirac derived format is Ogg.

As for what is the video format of preference, currently Ogg Theora is the only non-patent encumbered format which is somewhat ready for primetime, A Dirac derivative will hopefully replace it within say a years time.

And to the person who claimed that MPEG4 is an open standard, it is not open in the sense that it signs over patents, thus use of any derived format is in violation of the patent license. XViD as nice as it is is not a free format, but at least you get the source.

So where's the linux codec? I downloaded a movie in 264 and I have to use Windows to watch it. I can't even burn it to DVD since the only program I found would only view it.

d9 says it is the best.It is good. That movie is really sharp, and not a huge file. Less than 1GB.

Xvid.

All the videos I have ever downloaded were ether Xvid, WMV, or KVCD (which I think is mpeg). The two latter as far as I know are not open source.

Ogg (i.e. Theora video stream, Vorbis audio and Ogg container) is currently the most open video standard. Dirac is simply a video codec at present - and an immature one at that.

Video codecs such as XviD and x264 are components of the MPEG-4 international standard (Part 2 and Part 10 respectively). MPEG-4 isn't as open as Ogg but its advantages are much wider hardware support and superior quality video.
