Well, WME currently only supports PCM encoded sound anyway...
That's why I suggested those two containers (matroska and ogg) so that we can have videos with the audio part encoded with the vorbis codec.
I hope Theora will fulfil our need for easy to use, patent free video format.
Yeah, I am waiting for the theora codec too. But as far as I know it won't be patent-free as vorbis and speex. It will just be opensource under the bsd-like licence xiph.org uses. But it will be covered under the same patents that cover all the mpeg4-like codecs. Please, anyone, correct me if I am wrong into this.
EDIT: Ok... I checked the licence thing. From the faq in
www.theora.orgQ: Isn't vp3 a patented technology? (theora is based on vp3)
A: Yes, some portions of the vp3 codec are covered by patents. However, the Xiph.org Foundation has negotiated an irrevocable free license to the vp3 codec for any purpose imaginable on behalf of the public. It is legal to use vp3 in any way you see fit (unless, of course, you're doing something illegal with it in your particular jurisdiction). You are free to download vp3, use it free of charge, implement it in a for-sale product, implement it in a free product, make changes to the source and distribute those changes, or print the source code out and wallpaper your spare room with it.
Q: What is the license for Theora?
A: Theora (and all associated technologies released by the Xiph.org Foundation) is released to the public via a BSD-style license. It is completely free for commercial or noncommercial use. That means that commercial developers may independently write Theora software which is compatible with the specification for no charge and without restrictions of any kind.
