question about ogg/ogv

[laurent.bellegarde]

Hi everyone,

where can i found informations about the rules to create free video using

- video : theora

- audio : vorbis

- container : ogg or ogv

as i look there, the official website doesn't indicate ogv container ???

http://www.xiph.org/ogg/

Is there something official for ogv, because none of all the video 
editing software under GNU/Linux is creating ogv container, only ogg.

Thank's for your answers,

Laurent
