There is an example of an Ogg Theora/Vorbis video on EngageMedia you can look at here.

Foundation as part of their Ogg project (It is a project that aims to
integrate On2’s VP3
video codec, Ogg Vorbis audio codec
and Ogg multimedia container formats into a multimedia solution that can
compete with MPEG-4 format).
Theora is derived directly
from On2’s VP3 codec; currently the two are nearly identical, varying
only in framing headers, but Theora will diverge and improve from
the main VP3 development lineage as time progresses.

Theora is a video codec. Ogg is the transport layer that both are stored in,
so a video file will be Theora-encoded data inside an Ogg file, while audio
is normally Vorbis-encoded data inside an ogg file.

Recommended Ogg Transcoders
Here is a list of software you can use to create Ogg Theora/Vorbis files on your computer:
We recommend the use of these applications to create Ogg files on these platforms:
All these applications are still in development, so you can expect a bug here or there, but are very simple and easy to use.
