Ogg is the container, Theora is the codec. Theora is derived from the VP3 codec originally created by On2.

Ogg is a deeply flawed container format, for details see

Very interesting thanks!

So perhaps replace Ogg with Avi? E.g. replace "Ogg Theora" in my comment
above with "Avi Theora"?

Avi and Vorbis audio do not work very well together. I'm not sure if there are
even any DirectShow filters other than ffmpeg that support it and even that
has trouble keeping the audio in sync.

Xiph has them. Dunno if they're perhaps ffmpeg-based, but it seems unlikely.

They are not based on FFmpeg.

Matroska is probably the way forward.

Does it just show that I don't watch much video, or that I don't watch
much (any) pirated video, that I've never actually seen anything in a
Matroska container? (At least, not knowingly. I've never encountered an
odd-looking video file and run file(1) or similar tool on it and been
told, hey, this is Matroska.)

The answer is yes ;-)
