Hi Walter,

I think it is a confusion created originally by mp3 which is both an
encoding and a format.

Then the ogg container format name for some time was used exclusively
for vorbis audio files which led people to a belief that .ogg means audio
when it does not.

A vorbis player has even got name "ogg123" which is very confusing
for people not aware of the internals...

On the other side .ogg is about the same as .avi - it can contain a lot
of things, not necessarily theora or just sound or just video.

So imho there is nothing wrong with .ogg naming, though the contents type guess
is impossible. As bad as with .avi where you can not guess by the name
which of the myriads of video codecs has been used.

You might want to add other parts into the name which tell about the contents


or just


or may be even


when xdiv-related patents wear out?

or something else.

That's exciting to see.
