Vorbis - Jun 2003 - .ogg file extension for both audio and video?

Hi,

If I understand things correctly them Ogg is the wrapper format that
is also going to be used for Xiph's upcoming video compressor.

Does that mean that the .ogg file extension will also be used for
video?

This could present problems regarding mapping the .ogg file extension
to an application if for example I want audio to be handled by Winamp2
and video by something else.

This has been discussed in the past, but no definite conclusion was made. In
the mean time, Tobias' Ogg DirectShow filters were made, and people
apparently adopted .ogm as the extension for files that contain video
streams...

You could bind the .ogg extension to a "switcher-app" which would 
analyse the given ogg-stream and start a proper application to play it.

For an experienced developer it would be a fairly easy task to develop 
such a "switcher-app".

Ludovic 'Blacksun' Vialle, the main developer of the The Core Media 
Player, was once coding an application called 'Ogg Prak' as an ordered 
work from Emmett Plant. The proggie was coded in Delphi, only for 
Windows, and would allow the user to assign different applications 
depending on whether its an audio only or a video file.

The code should be in Xiph CVS, according to Emmett.

A "switcher" app doesn't solve the problem, though.
As a user, I'd like to tell from the file extension
if its audio or video. Using .ogg for both simply
sucks, IMO. Baaad idea.

Scenario: User installs ogg switcher app together
with a vorbis player. There is no ogg video player
around at the time. So although there is an associ-
ated app for .ogg, there are .ogg files it can't
play. Major drag. Most users will blame the ogg
package of being unable to play its own files. And
rightfully the will since this goes against the
whole concept of file extensions, no matter how
smart it was in the first place (I have yet to see
something better, though).

It's not as easy, though. From a users POV, after installing
a player for Ogg Vorbis, I expect it to register with windows
so it plays Ogg Vorbis streams when I double-click them. Period.
Installing an Ogg Theora play has to register it so it plays
when I double-click Ogg Theora streams. Period. You can't expect
end-users to do anything more complex than launching an installer.
Letting users choose whatever extensions they want is sure recipe
for desaster.
Nobody said you have to stick to three letters. using .oggvorbis
and .oggtheora would be fine. The only problem I can see are
portable devices displaying filenames instead of embedded IDs.
