Opie is based on qpe and uses QT-embedded from Trolltech. It stands for
Open Palmtop Integration Environment. Opie, Qtopia (qpe), Intimate and
familiar are the four most favourite distro's for the iPaq. Opie and
Qtopia both use familiar as there base, but without X11. Compaq Research
is busy with getting Opie and Qtopia on top of X11.
Opie (and Qtopia) are better equiped as Personal Information Manager
then a complete familiar is at the moment. They are clearly ahead with
respect to functionality. I think it is worth to get vlc working on that
(and as well as on familiar).

Last week I had a demo with iPaq and vlc-0.3.1. I used as streaming
server vlms and that worked fantastic. The audio did not work perfectly
it sounded like audio underruns, so I guessed we still had to do the
video part. But as you write below that a lot of work has already be
done. I guess an extra look at the audio part can't hurt. 

So I think, I'll have to look at the audio again and do some testing.

A pitty that you do not have as much time for that kind of work as you
did have. I'll try to spend some more time on this and get an up to date
ipk out. Do you have some patches for SDL on iPaq? Or is the
good enough.

So the complete video path is not integer based yet? 
If that is so, then I think we should get the native MPEG and ac3
decoder integer based. Is that possible?

A vout_qte based on purely QT-embedded and a qte native UI too would be
nice. I have some ideas for the interface and only need time to do it.
Some help can not hurt either ;-)
