Do you use Ubuntu GNU/Linux distribution ? If you use the 7.10 (last version) it will be really simple to add support for our softwares.
Our LiveDVD is needed mostly for peoples who do not know anything about GNU/Linux.
The manual (PDF) was written by somebody outside the company. (Contribution) And this manual is about 333 model. So it's outdated. The 1.5.1 CD is outdated (on this CD MPlayer is compatible with up to 3MP, not 5MP) and on sourceforge you got files to recompile our CD from the original Knoppix.
Officially Elphel propose only sources on SF.net and the Knoppix based DVD 2.0
The easy way to install our softwares on a Ubuntu (the way i do) is to add those 2 lines to your /etc/apt/sources.list :
deb http://ppa.launchpad.net/polto/ubuntu gutsy main deb-src http://ppa.launchpad.net/polto/ubuntu gutsy main
apt-get update apt-get install mplayer vlc elphelogm
Feel free to contribute providing documentation on our wiki. We always welcome contributions.

Thanks Alexandre, Great advice! We will try it on Ubuntu (privately). I have 7.10.
However, due to Microsoft's dominatin in the Dutch educatinal market, virtually all Duthc primary schools use Windows on their desktop. Even our school cannot escape from it. That's why we choose Elphel. Becasue of it is independent from any OS. Dirk
Ok, on windows you can use FireFox and we have a windows precompiled MPlayer on our sourceforge. (MPlayer is compilet without GUI, so it should be started from CMD) Also last version of VLC for windows (or any OS) can play up to HD resolution (1920x1080).

Dear Alexandre, I followed your advice on a Dutch Ubuntu 7.10 and did it as root. The elphelogm package did not install.

This moring I tried the Elphel CD at school and had about the same error : connection refused.
We use VLC at school on Windowns and no luck too. Will try your precompiled Mplyer. How do we use Firefox with Elphel? Thanks for your help. dirk
Dear Alexandre, I donwloaded the mplayer from the Elphel Sourceforge site, unzipped etc. and ran it. Reults:

I really do not know what to do next. Dirk
Dirk, port 7070 was used on 333 camera model, now it's port 554, so you need to point mplayer or vlc to rtsp://192.168.0.9:554
Firefox can not be used for live video, only for configuring the camera. So what you need to do is :
1) open the camera interface with firefox, set the resolution to 1920x1080 (for VLC)
when you can start MPlayer or VLC on rtsp://192.168.0.9:554

Hello Alexandre, Are these lenses usable with our camera? http://www.order.conrad.com/cgi-perl/lshop.cgi?action=showrub&wkid=1195792342&ls=d&nc=&rubnum=a41.bl50.ap24.cc54&artnum=&file=&gesamt_zeilen=&shop= Kind regards, and have a nice weekend, Dirk
The last one should be usable. but i do not know about it's quality. The lens i sent you is a really good quality lens ~200 Euro. And you will not be able to find good quality lenses for less. What is the problem with this lens? Can you send me an image by e-mail ? --Alexandre.Poltorak 08:52, 14 March 2008 (CDT)
No, the last one is 1/3" - camera needs 1/2". And "usable" is rather broad term - lower resolution lenses can produce OK images (especially with partially closed iris), but still not the sharpest ones.--Andrey.filippov 10:14, 14 March 2008 (CDT)
What is the tucows.dll pls? does the camera stream in maximum 5MPix resolution? --Alexandre.Poltorak 12:34, 18 March 2008 (CDT)
