video format

use setMode to increase the quality. By default it's locked to 16 kbytes/sec.

Use something like setMode(80000,90) to make your video record at 80 kbytes/sec and quality setting "90". 90 is like jpeg compression ; the higher the number the better the quality but the lower the compression resulting in less frames/images per second. You should fiddle al lot with setMode to get a good quality setting or even make a custom combobox and let people set their own quality and bandwidth "per camera".

Thanks very much for your replay.
I do not understand my the video I get is so poor in quality even locally with one connexion.
So my problem so far is how I can improve the video settings.
The webcam I am using is logitech pro 400 which is a rather good camm.
The video is quite good using 200 x 200 format but it gets very distorted when I use a 400 x 400 format.
For this I used the AV prersence component.
Thanks very much for your concern

Everything is possible. You can transmit 40 Mbit video to a single client if that client has enough bandwidth and your server enough cpu-power to deliver the stream. Afaik the videocodec has no size (pixels, width, height) restriction.

It all depends on the bandwidth between server and client en cpu power on client and server. If you want to publish 10 streams on a Dual Xeon server you won't have a problem delivering streams up to 4 Mbit per piece. But if you want to stream 1000 streams on a small P3 800 Mhz system with a 8 Mbit uplink you will hit the limit in no time. I'm confident you can make the proper calculations yourself.

A decent FMS server can deliver 1000 streams and/or up to 40 Mbit thruput (thanks to the license) , on paper.
