| Hi,
I am new to this list and I hope you can help us out.
we are currently testing with FMS2 and are experiencing dropped frames .
We tets locally (LAN) so bandwidth sit not the problem, we also tried to =
lower the quality but=20
we still experience dropped frames.
CPU is never taxed more then 50%
Any ideas how to ensure that no frams are dropped?
Gerard

| Gerad,
Check your Camera.setMode() for FPS setting along with that of your
app. See if setting both to 15 helps.
Camera.setMode(160,120,15);
Also, try adjusting your Microphone.setRate();
The microphone is given priority over video, and so adjusting your
rate may help too. Chapter 6 in programming FCS provides some
insights as does Peldi's little blog.
HTH,
Bill

| A purely non technical suggestion would be to ensure that the subject
is properly lit. A webcam will work harder at trying to bring the
subject into view/focus if the room is poorly lit leaving little
contract between the person in front of the camera and the background
surroundings.
The fps will improve if the person on cam has a good light source
pointed directly at them.

| In the FMS2 xml server config file there's a client-server bandwidth limit
of 250Kb/s,
even if this is high, I have experienced some problems. Try an higher value,
example 10000Kb/s.

| Gerard,
Let me second Fabio's suggestion. Whenever that happens, just set the
server side BW up high using server side Client.setBandwidthLimit(),
and then bring it down so that you've got the optimum BW setting.
HTH,
Bill
