Test result : 80,5080,1935

FAQ 1
Q : How to change my video size
A :
If you resize your own video-pod in the conference much larger and then synchronize the stream, all clients will get a better picture (it also needs more bandwidth, as it will take the actual new height / width numbers to publish your stream)

FAQ2
Q : When I upload a doc/ppt/xls file, it shows error message
A : Make sure OpenOffice is running
How to enable OpenOffice
C:Program Files (x86)OpenOffice.org 3programsoffice.exe -headless -nofirststartwizard -accept="socket,host=localhost,port=8100;urp;StarOffice.Service"
netstat -an |find /i "8100"

FAQ3
Q : how can I change the word “OpenMeetings" with my company name or logo?
A :
c:openmeetings_1_8_2_r4283webappsopenmeetingsconfig.xml
Line 54 <currentappname>OpenMeetings</currentappname>
Q : Can I upload a html tag? For example: <img src = "My immagine.png“>
A : No, just simple strings.

FAQ4
Q : How to change default language?
A :
Database : openmeetings
Table : configuration
Configuration_id=12
comment_field
Default System LanguageID
Conf_key=default_lang_id
Conf_value=1 => 12
Table : fieldlanguage
1 english
12 chinese traditional

FAQ5
Q
I'm about to put the OpenMeetings running for 200 students. Is there any advices (specifications) about what customizations should be done in my Linux configurations (and what kind of hardware would be desirable)
A
For 200 students you should have:
3-4 GB RAM, 2-3 GHz Dual Core CPU
Bandwidth depends on usage scenario,
1 audio/video connection produces around 70 KByte/sec
1 screen sharing produces around 90 KByte/sec
4 participants in a conference room where everybody has audio and video turned on produce:
4 * (4-1) stream=12 stream=12*70KByte/sec=840KByte/sec@Server side
100 participants in a webinar room where 1 is presenter and other just watch:
1 Stream uploading to the server
100 Streams downloading from the server.
And so on ...

FAQ6
Q : View only screen sharing?
A :
For now you can just remove the moderation from the other users, and they won't be able to do remote control.
Only Moderators or if you directly give that right to other users, they are able to do remote control on the screen and not only view.

FAQ7
Q
Sebastian, I understand everything you talk. But could you tell me please if OpenMeetings is integrated ONLY with OpenSIPg server? Or it could work with any SIP-server that has similar architecture?
A
It could work with any SIP server that provides the needed API functionality to create SIP users and conference rooms.

FAQ8
Q : Is there any setting available to move whiteboard toolbar on left hand side vertical?
A : You can simply drag and drop it.
Q : Can it be automatic shift to left hand side vertical.
A : There is no such option, you would need to customize it.

FAQ9
Q :
I was hoping to test a tablet with this so purchased an htc flyer to see how things would work out. So far, I have not found a way to display my tablets camera to others in a flash conference. I can view the conference but I cannot enable the camera to send video. Is there a separate application needed on the server side to allow a tablet which doesn't appear to have flash enabled video sending or something else? Thanks.
A :
I don't think there is anything officially released for tablets yet.
