Vi. Supplement

1. Solutions for a single meeting room with only four participants:

Since openmeetings can only be attended by four persons in a conference room by default, I don't know what foreigners think. No way. You can only download the opeenmeetings source code for modification. Openmeetins client source code is an "openlaszlo" application, forced to study openlaszlo, it feels like a good Ria solution. You only need to modify videoconference/xmlcrm/content/conference/roomlistitem. the value of the maxusers variable in the LZX file is enough, but you will find that the number of cameras in the meeting room is still 4. What should I do? You only need to modify videoconference/xmlcrm/content/conference. in the LZX file, refer to the original camera layout to add the number of cameras. However, the number of cameras is not suitable for too many, because the traffic of multiple cameras will be quite large and the server pressure will be too high, in addition, the average video conference is also composed of several leaders and several small soldiers, so the small soldiers don't need a camera. Just watch and listen. In http://code.google.com/p/openmeetings/wiki/BuildSources? TM = 4 contains the openmeetings source code download method. You can use SVN client tools to connect to the http://openmeetings.googlecode.com/SVN/branches/dev/Laszlo/client/download browse client code; SVN client connection http://openmeetings.googlecode.com/svn/branches/dev/xmlcrm/get the back-end service javacode

2. debug openmeetings

Log on to the openmeetings homepage, click profile, select Chinese simplifiled, and click Save in the upper left corner. The setting is complete. If you want to make it take effect immediately, You need to exit and log on again to make it take effect.
