Video Conference
The Video Conference web based software can easily be used with Moodle sites to build live video interactive virtual learning management systems .
Video Conference is great for bringing physically distant people together in meetings, conferences, trainings, live events, coaching, recruiting, consultations and of course casual community chat.
This Video Conference edition integrates into Moodle as an activity module so video conference rooms can be added to courses as activities.
We recommend using this with latest Moodle version. Was tested with Moodle 2.0.1+. All module php integration code is provided with full source code under GPL (free to use and edit).
You will find multiple details about Moodle Video Conference module activity on this documentation page: demo, how to install, how to configure, how to use, activity settings and permissions, how to customize, how to uninstall/upgrade, all VideoWhisper plugins for Moodle.
Before installing, make sure your hosting environment meets all requirements. In addition to Moodle web hosting requirements, these applications demand a supported RTMP flash media server (Red5, Wowza, Adobe) where VideoWhisper rtmp side should be deployed. If you're not hosting RTMP side with VideoWhisper.com managed plans/servers go to RTMP Application Setup for rtmp side installation instructions.
Can you please confirm or let me know where I can find the below information?
I need to confirm the video conferencing has these items before I can install the plugin as we are required (by a government organisation) to have tools these for our online classes:
1. Chat
2. Forum
3. Email
4. Progress tracking
5. Calendar
Many thanks,
Jess
