Webcam Video Recordings
Combined this plugin with the Video Conference plugin and got a winning combination for the projects involving custom Webinar widgets. The Video Conference plugin solved the need for smooth communication channel over video, but there still was a need to have a feature to record those meetings for future reference. Webcam Video Recorder fulfilled that need.
VideoWhisper conference
This free version was very cost effective for the Chat room projects developed using Joomla. Also, it was a great addition for projects which required built-in support for webinars on private portals.

It needs a bit more in-depth documentation, but overall it is an awesome extension.
