I am going to explain one coolest video conferencing software on web, ekkotv. One of the attractive feature is that there is no need of a login to initiate chat conversation. You can enter into group chat with your 2 friends provided the nicknames. When you start a conversation you are entitled with a URL, You can share the URL to your friends for group chat.
The main feature is the application record the web cam audio and video, broadcast to your 2 friends from web browser, however the broadcasting is pretty sluggish I appreciate the application since it record web cam video and audio from a web browser. The recording application is developed in flash and asp.net. I guess the media server used in the backend will be RED5, because Adobe’s media server is pretty costly.
You can start the video conferencing now just enter a nickname and start conference. The URL entitled with you is shared to your friends using any medium like gtalk, yahoo IM or email. The application is lacking one main feature, we can’t invite your chat friend directly since there is no login session instead sharing a URL, so we need to use some other software for sharing the URL.
