What is Real-Time C0llaboration
All this happen, real-time. If you are unsure of what “real-time” collaboration is, let me explain that real quick.
A collaborative editor is a software application that allows several people to edit a computer file using different computers. There are two types of collaborative editors, real-time and non-real-time. Real-time collaborative editors allow users to edit the same file at the same time. ( wikipedia )
So, when you say watch one video, in real-time, you are watching the same video, on two different computers, two different locations. Suppose you pause the video on your computer, same will happen on your friend’s computer too. Your friend can see every mouse movement every click you make.
Once you install the plugin, to start a video chat, just click on the “Video & more” menu at the bottom of your Gmail chat window, and choose “Start video chat.” You’ll have a few seconds to make sure you look presentable while it’s ringing, and then you’ll see and hear your friend live, right from within Gmail
How to Popuout video : When you are on a chat, you know how you make it a separate window, and continue to chat , this is possible with video chat also. The follow image shows where you should click to pop the window out from your gmail inbox.

Old Post : Using Your Webcam to take picture for profile photo
Even when we use gmail and gtalk for most of our chat and email, we often go back to Yahoo, for video and Webcam. What if you have webcam also, on your gtalk or gmail ? Well, don’t get excited, the feature is yet to be announced. But, I think, its on its way. Reason ? Google announced recently, that Google Talk gadget users will now be able to take a picture directly from the webcam to use as their profile picture gtalk.
” Currently, this feature only works in the Google Talk gadget, but will set your picture across the Google Talk network, including in Gmail.”
Yahoo never allowed us to use webcam from a linux machine, will google enable that feature ? Thats my concern now.
How To
From the Google Talk gadget, click on your Google Talk picture, and select the “Take Photo” option. You’ll see the image from your webcam appear, and you’ll be able to take and retake pix to your heart’s content. When you get that perfect shot, just click “Save” to set it as your picture.
