In my use case I would like to record the screen activity and send it to server [not live]. I looked at few blogs/sample demos for this. But I couldn\'t find anything relate
As suggested by @mido, in the client side I would use MediaRecorder API. Another option would be to record in the server side. For the latter option, you can use some open source media server, like [Kurento] (http://www.kurento.org/).
