Thank you ukulele,Humvee & mattman..
well, I have found it. I had asked a similar question on another forum also & one guy has given me a good free software link.
Try this one.
Fake Webcam
Stream/play videos and movies on Yahoo, MSN, AOL, Paltalk, ICQ, Camfrog, and on all messengers instead of actual Webcam. It streams videos and movies on your messenger just like an actual Webcam. You don't need to have a Webcam for Webcamming. Enjoy pretending a teenage girl or someone you want to be. Your chat mate will never figure out that it's not a real Webcam.
It enables you to:
* Play pre-recorded videos without even having a physical webcam.
* Shared your video clips with family and friends through your instant messengers.
You can download it from
