What a fool of me, I never thought of sharing my problem here, never came to my mind that KOPETE has its own support forum anyways,since i installed UBUNTU 11.04, i have asked this question to almost all the biggest tech. forums regarding to solve my JASPER IMAGE CONVERSION PROGRAM ERROR while viewing/sending the camera from both sides. In CONFIGURE it works good for PREVIEW but when it comes to check the WEBCAM for other user or sending my webcam to them, it appears the error for JASPER IMAGE CONVERSION PROGRAM IS NEEDED. I have tried installing and fixing with all the possibilities available on the internet but it did not work,perhaps 11.04 is the reason but i am dying to resolve this issue soonest possible as i can't keep switching to WINDOWS just for the sake of WEBCAM . Please need HELP.
