Hi -

Since I presume you want a GUI around this program ... I would urge you to consider looking at a combination of GTK+ and the gStreamer interface:

A good example, if you need working code, is Cheese:

thanks a lot for helping.
But i think my problem is much simpler than this i am having a static .jpg file saved (captured from remote client camera mounted in other room, updated as 5 frames per sec) at the server side, i just want to display it on monitor(in a 640X420 window preferably) which simply show that image with refreshing when next image over right previous image that's it no operations other than displaying on screen are required.

thanks & regards
