can we add any thumbnail on the rovideoScreen?

No, but if you use roVideoPlayer in combination with roimageCanvas or roScreen you can display a thumbnail on the roScreen or roImageCanvas, in front of the video.

Is there a particular reason you want to use roVideoScreen instead of roAudioPlayer to play your audio file? Unless you have a need for built-in position notification (over tracking it yourself with an roTimeSpan), that seems like an odd choice. I'd suggest using roAudioPlayer in conjunction with roImageCanvas to do what you've described.

But i don't know how to show a progress bar on roImageCanvas.
If I uses a rectangle for progress bar then how to add a dynamic rectangle on roImagecanvas.
