Hi Siva,
In general, if you want the highest quality, you should set fps to something quite high (24 is high), quality to 100 (no compression), and set bandwidth to 0 (meaning, use all available bandwidth).
Looking over the screenshare publisher docs, they’re missing the detail needed... I’m adding this to the backlog. For now, just use the WebcamPublisher as a guide to these settings (they’re roughly the same for both).
thanks
