wonder Expert Licensed User Longtime User Jul 17, 2016 #1 I'd like to create a very very simplified remote desktop application for my personal use. My idea: - Screenshot my PC at home 30 times per second - Continuously send the screenshots to my laptop - Receive mouse/keyboard input from the client - Local network and Internet compatible (UDP? TCP/IP?) So... Is it possible? If so, would the jAWTRobot lib be up for the job? Would such performance be achievable?\ Many thanks in advance. Last edited: Jul 17, 2016

The correct way is to use a video format. Upvote 0

wonder Expert Licensed User Longtime User Jul 18, 2016 #3 Thank you, I think I understood everything what's necessary except how to encode the PC output into a video format... Is there a library for that? Upvote 0

DonManfred Expert Licensed User Longtime User Jul 18, 2016 #7 a 300kb screenshot in jpg is already compressed. There is not much to compress Upvote 0
Cableguy Expert Licensed User Longtime User Jul 18, 2016 #8 Yes, but you need to compare the 30 frames/s (300k * 30) per second against 1s of video encoded! Upvote 0
