B4J Question Creating a Remote Desktop solution with B4J (PC to PC)

[wonder]

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.

Sending each screenshot as a separate image may require too much bandwidth.
30 * 300kb = 9mb per second. The correct way is to use a video format.

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?

Is it possible that an encoder video can be faster than sending single frames? I don't think so.

I don't think that there is such a library.

Maybe not faster... but, since it will certainly compress the data, less bandwidth will be necessary!

a 300kb screenshot in jpg is already compressed. There is not much to compress

 

[Cableguy]

Yes, but you need to compare the 30 frames/s (300k * 30) per second against 1s of video encoded!

This open-source project may be a good starting point:
