It demonstrates that an offsite server can be used and connected to by many clients who may be interested in a live stream of what is going on on a certain machine. This really increases the compression ratio. This implementation uses delta refreshes. Quit the server with a command line messageĬ:\Program Files\mosquitto>mosquitto_pub.exe -h "127.0.0.1" -t "server/quit" -m "0"

client is notified that there is a message on the screen grab topic.server publishes the base 64 string to the screen grab topic.server does a delta with the last image if possible.server base 64 encodes a compressed pickled numpy image.server is notified that there is a message on a topic for a screen grab.These scripts rely on image processing modules to do the heavy lifting The other script requests screen grabs and displays them. One script listens for a request for a screen grab. Here are two scripts that connect to the mosquitto broker. When the broker receives a message on the topic you are subscribed to it will send you that message. I recently discovered an interesting messaging broker/server called mosquitto ( ) In short, you make a connection to the server and subscribe to topics. I did not care to write the low-level socket code. I was interested in a python based screen sharing set of scripts. Thread = Thread(target=retreive_screenshot, args=(sock,)) Let me know if you find this acceptable, I am using the MSS module to prevent I/O. I just tried and it seems to work pretty well (Python 3). Is there a more efficient way? that casts the screen of computer no.1 and shows it at computer no.2 ?

T = threading.Thread(target = RetrFile, args = ("retrThread", c))ĭisplay_screen = pg.t_mode((1900, 1000))īasically my question is: how to share a screen between 2 computers, I don't know if the way of sending a lot of pictures using PIL is efficient and right. My client will get the picture (screenshot) from the server and "blit" it to The problem is that I can't send the screen in at least 24 fps, because when I take a screenshot with PIL (ImageGrab), something delays there. I'm trying to make a screen-sharing program in python. Hi I'm stuck and I did not find anything helpful on the internet.
