Python : movie stream into pygame
4 mars 2019, par user1533267Quick challenge :
I’m streaming part of my desktop screen trough the network using the following :
Server
$ ffmpeg -f x11grab -s 800x600 -r 30 -i :100 -an -q 10 -f mjpeg - | nc -lp 5000
Client
$ nc <computer address="address"> 5000 | ffplay -
</computer>I would like to display the following stream inside my pygame opengl window on the client, I read some documents on pygame.movie and found :
"Load a new MPEG movie stream from a file or a python file object."
Would it be possible to load the stream into pygame ?
I need it to be as responsive as possible, and right now im seeing about 500ms lag.Any ideas ?
Thanks.
