MSS, Python: Maximum number of clients reachedSegmentation fault (core dumped)

Question

I use MSS for Python for capturing screenshots rapidly on my computer, but when putting the image capturing inside a while loop:

import mss
while True:
    sct = mss.mss()

I get an error message Maximum number of clients reachedSegmentation fault (core dumped). How do I solve this?

Answer 1

You should use the context manager:

import mss

with mss.mss() as sct:
    while True:
        # ...

Answer 2

The solution is simple, and I think it has to do with not closing the mss feed properly. Simply add an sct.close() at the end of each iteration:

import mss
while True:
    sct = mss.mss()
    sct.close()
