      performance hint: av\logging.pyx:232:5: Exception check on 'log_callback' will always require the GIL to be acquired.
      Possible solutions:
          1. Declare the function as 'noexcept' if you control the definition and you're sure you don't want the function to raise exceptions.
          2. Use an 'int' return type on the function to allow an error code to be returned.

I have no idea about this error I think. What can I try next?
