performance hint: av\logging.pyx:232:5: Exception check on 'log_callback' will always require the GIL to be acquired.
Possible solutions:
1. Declare 'log_callback' 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 'log_callback' to allow an error code to be returned.
